Proper maintenance and cleaning of the supplied, 
washable air fi lter should prevent the evaporator 
from getting dirty. However, should the evaporator 
become dirty, it must be cleaned to maintain 
performance of the heat pump. Care should 
be taken during cleaning not to damage the 
evaporator fi ns. If the fi ns become bent, use a fi n 
straightening tool (12-fi ns per inch) to re-align the 
fi ns.

The most effective way to clean the evaporator 
is to use a commercially available spray cleaner 
intended for cleaning air conditioner evaporators. 
Select a product that is compatible with plastics 
such as ABS and high impact polystyrene and is 
a no rinse product intended for indoor use. Follow 
the procedure below for best results.

1.  Shut off power to the unit at the breaker or 

fuse box prior to servicing the unit.

2.  Remove the air inlet and outlet grills.

3.  Loosen and remove the four (4) nuts that 

mount the fan assembly to the fan shroud. 
Lower the fan assembly and carefully rest it 
in the area adjacent to the condensate pan. 
Cover the fan assembly to protect the motor 
from the evaporator cleaner.
Important: Do not damage the fan blades.

4.  Cleaner should be applied to the inlet (left) 

side of the evaporator only. Spray evaporator 
cleaner on the evaporator working from the 
top down. Do not over apply cleaner; use only 
enough to clean the evaporator.

5.  Clean the fan blades by carefully wiping each 

one with a damp cloth.

6.  Clean the condensate pan by wiping with a 

damp cloth to remove any dirt that may be 
present.

7.  Re-install the fan assembly and both side 

panels.
