Operating Instrucitons
Air Filter Cleaning
The air filter should be checked at least twice a month to see if cleaning is necessary.
Trapped particles in the filter will build up and block the airflow. This reduces the cooling
capacity and can also cause an accumulation of frost on the cooling coils.
If the filter becomes torn or damaged you should replace it
immediately. Replacement filters are available from your
salesperson, dealer, and authorized customer service centers.
1. Open the inlet grille downward by grasping the top outside
edges of the inlet grille and pulling it towards you.
2. Remove the air filter from the front grille assembly by pulling
the air filter up slightly.
3. Wash the filter using lukewarm water and a mild detergent.
4. Gently shake all excess water from the filter.
Make sure the filter is completely dry and replace the filter
back into the unit.
