WARNING

TO PREVENT PERSONAL INJURY OR DEATH DUE TO IMPROPER INSTALLATION, ADJUSTMENT, ALTERATION, SERVICE OR MAINTENANCE, REFER TO THIS MANUAL. FOR ADDITIONAL ASSISTANCE OR INFORMATION, CONSULT A QUALIFIED INSTALLER, SERVICE AGENCY OR THE GAS SUPPLIER.

CAUTION

SHEET METAL PARTS, SCREWS, CLIPS AND SIMILAR ITEMS INHERENTLY HAVE SHARP EDGES, AND IT IS NECESSARY THAT THE INSTALLER AND SERVICE PERSONNEL EXERCISE CAUTION.

Preventive maintenance is the best way to avoid unneces- sary expense and inconvenience. Have this system inspected at regular intervals by qualified service personnel, at least twice a year. Routine maintenance should cover the follow- ing items:

1.Tighten all belts, set screws, and wire connections.

2.Clean evaporator and condenser coils mechanically or with cold water, if necessary. Usually any fouling is only matted on the entering air face of the coil and can be removed by brushing.

3.Lubricate motor bearings.

4.Align or replace belts as needed.

5.Replace filters as needed (see below).

6.Check for blockage of condensate drain.

7.Check power and control voltages.

8.Check running amperage.

9.Check operating temperatures and pressures.

10.Check and adjust temperature and pressure controls.

11.Check and adjust damper linkages.

12.Check operation of all safety controls.

13.Examine gas furnaces (see below and the User’s Information Manual).

14.Check condenser fans and tighten set screws.

FILTERS

CAUTION

TO PREVENT PROPERTY DAMAGE DUE TO FIRE AND LOSS OF EQUIPMENT EFFICIENCY OR EQUIPMENT DAMAGE DUE TO DUST AND LINT BUILD UP ON INTERNAL PARTS, NEVER OPERATE UNIT WITHOUT AN AIR FILTER INSTALLED IN THE RETURN AIR SYSTEM.

Every application may require a different frequency of replace- ment of dirty filters. Filters must be replaced at least every three (3) months during operating seasons.

Dirty filters are the most common cause of inadequate heat- ing or cooling performance. Filter inspection should be made at least every two months; more often if necessary because of local conditions and usage.

Dirty throwaway filters should be discarded and replaced with a new, clean filter.

Disposable return air filters are supplied with this unit. See the unit Specification Sheet or Technical Manual for the cor- rect size and part number. To remove the filters, remove the filter access panel on return side of the unit.

CABINET FINISH MAINTENANCE

Use a fine grade automotive wax on the cabinet finish to maintain the finish’s original high luster. This is especially important in installations with extended periods of direct sun- light.

CLEAN OUTSIDE COIL (QUALIFIED SERVICER ONLY)

The coil with the outside air flowing over it should be inspected annually and cleaned as frequently as necessary to keep the finned areas free of lint, hair and debris.

CONDENSER, EVAPORATOR, AND INDUCED DRAFT MOTORS

Bearings on the air circulating blower motor, condenser mo- tor and the combustion fan motor are permanently lubricated. No additional oiling is required.

FLAME SENSOR (QUALIFIED SERVICER ONLY)

A drop in the flame current can be caused by a nearly invis- ible coating on the flame sensor. This coating, created by the fuel or combustion air supply, can be removed by carefully cleaning the flame sensor with steel wool.

NOTE: After cleaning, the microamp signal should be stable and in the range of 4 - 6 microamps DC.

FLUE PASSAGES (QUALIFIED SERVICER ONLY)

At the start of each heating season, inspect and, if neces- sary, clean the unit flue passage.

LUBRICATION

The fan shaft bearings, the 1 to 2 HP supply fan motors the condenser fan motors and compressors are permanently lu- bricated.

INSPECTION & CLEANING

All flue product carrying areas of the furnace, its vent sys- tem, and main burners should be examined by a qualified service agency before the start of each heating season. This examination is necessary for continued safe operation. Par- ticular attention should be given to deterioration from corro- sion or other sources. This examination is accomplished in the following manner.

1.Disconnect power to the unit and remove furnace section access panel.

2.Remove burner assembly:

a.Disconnect the wires from the gas valve after noting which wires are connected to each terminal.
