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
attachment. 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. Clean the drain pan and condensate drain by removing all
foreign matter from the pan. Flush the pan and drain tube with
clear water. Do not splash water on the insulation, motor, wiring,
or air filter(s). If the drain tube is restricted, clear it with a
“plumbers snake” or similar probe device. Ensure that the auxiliary
drain port above the drain tube is also clear

D.

CONDENSER FAN

CAUTION: Keep the condenser fan free from all ob-
structions to ensure proper cooling operation. Never place
articles on top of the unit. Damage to unit may result.

1. Remove 6 screws holding condenser grille and motor to top

cover.

2. Turn motor/grille assembly upside down on top cover to

expose the fan blade.

3. Inspect the fan blades for cracks or bends.

4. If fan needs to be removed, loosen the setscrew and slide

the fan off the motor shaft.

5. When replacing fan blade, position blade so that the hub is

1/8 in. away from the motor end (1/8 in. of motor shaft will
be visible).

6. Ensure that setscrew engages the flat area on the motor shaft

when tightening

7. Replace grille.

* Air delivery values are based on operating voltage of 230v or 460v, wet coil, without filter or electric heater. Deduct filter and electric heater pressure drops to obtain static
pressure available for ducting.

NOTES:
1. Do not operate the unit at a cooling airflow that is less than 350 cfm for each 12,000 Btuh of rated cooling capacity. Evaporator coil frosting may occur at airflows below

this point.

2. Dashes indicate portions of table that are beyond the blower motor capacity or are not recommended.
