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. And it’s automatically pro-

tected 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 AC or Heat

Pump system installed with this Air Handler. You may also have an

Electric Resistance Heater kit installed in this air handler.

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.

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.

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 a pro-

grammable electronic type thermostat.

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 computerized electronic 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 also features a digital clock.

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.

1060254-UUM-A-0713 SECTION IV: CARE OF SYSTEM The owner/user should not attempt to disassemble the equipment nor perform periodic maintenance unless they are experienced and qualified 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 service. For those who prefer to do-it-yourself, follow the instructions below to care for your system.

1060254-UUM-A-0713 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 vacuum cleaner. If the blower cannot be properly cleaned without removing it from the furnace, then this service must be performed by a qualified service agency.
