6.8 Power failure
In order to avoid damage to the compressor, the refrigerant supply must be closed in the event of
power failure, e.g. by closing the magnetic valve. Safety measures elsewhere in the system will
prevent the pressure in the heat exchanger from exceeding the design pressure.
6.9 Fan motors connections
The maximum load of the motors and the recommended settings for the overload relays are to be
respected. The electrical control circuit should be arranged with a manual reset device in order to
prevent continuous on/off switching (tripping) of the motors. Suppliers and manufacturers of electri-
cal motors provide no guarantee for motors that are combusted through overload.
Ensure complete electrical isolation before performing any wiring.
