INSTALLATION READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION REFER TO EXPLODED VIEWS Page 14 for COMPONENT NAMES/NUMBERS. Unpack the unit. Inspect all components for completeness and condition. Ensure that all packing materials have been removed from the unit. LEVELING THE UNIT EQUIPMENT DAMAGE Two Gallon Dispenser is NOT provided with adjustable legs.

COPPER LOOPS OR FLEX LINES (PROVIDED BY PLUMBER) SOLENOID STRAINER WASHER SHUT-OFF VALVE (PROVIDED BY PLUMBER) WATER SUPPLY CAUTION: SHOCK HAZARD WATER INLET FITTING FLOW IL2351 Fig.
OPERATION WATER HEATER Water temperature is sensed by thermobulb inserted into the water tank. Temperature is controlled by a mechanical thermostat. The setpoint temperature is adjustable by turning the thermostat shaft. Excessive temperature will trip the hi-limit safety switch, disabling the heating element. The hi-limit will automatically reset when the dispenser cools. WATER LEVEL Water level is controlled by an electronic controller. The water level probe senses chassis ground through the water.
CLEANING INSTRUCTIONS PROCEDURE: Clean Hot Water Dispenser PRECAUTIONS: Disconnect dispenser from electric power. Allow dispenser to cool. FREQUENCY: Daily TOOLS: Mild Detergent, Clean Soft Cloth or Sponge Bristle Brush CAUTION: BURN HAZARD Dispensed water is extremely hot. Hot water will cause serious skin burns. CAUTION: SHOCK HAZARD Do not submerge or immerse dispenser in water. 1. Disconnect dispenser from electric power. Allow to cool before cleaning. 2.
