Manual
8. Operation
Electrical shock hazard.
Turning The Unit Off
Turn OFF electric power supply at disconnect switch or ser-
vice panel before removing any access or service panel from
unit.
Failure to follow this warning can result in property damage,
personal injury, and/or death.
Scroll Anti-Cycle Timer (Where Applicable)
Single phase units with scroll compressors can be equipped with
an anti-cycle device which delays the start of the compressor in
the event of a power interruption. This equalizes pressure
throughout the system and prevents possible reverse rotation of
the scroll compressor.
CAUTION
Do NOT operate unit on cooling when the outdoor tempera-
ture is below 60°F. This is necessary to prevent possible
damage to the compressor.
1. Set the thermostat selector switch to OFF and set the fan
switch to AUTO. To restart, set thermostat selector switch to
COOL or HEAT and set thermostat to temperature desired.
2. To shut the unit down completely, turn electric high voltage
power OFF.
Thermostat Fan Switch Operation
With the thermostat fan switch in the ON position, the circulating
air blower will run. With the thermostat fan switch in the AUTO
position, the circulating air blower will only run during each cooling
or heating cycle.
Adjusting Room Temperatures
If the temperature in individual rooms is not as desired, balance
the system by adjusting the dampers in the branch ducts. Adjust a
little at a time and wait a day after each change to judge the effect.
Once the dampers are adjusted for normal weather conditions, it
is best to leave them that way. Compensate for temporary weath-
er changes by adjusting the thermostat setting.
9. Maintenance
Monthly Maintenance and Inspection
Checks
Annual Maintenance and Inspection
Air Filters
CAUTION
Do NOT operate unit without air filters.
Inspect filters at least monthly and replace or clean as required.
Washable filters may be cleaned by soaking in mild detergent and
rinsing with cold water. Replace filters with the arrows on the side
pointing in the direction of air flow. Dirty filters are the most com-
mon cause of inadequate heating or cooling performance, and of
compressor failures.
Cooling Season Checks (Monthly)
Electrical shock hazard.
Turn OFF electric power supply at disconnect switch or service
panel before removing any access or service panel from unit.
Failure to follow this warning can result in property damage,
personal injury, and/or death.
The annual inspection MUST include lubrication and cleaning as
required to ensure efficient operation of the unit. To simplify ac-
cess, remove all access panels.
Condenser Fan Motor
Condenser Coil CAUTION
Keep the condenser inlet and outlet area clean and free of leaves,
grass clippings or other debris. Grass should be kept short in front
of the condenser air inlet. Shrubbery MUST be trimmed back so it
is no closer than 30 inches (762mm) to unit panels and 10 inches
(254mm) to coil inlet.
The condenser and evaporator coils should be cleaned by using a
non-acid type cleaner to avoid removing paint or other type of
coating on the coil. Always turn off electrical power to the unit dur-
ing service and maintenance.
Condensate Drain
Periodic cleaning of the condensate drain & trap may be required.
Inspect drainage of condensate after at least 15 minutes of con-
tinuous operation in cooling mode during humid conditions.
Do NOT use 3 in 1 oil, penetrating oil, WD40 or similar oils to
oil motor bearings.
Motors used in this product are considered permanently lubri-
cated for up to 5 years. If oil ports are provided on the motor, oil
the condenser fan motor and evaporator blower motor after five
years of operation and every five years thereafter.
Use SAE 10W30 motor oil. To oil, remove the hole plugs from the
motor end bells and add several drops of oil with a squeeze type,
flexible tube oiler. Replace hole plugs after oiling. Do NOT over
oil.
Clean the surrounding area and the condenser and evaporator
coils. Use caution to avoid damage to coi! fins. Use a non-acid
type of cleaner ONLY.
