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 qualifi ed 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 fl ammable 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 fi ns.
• 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 fi lter 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 fi re risk.
P6SP Series units are factory equipped with pleated
2 inch disposable fi lters. The fi lters should be checked
periodically and replaced (or cleaned) when necessary
with fi lters of the same dimensional size. Replace using
disposable fi lters with a minimum airfl ow rating of
500 FPM or permanent fi lters only.
IMPORTANT NOTES:
• The fi lter rack is fi eld adjustable to accommodate
1” permanent fi lters. DO NOT use 1” disposable
fi lters in these units.
• Always replace the fi lter access panels after
changing or cleaning the fi lters. DO NOT operate
unit without the fi lter access panels in place.
• It is very important to replace or clean the fi lter(s)
installed in the return air duct of this system. A
clogged fi lter could cause airfl ow related problems
and reduce the overall effi ciency of your unit.
Always replace disposable fi lter(s) installed in
your system only with the same size dimensional
fi lters 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 fi lters 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.
