WARNING
• Incorrect handling of the thermostat, safety valve or other valves
may lead to tank rupture or plate heat exchanger damage. When
servicing the unit follow the instructions carefully:
– Always turn off the main power supply when the water
supply is being shut off.
– Test the free operation of the safety valve regularly by
opening the valve ensuring the water flows freely.
– Electrical connection and all servicing of the electrical
components should only be carried out by an authorized
electrician.
– Fitting and all servicing of plumbing fixtures should only be
carried out by an authorized installer.
– When replacing the thermostat, safety valve, or any other
valve or part supplied with this unit, use only approved
parts of the same specification.
Testing operations
1 Check the power supply between the outdoor unit and the
auxiliary circuit breaker.
• 1 phase power supply: L, N
• 3 phases power supply: R, S, T, N
2 Check the control panel.
• Check that you have connected the power and
communication cables correctly. (If the power cable
and communication cables one mixed up or connected
incorrectly, the PCB will be damaged.)
• Check the temp. sensor, drain pump/hose, and display are
connected correctly.
3 Press K1 or K2 on the outdoor unit PCB to run the test mode
