Sound power levels
Discharge
Measurement conditions:
Measurements taken in a room adjacent to the room containing the FWD, at the outlet of the rectangular duct (1.5 m
long) fixed to its discharge opening.

Refrigerant leak detector R454B
When a refrigerant leak of R454B is detected (concentration > 500 ppm) during a unit operation then the control
algorithm switches off immediately all compressors, an auxiliary heater, closes EEV, opens fresh air on 100 % and
keeps running outdoor, indoor fans and exhaust fans (if installed) at least for 10 min.
A corresponding alarm will be displayed on the service terminal.
It is not possible to reset the alarm during the 10 min of the ventilation, not possible to run the compressors or an
auxiliary heater during this period.
After 10 min left is possible to reset the alarm if the concentration < 500 ppm and to run the unit again. But it is
highly recommended to verify refrigeration circuit, to nd a refrigerant leak. In case of a leak the unit probably
cannot start again because of low refrigerant charge in the system. Do not forget to verify both refrigerant circuits
of Duplex units.
It is highly recommended to verify both refrigerant circuits, and to repair impacted refrigerant circuit, even if there is
the second refrigerant circuit (duplex unit) which should not be impacted.
When the unit is in OFF mode, and a refrigerant leak is detected, then only an alarm is displayed on the service
terminal, and no ventilation is running. Then it is necessary to verify physically the refrigerant circuit. It is not
possible to run the unit.
