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 pumps. When cooler is not used for extended periods unplug the motor and pumps 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.
