System Shutdown
Set the thermostat system mode to OFF and the thermostat
fan mode to AUTO. See Figure 1.
NOTE:
The system will
not operate, regardless of the thermostat temperature
selector’s setting.
SYSTEm mAINTENANCE
CAUTION:
Verify all electrical power to the unit is shut off
before performing the following recommended
maintenance.
Proper maintenance is most important to achieve the best
performance from the appliance and should be performed
by a qualified service technician at least once a year.
Follow the maintenance schedule and the instructions
below for years of safe, trouble free operation.
• Do not place combustible materials on or against the
cabinet.
• Do not store gasoline or any other flammable vapors
and liquids in the vicinity of the unit.
• Annually inspect the physical support of the unit to
ensure that it is physically sound without sagging,
cracks, gaps, etc., around the base so as to provide a
seal between the support and the base.
• Annually inspect the return-air connection to ensure
that it is physically sound and is still sealed to the
casing of the unit. Also inspect the unit, ductwork, and
vent system for signs of physical deterioration.
• Always replace the doors on the unit after servicing.
Do not operate the unit without all doors and covers
in place. Avoid operating the unit when windows and
doors are open.
Regular Cleaning
CAUTION:
DO NOT touch any of the internal electrical
components while cleaning the unit.
• Remove any leaves and grass clippings from the
outdoor coil.
ImPORTANT: be careful not to damage
the aluminum fins
.
• Check for and remove any obstructions such as twigs,
sticks, etc.
•
Clean the blower compartment regularly during the
heating and cooling seasons to remove any dust
that may have accumulated in the compartment or on
the blower and motor. Buildup of dust on the blower
and motor can create excessive loads on the motor
resulting in higher than normal operating temperatures
and possible shortened service life.
Air Filters
WARNING:
Never operate the unit without a filter in the
return air system. Dust and lint in the return
air can build up on the internal components,
resulting in loss of efficiency, equipment
damage, and possible fire risk.
P6SP Series
units are factory equipped with pleated
2 inch disposable filters. The filters should be checked
periodically and replaced (or cleaned) when necessary
with filters of the same dimensional size. Replace using
disposable filters with a minimum airflow rating of
500 FPM or permanent filters only.
IMPORTANT NOTES:
•
The filter rack is field adjustable to accommodate
1” permanent filters. DO NOT use 1” disposable
filters in these units.
•
Always replace the filter access panels after
changing or cleaning the filters. DO NOT operate
unit without the filter access panels in place.
•
It is very important to replace or clean the filter(s)
installed in the return air duct of this system. A
clogged filter could cause airflow related problems
and reduce the overall efficiency of your unit.
Always replace disposable filter(s) installed in
your system only with the same size dimensional
filters that are being replaced.
•
Filters must be ULC approved or equivalent for
use in Canada.
motor Lubrication
The motors for the circulating air blower and outdoor fan
are pre-lubricated and sealed by the manufacturer. No
further oiling is required for the life of this product.
TROUbLESHOOTING
Before you call a Technician, check the following:
• Check the thermostat setting. Make sure the system
mode and temperature settings are correct.
• Check the electrical panel for tripped circuit breakers.
• Check the filters for dust accumulation.
• Check the unit and make sure it is clean and not
covered with grass or leaves.
• If the items above don’t resolve your problems, then
call your nearest service technician.
