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 (0.5m) 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.
