With
power
supplied
to
indoor
and
outdoor
units,
transformer is energized.
On a cali 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.
MAINTENANCE
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.
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.
