Protect
Your
Investment
Proper
Maintenance
is Your
Responsibility
Your system may be equipped
with an electronic air cleaner
which will provide respiratory
relief by removing up to 90
percent of all airborne particles
which pass through it. If it is,
ask your dealer to instruct you
on its maintenance.
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 applicable)
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.
Comfort is at
Your Fingertips
Though your thermostat may
vary somewhat from the
description below, its operation
will be similar.
Temperature Setting Levers
Set the indicator lever or dial to
the desired temperature setpoints
for both heating and cooling.
Fan Switch
In AUTO or INT mode, the
blower operates only when the
thermostat calls for heating 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 burners are
operating. This mode is required
when constant air circulation or
filtering is desired.
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 setpoints for both
heating and cooling. Refer to the
user’s information manual
provided with your particular
thermostat for operation details.
