Protect air conditioning circuit and components from moisture when carrying out repair work

Moisture in the refrigerant circuit reduces the system's refrigeration output and leads to damage to the components. Acidification in the circuit caused by moisture decomposes the drier element installed (e.g. fluid reservoir, filter drier or desiccant cartridge) and thus damages the entire system.

After separating/unscrewing refrigerant lines, immediately seal off the connection openings so that they are airproof using suitable stop plugs (parts kit).

The drier element must be replaced every time the refrigeration circuit is opened.

Always store all spare components in a dry, sealed-off area. Do not remove stop plugs in new components until just before they are installed. Use special care when handling the fluid reservoir with its integral desiccant.

When a fluid reservoir is left open, the drier element quickly becomes saturated with moisture, rendering it useless.

Check drier element packaging for damage. Dispose of drier elements with damaged packaging.

Install the drier element no later than 20 minutes after opening the packaging.

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