PERSONAL

INJURY

AND

UNIT

DAMAGE

HAZARD

Failure to follow this warning could result in personal

injury, death or property damage.
Do not insert sticks, screwdrivers, or any other objects into

revolving fan blades.

!

WARNING

The fan must be kept free of all obstructions to ensure proper
cooling. Contact your dealer for any required service.

Electrical Controls and Wiring

Electrical controls are difficult to check without proper
instrumentation. If there are any discrepancies in the operating

cycle, contact your local dealer and request service.

Refrigerant Circuit

The refrigerant circuit is difficult to check for leaks without the
proper equipment. If inadequate cooling is suspected, contact your

local dealer for service.

EXPLOSION,

BURN AND ENVIRONMENTAL

HAZARD

Failure to follow this warning could result in personal

injury, death or property damage.
System under pressure. Relieve pressure and recover all

refrigerant before system repair or final unit disposal. Use

all service ports and open all flow--control devices,

including solenoid valves.

!

WARNING

Unit Panels

After performing any maintenance or service on the unit, be sure

all panels are fastened securely in place to prevent rain from
entering unit cabinet and to prevent disruption of the correct unit

airflow pattern.

Combustion Area and Vent System

For proper and safe operation, the furnace needs air for combustion

and ventilation. The air openings, on the furnace, the air openings

to the area in which the furnace is installed, and the spacing around
the furnace must not be blocked or obstructed.
The combustion area and vent system should be inspected visually
before each heating season. The normal accumulation of dirt, soot,

rust, and scale can result in loss of efficiency and improper

performance if allowed to build up. This inspection should be done
by a trained service person.

FIRE, EXPLOSION HAZARD

Failure to follow this warning could result in personal

injury, death and/or property damage.
If your unit makes an especially loud noise when the main

burners are ignited, shut down the heating section and call

your dealer.

!

WARNING

BURN HAZARD

Failure to follow this caution may result in personal injury.
Components in heating section may be hot after unit has

been started up. When observing flame, be careful not to get

close to or touch heating components.

!

CAUTION

Regular Dealer Maintenance

In addition to the type of routine maintenance you might be willing

to perform, your unit should be inspected regularly by a properly
trained service technician. An inspection (preferably each year, but

at least every other year) should include the following:

1. Inspection of all flue product passages--including the burn-

ers, heat exchanger, and flue collector box, Mare sure the
burner flames are blue in color and in proper adjustment.

Refer to Fig. 10 for burner flame.

2. Inspection of all combustion--and ventilation--air passages

and openings.

3. Close inspection of all gas pipes leading to and inside of

your unit.

4. Inspection and, if required, cleaning of the outdoor and

indoor coils.

5. Inspection and, if required, cleaning of the indoor coil con-

densate drain pan.

6. Inspection and cleaning of blower wheel housing and

motor.

7. Inspection of all supply--air and return--air ducts for leaks,

obstructions, and insulation integrity. Any problems found
should be resolved at this time.

8. Inspection of the unit base to ensure that no cracks, gaps,

etc., exist which may cause a hazardous condition.

9. Inspection of the unit casing for signs of deterioration.

10. Inspection of all electrical wiring and components to assure

proper connection.

11. Inspection for leaks in the refrigerant circuit. Pressure and

temperature check to determine appropriate refrigerant
charge.

12. Operational check of the unit to determine working

conditions. Repair or adjustment should be made at this

time.

Your servicing dealer may offer an economical service contract that

covers seasonal inspections. Ask for further details.
Complete service instructions can be found in the unit Installation,

Start--up and Service Instructions.

Warranty Certificate

Your unit has a limited warranty. Be sure to read the warranty
carefully to determine the coverage for your unit.
