INSTALLATION INSTRUCTIONS

SEQUENCE OF OPERATION

With power supplied to indoor and outdoor units,

transformer is energized.

On a call for cooling, the thermostat makes circuits R−Y

and R−G. Circuit R−Y energizes contactor, starting

outdoor fan motor and compressor. Circuit R−G

energizes indoor unit blower relay, starting indoor blower

motor.

When thermostat is satisfied, its contacts open,

de−energizing contactor and blower relay. Compressor

and motors stop.

NOTE: If indoor unit is equipped with a time−delay relay

circuit, the blower runs an additional length of time to

increase system efficiency.

NOTE: The RED (R) low voltage lead wire is provided

only for powering the Comfort Alert device. To utilize the

Comfort Alert device, connect the RED (R) low voltage

lead wire directly to 24 VAC hot at the indoor unit or

thermostat. Use one of the spare wires in the thermostat

cable to bring 24 VAC hot out to the outdoor unit. If there

are no spare wires in the thermostat cable, leave the

insulation on the end of the RED low voltage lead wire to

avoid an electrical short. The air conditioner will

function normally without the RED (R) low voltage

lead wire connected.

The Comfort Alert device operates by monitoring the

compressor power leads and the thermostat demand

signal (Y terminal). It draws constant 24 VAC power at

the R and C terminals.

MAINTENANCE

Condensate Drain

During the cooling season, check monthly for free flow of

drainage and clean if necessary.

Cleanliness

These tips will help keep the air conditioner looking better

and working more efficiently:

1. Free flow of air is essential. Keep fences, shrubs,

trash cans, and other obstructions at least 18

inches (0.5m) from all coil inlets.

2. Keep the coil free of grass clippings, leaves,

weeds, and other debris.

NOTE: Coil may occasionally require cleaning with a

liquid solution. The coil must be cold when

cleaning. Use an alkaline based cleaner only.

Cleaning a hot coil or using an acid based cleaner

will remove the paint from the fins and may clog

the coil.

3. Never use a weather cover over the outdoor unit

unless it is a ventilated type or made of breathable

fabric that will allow moisture to evaporate rapidly.

A cover that holds moisture in the unit will cause

more rust build−up and damage than normal

exposure to weather.

Specifications subject to change without notice.
