Perform all of the indicated maintenance procedures at
the intervals scheduled. This will prolong the life of the
unit and reduce the possibility of costly equipment
failure.
Monthly
Conduct the following maintenance inspections once
per month.
☐ Check unit wiring to ensure all connections are tight
and that the wiring insulation is intact.
☐ Inspect the condenser coils for dirt and debris. If the
coils appear dirty, clean them.
☐ With the unit operating in the cooling mode, check
the suction and discharge pressures and compare
them with Pressure Curve values. Record these
readings on the
“Maintenance Log,” p. 36 .
Annually (Cooling Season)
The following maintenance procedures must be
performed at the beginning of each cooling season to
ensure efficient unit operation.
☐ Perform all of the monthly maintenance
inspections.
☐ With the unit operating, check unit superheat and
record the reading in the
“Maintenance Log,” p. 36 .
☐ Remove any accumulation of dust and/or dirt from
the unit casing.
☐ Remove corrosion from any surface and repaint.
Check the gasket around the control panel door to
ensure it fits correctly and is in good condition to
prevent water leakage.
☐ Inspect the control panel wiring to ensure that all
connections are tight and that the insulation is
intact.
N No otte e:: Condenser fan motors are permanently
lubricated.
☐ Check refrigerant piping and fittings for leaks
☐ Inspect the condenser coils for dirt and debris. If the
coils appear dirty, clean them.
Coil Cleaning
Regular coil maintenance, including annual cleaning-
enhances the unit's operating efficiency by minimizing:
• compressor head pressure and amperage draw
• water carryover
• fan brake horsepower
• static pressure losses
At least once each year — or more often if the unit is
located in a “dirty” environment — clean the coil using
the instructions outlined below. Be sure to follow these
instructions as closely as possible to avoid damaging
the coils.
Tube and Fin
N No otte e:: To clean refrigerant coils, use a soft brush and a
sprayer. Contact your local Parts Center for
appropriate detergents.
1. Remove enough panels from the unit to gain safe
access to coil.
2. Straighten any bent coil fins with a fin comb.
3. Remove loose dirt and debris from both sides of the
coil with a soft brush.
4. Mix the detergent with water according to the
manufacturer's instructions. If desired, heat the
solution to 150° F maximum to improve its
cleansing capability.
5. Pour the cleaning solution into the sprayer.
6. Spray the leaving-airflow side of the coil first; then
spray the opposite side of the coil. Allow the
cleaning solution to stand on the coil for five
minutes.
7. Rinse both sides of the coil with cool, clean water.
8. Inspect both sides of the coil; if it still appears to be
dirty, repeat Step 7 and 8.
9. Reinstall all of the components and panels removed
