SECTION IV: CARE OF SYSTEM

A periodic inspection, cleaning, lubrication, and adjustment of your heat

pump is available from your dealer. Be sure to ask him about this ser-

vice.

For those who prefer to do-it-yourself, follow the instructions below to

care for your system.

MOTOR LUBRICATION

The motors in these Air Handlers are permanently lubricated, and do

not require periodic oiling.

PERIODIC INSPECTION

Every time the filters are changed, the following items should be visu-

ally inspected:

• Check unit exterior to be sure it is in good condition and that there

are no obvious signs of deterioration.

• Check the drain lines to make sure there are no cracks, leaks or

blockages.

• Check the area around the unit and all registers and grilles – to

maintain good air flow.

Periodic inspection by a qualified service technician is highly recom-

mended.

Cleaning & maintenance of the Air Handler interior and its components

must only be done by a qualified service professional.

For more information, or if you have questions about the operation of

your Air Handler, Or if you suspect your unit is malfunctioning or in need

of service or repair

• Call a certified dealer or servicing contractor to check and/or

clean your Air Handler.

AIR FILTERS

Air filters maybe internally or externally mounted. Dirty filters greatly

restrict the flow of air and may cause damage to the moving parts. If the

filters become clogged the Electric Heaters and blower motor could

overheat resulting in a potentially dangerous situation. The filters

should be checked every month. On new construction, check the filters

every week for the first four weeks and every three weeks after that,

especially if the indoor fan is running continuously. When replacing the

filter(s) you must use filters that are the same size as those recom-

mended in Table 1. Never operate your Air Handler without a suitable

air filter.

Filter Care

Inspect the air filter every month. If dirty, wash reusable filters with a

mild detergent per manufacturer’s recommendations. Replace dispos-

able filters with new filters. Filters should be clean to assure maximum

efficiency and adequate air circulation. Drapes, furniture or other

obstructions blocking your supply and return air grilles will also

decrease efficiency.

An air filter was supplied by your dealer with you new Air Handler. A I”

filter rack compartment was built-in on your new Air Handler and may

use either a 1” disposable filter or a permanent washable filter media

per Table 1.

Removing Internally Mounted Air Filters

This Air Handler may have a filter located on bottom of the unit behind

the filter access panel.

1. Remove filter access panel by flipping the levers on each side of

the cabinet outward, to release the panel.

2. Install the clean filters with “air flow” arrow in the same direction as

the air flow in your duct.

3. Replace the panel and push levers in to secure the panel.

For Externally Mounted Air Filters

This air filter should be located in a rack attached to the casing of the

Air Handler or placed in the return air duct, or wall mounted filter grille.

Replace throw away filter(s) with the same size new filter(s).

Throw away filter(s) may be replaced with cleanable filter(s) at this time.

Cleanable filter(s) may be cleaned as described in the Manufacturer

instructions

How to Clean your Filter

Permanent type, washable, High-velocity filters may be cleaned with a

vacuum cleaner or taken away from the unit & washed with a garden

hose. Be sure to shake off excess water and allow filter to completely

dry before re-installing the filter.

CONDENSATE DRAIN LINES

Coils maybe included in the air handler or separately mounted. During

the cooling season check the condensate drain lines to be sure that

condensate is flowing from the primary drain but not from the secondary

drain. If condensate ever flows from the secondary drain the unit should

be promptly shut off and the condensate pan and drains cleaned by a

qualified service technician to insure a free flowing primary drain.

COIL CLEANING

If an inspection by a qualified service technician indicates the coil needs

to be cleaned, it should be washed with Calgon Coil Cleaner (mix one

part Coil Cleaner to seven parts water). Allow solution to remain on coil

for 30 minutes before rinsing with clean water. Solution should not be

permitted to come in contact with painted surfaces.

The owner/user should not attempt to disassemble the equipment nor

perform periodic maintenance unless they are experienced and quali-

fied to do so.

Blower & Coil access panels. Presenting risk of Personal Injury and/

or Fire or Electric Shock, potentially causing property damage, per-

sonal injury, and/or loss of life. The only owner serviceable part is the
