Protect air conditioning circuit and components from moisture when carrying out repair work - AH83.30-P-0005-01H

MODEL 240 

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

The function may be impaired in the event of ingressed moisture in the A/C system's refrigeration circuit.

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 fluid reservoir and damages the entire system.

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

The fluid reservoir must be replaced 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 the packaging and the fluid reservoir for signs of damage. Dispose of the new fluid reservoir if necessary.

Install the fluid reservoir no later than 20 minutes after opening 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.
