technician, with the information needed to install,
start up, clean, maintain and service this ice
system.
The FM2400RH (remote high side) is the freezer
portion of a commercial ice machine. It is designed
to be connected to the condensing section of a
refrigeration system, specifically a supermarket
R-502 system. It consists of two evaporators, two
gearmotors, two liquid line valves, two control
boxes, two thermostatic expansion valves, and an
EPR valve.

Page 1 FOR THE INSTALLER: Specifications
The FM2400RH is designed to fit the Scotsman
storage bins BH800 or B90. Leg kit KLP4 is
recommended when using both the B90 bin and
an extension.
Installation Limitations: The FM2400RH is
designed for indoor installations only. The machine
must also be in a controlled environment where
the air temperature does not fall below 50
0
F., or
go above 100
0
F.
The water temperature must be between 40
0
F.
and 100
0
F.
The electrical power supply must not drop below
-5% of the lowest nameplate voltage or go above
10% of the highest nameplate voltage.

Page 2 FOR THE INSTALLER
Select the Location:
The unit can only be installed indoors
within the limitations described on
page 2.
The ice machine will have to be
connected to the buildings R502
refrigeration system, check to be
sure that the system has enough
extra capacity to handle a minimum
of additional 16,000 BTUs per hour
@ 110

temperature).
Storage Bin:
Scotsmans B90 will be the
presumed bin of choice. If using the
bin extension BX87, install heavy
duty leg kit KLP4 and place the bin
into position.
Remove the paper tape from the bin
edge gasket, and install the bin
extension onto the B90.
Remove the paper tape from the bin
extension top edge, and using a
mechanical lift, install the FM2400RH
onto the top of the storage bin
assembly.
Fasten the ice machine to the bin
using (4) 5/15-18 2.5" cap screws.
Level the assembly by:
a. Turning the leg levelers in or out
on the standard legs.
b. Use shims under the heavy duty
legs of the KLP4.
Locate the Nameplate: The
nameplate is located on the back
panel of the machine, and contains
the electrical characteristics
particular to the unit being installed.
Refrigeration Installation:
The skills of a refrigeration technician are required
to connect the ice machine to the buildings
refrigeration system.
////////////////////////////CAUTION/////////////////////////////
The FM2400RH-32B comes with a dry nitrogen
holding charge. Purge and evacuate before
connecting to a refrigeration system.
////////////////////////////////////////////////////////////////////////
Local Codes must be observed.
A P-trap should be installed where there will be
more than 10 of vertical rise in the suction line.

Page 3 Electrical Connections:
Locate the nameplate for the current requirements,
and then determine the wire size and type per the
National Electric Code. The machine requires a
solid chassis to earth ground wire.
Refer to the wiring diagram. The ice
machine should be connected to its
own electrical circuit, and be
individually fused.
Voltage, when the unit is under full
load, must remain within the limitations
listed on page 2.
LOW VOLTAGE CAN CAUSE
EQUIPMENT MALFUNCTION
AND/OR DAMAGE
All external wiring should conform to
the National, State, and local electrical
codes. Usually the services of a
licensed electrician will be required.

CONFORM TO ALL APPLICABLE CODES
Water Supply:
The recommended water supply line is 3/8" O.D.
copper tubing, with a minimum operation pressure
of 20 PSIG, and a maximum of 120 PSIG.
Connect to cold water using the male flare
connection at the back of the machine. Install a
shut off valve in an accessible space between the
ice maker and the water supply.
Drain System:
All drains are of the gravity type, and must have a
minimum of 1/4" fall per foot of horizontal run. The
drains must be installed to conform to local
plumbing codes. The use of a vent at the machine
and at the bin will allow the system to drain
properly. Use only rigid tubing for drains; insulation
of the bin drain is recommended.

Page 6 INITIAL START UP
1. Remove the top and front panels.
2. Open the water valve, and observe that the two
float reservoirs fill up with water and shut off.
3. Switch on the electrical power.
4. Open the hand valves (in the liquid lines).
5. Open the ball valves (in the suction lines).
6. Switch on one master switch, and observe:
The liquid line valve opens
The gearmotor runs
Within a short time, that side of the machine
begins to make ice.
Water flows from the water reservoir, and the
float
drops, letting in more water.
7. Switch on the other master switch, observe that:
