Proper Care of Your System

CAUTION: Prior to any of the following maintenance proce- dures, shut off all power to the unit.

LUBRICATION

The indoor blower motor, outdoor fan motor and ventor motor are perma- nently lubricated and require no main- tenance.

GENERAL MAINTENANCE

The manufacture recommends that the furnace system be in- spected once a year by a qualified service person.

For proper and safe operation, the gas heating section needs air for com- bustion and ventilation. Do not block or obstruct air openings on the unit, nor the spacing around the unit. Keep the gas heating system area clear and free of combustible materials, gasoline and other flammable vapors and liquids.

Snow or debris should not be al- lowed to accumulate in or around the unit. Do not permit overhanging structures or shrubs to obstruct con- denser air discharge or vent outlet on your unit. These provide air for combustion and ventilation.

FILTER CARE

Single phase units are shipped without a filter and is the responsi- bility of the installer to secure a filter in the return air ductwork or install a Filter/Frame Kit (1FF0110).

A filter rack and a high velocity filters are standard on three phase units.

Filters must always be used and must be kept clean. When filters be- come dirt laden, insufficient air will be delivered by the blower, decreasing your units efficiency and increasing operating costs and wear-and-tear on the unit and controls.

Filters should be checked monthly especially since this unit is used for both heating and cooling.

REGISTERS

Supply air and return air registers must be open when the unit is in operation. Furniture must not block airflow in or out of the registers.

COIL CARE

An annual check and cleaning, if necessary, of the condenser coil should be done. Clean any debris and dirt from the outside coil face with a brush being careful not to damage the fins. If extremely dirty, a hose can be used to wash the coil from the inside out while brushing a soapy solution on the outside.

TROUBLESHOOTING

BEFORE CALLING A SERVICEMAN:

A.Check thermostat setting and insure thermostat is calling for heat or cooling.

B.Check thermostat for lint, dust, etc.

C.Check fuses or circuit breakers.

D.Check filters for excessive dust accumulation and/or restriction.

PARTS INFORMATION

UPG renewal parts may be ob- tained from your local qualified UPG contractor-check the yellow pages in your telephone directory.

SOME EFFICIENCY DO’S AND DON’TS

DON’T heat or cool unused areas. Reduce supply and return air flow to a minimum in areas which are not living spaces (storage rooms, ga- raged, basements, etc.).

DON’T be a "thermostat jiggler". Moving your thermostat setting will not make your system heat or cool any faster. Adjust your thermostat to a comfortable setting and leave it there.

DON’T restrict air circulation. Plac- ing furniture, rugs, etc. in such a way that they interfere with air vents will make your system work harder to achieve a comfortable temperature level. This requires more energy, which means greater cost to you.

DON’T heat or cool when you are away. If you are going to be away for a day or more, re-adjust your thermo- stat accordingly. Your furniture is far less demanding than you are when it comes to comfort levels. However, don’t expect the system to restore comfort conditions immediately upon returning home. It will take a little time.

DON’T locate lamps or other heat- producing appliances (radios, TV’s, heaters, etc.) near your thermostat. The heat from these items will give your thermostat "false information" about the temperature in the room.

DO select a comfortable thermo- stat setting, but keep in mind that moderation in temperature selection will save energy.

DO turn on your kitchen exhaust fan when cooking and your bathroom ex- haust fan when showering. Also, make sure your clothes dryer is properly vented. If these items are neglected, an excess heat and humidity condition may be created, causing your air con- ditioning system to run longer.

DO set your thermostat a few de- grees lower than normal several hours before entertaining a large group of people in a relatively small area. Peo- ple give off a considerable amount of heat and moisture in a closed area.

DO keep drapes and Venetian blinds closed when practical. These items provide insulation against heat loss/gain.

DO contact a qualified service man to make repairs or adjustments to your system. He has been trained to perform this service.
