HSXA19 Air Conditioner
Congratulations! You have made a wise choice with the purchase of
your Lennox HSXA19 air conditioner with R410A refrigerant. Your
HSXA19 unit features two−stage operation and SilentComfortt
technology, making it both ultra−efficient and quiet. Lennox prides it-
self in manufacturing high quality products that keep you comfortable
and keep your monthly energy bills low, year after year.
Warranties
Your unit is covered by one of the best warranties in the industry. The
compressor in your new HSXA19 air conditioner is designed for use
with R410A refrigerant and is backed by a 10−year
limited warranty. All remaining components are
covered by a 5−year limited parts warranty. That’s
one more reason to trust Lennox.
Your Dave Lennox SignaturetCollection air conditioner includes a
sheet which outlines the warranty and its conditions. Keep your
warranty along with other important records
concerning the purchase and maintenance of your
heating and cooling equipment.
You should be aware that failure to maintain your sys-
tem as outlined in this manual will void your equipment warranty.
Maintenance
In order to ensure peak performance, your system must be properly
maintained. Clogged filters and blocked airflow prevent your unit from
operating at its most efficient level.
Ask your Lennox dealer to show you where your indoor unit’s filter is
located. It will be either at the indoor unit (installed internal or external
to the cabinet) or behind a return air grille in the wall or ceiling. Check
the filter monthly and clean or replace it as needed.
Disposable filters should be replaced with a filter of the same type
and size. If you are unsure about the filter you need for your system,
call your Lennox dealer for assistance.
Important!
Turn off electrical power to the unit at the disconnect switch
before performing any maintenance. The unit may have multiple
power supplies.

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.
DThe 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.)
DThe refrigerant lines should be visually
inspected and the coils should be checked for
leaks.
DWiring should be checked for loose
connections.
DVoltage must be checked at the indoor and
outdoor units (units operating).
DThe amp-draw at the outdoor fan motor and
indoor blower motor should be checked.
Values should be compared with those
given on unit nameplate.
DIndoor unit filters should be cleaned or
replaced.
DThe refrigerant charge should be checked
and system pressures should be gauged.
DThe condensate drain line should be
checked for free and unobstructed flow and
it should be cleaned, if necessary.

THERMOSTAT OPERATION −− COMFORT IS AT YOUR FINGERTIPS
System Switch
Set the system switch for heating, cooling or auto
operation. The auto mode allows the system to
automatically switch from heating mode to cooling
mode to maintain predetermined comfort settings.
Temperature Indicator
The temperature indicator displays the actual
room temperature.
Programmable Thermostats
Your Lennox system may be controlled by a
programmable thermostat. These thermostats
provide the added feature of programmable time-
of-day setpoints for both heating and cooling.
Refer to the user’s information manual provided
with your particular thermostat for operation
details.
Though your thermostat may vary somewhat from
the description below, its operation will be similar.
Temperature Setting Levers
Set the lever or dial to the desired temperature
setpoints for both heating and cooling. Avoid fre-
quent temperature adjustment; turning the unit off
and back on before pressures equalize puts
stress on the unit compressor.
Fan Switch
In AUTO or INT (intermittent) mode, the blower
operates only when the thermostat calls for heat-
ing or cooling. This mode is generally preferred
when humidity control is a priority. The ON or
CONT mode provides continuous indoor blower
operation, regardless of whether the compressor
or furnace is operating. This mode is required
when constant air circulation or filtering is desired.
