Maintenance

Your ICE AIR unit is designed to provide 
many years of efficient, trouble-free comfort 
conditioning service. To ensure equipment 
longevity and efficiency, please make sure 
that the following simple maintenance 
procedures are followed. This manual 
assumes that your unit has been installed 
by a qualified installation professional, and 
is operating properly prior to maintenance 
service.

Have your unit periodically inspected by 
a properly trained service professional or 
building maintenance staff person. The unit 
should be checked for the safe and proper 
functioning of all of its systems at least 
once a year. The following recommended 
maintenance procedures should be carried 
out only by trained personnel with strict 
adherence to the Safety Guidelines outlined 
at the beginning of this manual. These 
procedures MUST be followed to ensure 
your safety and the safety of the person 
maintaining the equipment!

Indoor Air Filter

All units are equipped with a washable/
reusable 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. 

Condensate Drain Pan and Drain Hoses

Check the unit condensate drain pan and 
drain hoses annually to ensure proper 
condensate drainage. If any foreign matter 
build-up in the drain pan is found, clean the 
drain pan and drain hoses – frequency of 
cleaning depends on the level of dirt and 
pollutants that may be present in the indoor 
environment.

Evaporator Coil

Check and clean (if necessary) the unit 
evaporator coil annually.

Evaporator Motor and Blower Assembly 

Check and clean for dust and dirt build up as 
necessary. 

Compressor

Annual check should be performed to detect 
potential problems.

Condenser (Water Heat Exchanger)

Water coil maintenance is not required. If the 
unit installation is located in a system with 
water problem history, it is best to establish 
a periodic maintenance program. It is the 
building’s responsibility to maintain a water 
system that should provide your unit with 
treated and filtered water to keep water 
flowing freely through your equipment.

With these simple maintenance procedures 
carried out on a proper maintenance 
schedule, your unit should provide many 
years of trouble-free service. The procedures 
are covered in greater detail on the following 
pages and should be implemented by trained 
personnel. But there are certain items that 
you, the apartment owner or tenant, can do 
to ensure proper unit function:

•  Keep the area around your unit clear of 

objects that may block air flow into the 
unit – furniture, carpets and rugs, etc. 
may restrict air movement.

•  Keep the top of your cabinet free of 

objects that may block air flow out of the 
unit – plants, paperwork and books, etc. 
should not be placed on or above the 
discharge grille area.

•  Keep drapes, blinds and other window 

treatments clear of the air discharge 
area – any blockage of discharge air will 
have a negative impact on the unit and 
on its ability to properly condition the 
room.

General Unit Inspection

Visually inspect unit at least once a month. 
Pay special attention to hose assemblies and 
connections. Repair any leaks and replace 
deteriorated hose immediately to avoid 
potential costly damage to your property due 
to component failure.
