AH83.30-N-0005-01B Protect Air Conditioning Circuit And Components From Moisture When Carrying Out Repair Work


Never attempt to work on the air conditioner's refrigerant circuit in the open air under humid atmospheric conditions.

Moisture in the refrigerant circuit reduces the system's refrigeration output and leads to damage to the components. The formation of acid in the circuit which is caused by moisture decays the dehydrator in the fluid reservoir and damages the entire system.

After disconnecting or unscrewing refrigerant lines, immediately seal all connection apertures air tight with suitable plugs (part kit).

Replace fluid reservoir after each intervention in the dehydrator's refrigeration cycle.

Always store all spare components in a dry, sealed-off area. Do not remove plugs in new components until just before they are installed. Particular care should be paid here to the filter drier. A dehydrator that is not fully sealed becomes saturated after a brief period and thus unusable.

Further protection against moisture is provided by carefully evacuating the air conditioning system following repair operations. By generating suction within the system, the vacuum evacuation process removes any moisture that might have penetrated into the system during servicing.
