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.
