* Pressure code which is the standard factory setting. Other settings available upon request. 4.0 LOCATION AND ENVIRONMENT
A
lthough the control box is NEMA 4X, the gear pump motor is an open motor and comes with a
NEMA 15R power cord. Wingert Glycol Feed Systems should be installed indoors in a dry, covered
location and should not be exposed to direct weather conditions. Do not store outdoors.
5.0 INSTALLATION
MOUNTING
1) Utilizing the four 25/64 bolt holes located at the base of each vertical support leg, firmly secure
the Glycol Feed System to a level concrete pad. Be sure that the pad thickness complies with
local codes.
2) Install the Glycol Feed System within 10 feet of injection point into the system or pump
performance will vary.
PLUMBING
1) Install an isolation ball or gate valve at the discharge point(s) of the glycol feed system.
2) Plumb the discharge(s) 3/4 MNPT port to your system(s). This should be no more than 10 feet
in distance and have no more than one right angle (otherwise pump performance may vary).
WIRING
1) Wingert Glycol Feed Systems are supplied with a 14 gauge, 115 VAC power cord. Plug the
Glycol Feed System into a 115 VAC, 15 amp minimum receptacle (dual systems require 30
amps).
HARDWIRING
(See detail below)
1) Install a power disconnect box on the wall.
2) Connect power from disconnect box to glycol feed system, be sure that all wiring complies
with local codes.
3) Wire control panel power to the first three terminals on control starting from the left side.
#1 green = ground, #2 white = neutral (5 volts to ground), #3 black = hot (110 V to ground)
4) OPTIONAL - wire remote low level indicator to the last two terminals of the terminal block
from the left side.
#1 green = ground, #11 white = neutral (5 volts to ground), #12 orange = hot (110 V to ground)

FACTORY STANDARD SETTINGS
(See page 7 for parts locations)
1) Pressure relief valve(s): Maximum pressure switch setting
2) Pressure switch(es): Cut-in set to minimum and pressure differential set to maximum
HOW TO ADJUST THE PRESSURE RELIEF VALVE
1) Brass Pressure Relief Valve(s): Turning the adjustment handle counterclockwise will
decrease the relief pressure.
2) PVC Pressure Relief Valve(s); Turning the tamper resistant insert (with a pair of needle nose
pliers or adjustment wrench) counterclockwise will decrease the relief pressure.
HOW TO ADJUST THE PRESSURE SWITCH (SQUARE D MODELS)
1) Turning the large keep nut (cut-in adjuster #4) clockwise will increase the pressure switch cut-
in setting.
2) Turning the small keep nut (pressure differential #5) counterclockwise will decrease the
pressure differential setting.

Maintenance and care will depend upon the usage and environment in which the glycol feed
system is subjected to. The following is the suggested regular maintenance required to keep the
glycol feed system operating properly.
TANK AND PLUMBING
Routine Maintenance:
Periodic checking of the piping and tubing is required to insure proper
discharge of the glycol solution. The Y-strainer and check valve should be periodically checked
for clogging and wear.
GEAR PUMP
Routine Maintenance:
The pump should be checked for proper operation. If any pump/motor
noises, leaks or changes in operation are detected, the pump should be removed and examined
by a certified technician. Gear pump repairs can be difficult and should only be attempted by
qualified personnel. Improper repairs or assembly can result in pump failure and nullification of
the warranty.
Lubrication:
Carbon bearing motors do not require lubrication, however sleeve bearing motors
do. Follow the lubrication instructions that are provided on the motor label. If there are no
instructions, lubricate once a year with 10 to 15 drops of SAE 20 weight non-detergent or electric
motor oil. Do not over lubricate.

8.0 ADJUSTING FOR PRESSURE REQUIREMENTS
(See page 7 for parts locations, repeat steps 2 thru 10 for dual systems)
1) Isolate the glycol feed system from the makeup line by use of an isolation valve.
2) Remove pressure switch cover. Be sure to keep objects from interfering with the closing or
moving parts in the pressure switch.
3) Turn the glycol feed system power on and ensure that the glycol tank is full.
4) Turn the pump selec
