WARNING

• This high efficiency Air Handling system has been precision engi-neered, manufactured of high quality materials, and passed many rigor-ous tests and inspections to ensure years of satisfactory service. That’s why you can rely on efficient, trouble-free operation. Your system is fully automatic. Set the thermostat and forget it. It’s automatically protected from damage by voltage fluctuations or excessive heating or cooling demands. Your air handler is actually two units – the indoor air blower and the indoor refrigeration coil, part of the outdoor air conditioning or heat pump system installed with this air handler. You may have an Elec-tric Resistance Heater kit installed in this air handler.
• FIRE OR ELECTRICAL HAZARD Failure to follow the safety warnings exactly could result in serious injury, death or property damage. A fire or electrical hazard may result causing property damage, per-sonal injury or loss of life.

SECTION I: HOW YOUR AIR HANDLER WORKS

If your hand is wet and you blow on it, it feels cool because some of the moisture is evaporating and becoming a vapor. This process requires heat. The heat is being taken from your hand, so your hand feels cool. That’s what happens with a heat pump. During the cooling cycle, your system will remove heat and humidity from your home and will transfer this heat to the outdoor air. During the heating cycle, your system will remove heat and humidity from the outdoor air and will transfer this heat to your home. This is possible because even 0°F outdoor air contains a great deal of heat. Remember that your heat pump doesn’t generate much heat, it merely transfers it from one place to another.

CAUTION

• An air handler should never be operated without a suitable air filter. Dirty filters greatly restrict the flow of air and may cause damage to the moving parts. The filters should be checked every month. On new construction, the filters must be checked every week for the first four weeks and after that every three weeks. When replacing the fil-ter(s) you must use filters that are the same size as those recom-mended.

SECTION II: SYSTEM OPERATION
Your thermostat puts full control of the comfort level in your home at your fingertips. DO NOT switch your thermostat rapidly “On” and “Off” or between “Heat” to “Cool” This could damage your equipment. Always allow at least 5 minutes between changes. It is not recommended to close or block off supply or return air grills. Damage to equipment and higher utility bills may result.

SETTING THE THERMOSTAT
Although thermostats may vary widely in appearance, they are all designed to perform the same basic function: to control the operation of your air conditioning or heat pump system. Regardless of size or shape, each thermostat will feature a temperature indicator; a dial, arm, or push button for selection of the desired temperature; a fan switch to choose the indoor fan operation; and a comfort switch for you to select the system mode of operation. Only approved thermostats have been tested and are fully compatible with this equipment. Please be aware that many different thermostats operate on batteries or “power stealing” principals. These types of ther-mostats can not be supported as trouble free when used with this product

A complete operating instruction is provided by the manufacturer for each thermostat. Familiarize yourself with its proper operation to obtain the maximum comfort with minimum energy consumption. If your system has been designed to allow both cooling and heating operation, you may have either a manual change-over type, or an auto-matic change-over type. Manual change-over simply means that the comfort switch must be manually positioned every time you wish to switch from the cooling to heating or heating to cooling modes of operation. The automatic change-over thermostat is actually a sophisticated elec-tronic version of a manual change-over type. This thermostat includes features which allow “set-back” temperature variations for periods of sleep, or while you are away during the day, and means energy savings for you. The thermostat may feature a digital clock and outdoor tem-perature.

Fan Operation Selection
A multi-position fan switch allows you to choose the type of fan opera-tion of the indoor fan.
AUTO – With the thermostat fan switch set to “AUTO”, the fan will run intermittently as required for either heating or cooling. This position will provide the lowest operating cost. If you purchased one of our thermo-stats, it may have an Intelligent fan mode which continually circulates the air during occupied modes or when you are at home, and can cycle the fan during unoccupied mode or during the night while you sleep to further conserve energy.
ON – If the fan switch is set to “ON”, the indoor fan will not shut off. How-ever, the system will still operate as required by room temperatures. This provides continuous air filtering and more even temperature distri-bution throughout the house, which is especially useful in homes with basements. Usually during spring and fall, when neither heating nor cooling is required, you may want to run only the fan to ventilate, circulate, and fil-ter the air in your home or building. Set the comfort control switch to “OFF” and the fan switch to “ON”. Be sure to return the switches to their original positions for normal operation.

Heating Cycle
With the thermostat in the heating position, and the outdoor tempera-ture in the range of 20 to 30° or below, the outdoor unit may run 100%of the time. Some systems can be equipped with balance point control to provide even more efficient operation. This control will prevent the electric heater from being energized when the outdoor air is above some prede-termined temperature setting (0 to 45°F). At higher temperatures, a heat pump may provide all the heat the home will ever need. At lower temperatures, the auxiliary heat will be energized to keep your home comfortable. When the outdoor air is cool and moist, frost may form on the surface of your outdoor heat pump coil. When this frost builds to a certain point, your system will switch to a defrost cycle. Although you may feel cooler air coming from your registers, DO NOT adjust your thermostat. The frost will melt quickly, and your system will return to normal operation automatically.

Cooling Cycle
Switch your thermostat to cool. Select a comfortable thermostat tem-perature setting, typically between 75 and 80°. Comfort sensations vary with individuals. The lower the indoor temperature desired, the greater will be the number of hours your unit must operate. Set your thermostat 2 or 3°F below normal several hours before enter-taining large groups during hot weather. People give off considerable heat and moisture. On an extremely hot day, the indoor temperature may rise 3 to 6°F above the thermostat setting. Properly selected equipment does not have the capacity to maintain a constant indoor temperature during the peak load. Over-sizing your system to handle this peak load is not prac-tical because the oversized system would operate much less efficiently at all other conditions.

MANUAL CHANGE-OVER THERMOSTAT

COOLING YOUR HOME:
With the comfort control switch in the “COOL” position, the system will operate as follows: When the indoor temperature rises above the level indicated by the temperature adjust-ment setting, the system will start. The outdoor unit will operate and the indoor fan will circulate cool, filtered air. When the room temperature is lowered to the setting selected, the system will shut off.

HEATING YOUR HOME:
If your system includes a heating unit and the comfort control switch is in the “HEAT” position, the system will operate as follows: When the indoor temperature drops below the level indi-cated by the temperature adjustment setting, the system will start. The heating system will operate and the indoor fan will circulate warm, fil-tered air. When the room temperature rises to the setting selected, the system will shut off. Whether heating or cooling, the fan will continue to operate if the fan switch was set in the “ON” position. The “AUTO” setting will allow the fan to shut off when your thermostat reaches your desired setting.

ELECTRONIC THERMOSTAT
The computerized electronic thermostat, when programmed, will func-tion automatically to operate the system as follows: When the indoor temperature rises above the higher (COOL) setting, the outdoor unit will operate and the indoor fan will circulate cool, filtered air. When the room temperature is lowered to the selected level, the system will shut off. When the indoor temperature drops below the lower (HEAT) setting, the heating system will operate, and the indoor fan will circulate the warm, filtered air. When the indoor temperature rises to the selected setting, the system will shut off. The indoor fan will either shut off or run continu-ously, depending upon your choice of fan switch setting.

SECTION III: TO MAXIMIZE OPERATING EFFICIENCY

HEATING CONSERVATION
For the most efficient operation, keep storm windows and doors closed all year long. They not only help insulate against heat and cold, but they also keep out dirt, pollen, and noise.
Closing drapes at night, keeping fireplace dampers closed when not in use, and running exhaust fans only when necessary will help you to retain the air you have already paid to heat.
Keep lamps, televisions, or other heat producing sources away from the thermostat. The thermostat will sense this extra heat and will not be able to maintain the inside temperature to the desired comfort level.

COOLING CONSERVATION
To comfortably cool your home, your air conditioner must remove both heat and humidity. Don’t turn your system off even though you will be away all day. On a hot day, your system may have to operate between 8 to 12 hours to reduce the temperature in your home to a normal comfort level. Keep windows closed after sundown. While the outdoor temperature at night may be lower than indoors, the air is generally loaded with mois-ture which is soaked up by furniture, carpets, and fabrics. This moisture must be removed when you restart your system. The hotter the outside temperature, the greater the load on your sys- tem. Therefore do not be alarmed when your system continues to run after the sun has set on a hot day. Heat is stored in your outside walls and attic during the day and will continue to flow into your home for sev-eral hours after sunset.
Use your kitchen exhaust fan when cooking. One surface burner on “HIGH” requires one ton (12,000 BTUs) of cooling. Turn on your bath-room exhaust fan while showering to remove humidity. However, exhaust fans should not be run excessively. It would decrease effi-ciency by removing conditioned air.
You can help your system in the summer by closing drapes or blinds and by lowering awnings on windows that get direct sunlight.

SECTION IV: CARE OF SYSTEM

IMPORTANT
The owner/user should not attempt to disassemble the equipment nor perform periodic maintenance unless they are experienced and quali-fied to do so. A periodic inspection, cleaning, lubrication, and adjustment of your heat pump is available from your dealer. Be sure to ask him about this ser-vice. It is recommended that your heating and air conditioning system is inspected on a yearly basis by a licensed and qualified service provider. The service technician should clean coils, inspect and tighten all electri-cal connections, clean drain lines, and check for proper system opera-tion. For those who prefer to do-it-yourself, follow the instructions below to care for your system.

MOTOR LUBRICATION
The motors in these Air Handlers are permanently lubricated, and do not require periodic oiling.

PERIODIC INSPECTION

WARNING
Electric Shock and Moving Parts Hazards are present behind the Blower & Coil access panels. Risk of Personal Injury and/or Fire or Electric Shock, potentially causing property damage, personal injury, and/or loss of life. The only owner serviceable part is the filter behind the filter access panel Every time the filters are changed, the following items should be visu-ally inspected:

• Check unit exterior to be sure it is in good condition and that there are no obvious signs of deterioration.

• Check the drain lines to make sure there are no cracks, leaks or blockages.

• Check the area around the unit and all registers and grilles – to maintain good air flow.
  Periodic inspection by a qualified service technician is highly recom-mended. Cleaning & maintenance of the Air Handler interior and its components must only be done by a qualified service professional. For more information, or if you have questions about the operation of your Air Handler, Or if you suspect your unit is malfunctioning or in need of service or repair

• Call a certified dealer or servicing contractor to check and/or clean your Air Handler.

AIR FILTERS

Air filters maybe internally or externally mounted. Dirty filters greatly restrict the flow of air and may cause damage to the moving parts. Some pleated filters may be too restrictive and should not be used. If the filters become clogged the Electric Heaters and blower motor could overheat resulting in a potentially dangerous situation. The filters should be checked every month. On new construction, check the filters every week for the first four weeks and every three weeks after that, especially if the indoor fan is running continuously. When replacing the filter(s) you must use filters that are the same size as those recom-mended in Table 1. Never operate your Air Handler without a suitable air filter.
Filter Care
Inspect the air filter every month. If dirty, wash reusable filters with water. Replace disposable filters with new filters. Filters should be clean to assure maximum efficiency and adequate air circulation. Drapes, fur-niture or other obstructions blocking your supply and return air grilles will also decrease efficiency. An air filter was supplied by your dealer with your new Air Handler. A 1” filter rack compartment was built-in on your new Air Handler and may use either a 1” disposable filter or a permanent washable filter media per Table 1.

Removing Internally Mounted Air Filters
This Air Handler may have a filter located on bottom of the unit behind the filter access panel.

1. Remove filter access panel by removing screws from each side of the filter access panel.
2. Install the clean filter with “air flow” arrow in the same direction as the air flow in your duct. If air flow direction is indicated on the filter, refer to Figure 1.
3. Replace the panel, and reinstall screws to secure the panel.

For Externally Mounted Air Filters
This air filter should be located in a rack attached to the casing of the Air Handler or placed in the return air duct, or wall mounted filter grille(s). Replace throw away filter(s) with the same size new filter(s). Throw away filter(s) may be replaced with cleanable filter(s) at this time. Cleanable filter(s) may be cleaned as described in the Manufacturer instructions

How to Clean your Filter
Permanent type, washable, High-velocity filters may be cleaned with a vacuum cleaner or taken away from the unit & washed with a garden hose. Be sure to shake off excess water and allow filter to completely dry before re-installing the filter.

CONDENSATE DRAIN LINES

Coils maybe included in the air handler or separately mounted. During the cooling season check the condensate drain lines to be sure that condensate is flowing from the primary drain but not from the secondary drain. If condensate ever flows from the secondary drain the unit should be promptly shut off and the condensate pan and drains cleaned by a qualified service technician to insure a free flowing primary drain.

COIL CLEANING
If an inspection by a qualified service technician indicates the coil needs to be cleaned, it can be washed with water.

BLOWER CARE
Even with good filters properly in place, blower wheels and motors will become dust laden after long months of operation. The entire blower assembly should be inspected annually. If the motor and wheel are heavily coated with dust, they can be brushed and cleaned with a vac-uum cleaner. If the blower cannot be properly cleaned without removing it from the air handler, then this service must be performed by a quali-fied service agency.

WARNING
Make sure you DO NOT move the clip on weight on the indoor fan wheel when cleaning the wheel. This weight is used to balance the wheel. Moving the weight will cause the fan wheel to vibrate.
