18. Maintenance & Cleaning
Always switch power supply off before starting any maintenance on the unit.
Wait for 5 minutes for electrical components to discharge.
The cooling unit is generally maintenance free and can be operated without filters in most environments.
If the ambient air is extremely dusty, we recommend installing filter mats (see accessories). These should be
cleaned or replaced at regular intervals. Oily or greasy filter mats should be replaced immediately. Do not use a
steam jet or high pressure to clean the filter mats. Do not wring out the filter mats.If the ambient air is
extremely oily, we recommend the use of metal filters (see accessories). They can be cleaned with standard
cleaning agents and reused. In addition the unit should have regular functional tests (approx. every 2,000 hours
depending on the grade of ambient pollution).
Note: The use of filter mats / metal filters reduces the cooling capacity of the unit..
Disposal
The cooling unit contains R134a refrigerant and small quantities of lubricating oil. Replacement, repairs and
final disposal must be done according to the regulations of each country for these substances.
