FWD 12 2
Refrigerant leak detector R454B is an option available only for R454B units. It is installed in the factory and set
3
according to the critical thresholds but it is not wired. 1
FWD 14 2
There are two relays available: Relay 1 for warning message and Relay 3 for critical message. When warning or
3
critical levels of R454B concentrations are reached, customer has to shutdown the electrical power to the unit.

FWD 20 2
It is needed to use a disconnect switch upstream from the unit, operated remotely, that will open electric circuit to
3
the unit when there is a refrigerant leakage. Please consult wiring diagrams regarding to the relay's connection. The
refrigerant detector is identified as 3A6.
