• Check belt tension. A 3 lb. force
should deflect the belt 3/4 inches
(see Fig. 11). Readjust belt if
needed.
• Oil bearings. The blower bear-
ings 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 un-
plug motor and pump.
Remove the pump from the
mount slot. Remove the
bottom cover of the pump
as shown in Fig. 12. Clean
the pump and turn the im-
peller to ensure free

Troubleshooting Guide
Remedy
1. Check power
• Replace fuse
• Re-set breaker
• Replace cord
2. Adjust belt tension
3. Determine cause of
overheating
• Adjust belt tension
• Oil blower bearings
• Adjust pulley to
correct diameter
4. Replace motor
1. Open windows or
doors to increase air
flow
2. Adjust belt tension or
replace if needed
3. Clean pads
4. Adjust pulley
1. Adjust float
2. Tighten nut and
overflow pipe
1. Drain pan and clean
pads
operation. Remove the pump spout and check for any blockage.
After cleaning, reinstall the cover onto the pump. 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. The pump has
automatic reset thermal protection.
• Check bleed-off valve to be sure it is not clogged.
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 particu-
larly 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 finish, 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 ser-
vice from your cooler. In the event additional information is desired,
your dealer will be more than glad to assist you in every possible way.
