Lennox XC13: Maintenance

Dealer

Maintenance and service must be performed by a qualified installer or service agency. At the beginning of each cooling season, the system should be checked as follows:

Outdoor Unit

Outdoor unit fan motor is pre-lubricated and sealed. No further lubrication is needed.
Visually inspect all connecting lines, joints and coils for evidence of oil leaks.
Check all wiring for loose connections.
Check for correct voltage at unit (unit operating).
Check amp draw on outdoor fan motor.
Inspect drain holes in coil compartment base and clean if necessary.

NOTE ‐ If insufficient cooling occurs, the unit should be gauged and refrigerant charge should be checked.

Indoor Unit

Clean or change filters.
Lennox blower motors are pre-lubricated and permanently sealed. No more lubrication is needed.
Adjust blower speed for cooling. Measure the pressure drop over the coil to determine the correct blower CFM. Refer to the unit information service manual for pressure drop tables and procedure.
Belt Drive Blowers - Check belt for wear and proper tension.
Check all wiring for loose connections.
Check for correct voltage at unit. (blower operating)
Check amp draw on blower motor.

Indoor Coil

Clean coil if necessary.
Check connecting lines, joints and coil for evidence of oil leaks.
Check condensate line and clean if necessary.

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 outdoor unit. The following maintenance may be performed by the homeowner.

Outdoor Coil

The outdoor unit must be properly maintained to ensure its proper operation.

Please contact your dealer to schedule proper inspection and maintenance for your equipment.
Make sure no obstructions restrict airflow to the outdoor unit.
Grass clippings, leaves, or shrubs crowding the unit can cause the 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.

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.

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.

Disposable Filter – Disposable filters should be 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.

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.

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.

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.)
