ROUTINE MAINTENANCE

ELECTRICAL SHOCK HAZARD!

WARNING

Turn off electrical power before service or

installation. All eletrical connections and wiring

MUST be installed by a qualied electrician

and conform to the National Code and all local

codes which have jurisdiction. Failure to do so

can result in property damage, personal injury

and/or death.

To ensure proper unit operation and life expectancy, the

following maintenance procedures should be performed

on a regular basis

1. Air Filter

To ensure proper unit operation, the air lters should

be cleaned at least monthly, and more frequently if

conditions warrant. The unit must be turned off before

the lters are cleaned.

To remove the air lters, grasp the top of the lter and lift

out of the front cabinet. Reverse the procedure to reinstall

the lters.

Clean the lters with a mild detergent in warm water, and

allow them to dry thoroughly before reinstalling.

2. Coils & Chassis

NOTE: Do not use a caustic coil cleaning agent on coils

or base pan. Use a biodegradable cleaning agent and

degreaser. The use of harsh cleaning materials may

lead to deterioration of the aluminum ns or the coil end

plates.

The indoor coil and outdoor coils and base pan should

be inspected periodically (annually or semi-annually)

and cleaned of all debris (lint, dirt, leaves, paper, etc.)

as necessary. Under extreme conditions, more frequent

cleaning may be required. Clean the coils and base

pan with a soft brush and compressed air or vacuum.

A pressure washer may also be used, however, you

must be careful not to bend the aluminum n pack. Use

a sweeping up and down motion in the direction of the

vertical aluminum n pack when pressure cleaning coils.

Note: It is extremely important to insure that none of the

electrical and/or electronic parts of the unit get wet. Be

sure to cover all electrical components to protect them

from water or spray.

3. Decorative Front

The decorative front and discharge air grille may be

cleaned with a mild soap or detergent. Do NOT use

solvents or hydrocarbon based cleaners such as

acetone, naphtha, gasoline, benzene, etc., to clean the

decorative front or air discharge grilles.

Use a damp (not wet) cloth when cleaning the control

area to prevent water from entering the unit, and possibly

damaging the electronic control

4. Fan Motor & Compressor

The fan motor & compressor and are permanently

lubricated, and require no additional lubrication.

5. Wall Sleeve

Inspect the inside of the wall sleeve and drain system

periodically (annually or semi-annually) and clean as

required. Under extreme conditions, more frequent

cleaning may be necessary. Clean both of these areas

with an antibacterial and antifungal cleaner. Rinse both

items thoroughly with water and ensure that the drain

outlets are operating properly.
