Do not carry repair operations out on the air conditioning circuit in the open air during moist weather.

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 desiccant cartridge in the condenser and damages the entire system.

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

Install a new desiccant cartridge every time you open up the refrigeration circuit.

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.

Check drier cartridge packaging for damage. Dispose of drier cartridges with damaged packaging.

Install the desiccant cartridge 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.
