Lenoxx Electronics HSXA19 - Manual (Page 3)

Many indoor units are equipped with re-usable
foam filters. These filters can be cleaned with a
mild soap and water solution. Rinse the filter
thoroughly and let it dry completely, before it is
returned to the unit or grille.
The filter and all access panels must be in
place any time the unit is in operation.
Your system may be equipped with one or
more of Lennox’ indoor air quality products,
which further ensure your total comfort. If so,
ask your dealer to instruct you on the mainte-
nance of these products.
Your indoor 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 where the main
condensate drain (and auxiliary drain, if appli-
cable) runs and how to check the drain for any
obstruction.
It is also
very
important to
provide
unrestricted
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 may have
collected around the unit.
Lennox Dealers
Nobody knows more about the care and
operation of your new Lennox equipment than
your Lennox dealer. Your Lennox dealer is
your best choice for routine maintenance or
service. When you call your Lennox dealer,
you can count on prompt, courteous and pro-
fessional service.
Before the start of each heating and cooling
season, the following service checks should
be performed by a qualified service
technician.
As always, electrical power to the unit
must be turned off prior to any unit
maintenance.
D The outdoor and indoor coils should be
inspected and cleaned. The outdoor coil
may be flushed with a water hose.
NOTE − It may be necessary to flush the
outdoor coil more frequently if it is exposed
to substances which are corrosive or which
block airflow across the coil (e.g., pet urine,
cottonwood seeds, etc.)
D The refrigerant lines should be visually
inspected and the coils should be checked for
leaks.
D Wiring should be checked for loose
connections.
D Voltage must be checked at the indoor and
outdoor units (units operating).
D The amp-draw at the outdoor fan motor and
indoor blower motor should be checked.
Values should be compared with those
given on unit nameplate.
D Indoor unit filters should be cleaned or
replaced.
D The refrigerant charge should be checked
and system pressures should be gauged.
D The condensate drain line should be
checked for free and unobstructed flow and
it should be cleaned, if necessary.
