3 years heavy duty or 5 years normal duty. When
lubrication is necessary, send motor to authorized
motor repair shop.

beginning of every cooling season or more often if
required. Use ordinary garden hose at a pressure
high enough to clean efficiently. Eor best results,
unscrew and remove unit top cover. Insert hose
nozzle between fan blades, spray coil fins from
inside-to-outside the unit. If unit has a double-row
coil, loosen screws to separate coils, carefully pull
outer row of coils away from inner row, and flush
dirt toward outside of both coils. Flush dirt from
basepan by spraying water thru top of unit. Avoid
splashing mud on coil or water on the fan motor.
