PERIODIC MAINTENANCE
2. WINTERIZE YOUR SYSTEM WITH
AIR SUPPLY SHUT OFFS
If the blower coil unit and air
distribution system are located in an
unheated area such as the attic (and
the system is used for cooling only),
winterizing the system helps prevent
any accumulation of moisture in the
duct work.
•Plug Air Outlets (Optional)
Winter supply air shut-offs are available
to plug off each air outlet. A plate
should also be installed across the face
of the filter in the return air box.
Check with your authorized
contractor to provide these optional
items.
3. CHECK CONDENSATE TRAP
AND DRAINS
The condensate drain should be
checked periodically to assure there is
unimpeded flow of condensate water
from the blower coil drain pan. At the
start of each cooling season it is
advisable to flush the drain pan, drain
trap and line with water. Dirt can
accumulate in the trap and block the
drain opening. Also check the drain
connection on the secondary drain pan
when provided under the unit. This
drain must also remain unclear to
provide the back-up protection
intended.
On cooling only installations where the
blower coil unit is located in areas such
as attics, which may be subject to
freezing, the drain trap should be
drained or filled with anti-freeze/water
mixture.
4. KEEP OUTDOOR UNIT FREE OF
DEBRIS
The outdoor condensing unit should
be checked periodically to assure
trouble free operation.
•SHUT OF POWER __
SEE “UNIT DISCONNECTION”
IMPORTANT: Shut off power to the
condencing unit before washing or
working near the unit.
•Clean Outdoor Condensing Unit
Keep leaves, grass, and foreign
matter out of the condenser coil
by flushing clean with a garden
hose (check condensing unit
manufacturer’s instructions).
Keep the condenser fan blades
clear of dirt and dust
accumulation.
•Trim Shrubbery
Keep shrubbery trimmed around
the unit to maintain unrestricted
air flow to and from the
condenser coil.
5. CONDENSING UNIT
LUBRICATION
Check the manufacturer’s
instructions for the condenser fan
motor lubrication recommendations. If
the motor does not have oil holes for
tubes, it is permanently lubricated and
requires no oiling.

MAINTENANCE/UNIT DISCONNECTION
Outdoor Condensing Unit
Typical __ Configuration may vary
Disconnect Switches:
Be sure you know where the
power disconnect switches are
located for both the indoor blower
coil unit and the outdoor
condensing unit. If unusual noise,
vibration or any other
uncharacteristic performance is
evident do not hesitate to turn off
the blower coil unit and condensing
unit with the disconnect switches
and call your authorized contractor.

P.R.O.S.
(POSITIVE REGULAR OPERATING STEPS)
Help maximize the efficiency and economy of your stem by following these simple
guidelines:
Keep all windows and doors closed.
If storm windows are used, keep
them in place during the cooling
season to help reduce heat gain.
Pull drapes or shades where the
sunlight is streaming through the
windows during the cooling season.
During the winter, keep drapes and
shades open during the day,
allowing the sun to provide
supplementary heat.
•Keep filters clean, replace
disposable types periodically.
Check the filter monthly.
•Vent clothes dryer to the outside __
otherwise the moisture from
washing mush be removed by the
cooling system.
•Keep attic vents open and use an
attic power ventilator to reduce attic
temperatures. Attic space can
become extremely hot unless it is
well ventilated.
•Take advantage of the great
dehumidifying effect. Comfort levels
can be maintained at higher
thermostat levels settings than with
conventional systems that take out
30% less moisture.
•Set thermostats at the desired
temperature and forget it.
Thermostat jiggling only aggravates
the system causing frequent
changes in humidity level and by
increase operating costs.
•Leave the system on even when
away for a day or more. When the
system is off, heat and moisture
build up in the house and it can cost
more to restore comfort than to
maintain it.
•If possible, do those chores that
contribute heat and moisture
(washing, drying, mopping, etc.) in
the morning or evening. This
permits the cooling system to
overcome the added loads of these
activities before (or after) the peak
load in the afternoon.
•Use bathroom exhaust fans or open
windows slightly during showers or
baths to let excess moisture
escape.
•Use kitchen exhaust fans when
cooking during the cooling season.
Heat added by a cooking device
must be removed by your cooling
system if not exhausted.
•Expect the unit to operate after
sundown
__ heat builds up in the structure and
is retained after the sun sets. This
“flywheel” effect can be overcome
by operating the system even when
outdoor temperatures have
dropped.
•Keep windows closed after the sun
sets. While night air may be cooler,
it may be humid and can cause
equipment to run longer the next
day.
•Keep outdoor condensing unit free
of shrub overgrowth and vegetation.
Assure unrestricted air flow for
intake and discharge of the
condensing unit.
•Keep heat generating devices such
as lamps, TV or electronic
equipment away from vicinity of the
thermostat so it can more
accurately sense room temperature.

BEFORE CALLING FOR SERVICE __
3Check that disconnect switches for both indoor and outdoor units are on.
See “UNIT DISCONNECTION.”
3Check that fuses are not blown or circuit breakers are not tripped.
3Check that the thermostat system switch is in the proper position __
HEAT or COOL.
When cooling, more the thermostat setting several degrees below room
temperature and see if the unit comes on. If a clock thermostat is used, check
to be sure the time setting is not twelve hours off.
3Check that filters are clean.
3Check for manual High Pressure Reset Button on condensing unit. Does unit
start when reset button is pushed?
3Check that winter shutoffs and filter plate have been removed.
