The HC-AIR module is an essential accessory to be used when transferring hydrocarbon refrigerant and should be considered in the risk assessment process.
Good ventilation in the work area will ensure that any vapours resulting from a leak or release will disperse rapidly.
The fan module should be placed at floor level near the work area and can be connected up to 5 meters away.

It is recommended to turn on the fan before the refrigerant management begins.

Safety procedure for the work area where HC systems are maintained:
The area must be well ventilated
There must be no ignition source within 3m of the system
The area must be monitored with a hydrocarbon detector

Recommended procedure for maintenance of units with HC:
Connect the HC-Air RDA module 3m away from your working area and place it at floor level
Connect RDA HC-3 3m from the work area and recover the hydrocarbon refrigerant
When the low pressure light is illuminated, switch the unit to low pressure and let it run for 1 minute
Pressurize the system with nitrogen to just above atmospheric pressure.
Using an HC sensor, verify that there is no hydrocarbon coolant in the air before lighting the brazing torch.
Unsolder the connections and complete the service operation.
