Installation guide

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.

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 (0.5 m) 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 nmst 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.
