Flow Switch for Garden PAC GP01 A Pool Heat Pump - Part No. 040060620000 images
This flow switch is the replacement part with part number 040060620000 for the Garden PAC GP01 A pool heat pump.
The switch’s vane is installed in the water circuit.
It detects the flow of filtered water through the heat pump.
If there is insufficient water flow, the flow switch shuts off the heating to protect the heat exchanger and the compressor.
When the flow switch is faulty, the heat pump shuts down due to a flow fault, even if the filtration system is running.
The flow switch comes with its connecting cable.
It is an exact replacement for the original part in the Garden PAC GP01 A heat pump.
In a pool heat pump, the flow switch continuously monitors whether water is circulating through the heat exchanger.
When the water flow is sufficient, it allows heating to proceed.
When filtration stops or the flow drops too low, it opens its contact and the heat pump switches to safety mode.
This safety feature prevents the refrigeration circuit from running without water.
Without this protection, the heat exchanger could be damaged.
Turn off the power to the heat pump.
Stop the filtration system.
Close the heat pump’s water inlet and outlet valves.
Unplug the old flow switch, then unscrew it.
Install the new flow switch, making sure the water flows in the correct direction.
Connect the cable according to the wiring diagram in the heat pump’s manual.
Reopen the valves, check for leaks, then turn the heat pump back on.
ℹ️ Good to know: Before ordering, note the exact model number from your heat pump’s nameplate.
This part is compatible with the Garden PAC GP01 A model.
⭐ Tip from the team: Before replacing the flow switch, make sure the filter is clean, the bypass valves are open, and the filter pump is running.
Insufficient water flow causes the same flow error.
If in doubt, contact a qualified professional.
