SAFTEY & OPERATION
FOR SAFE AND OPTIMAL ENJOYMENT OF YOUR ICE
AIR PTAC UNIT, PLEASE READ THE FOLLOWING
CONSUMER SAFETY AND OPERATING NOTES
CAREFULLY BEFORE OPERATING YOUR EQUIPMENT!
• This unit MUST be serviced only by professionally
trained, qualified technicians. Do NOT attempt to
maintain or service this unit on your own – severe
injury and death can occur from electric shock,
moving parts, and other hazards.
• Our ICE AIR units must each be wired on an
individual, dedicated electrical circuit with
the correct voltage and proper amperage
(capacity) to match the unit nameplate
requirements.
• Each unit’s electric circuit must have a proper
overcurrent protection device, employing an
approved circuit breaker or fuse of the proper
rating under NEMA and local building codes.
• Every unit contains refrigerant within a sealed and
pressurized refrigerant system. This system must
not be opened or tampered with and any refrigera-
tion system repairs MUST be carried out by trained
technicians. Refrigerant must be properly handled
and recycled per EPA regulations and guidelines.
Your ICE AIR unit must be properly installed and
commissioned to operate correctly. Improper unit
installation, adjustment or commissioning, and / or
improper heating system installation and connection
can lead to equipment malfunction and hazardous
operating conditions, and may void your warranty.

MAINTENANCE OVERVIEW
Your ICE AIR PTAC Unit is designed to provide you with
many years of efficient, trouble-free comfort condition-
ing service. To ensure equipment longevity and
efficiency, please make sure that the following simple
maintenance procedures are followed. This manual
assumes that your PTAC 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 pro-
cedures 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!
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.
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.
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.
Check and clean (if necessary) the unit evaporator coil
annually.
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 PTAC 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 PTAC 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 it’s ability to properly condition
the room.
FILTER CLEANING:
1. Unit must be in OFF Position.
2. Remove Enclosure (Cabinet) Front Cover
– as a safety precaution, disconnect unit from
power source by unplugging the line cord.
3. Remove Permanent Air Filter from slides at bottom
of Cooling Chassis, by sliding the filter towards you.
4. Wash Air Filter in warm water and biodegradable
cleaner.
5. Rinse with clean water and allow to dry completely.
6. Replace Air Filter.
7. (As an alternate cleaning method, the filter may
be cleaned on both sides using a vacuum
cleaner and a soft brush type attachment).
FILTER

11
OPERATING & MAINTENANCE MANUAL – PACKAGED TERMINAL AIR CONDITIONER (PTAC) – RSAN
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.
Drain Pan / Drain Hose Cleaning
Check the evaporator drain pan and hose assembly for
cleanliness by sliding the drain pan assembly towards
you, pulling it out approximately 1” – 1-1/2”. Check the
visible section of the interior of the drain pan for any
build-up of dirt or condensate water.
RSAN drain outlets located under the evaporator coil
can be checked for any blockages once the chassis front
cover is removed.
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.
ROOMSIDE COMPONENT CLEANING –
EVAPORATOR COIL AND DRAIN PAN / DRAIN HOSES
IMPORTANT NOTE: In addition to the air filter, the
roomside components can be cleaned without removing
the PTAC chassis from the wall sleeve. The power cord
MUST be disconnected from the electrical outlet before
carrying out any of the following cleaning!
To access the components within the roomside
section of the unit, disconnect the power cord
and then remove the unit chassis front cover by
unscrewing the 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
wall sleeve 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.
