8 START-UP AND CONFIGURATION
The unit should be configured by the installer to match the installation environment (outdoor climate, installed options, etc.) and user
expertise.
CAUTION
It is important that all information in this chapter is read sequentially by the installer and that the system is configured as
applicable.
8.1 Initial Start-up At Low Outdoor Ambient Temperature
During initial start-up and when water temperature is low, it is important that the water is heated gradually.
8.2 Pre-operation Checks
Checks before initial start-up.
DANGER
Switch off the power supply before making any connections.
After the installation of the unit, check the following before switching on the circuit breaker:
• Field wiring: Make sure that the field wiring between the local supply panel and unit and valves (when applicable) have
been connected according to the wiring diagrams and to local laws and regulations.
• Fuses, circuit breakers, or protection devices Check that the fuses or the locally installed protection devices are of the size
and type specified in “TECHNICAL SPECIFICATIONS”.
• Make sure that no fuses or protection devices have been bypassed.
• Ground wiring: Make sure that the ground wires have been connected properly and that the ground terminals are
tightened.
• Internal wiring: Visually check the switch box for loose connections or damaged electrical components.
• 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.
• Shut-off valves: Make sure that the shut-off valves are fully open.
8.3 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 12 "Error codes".
