Proper maintenance (cont.)

Keep your air conditioner looking new for years.

Clean the enamel finish of your air conditioner with soap and water. For stubborn grease spots, use a household detergent. Do not use lacquer thinner or other synthetic solvents as they may damage the finish.

Call your dealer for additional routine maintenance

Your air conditioning system should be inspected regularly by a properly trained service technician. The inspection (preferably twice each year, but at least once a year) should include the following:

Routine inspection of air filter(s). Replacement or cleaning as required.

Inspection and cleaning of the blower wheel, housing, and motor as required.


Condensate drains should be checked and cleaned periodically to assure condensate can drain freely from coil to drain. If condensate cannot drain freely, water damage could occur.

Inspection and, if required, cleaning of indoor and outdoor coils.

Inspection of the indoor coil drain pan, plus the primary and secondary drain lines. If supplied, the auxiliary drain pan and line should be inspected at this time. Service should include cleaning, if required.

A check of all electrical wiring and connections.

A check for secure physical connec- tions of individual components within units.


Improper installation, adjustment, alteration, service, maintenance, or use can cause explosion, fire, electrical shock, or other conditions which may cause personal injury or property damage. Consult a qualified installer or service agency for information or assistance. The qualified installer or agency must use factory-authorized kits or accessories when modifying this product.

Operational check for the air condi- tioning system to determine actual working condition. Necessary repair and/or adjustment should be per- formed at this time.

Your servicing dealer may offer an economical service or preventative maintenance agreement that covers seasonal inspections. Ask your dealer for further details.

How to operate your system for peak performance

Setting the temperature

Place the system switch on COOL, and the fan switch on AUTO. Then set the temperature by using the indicator on the thermostat* control.

Now your system will cool your house whenever the indoor temperature climbs above the thermostat setting. It will shut off when the desired room temperature is reached.

In winter, it works the same way.

When the system switch is on HEAT, the system will operate whenever the room temperature falls below the temperature setting. Once the desired temperature is reached, the system will shut off.

Save energy with an electronic programmable thermostat.*

Program the thermostat for the temp- eratures that meet your comfort level. The Trane electronic programmable thermostat has up to four setup or setback periods each day, plus week- end and vacation programs.

*Accessory, purchased separately. Carefully read the accompanying thermostat manual for complete operating instructions.

Let the thermostat do its job.

Your system will perform most efficiently when you let the thermostat control it. Turning the system on and off manually is usually much less efficient. So let the thermostat do its job.

We recommend keeping the temper- ature setting at 78°F for cooling, 68°F for heating. However, you can select the temperature that meets your comfort level.

The point is, once you’ve set the thermostat, keep subsequent adjustments to a minimum.

When you’re going to be away from home for a few days, or when outdoor temperatures are moderate, don’t let the air conditioner run unnecessarily. Lower the thermostat to 55°F in the winter. And raise it to 85°F in summer. Then when you return, or when tempera- ture conditions dictate, you can reset the system and it will resume making your home comfortable again.

Never stop the system by shutting off the main power.

If the main power is ever disconnected for more than three hours, turn off the

thermostat. Then wait for at least three more hours after the power has been restored before turning the thermostat back on. Failure to follow this procedure could result in damage to your system.


If heating system is not operational during the cold weather months, provisions must be taken to prevent freeze-up of all water pipes and water receptacles. This is very important during times of vacancy.

How to help reduce summer humidity.

In summer, your air conditioner does more than cool the air — it helps remove the excess moisture, that can make the inside of your home feel muggy. When removing this moisture your system must work harder than when simply cooling the air.

That’s why kitchens, bathrooms and utility rooms should have vents and exhaust fans. These devices help prevent accumulation of moisture throughout the rest of the house so your air conditioner works less to keep you comfortable.
