RSHPC Heat Pump
ESEC Heat/Cool
GENERAL INFORMATION
The Applied Comfort PTHP/PTAC is designed and
built for through-the-wall installation in either new or
existing buildings. The self contained refrigerant
system delivers cooling. Resistance heaters provide the
heating. Additionally, the SHPC heat pump delivers
reverse cycle refrigerant heat when the outdoor
temperature is moderately cool.
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.
WARNING:
Potential fire risk – this unit is not
intended for use with a duct system.
FOR EFFICIENT OPERATION
Air Filter
IMPORTANT:
An improperly maintained air filter, or
not using a filter at all, will void the warranty.
Keep air intake filter clean. Units use a washable air
filter located in the filter bed in the bottom of the of the
wall sleeve and is true to the Original Equipment
Manufacturer’s size of 41.5” wide x 5.25” deep x 0.35”
thick. The filter is a wall sleeve component and is not
provided with the PTHP/PTAC chassis. If it is a
replacement situation and the original filter needs
replacing or is not even present, the filter is available to
order as Part No. ACCRSFILTER.
Washable air filters 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.
The filter holder as shown in the illustration below
is shipped with the chassis and must be used to
maintain the interlocking feature with the front
panel.
Proper use of the filter holder ensures that the
front panel must be removed in order to access the
filter. The front panel is removable by removing two
screws at the top of the panel. Be sure the filter bracket
flange is behind the front panel before reinstalling the
front panel.
IMPORTANT:
Always ensure the air filter is present
and properly secured in place. Always reinstall the air
filter, front panel, and the two screws as described
above. This will prevent unintended or unauthorized air
filter removal and ensure safe operation of 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:
