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 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 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 service from your cooler. In the event addi-
tional information is desired, your dealer will be more than glad
to assist you in every possible way.
