We recommend that the user read all sections of this

manual and keep the manual for future reference.

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.

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.

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.

WARNING

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.

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.

1190827-UUM-B-0818 If your system has been designed to allow both cooling and heating operation, you may have either a manual change-over type, or an automatic 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 electronic version of a manual change-over type.

1190827-UUM-B-0818 The hotter the outside temperature, the greater the load on your system. 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 several 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 bathroom exhaust fan while showering to remove humidity.

1190827-UUM-B-0818 For Externally Mounted Air Filters COIL CLEANING 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). If an inspection by a qualified service technician indicates the coil needs to be cleaned, it can be washed with water. Replace throw away filter(s) with the same size new filter(s). BLOWER CARE Throw away filter(s) may be replaced with cleanable filter(s) at this time.
