quence 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 deter-
mine if it is with 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 and ad-
justed if necessary?
[ ] Has the heating air temperature rise been checked?
[ ] Has the indoor airflow been checked and adjusted if neces-
sary?
[ ] 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?

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, cleaning
the condenser coil, and conducting a general unit inspection
on a regular basis.
Season Maintenance - Cooling
To keep the unit operating safely and efficiently, the manufac-
turer recommends that a qualified serviceman check the entire
system at least once each year, or more frequently if condi-
tions warrant.
Examine these areas of 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 replacement
or connection tightness)
7. Condensate drain (for cleaning)
8. Inspect the unit duct connections to ensure they are physi-
cally 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.
Season Maintenance - Heating
Complete the unit inspections and service routines described
below at the beginning of each heating season.
To prevent injury or death
due to electrical shock of contact with moving parts,
lock unit disconnect switch in open position before
servicing unit.
To prevent an explosion
and possible injury, death and equipment damage, 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 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 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, perform the necessary repairs.
