• Check belt tension. A 3 lb. force
should defl ect the belt 3/4 inches (see
Fig. 11). Readjust belt if needed.
• Oil bearings. The blower bearings and
cooler motor in this unit should be oiled
with a few drops of non-detergent 20/30
weight oil once each year. The motor
does not need oil if it has no oil lines for oiling. Motors that have no
oil lines are lifetime oiled at the factory and require no further oiling
for the life of the unit.
CAUTION: Do not over oil. Over oiling can cause motor burn
out, due to excessive oil getting into motor winding.
• Clean pump. Cleaning the
pump is necessary once a year
at start-up. For your safety,
turn unit off and unplug motor
and pump. Remove the pump
from the mount slot. Remove
the base of the pump as shown
in Fig. 12. Clean the pump and
turn the impeller to ensure free
operation. Remove the pump

spout and check for any blockage. After cleaning, reinstall the base
onto the pump. Press fi rmly to make sure it is secure. Reattach the
pump to the mount in the cooler using the plastic retainer to ensure
that the pump will not overturn. Do not forget to replace the spout
and water delivery tube onto the pump outlet.
• Check bleed-off valve to be sure it is not clogged.

• Drain water. Always drain all of the water out of the cooler and water
supply line when not in use for prolonged periods, and particularly
at the end of the season. Keep the water line disconnected from both
the unit and water supply so that it does not freeze.
• Unplug motor and pump. When cooler is not used for extended
periods unplug the motor and pump from inside cooler.
• Cover unit. To protect the life of the fi nish, a cover for the unit is
suggested in extended periods of non use.
By following the operating, installation, and maintenance suggestions
as outlined, you can get many years of efficient and satisfactory service
from your cooler. In the event additional information is desired, your
dealer will be more than glad to assist you in every possible way.
