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.
Condenser Coil
Clean the condenser coil at least once a year,
more frequently in an outdoor environment
with high levels of pollution – including
automobile traffic, smog or soot, etc. This
procedure is critical to proper unit function
and longevity. Clogged or dirty condenser
coils will cause unit failure and may void any
warranty coverage for the unit refrigeration
system.
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.
Line Cord
Check unit line cord (power connection) for
any fraying or deterioration of the plug and
cord.
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.

Due to Ice Air’s ongoing product development programs, the information in this document is subject to change without notice.

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.
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 PTAC has permanently lubricated
motor bearings that do not require additional
lubrication. Blowers and motor 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.
Air Filter
1. Remove Permanent Air Filter from slides
at bottom of Cooling Chassis by sliding
the filter towards you.
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. On average, the filter should
be cleaned out every 6 months. However
this can vary with the presence of pets,
carpet, usage or air intake properties.
IMPORTANT: Do not operate unit without
filters.
Roomside Component Cleaning
IMPORTANT: In addition to the air filter, the
room side components can be cleaned with-
out removing the PTAC chassis from the wall
sleeve. The power cord MUST be disconnect-
ed from the electrical outlet 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 by
unplugging the line cord.
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.
