• Clean pump. Cleaning the pump is necessary once a year at
start-up. For your safety, turn unit off and unplug from power
receptacle. Remove the pump from the mount slot. Remove the
base of the pump (Fig. 7). 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.
• Oil motor. The cooler motor in this unit
should be oiled with a few drops of non-
detergent 20/30 weight oil once each year.
The oil ports are located on each side of
the motor (Fig. 8). Motors that have no oil
ports 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.
Winter Shut Down
• Drain water. Always drain all of the water out of the cooler and
water supply line when not in use for prolonged periods, and
par ticularly at the end of the season. Keep the water line discon-
nected from both the unit and water supply so that it does not
freeze.
