When liquid line temperature drops below 50°F the thermostat closes energizing HR1. The thermostat will open, de−energizing HR1 once liquid line temperature reaches 70°F .

Liquid Line Filter Drier

A filter drier is factory-installed as illustrated in Unit Dimensions on page 2, with each XC14 unit to ensure a clean, moisture−free system. A replacement filter drier is available from Lennox. Refer to Lennox Repair Part Program.

IMPORTANT

Some scroll compressor have internal vacuum protector that will unload scrolls when suction pressure goes below 20 psig. A hissing sound will be heard when the compressor is running unloaded. Protector will reset when low pressure in system is raised above 40 psig. DO NOT REPLACE COMPRESSOR.

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

1.Clean and inspect the outdoor coil. The coil may be flushed with a water hose. Ensure the power is turned off before you clean the coil.

2.Outdoor fan motor is prelubricated and sealed. No further lubrication is needed.

3.Visually inspect connecting lines and coils for evidence of oil leaks.

4.Check wiring for loose connections.

5.Check for correct voltage at the unit (with the unit operating).

6.Check amp−draw outdoor fan motor.

NOTE − If owner reports insufficient cooling, the unit should be gauged and refrigerant charge checked.

Outdoor Coil

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, fertilizers, fluids that may contain high levels of corrosive chemicals such as salts)

SOutdoor Coil door coil may be flushed with a water hose.

SOutdoor Coil (Sea Coast) air in ocean

locations can carry salt, which is corrosive to most metal. Units that are located near the ocean require frequent inspections and maintenance. These inspections will determine the necessary need to wash the unit including the outdoor coil. Consult your installing contractor for proper intervals/procedures for your geographic area or service contract.

INDOOR UNIT

1.Clean or change filters.

2.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.

3.Check blower drive belt for wear and proper tension.

4.Check all wiring for loose connections

5.Check for correct voltage at unit (blower operating).

6.Check amp−draw on blower motor.

INDOOR COIL

1.Clean coil, if necessary.

2.Check connecting lines and coils for signs of oil leaks.

3.Check condensate line and clean, if necessary.

HOMEOWNER

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.

IMPORTANT

Sprinklers and soaker hoses should not be installed where they could cause prolonged exposure to the outdoor unit by treated water. Prolonged exposure of the unit to treated water (i.e., sprinkler systems, soakers, waste water, etc.) will corrode the surface of steel and aluminum parts and diminish performance and longevity of the unit.

Outdoor Coil

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

SPlease contact your dealer to schedule proper inspection and maintenance for your equipment.

SMake sure no obstructions restrict airflow to the outdoor unit.

SGrass clippings, leaves, or shrubs crowding the unit can cause the unit to work harder and use more energy.

SKeep shrubbery trimmed away from the unit and periodically check for debris which collects around the unit.

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.

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.
