Servicing The Unit
203
Cleaning the Condenser Coil
Clean the condenser coil by blowing low pressure compressed air or a medium pressure warm water
spray from the inside of the coil outward (opposite direction of normal airflow). Inspect coil and fins for
damage and repair if necessary.
If a build up of salt or debris is present on the condenser coil, the coil should be cleaned using a mild
alkaline cleaner with a pH of 9.5 to 10.5. For example, a 2-3 percent solution of SIMPLE GREEN
®
would
make a suitable cleaning solution. Apply the solution using a pressure spray/wash type apparatus. Spray
the condenser coil thoroughly from both the inside and outside of the coil. Always thoroughly rinse the
coil with a fresh water spray.
Also inspect the directional airflow condenser grille for damage. This grille directs the condenser airflow
out and away from the unit to increase the efficiency of the condenser coil by preventing the recirculation
(short cycling) of warm air through the coil. Abnormally high head pressures may result if this special
condenser grille is damaged or missing.
Cleaning the Evaporator Coil
Clean the evaporator coil by blowing low pressure compressed air from the bottom side of the coil
upward (opposite direction of normal airflow). Inspect coil and fins for damage and repair if necessary.
Cleaning the Defrost Drains
Clean the defrost drains every 1,000 operating hours to be sure the lines remain open.
Positioning the Condenser Fan Blade
Place fan blade on motor shaft with hub located on the outside of the blade for proper airflow direction.
When mounting the fan blade and hub assembly on the fanshaft, center the assembly in the orifice.
Position the front of the fan blade 10 mm (0.4 in.) in from the outer edge of the fan orifice.
CAUTION: Air pressure or water spray must not be high enough to damage coil fins
