FILTER

ICE AIR WCACs are equipped with a washable/reusable 

Aluminum Filter.  It is recommended that you clean the indoor 

air filter after every 350 to 400 hours of unit operation – more 

frequently if the unit is running in an environment of high dust, 

pet dander or other pollutants in the indoor atmosphere. 

• Filter inspection: The filter is located at 

the bottom of your unit. To remove filter, 

slide it out towards you. 

• To reinstall, place filter under the unit  

and slide back into the filter rack.

FILTER CLEANING 

To clean your filter, use lukewarm water with a biodegradable 

cleaner. Rinse and allow to dry completely before reinstall-

ing in unit. (As an alternate cleaning method, the filter may 

be cleaned on both sides using a vacuum cleaner with a soft 

brush type attachment).

DO NOT OPERATE UNIT WITHOUT FILTER. 

This practice will damage and/or seriously impair  

the performance of your unit and could void your Warranty.

ROOMSIDE COMPONENT CLEANING

Evaporator Coil and Drain Pan / Drain Hoses

IMPORTANT NOTE:  The power MUST be disconnected to the 

unit before carrying out any of the following cleaning!

To access the components within the roomside section of 

the unit, disconnect the power to the unit and then remove 

the unit chassis front cover by unscrewing the #8 hex head 

retaining screws that hold the front cover in place (use a ¼” 

hex head driver). You will then have access to the following 

components: 

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 from the apartment 

and cleaned using compressed air and / or washed. 

These operations MUST be carried out in a facility prop-

erly equipped to handle this type of work in a safe and 

professional manner. 

DRAIN PAN / DRAIN HOSE CLEANING

The condensate pan is located directly under the  

evaporator coil. Check the visible section of the interior of 

the drain pan for any buildup of dirt or condensate water. 

Wash annually to remove all dirt build-up. Check 

condensate drain pan for algae growth every 2 to 3 

months.  If algae growth is apparent, consult a water 

treatment specialist for treatment. The application of 

algaecide every 2 to 3 months will typically eliminate 

algae problems. 

DRAIN HOSE

Check drain hose for leaks and blockage to eliminate 

potential problems.
