REFRIGERANT CIRCUIT
The entire refrigerant circuit is a maintenance-free, hermetically sealed system and may only
be maintained or repaired by specialist companies for cooling and air conditioning.
CLEANING THE AIR FILTER
The air filters have to be cleaned, as soon as they are dirty, at least once a week.
Ensure that the air filters are neither worn nor damaged. The corners and edges of the air
filters must not be deformed or rounded. Before reinserting the air filters, make sure that they
are undamaged and dry.
1. Remove the air filters from the device.
2. Clean the filters using a slightly damp, soft, lint-free cloth. If the filters are heavily
contaminated, clean them with warm water mixed with a neutral cleaning agent.
3. Allow the filters to dry completely. Do not put any wet filters into the device.
4. Reinsert the air filters into the device.
