GMP4
INSTALLATION, OPERATION AND MAINTENANCE
The GMP can be used with heating or cooling systems. It is used to maintain the system
at a specific pressure. The GMP should be used to pressurize the system when it is at its
lowest temperature.

INSTALLATION INSTRUCTIONS

Do not install a pressure regulator or check valve between
system feeder and the system. Ensure that there is a system
isolation valve to isolate the system feeder.
Max pressure at 241.32 kPa (35 PSI)
Factory set at 82.5 kPa (12 PSI)
OPERATION VERIFICATION
It is important to check the proper functioning of each com­
ponent before final connection
1. Make sure the tank is free of dirt.

2. Check the operation of the pump. Connect the AC/DC
adaptor to the connection on the right side of the GMP4.
3. Check the operation of the pump/float assembly. Manually
lift the float to ensure free movement.
4. Check the overall operation of the unit.
A) Connect unit to system and close system isolation valve.
B) Plug the AC/DC adaptor to the wall outlet.
C) Fill tank with solution mix of glycol/water – up to 50% glycol
(we recommend a non­toxic propylene­based glycol).
D) Open unit by­pass valve (pump should start) to verify
that the pump works properly.
E) Close unit circulation valve and open system isolation valve.
SYSTEM START-UP
1. Install the system feeder on a levelled and sturdy surface,
or on provided wall mounting bracket.
2. Fill system feeder tank with correct fluid required
for system operation.
NOTE: The pressure gauge on system feeder may indicate a
different pressure than a gauge installed elsewhere in the
system. This difference may be due to calibration variations,
or elevation differences and is normal.
