1 ClimateMaster Water-Source Heat Pumps Vertical Stack (VHS) Series 0 . 7 5 t o 3 To n Ve r t i c a l H i - R i s e U n i t s COMMERCIAL HVAC The ever-changing environment of commercial construction offers exciting breakthroughs in technology and materials, but it is not without some heartburn. Today, owners, architects, and contractors face many challenges in the design and construction of their projects. Challenges such as usable space, indoor air quality, energy efficiency, maintenance costs, building longevity, and the LEED® program all come to the forefront of the design process. When considering the solutions to these challenges, the type of HVAC system chosen directly affects each one. USABLE SPACE It has been said that the reason real estate grows in value is because no one is making any more. As cities continue to grow and spread out, the value of maximizing usable space becomes increasingly important. When selecting an HVAC system, you positively or negatively impact the usable space on a project. As an example, VAV (Variable Air Volume) systems utilize complicated ductwork systems along with extensive equipment rooms to deliver conditioned air into the building space. Additionally, VAV duct systems many times require more ceiling height which increases floor-to-floor space thus increasing building costs. By comparison, ClimateMaster Water-Source and Geothermal Heat Pump systems require little to no equipment room space and use a very simple, compact, and independent ductwork system. INDOOR AIR QUALITY As important as the actual temperature of a building space is, the quality of air within that space is equally important. The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) has implemented Standard 62, which requires significantly higher amounts of fresh outdoor air for buildings. The challenge now becomes how to properly introduce, condition, and deliver this fresh air into the building space. Traditional options like two- and four-pipe Fan Coil systems must be up-sized significantly to handle the additional conditioning load. This means larger, more expensive units, larger, more expensive piping, and larger more expensive boilers and chillers. In comparison, ClimateMaster systems offer a variety of options that can actually lower the overall system size, introduce 100% outdoor air, and lower system usage cost.
2 ENERGY EFFICIENCY Today's offices equipped with computers, copiers and other office tools can dramatically affect the heating and cooling load of a given space. When considering heating and cooling loads, rising energy costs demand an HVAC system that is efficient while building designs require a system that is also flexible. ClimateMaster has a solution for practically any application, and does so with some of most energy efficient HVAC systems available on the market today. In fact, all of ClimateMaster's products either meet or exceed the new federal mandated efficiency minimums. MAINTENANCE COSTS Complex systems such as two- and four-pipe fan coils and VAV systems require advanced maintenance and the trained personnel to perform it. Large equipment rooms filled with chillers, air handlers, or large-scale boilers require personnel for monitoring and maintenance, which consume building space and leasing profits. The effect to the bottom line becomes significant when considering the potential of a complete system failure along with costly parts and equipment replacement. However, Water-Source and Geothermal Heat Pumps require very little monitoring and maintenance - aside from routine filter changes. With factory installed DDC controls, the entire building can be accessed via any web-enabled computer for monitoring and set point control. No muss, no fuss, no worries. BUILDING LONGEVITY New innovations offer longer life expectancies for today's buildings. You should expect the same from the HVAC systems being placed inside these buildings. However, when it comes to longevity, not all systems are created equal. Complex chillers and air handling systems often have a large number of moving parts that will wear out over time. Water-Source and Geothermal Heat Pumps offer the advantage of very few moving parts. Fewer moving parts lower the occurrence of parts replacement and extend equipment life. This simplicity of design allows ClimateMaster systems to provide average life spans of 20 years or more. In fact, there are a number of ClimateMaster units that are still performing after 50 years - providing the continual comfort our customers have come to expect. The Smart Choice for Energy Efficiency MANY CHOICES, ONE SOLUTION When choosing a HVAC system for a project, there are four basic types from which to choose. FAN COILS Fan coil systems are comprised of water-to-air coil air handlers connected via a two- or four-pipe insulated water loop. Fan coils require complex chillers and boilers to provide water loop fluid in a particular temperature range (i.e. chilled water for cooling and hot water for heating). Two-pipe fan coils have a major disadvantage as control is substantially limited to whatever mode the system is currently set at (i.e. cooling or heating). A four-pipe version can be installed that requires both chilled and heated water to be available at the same time. Four-pipe systems also require twice the piping and twice the circulation equipment of a two-pipe system, which makes a four-pipe system one of the most expensive systems to install. VARIABLE AIR VOLUME (VAV) Variable Air Volume, or VAV, is one of the most common types of HVAC systems used in large commercial buildings today. A typical system is usually comprised of a large air handler, central ductwork system, and a relatively large equipment room. Conditioned air is distributed throughout the building via a central ductwork system and is regulated via dampers in each space. VAV systems typically have a higher first cost than Water-Source Heat Pumps, and may have similar operating costs, resulting in overall increased life cycle costs. SYSTEM COMPARISON
Maintenance Requirements ROOFTOP Rooftop systems are similar to VAV systems in that they use a central ductwork system to distribute conditioned air into the building space. However, instead of one central unit, the system is comprised of multiple units which can be tasked for different conditioning requirements. Rooftop systems usually require additional structural reenforcement as well as cranes or other lifting equipment to place the units. Control in a particular zone is limited to what the system is currently set to (i.e. cooling or heating). Rooftop installation costs are low to moderate, but operating costs are typically 50% higher than Water-Source Heat Pumps. Additionally, the systems are exposed to the elements and are subject to damage and vandalism. WATER-SOURCE AND GEOTHERMAL HEAT PUMPS Water-Source and Geothermal Heat Pump systems are comprised of individual packaged units that transfer heat via a single- or two-pipe water loop. Each unit can be used in either heating or cooling mode year-round and loop temperature is maintained via a boiler/tower combination or earth-coupled loop. Each zone has complete control of its heating/cooling mode and each unit is independent from the others. This means if one unit goes down, the whole system is not affected. Controls can be as simple as one unit, one thermostat. Water-Source and Geothermal Heat Pump systems are the most energy, cost, and space efficient of any system in the industry.

Heat is moved through an interconnected water loop and either rejected through a cooling tower, or put to work in other areas. Each unit is an independent, packaged system, eliminating the chance of a total system failure. If one unit goes down, the other units are not affected. Conveniently located above the ceiling or in a closet, units can be easily accessed. SYSTEM MODES Water-Source Heat Pump systems can operate in one of four modes depending on the space conditioning requirements. The versatility of operation allows WaterSource Heat Pumps to show their full potential as a solution for customized comfort and flexibility. COOLING MODE to maintain a constant temperature of 60 to 70°F in the water loop during high heating demand months. Within this temperature range, the units can operate in either heating or cooling mode. BALANCED MODE The system extracts heat from the air and rejects it into the water loop through the coaxial refrigerant-to-water heat exchanger. This heat can either be moved to a different part of the building to satisfy a heating mode requirement, or be rejected out of the building via a cooling tower. HEATING MODE The system extracts heat from the water loop through the coaxial heat exchanger and compresses it to a higher temperature. This heat is then transferred into the air through the air coil and used to condition the building space. A nominally sized boiler is often used
4 A mixture of units in heating mode and units in cooling mode create a constant temperature in the water loop. In Balanced Mode, there is no need for heat injection or rejection via the boiler or cooling tower. The heat is simply moved from one zone to another. DEHUMIDIFICATION MODE The system, using a multi-speed blower and separate humidistat, slows the air movement across the air-coil to extract moisture and provide a more comfortable space. An additional reheat coil is available on select products for those climates where high humidity is a problem. The Smart Choice for Energy Efficiency A WATER-SOURCE EXAMPLE As an example of how Water-source Heat Pumps can handle a variety of different applications, the building shown to the right is a fictional bronze statue foundry company in the midwest portion of the United States. The first floor comprises their production floor and office space. The second floor of the building is reserved for future use. The cooling tower and boiler work as needed to maintain an average loop temperature between 60 to 95°F. Water-source Heat Pumps can efficiently operate in either heating, or cooling mode under these conditions. This gives individual and specialized zone control for maximum comfort and the ability to change operation modes as needed. A mixture of units in heating mode and units in cooling mode create a constant temperature in the water loop. In Balanced Mode, there is no need for heat injection or rejection via the boiler or cooling tower. The heat is simply moved from one zone to another. WARM WEATHER (HIGH COOLING DEMAND)

Who is ClimateMaster? ClimateMaster emerged from the marriage of several Water-Source heat pump companies in a blending of strengths to form a focused organization. For over 50 years, we have been focused on enhancing business and home environments around the world. Our mission as the world's largest and most progressive leader in the Water-Source and geothermal heat pump industry reveals our commitment to excellence - not only in the design and manufacture of our products, but in our people and services. CLIMATEMASTER DESIGN From concept to product, ClimateMaster's Integrated Product Development Team brings a fusion of knowledge and creativity that is unmatched in the industry today. Drawing from every aspect of our business: Engineering, Sales, Marketing, and Manufacturing, our Development Team has created some of the most advanced, efficient, and versatile products available. INNOVATION, CONCEPT, NEEDS Great products are born from necessity. Whether it is a need to reduce sound, fit in a smaller space, make easier to service, achieve better efficiencies, or due to changing technologies, or new government regulations, ClimateMaster leads the industry in advancing the form, fit and function of Water-Source and geothermal heat pumps. Our Design Team continually strives for even the slightest improvement to our products. It is this continual drive for excellence that sets ClimateMaster apart from all other manufacturers. START TO FINISH At ClimateMaster, every product development project begins with a comprehensive set of specifications. These specifications are a culmination of input from the market, a specific need, or a number of other factors. From these detailed specifications, prototypes are constructed and testing begins. After a rigorous testing period in ClimateMaster's own state-of-the-art lab facility, the data is compared to the project specifications. Once the Design Team is satisfied that all of the specs are met, the unit is sent to the production department for pilot runs. After the
6 pilot runs are completed, unit literature is finalized and the product is released to the marketplace. Every unit we produce follows this strict and sequenced path insuring no stone is left unturned, and no detail is missed. CLIMATEMASTER PRODUCTION Innovative products demand innovative manufacturing processes. ClimateMaster's integrated production process combines every aspect of the manufacturing of our equipment into an organized, balanced, and controlled whole. FABRICATION Every sheet-metal component of a ClimateMaster unit is produced in our fabrication department. Panels are precisely constructed of galvanized or stainless steel using computerized cutting, punching, and forming equipment. This precise fabrication means a tighter fit that makes for a more solid unit and reduced vibration, which equals reduced noise. On certain series, an optional epoxy powder coating is then applied to increase corrosion resistance and enhance the look of the unit. The final step is the addition of fiberglass insulation to the inside as an additional layer of sound deadening. This insulation meets stringent NFPA regulations, and includes antibacterial material. ASSEMBLY ClimateMaster's 250,000 square foot production facility produces over 50,000 units per year using the most stringent quality control standards in the industry. Each unit is assembled under the close supervision of our Integrated Process Control System or IPCS. This multi-million dollar computer system watches each unit as it comes down the assembly line. To back up the IPCS system, our Quality department is stationed on each line and performs random audits not only on the units, but also on component parts. All component parts must pass each and every quality checkpoint before a unit is packaged and shipped. These systems and processes are maximized due to the comprehensive and ongoing training every employee receives from the date they are hired. The Smart Choice for Energy Efficiency COMPONENT PARTS To produce a quality unit, you have to start with quality components. ClimateMaster's purchasing department is relentless in its search for the best components for our products - while securing these components at prices that keep costs low. Any new component must go through a grueling testing phase before it ever sees the production line. Working closely with vendors and their engineers, we continually find new ways to not only improve our units, but to ensure component quality as well. Sister companies like KOAX, who produce our coaxial heat exchangers, allow ClimateMaster to provide components specifically designed for our applications CLIMATEMASTER CERTIFICATION ClimateMaster leads the industry in product awards and certifications. From 100% Air-Conditioning and Refrigeration Institute (ARI) performance ratings to industry awards for innovation, ClimateMaster applies cutting-edge technology to every product we design and manufacture. ClimateMaster's new Tranquility 27TM series has won multiple awards and is taking the industry by storm. Hot off the heels of winning The News Bronze Dealer Design Award, the Tranquility 27TM won Best of Show at ComforTech in September 2004. You know you are doing great things when a lot of people tell you so. ENGINEERING LAB FACILITIES ClimateMaster has one of the largest testing facilities of any Water-Source heat pump manufacturer. Innovation and product improvements are a mainstay of the ClimateMaster Engineering Lab. Our people are what make the difference in the development of superior products in a timely manner. Our certified facility has six automated test cells capable of testing a wide variety of unit types under varying conditions. These cells are capable of producing data twenty-four hours a day, seven days a week. The development time of equipment is significantly reduced allowing ClimateMaster Engineers and Lab Technicians to spend more time on the actual development process. This team effort has
7 allowed us to maintain a high degree of competence in our industry. Our test cells and test equipment are calibrated and certified periodically, per recognized industry standards, to insure the data is accurate and repeatable. In addition to testing new concept units, the lab continually audits production units throughout the year to insure quality performance and reliability. INDUSTRY AFFILIATIONS AND ASSOCIATIONS ClimateMaster works closely with the International Standards Organization (ISO), the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE), the Canadian Standards Association (CSA-US), the Electrical Testing Laboratories (ETL), and Conformité Européene (CE) to insure that our equipment not only meets the highest performance standards, but meets the highest industry standards as well. In a recent milestone, ClimateMaster celebrated three consecutive years of 100% success rate in ARI's performance certification program.

CXM Our standard CXM control board comes programmed with ClimateMaster's Unit Performance Sentinel (UPS) which monitors unit performance and notifies the owner of potential unit problems before a lockout occurs. Additionally, the CXM's eight standard safeties protect the unit from damage. · Anti-Short Cycle · Low Voltage · High Voltage · High Refrigerant Pressure · Low Refrigerant Pressure (Loss of Charge) · Air Coil Freeze (Excluding GC Series) · Water Coil Freeze · Condensate Overflow DXM Our enhanced controls option, the DXM control board offers all of the advantages of the CXM board but adds the following additional features: · Multi-Stage Operation · Night Setback · Emergency Override · Reheat Control · Boilerless Electric Heat DDC CONTROLS Factory mounted LONWorks or Multi-ProtoCol (MPC) DDC controllers are an available option on all ClimateMaster products. These controllers give owners the ability to implement a variety of building automation systems such as BACnet, ModBus, and Johnson N2. Through a web enabled PC, individual units, unit zones, and entire building systems can be monitored and controlled with the click of a mouse. The systems provide unit status, set-point control, performance curves, and fault indications. CONFIGURATIONS No other manufacturer provides as many size,
8 The Smart Choice for Energy Efficiency performance, configuration, and cost options as the ClimateMaster family of products offers. From our smallest horizontal unit in the GCH006, to our largest vertical in the GLV300, to our Rooftop series with available 100% make-up air (when mated with the Rx ERV), to the console, water-to-water, and two-stage Tranquility 27TM, we have a unit to fit your application. SOUND Prior to the recently adopted sound standard ARI 2602000 there had been no standard for the evaluation of Water-Source heat pump sound performance. Also, those manufacturers who did generate and publish their own sound data, did so in their own labs making it difficult to have the data independently certified and accurate comparisons were therefore, impossible. Now that a standard has been established, it is critical to compare the data correctly. If data from two manufacturers is compared using different test procedures, results are not comparable. ClimateMaster has tested its product line for both ducted discharge and free inlet air combined with case radiated tests. Comfort has never been so quiet with our intelligent sound design. Our products use a variety of technologies to maintain our lead as the quietest units in the industry. DUAL LEVEL VIBRATION ISOLATION ClimateMaster units use an exclusive double isolation compressor mounting system. This dual level isolation deadens vibration and provides quiet operation. TORSION-FLEX BLOWERS Blower motors ,on select models, are mounted with a unique torsionflex mounting system which not only allows for easy service, but also reduces vibration from the blower motor during operation. ULTRAQUIET ClimateMaster's optional additional sound suppression package enhances our already excellent sound performance through the use of dual density acoustical insulation and other strategically placed sound attenuating materials. No other manufacturer's mute package comes close to matching the performance of the UltraQuiet package. E-COATED AIR COILS All ClimateMaster Water-Source heating and cooling systems (excluding the RE series rooftop) are available with an E-Coated aircoil option. This process provides years of protection against coil corrosion from airborne chemicals resulting from modern building material outgassing and most airborne environmental chemicals. In fact, ClimateMaster's exclusive E-Coated air-coils enhance corrosion protection to nearly 20 times that of a traditional uncoated coil.*
* Test based upon ASTM B117 Salt Spray test hours. CLIMADRY REHEAT Continuing to lead the industry in IAQ (Indoor Air Quality) solutions, select ClimateMaster units are available with an innovative method (patent pending) of reheating the air. The ClimaDry microprocessor-controlled option will automatically provide 100% reheat by adjusting the amount of reheat capacity based upon supply air temperature. This new approach to reheat provides dehumidified, neutral temperature supply air, while eliminating the problem of overcooling the space when loop temperatures drop. All components are internal to the unit, saving space and keeping installation costs low. A simple humidistat or DDC controls activates the option. VOLTAGES ClimateMaster units are available in a wide variety of commercial voltages, providing maximum flexibility in building design. Available voltages are as follows: · 208-230/60/1 · 208-230/60/3 · 265/60/1 · 460/60/3 · 575/60/3 · 220-240/50/1 · 380-420/50/3
* Not all units are available with every voltage combination shown above. ACCESSORIES ClimateMaster offers a complete line of accessories to complete any project, including hoses, thermostats, valves, pumps, fittings, controllers, sensors, filters and more. 9 ClimateMaster Water-Source Heat Pumps Vertical Stack (VHS) Series 0 . 7 5 t o 3 To n Ve r t i c a l H i - R i s e U n i t s THE VERTICAL STACK (VHS) SERIES The VHS series offers an innovative, labor-saving solution for spaces where individual, quiet control of the heating and cooling system is important. VHS units' pre-piped risers and pre-wired cabinets are especially ideal for multi-story buildings. Cabinets can operate as stand-alone "ductless" systems, or can be ducted to an adjacent room, making them convenient for low-rise buildings as well. The VHS series meets ASHRAE 90.1 efficiencies, yet maintains small cabinet dimensions. Available in sizes 3/4 ton (2.6 kW) through 3 tons (10.6 kW) with numerous cabinet, water piping and control choices, the VHS series offers a wide range of units for most any installation. The VHS has an extended range refrigerant circuit with a TXV refrigerant metering device. Standard features are many. Microprocessor controls, galvanized steel cabinet, torsion-flex blower motor mounting, and e-coated air coil are just some of the features of the innovative VHS series. ClimateMaster's exclusive double isolation compressor mounting system makes the VHS series the quietest vertical stack units on the market. Compressors are mounted on vibration isolation springs to a heavy gauge mounting plate, which is then isolated from the cabinet base with rubber grommets for maximized vibration/ sound attenuation. Options such as high static fan motor for ducted applications, DDC controls, internal pump and factory-installed water solenoid valves allow customized design solutions. The VHS Series console water-source heat pumps are designed to meet the challenges of today's HVAC demands with a low cost/high value solution.

The performance standard ARI/ASHRAE/ISO 13256-1 became effective January 1, 2000 and replaces ARI Standards 320, 325, and 330. This new standard has three major categories: Water Loop (comparable to ARI 320), Ground Water (ARI 325), and Ground Loop (ARI 330). Although these standards are similar there are some differences: Entering Water Conditions Changes Entering water temperatures have changed to reflect the centigrade temperature scale. For instance the water loop heating test is performed with 68°F (20°C) water instead of 70°F. Entering Air Condition Changes Entering air temperatures have changed to reflect the centigrade temperature scale. For instance the cooling tests are performed with 80.6°F (27°C) dry bulb and 66.2°F (19°C) wet bulb entering air instead of the traditional 80°F DB and 67°F WB entering air temperatures. 80/67 and 70 data (as presented in performance data on pages 16-26) may be converted to the new ISO conditions of 80.6/66.2 and 68 using the entering air correction table on page 14. Pump Power Correction Within each model, only one water flow rate is specified for all three groups and pumping watts are calculated using the following formula. This additional power is added onto the existing power consumption. Pump power correction = (gpm x 0.0631) x (Press Drop x 2990) / 300 Where 'gpm' is waterflow in gpm and 'Press Drop' is the pressure drop through the unit heat exchanger at rated water flow in feet of head. Fan Power Correction Fan power is corrected to zero external static pressure using the following equation. The nominal airflow is rated at a specific external static pressure. This effectively reduces the power consumption of the unit and increases cooling capacity but decreases heating capacity. These watts are significant enough in most cases to increase EER and COP's fairly dramatically over ARI 320, 325, and 330 ratings. Fan Power Correction = (cfm x 0.472) x (esp x 249) / 300 Where 'cfm' is airflow in cfm and esp is the external static pressure at rated airflow in inches of water gauge. ISO Capacity and Efficiency Equations The following equations illustrate cooling calculations: ISO Cooling Capacity = Cooling Capacity (Btuh) + (Fan Power Correction (Watts) x 3.412) ISO EER Efficiency (W/W) = [ISO Cooling Capacity (Btuh) ÷ 3.412] / [Power Input (watts) ­ Fan Power Correction (watts) + Pump Power Correction (watt)] The following equations illustrate heating calculations: ISO Heating Capacity = Heating Capacity (Btuh) - (Fan Power Correction (Watts) x 3.412) ISO COP Efficiency (W/W) = [ISO Heating Capacity (Btuh) ÷ 3.412] / [Power Input (watts) - Fan Power Correction (watts) + Pump Power Correction (watt)] ARI 320 ISO WLHP ARI 325 ISO GWHP Cooling Entering Air -DB/WB °F 80/67 80.6/66.2 80/67 80.6/66.2 Entering Water -°F 85 86 50/70 59 Fluid Flow Rate Note 1 Note 2 Note 2 Note 2 Heating Entering Air -°F 70 68 70 68 Entering Water -°F 70 68 50/70 50 Fluid Flow Rate Note 1 Note 2 Note 2 Note 2 Note 1: Flow rate is set by 10°F rise in standard cooling test.

If the desired capacity cannot be achieved, select the next larger or smaller unit and repeat the procedure. Remember, when in doubt, undersize slightly for best performance. Example Equipment Selection For Cooling
Step 1 Load Determination: Assume we have determined that the appropriate cooling load at the desired dry bulb 80°F and wet bulb 64°F conditions is as follows: Total Cooling .......................................... 17,500 BTUH Sensible Cooling...................................... 15,500 BTUH Entering Air Temp ...... 80°F Dry Bulb / 64°F Wet Bulb Step 2 Design Conditions: Similarly, we have also obtained the following design parameters: Entering Water Temp ........................................... 90°F Water Flow (Based upon 10°F rise in temp.) ... 5 GPM Air Flow ........................................................590 CFM Step 3, 4 & 5 HP Selection: After making our preliminary selection (816020), we enter the tables at design water flow and water temperature and read Total Cooling, Sens. Cooling and Heat of Rej. capacities: Total Cooling ........................................... 18,300 BTUH Sensible Cooling...................................... 13,700 BTUH Heat of Rejection ..................................... 23,700 BTUH Step 6 & 7 Entering Air and Airflow Corrections: Next, we determine our correction factors. Table Ent Air Air Flow Selection Procedure
Step 1 Determine the actual heating and cooling loads at the desired dry bulb and wet bulb conditions. Step 2 Obtain the following design parameters: Entering water temperature, water flow rate in GPM, air flow in CFM, water flow pressure drop and design wet and dry bulb temperatures. Air flow CFM should be between 300 and 450 CFM per ton. Unit water pressure drop should be kept as close as possible to each other to make water balancing easier. Go to the appropriate tables and find the proper indicated water flow and water temperature. Step 3 Select a unit based on total and sensible cooling conditions. Select a unit which is closest to, but no larger than, the actual cooling load. Step 4 Enter tables at the design water flow and water temperature. Read the total and sensible cooling capacities (Note: interpolation is permissible, extrapolation is not). Step 5 Read the heating capacity. If it exceeds th
