Professional Maintenance
NOTICE !
Failure to follow instructions will cause damage to
the unit.
This unit is equipped with an aluminum coil.
Aluminum coils may be damaged by exposure to
solutions with a pH below 5 or above 9. The alumi-
num coil should be cleaned using potable water
at a moderate pressure (less than 50psi). If the
coil cannot be cleaned using water alone, Lennox
recommends use of a coil cleaner with a pH in the
range of 5 to 9. The coil must be rinsed thoroughly
after cleaning.
In coastal areas, the coil should be cleaned with
potable water several times per year to avoid corro-
sive buildup (salt).
Your heating and air conditioning system should be in-
spected and maintained twice each year (before the start
of the cooling and heating seasons) by a licensed profes-
sional HVAC technician. You can expect the technician to
check the following items. These checks may only be
conducted by a licensed professional HVAC techni-
cian.
Outdoor Unit
1 - Inspect component wiring for loose, worn or
damaged connections. Also check for any rubbing
or pinching of wires. Conrm proper voltage plus
amperage of outdoor unit.
2 - Check the cleanliness of outdoor fan and blade
condition (cracks) and clean or replace them, if
necessary.
3 - Inspect base pan drains for debris and clean as
necessary.
4 - Inspect the condition of refrigerant piping and
conrm that pipes are not rubbing copper-to-
copper. Also, check the condition of the insulation
on the refrigerant lines. Repair, correct, or replace
as necessary.
5 - Test capacitor. Replace as necessary.
6 - Inspect contactor contacts for pitting or burn marks.
Replace as necessary.
7 - Check outdoor fan motor for worn bearings/
bushings. Replace as necessary.
8 - Inspect and clean outdoor coils, if necessary and
note any damage to coils or signs of leakage.
Indoor Unit (Air Handler or Furnace)
1 - Inspect component wiring for loose, worn or
damaged connections. Conrm proper voltage plus
amperage of indoor unit.
2 - Inspect and clean or replace air lters in indoor unit.
3 - Check the cleanliness of indoor blower and clean
blower, if necessary.
4 - Inspect the indoor coil drain pans and condensate
drains for rust, debris, obstructions, leaks or cracks.
Pour water in pans to conrm proper drainage from
the pan through to the outlet of the pipe. Clean or
replace as necessary.
5 - Inspect and clean indoor coil, if necessary.
6 - Inspect the condition of the refrigerant lines and
conrm that pipes are not rubbing copper-to-
copper. Also, ensure that refrigerant pipes are not
being a󰀨ected by indoor air contamination. Check
condition of insulation on the refrigerant lines.
Repair, correct, or replace as necessary.
7 - Inspect the duct system for leaks or other problems.
Repair or replace as necessary.
8 - Check for bearing/bushing wear on indoor blower
motor. Replace as necessary.
9 - If your heat pump is matched with a gas- or oil-red
furnace for auxiliary heating, indoor unit service
will also include inspection and cleaning of the
burners, and a full inspection of the gas valve, heat
exchanger and ue (exhaust) system.
General System Test with System Operating
1 - Your technician should perform a general system
test. He will turn on the air conditioner to check
operating functions such as the startup and shuto󰀨
operation. He will also check for unusual noises or
odors, and measure indoor/outdoor temperatures
and system pressures as needed. He will check
the refrigerant charge per the charging sticker
information on the outdoor unit.
2 - Verify that system total static pressure and airow
settings are within specic operating parameters.
3 - Verify correct temperature drop across indoor coil.
