Tempstar TVA9 Owner's Manual V2

Our products are designed, tested and built in accordance with US Department of Energy standardized procedures and other standards; however, actual operating results and efficiencies may vary based on manufacturing and supplier tolerances, equipment configuration, operating conditions and installation practices. A Note about Safety Any time you see this symbol in manuals, instructions and on the unit, be aware of the potential for personal injury. There are three levels of precaution: DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies hazards that could result in personal injury or death. CAUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.

About your Air Conditioning System Your new cooling system is what we call a split system. It has an outdoor unit and an indoor unit connected to each other with copper tubing called refrigerant lines. Each of these units has a rating plate with the model and serial numbers you will need to reference when calling an authorized dealer about your system. Take a few moments now to locate those numbers and record them on your warranty included in this booklet. Using your New System Your new air conditioning system is controlled by an Ion Control or thermostat installed inside your home. See the Ion Control or thermostat Homeowner Guide for more details on system operation. Variable Speed Operation You may notice your system runs for longer periods of time. This system is designed to meet the cooling needs of the home at a wide range of conditions. Your indoor temperature will remain more consistent with fewer drafts, better humidity control, enhanced comfort and enhanced energy efficiency. Cooling your Home For cooling operation, make sure the System or Mode control is set to the appropriate mode. Then, adjust the Temperature control to your desired setting. Finally, use the Fan control to select AUTO or ON (runs continuously).

Operation under Extreme Conditions Your air conditioner will run as long as necessary to maintain the indoor temperature selected on your Ion Control or thermostat. On extremely hot days, your air conditioner will run for longer periods at a time than on moderate days. Your system will also run for longer periods of time under the following conditions: Frequent opening of exterior doors Operating laundry appliances Taking hot showers More than the usual number of people present in the home More than the normal number of electric lights in use Drapes or blinds are open on the sunny side of the home Sound Your new heat pump is different from most cooling systems. This is a variable speed system, designed to operate at different speeds depending on temperature and humidity conditions. You may notice the sound coming from the outdoor unit changing from time to time depending on weather conditions. The higher speed produces a higher sound. This change of speed allows the system to operate more efficiently and maintain comfortable conditions inside the home as the outdoor temperature rises. You may also hear a slight hissing sound at the outdoor unit. This is the sound of system pressure equalization which is required to enable soft and easy starting of the next cycle. These sounds are normal and do not represent a problem with your system. Routine Maintenance Simple, routine maintenance as described below will enhance your air conditioner systems ability to operate economically and dependably. Always remember the following safety precautions:

NOTE: There may be more than one electrical disconnect switch.

Keep Filter Clean A clogged or improperly installed air filter on your indoor unit will increase operating costs and shorten the life of the unit. For detailed filter cleaning information refer to indoor unit literature.

Do Not Block Floor, Wall or Ceiling Vents When drapes, furniture, toys or other common household items block vents, the restricted airflow lessens the systems efficiency and life span. Do Not Cover or Block Outdoor Unit The outdoor unit needs unrestricted airflow. Do not cover it or place items on or next to it. Do not allow grass clippings, leaves, or other debris to accumulate on the sides or top of the unit. Maintain 12 (305 mm) minimum clearance between the unit and tall grass, shrubs, etc. Check Condensate Drain Your air conditioner removes humidity from your home when cooling. After a few minutes, water should trickle from the condensate drain of the indoor coil. Check this occasionally to be sure the drain system is not clogged. Drainage will be limited if you live in a very dry environment. Do Not Operate Below Minimum Operating Temps in Cooling Mode Your outdoor unit is not designed to operate below the minimum temperatures shown below. The minimum depends on which control:

With Ion Control: 40F (4.4C) With Thermostat Control: 55F (13C)

System protections may not allow the unit to operate below these minimum temperatures. Base Pan Drainage Periodically check for and remove debris that has settled around the base of your outdoor unit. This will ensure proper drainage of the base pan and eliminate standing water inside the outdoor unit. Level Installation Your dealer will install the outdoor unit in a level position. If the support base settles or shifts and the unit is no longer level, be sure to re-level it promptly to assure proper drainage. If you notice water or ice collecting beneath the unit, arrange for it to be drained away from the unit.

Sea Coast Coil Maintenance Coastal locations require additional maintenance of the outdoor unit due to highly corrosive airborne ocean salt. Although your new system is made of galvanized metal and is protected by top-grade paint, we suggest washing all exposed surfaces and the outdoor coil about every 3 months. Consult your dealer for cleaning intervals and procedures or ask about a service contract for scheduled professional cleanings. Troubleshooting IMPORTANT: Before you request dealer service: Check the indoor and outdoor disconnect switches Also check your

main electrical panel circuit breakers or fuses. Turn circuit breaker off for at least 2 minutes, and turn back on. Check for sufficient airflow. Air filter(s) should be reasonably clean

and interior vents should be open and unobstructed. Check Ion Control or thermostat settings. For cooling, your desired

setting should be LOWER than the displayed room temperature, and the System/Mode control should be on COOL or AUTO.

Time delays - depending on the air conditioner you have, there may be delays in unit operation that are built-in to protect the equipment and your comfort. Dont be alarmed if you notice a time delay in operation. It may be a standard protection feature of your equipment. Check with your dealer for more information on time delays.

If you need to contact your dealer for troubleshooting and/or repairs, be sure to have the model and serial numbers of your equipment available (there are spaces on the cover for you to write this information). Regular Dealer Maintenance In addition to the routine maintenance you perform, your system should be inspected regularly by a properly trained service technician. Many dealers offer this service at a reduced rate with a service contract. Some service contracts may offer additional discounts and free services.

Table 1 Maintenance Checklist Monthly maintenance items and outdoor unit rinsing may be performed by the consumer. All other maintenance items and all service work must be performed by a qualified service technician. Read all Warning labels.

Notes: 1.) The above list may not include all maintenance items. Inspection intervals may vary depending on climate and operating hours. Consult your HVAC dealer about a service contract for seasonal inspections. 2.) Do not use harsh chemicals or high pressure water on coils. More frequent rinsing is required for units near a sea coast.
