That’s why attempts at “do-it-yourself” repairs on an in-warranty unit may void the remainder of your warranty. Other than performing the simple maintenance recommended in this manual, you should not attempt to make any adjustments to your heat pump system. Your dealer will be able to take care of any questions or problems you may have. Help ensure top efficiency by cleaning or replacing the filter monthly.* When the heat pump circulates and filters the air in your home, dust and dirt particles build up on the filter. Excessive accumulation can block the airflow, forcing the unit to work harder to maintain desired temperatures. And the harder your unit works, the more energy it uses. Clean or replace your filter twice a month during seasons when the unit runs more often. When replacing your filter(s), always use the same size and type that was originally supplied. Filters are available from your dealer. Where disposable filters are used, they must be replaced every month with the same size as originally supplied. How to remove your filter.* Ask your Trane dealer where the filter is located in your system and how to service it. Just be sure to replace it with the arrows pointing in the direction of the airflow. Efficiency can be maintained by keeping outdoor unit clear of snow, ice and debris. Efficient operation of your heat pump depends on the free flow of air over the coil. Anything that blocks the airflow, causes the compressor to work harder to move the warm air out of your house. Buildup of snow and ice can restrict airflow. As soon as possible after accumulation, clean snow from the area around the heat pump. To avoid overworking your unit, do not plant flowers or shrubbery right next to it. Also, make sure that nothing is stacked against the sides of the unit or draped over it. * Before removing the filter, see the owners manual furnished with the indoor unit. Proper maintenance for maximum efficiency ^! CAUTION To prevent injury, death, or property damage, read and follow all instructions and warnings, including labels shipped with or attached to unit before operating your new air conditioning system. ^! WARNING Disconnect all electrical power to the indoor air handler or furnace before removing access panels to perform any maintenance. Disconnect power to both the indoor and outdoor units. NOTE: There may be more than one electrical disconnect switch. Electric shock can cause personal injury or death. ^! CAUTION Although special care has been taken to minimize sharp edges in the construction of your unit, be extremely careful when handling parts or reaching into the unit. It heats in winter. It cools in summer. Proper maintenance (cont.) Making sure your outdoor unit is kept clear at all times helps it work at peak efficiency. Keep your heat pump looking new for years. Clean the enamel finish of your heat pump 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 heat pump 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. ^CAUTION! 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 cleaning of the blower wheel, housing, and motor as required. • 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 connections of individual components within units. ^WARNING! 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 heat pump system to determine actual working condition. Necessary repair and/or adjustment should be performed 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.
