CLEANING COIL - Coil should be washed out with water
or blow out with compressed air. The draw thru design
causes dirt and debris to build up on the outside of the
coils. Clean coil as follows:-
1) Turn off unit power.
2) Using a water hose or other suitable equipment, flush
coil from the inside to remove dirt. (See Fig. 13). Be
sure to flush all dirt and debris from drain holes in base
of unit. Fan motor is water proof.
Clean coil annually or as required. Fins are not continuous
through coil sections. Dirt and debris may pass between the
row of fins and become trapped between the row of fins and
restrict condenser air flow. Use a flashlight to determine if
dirt or debris has collected between coil section.
LUBRICATION
- Fan Motor is permanently sealed lubricated
bearings. Do not oil. Compressor is supplied charged with
oil. Replace oil when lost. See Table 1 for oil recharge.
FAN ADJUSTMENT - Shut off main power supply. Remove
condenser fan grille, and loosen fan hub setscrews. Adjust
fan depth as shown in Fig. 14. Tighten setscrew and
replace fan grille.

SERVICE AND MAINTENANCE
CAUTION
BEFORE PERFORMING RECOMMENDED
MAINTENANCE AND SERVICE, BE SURE UNIT MAIN
POWER SWITCH IS TURNED OFF. FAILURE TO DO
SO MAY RESULT IN ELECTRIC SHOCK OR INJURY
FROM ROTATING FAN BLADE.
CAUTION
To prevent compressor damage or personal injury,
observe the followings:.
-
DO NOT overcharge system with refrigerant
-
DO NOT operate unit in a vacuum or at
negative pressure
-
Dome temperature may be hot
-
In 3-phase application, incorrect phasing will
cause reverse rotation, resulting in elevated
noise levels, equalized pressure and reduced
current draw. Correct by reversing power
connection L1 and L2 on contactor.
For continued high performance and to minimize possible
equipment failure, periodic maintenance MUST BE
performed on this equipment.
Leave User’s Manual with owner. Explain system
operation and periodic maintenance requirements outlined
in the manual. Frequency of maintenance may vary
depending on geographic areas, such as coastal
applications which require more frequent maintenance.
