NOTE - If you are unsure about the filter required for
your system, call your Lennox dealer for assistance.
IMPORTANT
3, Reusable
Filter--Many
indoor units are equipped
with reusable foam filters, Clean foam filters with a
mild soap and water solution; rinse thoroughly; allow
filter to dry completely before returning it to the unit or
grille,
NOTE - The filter and all access panels must be in
place any time the unit is in operation,
4, Electronic
Air
Cleaner--Some
systems
are
equipped with an electronic air cleaner, designed to
remove airborne particles from the air passing through
the cleaner. If your system is so equipped, ask your
dealer for maintenance instructions.
5. Indoor
Unit--The
indoor unit's evaporator
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 location of
the drain line and how to check for obstructions. (This
would also apply to an auxiliary drain, if installed.)
IMPORTANT
6. Outdoor
Unit--Make
sure no obstructions
restrict
airflow to the outdoor unit. Leaves, trash or shrubs
crowding the unit cause the outdoor unit to work harder
and use more energy. Keep shrubbery trimmed away
from the unit and periodically check for debris which
collects around the unit.
When removing debris from around the unit, be aware
of metal edges on parts and screws, Although special
care has been taken to keep exposed edges to a
minimum, physical
contact with metal edges and
corners while applying excessive force or rapid motion
can result in personal injury,
Cleaning of the outdoor unit's coil should be performed
by a trained service technician. Contact your dealer
and set up a schedule (preferably twice a year, but at
least once a year) to inspect and service your air
conditioning or heat pump system,
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
furnace
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). An electronic 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 defrost cycle.
IN CASE OF EXTENDED POWER OUTAGE...
If the outdoor temperature is below 50°F (10°C) and power
to your outdoor unit has been interrupted for 6 hours or
longer, observe the following when restoring power to your
heat pump system.
•
Set the room thermostat selector to the "Emergency
Heat" setting to obtain temporary heat for a minimum
of 6 hours. This will allow system refrigerant pressures
and temperatures enough time to return to a stabilized
condition.
•
In Emergency
Heat mode, all heating demand
is
satisfied by auxiliary heat; heat pump operation
is
locked out. After a six-hour "warm-up"
period, the
thermostat can then be switched to the "Heat" setting
and normal heat pump operation may resume.
Though your thermostat
may vary somewhat from the
description below, its operation will be similar,
TEMPERATURE
SETTING LEVERS
Most
heat pump
thermostats
have two temperature
selector levers: one for heating and one for cooling. Set the
levers or dials to the desired temperature setpoints for both
heating
and
cooling.
Avoid
frequent
temperature
adjustment;
turning
the unit off and back on before
pressures equalize puts stress on the unit compressor.
