NAEC Heat/Cool
GENERAL INFORMATION
This Applied Comfort PTAC is designed and built for
through-the-wall installation in either new or existing
buildings. The self contained compressor and
refrigerant system delivers the cooling, and resistance
heaters provide the heating.
WARNING:
To avoid property damage, bodily injury
or death, ensure power is disconnected before any
service is attempted. Repairs should be made by
qualified service personnel only. The chassis must be
installed in accordance with the Authority Having
Jurisdiction, and all Local and National Codes,
including the National Electrical Code, and the
Canadian Electrical Code, as applicable.
FOR EFFICIENT OPERATION
Air Filter
Keep air intake filter clean. Units are provided with a
washable filter that can be cleaned with soap and
water. Inspect and clean the filter a least once a month
or more often as conditions dictate. Replace as
necessary. A dirty, clogged filter reduces the
efficiency of the system. It can also cause erratic
performance of controls and can result in damage to
the motor and compressor.
Operating the unit
without an air filter will void the warranty.
WARNING:
To avoid bodily injury, ensure power is
disconnected before removing the air filter, as there
will be potential exposure to rotating parts. Always
replace the air filter, filter bracket, and screw to close
off the bottom of the unit to prevent unintended contact
with the blower wheels, before operating the unit.
Clean Coils
As part of regular servicing, clean the condenser coil,
and evaporator coil at least annually, or more often as
dictated by the severity of the particulates and
pollutants circulating in the outdoor and indoor
operating environments. One suggested method is as
follows:
Unimpeded Outdoor Airflow
Do not block off the outside air flow to the unit. The
condenser air inlet and outlet must be free of
obstructions, and of any external influence that would
cause the hot discharged condenser air to be re-
circulated back into the condenser air intake. Outdoor
air is drawn into the condenser section via the air
intake on the right side of the rear grill. Hot condenser
air is strongly ejected out of the left portion of the rear
grill, thereby minimizing air re-circulation back into
the intake areas. Paper, leaves, dirt, or other material
blocking airflow, or fouling the condenser coil can
impair efficiency and cause serious damage to the
compressor.
