The minimum
maintenance
requirements
for this equipment
are as
follows:
1. Inspect
air filter(s)
each
month.
Clean
or replace
when
necessary.
2. Inspect
indoor
coil, drain pan. and condensate
drain each
cooling
season for cleanliness.
(;lean when necessary.
3. Inspect blower motor and wheel for cleanliness
each cooling
season.
(;lean when necessary.
4. Check electrical
connections
for tightness
and controls
for
proper
operation
each
cooling
season.
Service
when
necessary.
Step I--Air
Filter
IMPORTANT:
Never operate the unit without
a suitable
air filter
in the return- air duct system. Always replace the filter with the same
dinmnsional
size and type as originally
installed.
See Table 1 for
recommended
filter sizes.
Inspect
air
filter(s)
at
least
once
each
month
and
replace
(throwaway-type)
or clean (cleanable-type)
at least twice during
each cooling
season
and
twice
during
the heating
season,
or
whenever
the filter becomes
clogged
with dust and lint.
Step 2--Indoor
Fan and Motor
(IFM)
NOTE:
All motors
are pre-lubricated.
Do not attempt to lubricate
these motors.
For longer life, operating
economy,
and continuing
efficiency, clean
accumulated
dirt and grease
from
the blower
wheel
and motor
annually.
Step 4_Outdoor
Fan
UNIT
OPERATION
HAZARD
Failure
to follow
this caution
may result in damage
to unit
components.
Keep the condenser
fan free from
all obstructions
to ensure
proper
cooling
operation.
Never place articles
on top of the
unit.
1. Remove
4 screws
holding
outdoor
grille
and
motor
to top
cover.
2. Turn
motor/grille
assembly
upside
down
on top
cover
to
expose
fan blade.
3. Inspect
the fan
blades
for cracks
or bends.
4.
If fan needs
to be removed,
loosen
setscrew
and slide
fan off
motor
shaft.
5.
When
replacing
fan
blade,
position
blade
according
to the
table
shown
in Fig.
19.
6. Ensure
that set screw
engages
the flat area on the motor
shaft
when
tightening.
7. Replace
grille.
ELECTRICAL
SHOCK
HAZARD
Failure to follow this warning
could result in personal
injury
or death.
Disconnect
and tag electrical power to the unit before cleaning
and lubricating
the blower
motor and wheel.
Step 3--Outdoor
Coil, Indoor
Coil, and Condensate
Drain Pan
Inspect the condenser
coil. evaporator
coil, and condensate
drain
pan at least once each year.
The coils are easily cleaned
when dry; therefore,
inspect and clean
the coils either before
or after each cooling
season.
Remove
all
obstructions,
including
weeds
and shrubs,
that interfere
with the
airflow
through
the condenser
coil. Straighten
bent fins with a fin
comb.
If coated
with dirt or lint, clean the coils with
a vacuum
cleaner, using the soft brush attachnmnt.
Be careful not to bend the
fins. If coated with oil or grease, clean the coils with a mild detergent
and water solution.
Rinse coils with clear water, using a garden hose.
Be careful not to splash water on motors,
insulation,
wiring,
or air
filter(s). For best results,
spray condenser
coil fins from inside to
outside the unit. On units with an outer and inner condenser
coil, be
sure to clean between
the coils. Be sure to flush all dirt and debris
from the unit base.
Inspect the drain pan and condensate
drain line when inspecting
the
coils. (;lean the drain pan and condensate
drain by removing
all
foreign
matter from the pan. Flush
the pan and drain trough
with
clear water. Do not splash water on the insulation,
motor, wiring, or
air filter(s). If the drain trough is restricted,
clear it with a "plumbers
snake" or similar probe device.

Step 5--Electrical
Controls
and Wiring
Inspect
and check the electrical
controls
and wiring
annually.
Be
sure to turn off the electrical
power
to the unit.
Remove
access panel to locate all the electrical controls
and wiring.
Check
all electrical
connections
for tightness.
Tighten
all screw
connections.
If any smoky
or burned
connections
are noticed,
disassemble
the connection,
clean all the parts, re-strip
the wire end
and reassemble
the connection
properly
and securely.
After inspecting
the electrical
controls
and wiring,
replace
all the
panels.
Start the unit, and observe
at least one complete
cooling
cycle to ensure
proper
operation.
If discrepancies
are observed
in
operating
cycle,
or if a suspected
malfunction
has occurred,
check
each
electrical
component
with
the
proper
electrical
instrumentation.
Refer to the unit wiring
label when making
these
checks.
Step 6--Refrigerant
Circuit
Inspect
all refrigerant
tubing connections
and the unit base for oil
accumulation
annually.
Detecting
oil
generally
indicates
a
refrigerant
leak.
