Final Installation Checklist
[ ] Does unit run and operate as described in the "Sequence
of Operation" in the unit Service Facts?
[ ] Is the condenser fan and indoor blower operating correctly,
with proper rotation and without undue noise?
[ ] Is the compressor operating correctly and has the system
been checked with a charging chart?
[ ] Have voltage and running currents been checked to
determine if it is within limits?
[ ] Have the air discharge grilles been adjusted to balance the
system?
[ ] Has the ductwork been checked for air leaks and conden-
sation?
[ ] Has the furnace manifold pressure been checked ?
[ ] Has the heating air temperature rise been checked?
[ ] Has the indoor airflow been checked and adjusted if
necessary?
[ ] Has the unit been checked for tubing and sheet metal
rattles and are there unusual noises to be checked?
[ ] Are all covers and panels in place and properly fastened?
[ ] Has the owner or maintenance personnel been given this
manual, warranty, and been instructed on proper operation
and maintenance?
Routine Maintenance By Owner
You can do some of the periodic maintenance functions for
your unit yourself; this includes replacing (disposable) or
cleaning (permanent) air filters, cleaning unit cabinet, clearing
the condenser coil, and conducting a general unit inspection
on a regular basis.
!
WARNING:
panels to service unit, disconnect power supply. Failure to
disconnect power before attempting any servicing can
result in severe injury or death.
Air Filters
It is very important to keep the central duct system air filters
clean. Be sure to inspect them at least once each month when
the system is in constant operation. (In new buildings, check
the filters every week for the first 4 weeks.)
If you have disposable type filters, replace them with new ones
of the same type and size.
Note: Do not attempt to clean disposable filters.
Permanent type filters can be cleaned by washing with a mild
detergent and water. Ensure that the filters are thoroughly dry
before re-installing them in the unit (or duct system).
Note: Replace permanent filters annually if washing fails to
clean, or they show signs of deterioration. Be sure to use the
same type and size as was originally installed.
Before removing access
Condenser Coil
Unfiltered air circulates through the unit's condenser coil and
can cause the coil's surface to become clogged with dust, dirt,
etc.. To clean the coil, vertically (i.e., with the fins) stroke the
coil surface with a soft bristled brush.
Keep all vegetation away from the condenser coil area.

Cooling Season
To keep your unit operating safely and efficiently, the manu-
facturer recommends that a qualified serviceman check the
entire system at least once each year, or more frequently if
conditions warrant. Your serviceman may examine these
areas of your unit:
1. Filters (for cleaning or replacement)
2. Motors and drive system components
3. Economizer gaskets (for possible replacement)
4. Condenser coils (for cleaning)
5. Safety Controls (for mechanical cleaning)
6. Electrical components and wiring (for possible replace-
ment or connection tightness)
7. Condensate drain (for cleaning)
8. Inspect the unit duct connections to ensure they are
physically sound and sealed to the unit casing.
9. Inspect the unit mounting support to see that it is sound.
10. Inspect the unit to ensure there is no obvious deterioration.
Maintenance Performed by Serviceman -
Heating Season
Complete the unit inspections and service routines described
below at the beginning of each heating season.
WARNING:
due to electrical shock of contact with moving parts, lock
unit disconnect switch in open position before servicing
unit.
WARNING:
!
possible injury,death and equipment damage from an
explosion, do not store combustible materials, gasoline or
other flammable vapors and liquids near the unit.
[ ] Visually inspect the unit to ensure that the airflow required
for combustion and condenser coil is not obstructed from
the unit.
[ ] Visually inspect the flue stack to ensure the exhaust path is
clear and free of obstructions.
[ ] Inspect the control panel wiring to verify that all electrical
connections are tight, and that wire insulation is intact.
[ ] Check the operation of the gas ignition system: To do this,
turn off the gas supply with the unit operating to verify that
the gas valve closes, and that a re-ignition cycle is initiated
by the unit.
[ ] Visually inspect all of the unit's flue product passageways
for excessive deposit buildup and corrosion. If buildup or
corrosion is apparent, a qualified serviceman should
perform the necessary repairs.
