Start−Up And Performance Checklist - Lennox 13ACX Installation Instructions Manual

S
Please contact your dealer to schedule proper
inspection and maintenance for your equipment.
S
Make sure no obstructions restrict airflow to the
outdoor unit.
S
Grass clippings, leaves, or shrubs crowding the unit
can cause the unit to work harder and use more
energy.
S
Keep shrubbery trimmed away from the unit and
periodically check for debris which collects around the
unit.
Routine 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.
1. Air Filter 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.
2. Disposable Filter
replaced with a filter of the same type and size.
NOTE If you are unsure about the filter required for your
system, call your Lennox dealer for assistance.
3. Reusable Filter
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.
