Evaporator Motor and Blower Assembly 

If there is evidence of dirt or dust build-up in 
the evaporator motor or blowers, they should 
be cleaned either by vacuum cleaning (if 
working in an apartment) or by removing the 
unit to a workshop location and cleaning with 
compressed air. 

p

!

  

 

WARNING:

 

Always obey safety 

guidelines for using compressed air 
in this latter case.

Your ICE AIR unit has permanently lubricated 
motor bearings that do not require additional 
lubrication. Blowers and motors are factory 
assembled for quiet performance – if there 
is any excessive noise and vibration from this 
assembly, it should be serviced by a qualified 
technician.

Condenser (Water Heat Exchanger)

Generally, if water flow exceeds 3 gpm per 
ton, the water velocities should keep your 
coil free of scaling of debris that could lead 
to erosion and fouling.

Air Filter

1.  Remove Permanent Air Filter.
2.  Wash Air Filter in warm water and 

biodegradable cleaner.

3.  Rinse with clean water and allow to dry 

completely.

4.  Replace Air Filter.
5.  As an alternate cleaning method, the 

filter may be cleaned on both sides using 
a vacuum cleaner and a soft brush type  
attachment.

IMPORTANT: 

Do not operate unit without 

filters.

Evaporator Coil

Check the coil for cleanliness and uniformity 
of fins. If the coil is dirty, vacuum clean with 
a soft brush attachment. This is the only form 
of cleaning that should be carried out within 
an apartment. If the coil requires additional 
cleaning, the unit must be removed and 
cleaned using compressed air and/or 
washed. These operations MUST be carried 
out in a facility properly equipped to handle 
this type of work in a safe and professional 
manner.

Roomside Component Cleaning

IMPORTANT: 

Power MUST be disconnected 

before carrying out any of the following 
cleaning!

To access the components within the chassis 
of the unit: 

1.  Unit must be in OFF Position.
2.  Disconnect unit from power source.
3.  Remove the unit front cover/access 

door by unscrewing the retaining screws 
that hold it in place. You will then have 
access to the unit components.

NOTE: Pictures of components and parts 
may vary depending on your model.
