WARNING
▪ When carrying out an inspection on the switch box of the unit, ALWAYS make
sure that the unit is disconnected from the mains. Turn off the respective circuit
breaker.
▪ When a safety device was activated, stop the unit and find out why the safety
device was activated before resetting it. NEVER shunt safety devices or change
their values to a value other than the factory default setting. If you are unable to
find the cause of the problem, call your dealer.
WARNING
Air purging heat emitters or collectors. Before you purge air from heat emitters or
collectors, check if or is displayed on the home screen of the user interface.
▪ If not, you can purge air immediately.
▪ If yes, make sure that the room where you want to purge air is sufficiently
ventilated. Reason: Refrigerant might leak into the water circuit, and
subsequently into the room when you purge air from the heat emitters or
collectors.

DANGER: RISK OF EXPLOSION
Pump down – Refrigerant leakage. If you want to pump down the system, and there
is a leak in the refrigerant circuit:
▪ Do NOT use the unit's automatic pump down function, with which you can collect
all refrigerant from the system into the outdoor unit. Possible consequence: Self-
combustion and explosion of the compressor because of air going into the
operating compressor.
▪ Use a separate recovery system so that the unit's compressor does NOT have to
operate.
