Winterization
If the pump needs to be winterized, drain water from the pump as follows:
1.
Disconnect the power supply and wait at least 5 minutes for the VFD capacitors to
discharge. Before starting work, the LED "LINE" must be OFF. Make sure that the
power cannot be restored accidentally.
2.
Close the inlet and outlet shutoff valves and open the bypass valve if the system
has one.
3.
Disconnect all pipes from the pump.
4.
Remove the plug on the bottom of the pump and drain all water from the pump.
Replace the plug and store the pump in a cool dry place.
To return the pump to service, ensure the plug is in place before reconnecting the
pump to the system.
