12-6-1 Cleaning
There is no need for routine condenser cleaning in normal Home operating environments. If the environment is
particularly greasy or dusty, or there is significant pet traffic in the home, the condenser should be cleaned
every 2 to 3 months to ensure maximum efficiency.
If you need to clean the condenser:
● Remove the mechanical cover.
● Use a vacuum cleaner with a soft brush to clean the grille, the open areas behind the grille and the front
surface area of the condenser.
● Replace the mechanical cover.
