5. Maintenance

1) Cut off the power supply,

open the front panel and take off the electric box cover. Disconnect quick

connector of water pump power cable, and pull out the signal cable connected to the indoor control PCB.

Cut water supply to the unit, and drain out water in the monoblock unit away. Use a wrench to loosen the

connectors of water pump, and take the pump out from the unit.

Connect a new pump back to water system and electric system of the unit.
