MAINTENANCE
Outdoor Coil Cleaning — Inspect coil periodically.
Clean coil with water at the beginning of every
cooling season or more often if required. Use
ordinary garden hose at a pressure high enough to
clean efficiently. For best results, unscrew and
remove unit top cover (grille). Insert hose nozzle
between fan blades and spray coil fins from
inside-to-outside the unit or top to bottom be­
tween rows of tubing. If unit has a double-row coil,
loosen screws to separate coils. Pull outer row of
coils away from inner row and flush dirt toward
outside of both coils. Flush dirt from base pan by
spraying water thru top of unit. Avoid splashing
mud on coil or water on fan motor. Make sure
water drainage holes under outdoor coil are not
obstructed.
Lubrication
FAN MOTOR BEARINGS - Oiling holes are
provided at each end of outdoor unit fan motor.
Remove fan motor and lubricate motor with 32
drops (16 drops per hole) of SAE-10 nondetergent
oil at intervals described below:
a.
Annually, when environment is very dirty,
ambient temperature is higher than 105 E and
average unit operating time exceeds 15 hours a
day.
b. Every 3 years when environment is reasonably
clean, ambient temperature is less than 105 F
and unit operating time averages 8 to 15 hours
a day.
c. Every 5 years when environment is clean,
ambient temperature is less than 105 F and unit
operating time averages less than 8 hours a day.
