Mounting: Check that the unit is properly mounted, to avoid abnormal noises and vibrations when starting up the unit.
Damaged equipment: Check the inside of the unit for damaged components or squeezed pipes.
Refrigerant leak: Check the inside of the unit for refrigerant leakage. If there is a refrigerant leak, call your local dealer.
Power supply voltage: Check the power supply voltage on the local supply panel. The voltage must correspond to the voltage on the
identification label of the unit.
Air purge valve: Make sure the air purge valve is open (at least 2 turns).
Shut-off valves: Make sure that the shut-off valves are fully open.

DANGER
If it's necessary to check the running status of the pump when unit power on, please do not touch the internal electronic control box components
to avoid electric shock.
Failure diagnosis at first installation
If nothing is displayed on the user interface, it is necessary to check for any of the following abnormalities before diagnosing possible
error codes.
- Disconnection or wiring error (between power supply and unit and between unit and user interface).
- The fuse on the PCB may be broken.
If the user interface shows "E8" or "E0" as an error code, there is a possibility that there is air in the system, or the water level in the
system is less than the required minimum.
If the error code E2 is displayed on the user interface, check the wiring between the user interface and unit.
More error code and failure causes can be found in 13.4 "Error codes".
