8. Troubleshooting
The water pump is fitted with the following safety
equipment:
8.1 High-pressure switch :
The high-pressure switch protects the heat pump from
excessive pressure in the cooling circuit. In the event of
any disturbances (excessive pressure), the high-pressure
switch will stop the pump. The system will restart when
the high-pressure switch is reset manually. Take off the
front cover by removing the screw.
Press the red button for RESET.
