This is not required for restart, since the settings have been saved (settings remain
saved even in case of power failure).

bled by service personnel, see
After completing installation and wiring and tubing of indoor and outdoor units,
check for refrigerant leaks, loose power supply or control wiring, wrong polarity,
and ensure that no single phase in the power supply is disconnected.

This heat pump is equipped with an efficient electronic control system. All neces-
sary settings and options are described in the operating manual of the controller.
Tip: The correct use of the controller saves money. Particularly the correct settings
of flow temperature, hot water temperature, heating curve and heating times can
result in substantial cost savings.
After finishing operation, wait at least five minutes before turning main power
switch off. Otherwise, there is a risk of water leak or unit failure.
Procedure:
Switch OFF the main switch of the heat pump.
Turn OFF the circuit breakers: Compressor, control voltage and electrical heating
element.
