Cooling Mode

With the SYSTEM or MODE control set to COOL, your unit will

run in cooling mode until the indoor temperature is lowered to the

level you have selected. On extremely hot days, your unit will run

for longer periods at a time and have shorter “off” periods than on

moderate days.

Gas Heating Mode

With the SYSTEM or MODE control set to HEAT, your unit will

run in heating mode until the room temperature is raised to the level

you have selected. Of course, your unit will run for longer periods

to maintain a comfortable environment on cooler days and nights

than on moderate ones.

Maintenance and Care for the Equipment Owner

Before proceeding with those things you might want to maintain

yourself, please carefully consider the following:

FIRE, EXPLOSION, ELECTRICAL SHOCK AND

CUT HAZARD

Failure to follow this warning could result in personal injury,

death or property damage.

1. TURN OFF ELECTRICAL POWER TO YOUR UNIT

BEFORE SERVICING OR PERFORMING

MAINTENANCE.

2. When removing access panels or performing maintenance

functions inside your unit, be aware of sharp sheet metal

parts and screws. Although special care is taken to reduce

sharp edges to a minimum, be extremely careful when

handling parts or reaching into the unit.

!WARNING

Air Filters

The air filter(s) should be checked every 3 or 4 weeks and changed

or cleaned whenever it becomes dirty. Dirty filters produce exces-

sive stress on the blower motor and can cause the motor to overheat

and shut down.

This unit must have air filters in place before it can be operated.

These filters can be located in one of at least two places. In many ap-

plications, the installer will provide return air filter grilles mounted

on the wall or ceiling of the conditioned structure. In the instance of

filter grilles, the filters can simply be removed from the grille and re-

placed.

The other typical application is an accessory filter rack installed in-

side the unit itself. The following information is given to assist in

changing filters used in these internal filter racks.

Table 1 indicates the correct filter size for your unit. Refer to Fig. 2

to access filters installed in the accessory filter rack.

Table 1—Air Filters Located Inside Unit

(For Replacement Purposes)

Unit Size Quantity Filter Size in. (mm)

A24---A30 212x20x1

(305x508x25)

A36---A60 312x24x1

(305x610x25)

To replace or inspect filters in accessory filter rack (See Fig. 2):

1. Remove the filter access panel using a 5/16--in. nut driver.

2. Remove the filter(s) by pulling it out of the unit. If the filter(s)

is dirty, clean or replace with a new one.

When installing the new filter(s), note the direction of the airflow

arrows on the filter frame.

If you have difficulty locating your air filter(s) or have questions

concerning proper filter maintenance, contact your dealer for in-

structions. When replacing filters, always use the same size and type

of filter that was supplied originally by the installer.

FIRE AND UNIT OPERATION HAZARD

Failure to follow this warning could result in personal injury,

death or property damage.

Never operate your unit without filters in place. An

accumulation of dust and lint on internal parts of your unit can

cause loss of efficiency.

Warranty Certificate

Your 577D unit has a limited warranty. Be sure to read the warranty

carefully to determine the coverage for your unit.

Before you call for service...

...check for several easily--solved problems.

If insufficient heating or cooling is suspected:

( ) Check for sufficient airflow. Check the air filter for dirt. Check

for blocked return--air or supply--air grilles. Be sure they are open

and unobstructed. If these checks do not reveal the cause, call your

servicing dealer.

If your unit is not operating at all, check the following list for

easy solutions:

( ) Check to be sure that the temperature specified by your UI isset

below the indoor temperature during the cooling season or above

the indoor temperature during heating season. Be sure the UI is set

to COOL or HEAT and not OFF.

( ) If your unit still fails to operate, call your servicing dealer for

troubleshooting and repairs. Specify the model and serial numbers

of your unit. (Record them in this manual in the space provided.) If

the dealer knows exactly which unit you have, he may be able to

offer suggestions over the phone, or save valuable time through

knowledgeable preparation for the service call.
