Outdoor Control Seven-Segment Display
and Push Button
Information concerning the outdoor control seven-seg-
ment display and push button operations are available on
the unit access panel and in the SL25XPV Installation and
Service Procedures manual.
System Component Configuration
(Outdoor Unit)
All configuration of the outdoor unit is completed using the
iComfort S30 thermostat. Please refer to the iComfort S30
Thermostat Installation and Setup Guide for complete de-
tails on how to integrate this unit into a communicating
system.
High Pressure Switch (S4)
This unit is equipped with a high pressure switch which is
located on the liquid line. The SPST, normally closed pres-
sure switch opens when liquid line pressure rises above
the factory setting of 590 ± 15 psig and automatically re-
sets at 418 ± 15 psig.
Homeowners Information
CAUTION
Before attempting to perform any service or maintenance,
turn the electrical power to unit OFF at disconnect switch.
In order to ensure peak performance, your system must
be properly maintained. Clogged filters and blocked air -
flow prevent your unit from operating at its most efficient
level. The system should be inspected and serviced be-
fore each cooling and heating season by a licensed pro-
fessional HVAC service technician (or equivalent).
Homeowner Maintenance
The following maintenance may be performed by the
homeowner.
• Contact a licensed professional HVAC technician to
schedule inspection and maintenance appointments for
your equipment before each heating and cooling season.
• Check the indoor unit filter each month and replace the
filter, if necessary.
• Have your Lennox dealer show you where your indoor
unit filter is located. It will be either at the indoor unit (in -
stalled internal or external to the cabinet) or behind a re-
turn air grille in the wall or ceiling. Check the filter month -
ly and clean or replace it as needed. Disposable filters
should be replaced with a filter of the same type and size.
• Check the indoor unit drain line for obstructions month-
ly. The indoor coil is equipped with a drain pan to collect
condensate formed as your system removes humidity
from the inside air. Have your dealer show you the loca-
tion of the drain line and how to check for obstructions.
(This would also apply to an auxiliary drain, if installed.)
• Check the area around the outdoor unit monthly and
remove any obstructions that may restrict airflow to the
outdoor unit. This would include grass clippings, leaves,
or papers that may have settled around the unit.
• Trim shrubbery away from the unit and periodically
check for debris which collects around the unit.
• During the winter months, keep the snow level below
the louvered panels.
NOTE -
The filter and all access panels must be in place
any time the unit is in operation. If you are unsure about
the filter required for your system, call your Lennox dealer
for assistance.
IMPORTANT
Sprinklers and soaker hoses should not be installed
where they could cause prolonged exposure to the
outdoor unit by treated water. Prolonged exposure
of the unit to treated water (i.e., sprinkler systems,
soakers, waste water, etc.) will corrode the surface of
the steel and aluminum parts, diminish performance
and affect longevity of the unit.
Thermostat Operation
See the thermostat homeowner manual for instructions on
how to operate your thermostat.
Heat Pump Operation
Your new Lennox heat pump has several characteristics
that you should be aware of:
• Heat pumps satisfy heating demand by delivering large
amounts of warm air into the living space. This is quite
different from gas- or oil-fired furnaces or an electric fur -
nace which deliver lower volumes of considerably hotter
air to heat the space.
• Do not be alarmed if you notice frost on the outdoor coil
in the winter months. Frost develops on the outdoor coil
during the heating cycle when temperatures are below
45°F (7°C). The heat pump control activates a defrost
cycle lasting 5 to 15 minutes at preset intervals to clear
the outdoor coil of the frost.
• During the defrost cycle, you may notice steam rising
from the outdoor unit. This is a normal occurrence. The
thermostat may engage auxiliary heat during the defrost
cycle to satisfy a heating demand; however, the unit will
return to normal operation at the conclusion of the de-
frost cycle.
Pre-Service Check
If your system fails to operate, check the following before
calling for service:
• Verify room thermostat settings are correct.
• Verify that all electrical disconnect switches are ON.
