CAUTION:

SANITIZING THE UNIT

After cleaning, add one gallon of water at a temperature of between 75°F and 100°F to the bowl. Mix one tablespoon of approved powdered chlorine sanitizer* to a pint of water and when dissolved, pour into bowl.

Replace the lid and run the unit for two or three minutes. Shut off the unit and drain the contents through the pinch

be valve.

*Diversey - MultiChlor or equivalent powder or liquid sanitizer.

DO NOT run the refrigeration system while sanitizing the unit.

VENTILATION

AIR FLOW IS ESSENTIAL TO THE OPERATION OF THE UNIT. ALLOW AT LEAST 3 INCHES OF SPACE ON THE BACK AND SIDE OF THE DISPENSER. LINT OR DUST COLLECTING ON THE CONDENSER RESULTS IN POOR REFRIGERATION.

CLEANING THE CONDENSER

1. Turn off the Refrigeration Switch.

2. Remove the right side panel. Clean filter(s) by runnin of filter(s) and allow them to dry. Filter(s) should be replaced, if necessary. (See Parts List).

3. Clean the condenser with vacuum cleaner or brush, making sure no loose dirt goes into the dispenser.

4. Clean and replace the panels.

BOWL LEAKS

1. Do not confuse drippings from condensation on the outside of the bowl as bowl or faucet leaks. High humidity causes condensation on the bowls.

2. Be sure gasket has been installed properly. Check gasket for tears or cuts in the rubber.Tears cause

aks in the gasket.

3. Remove and inspect pinch tube for holes.
