WARNING ELECTRIC SHOCK HAZARD: Dispenser must be properly grounded to prevent possible shock hazard. DO NOT assume a plumbing line will provide such a ground. Electrical shock will cause death or serious injury. IMPORTANT: Supply power must match nameplate for voltage and phase. Connecting to the wrong voltage will damage the appliance or result in decreased performance. Such damage is not covered by warranty. IMPORTANT: Do not connect dispenser to electrical power until you are ready to fill the tank. IMPORTANT: The ground prong of the plug is part of a system designed to protect you from electrical shock in the event of internal damage. Never cut off the ground prong nor twist a blade to fit an existing receptacle. Contact a licensed electrician to install the proper circuit and receptacle. NSF requires that the unit be able to be moved for cleaning underneath. A flex line or loops of copper tubing will satisfy this requirement. See Figure 2 below. In some areas, local codes require a backflow preventer (check valve) to be installed on the inlet water line. If a backflow preventer is used, you must install a water hammer arrester in the incoming line, between the backflow preventer and the brewer inlet, as far away from the brewer as space will allow. This will relieve the excessive back pressures that can cause faucet leaks and solenoid malfunctions. ELECTRICIAN’S INSTALLATION INSTRUCTIONS REFER TO ELECTRICAL SPECIFICATIONS -Page 1 Check the nameplate to determine correct electrical service required for the dispenser to be installed. IMPORTANT: Before connecting to electricity, make sure dispenser is connected to the water supply. Model 1222 is equipped with a cord and plug. It requires a 115 - 125 volt 20 amp circuit (50/60 Hz, 2 wire plus ground, with NEMA 5-15R). Model 1222CA is equipped with a cord and plug. It requires a 115 - 125 volt 15 amp circuit (50/60 Hz, 2 wire plus ground, with NEMA 5-15R). CAUTION: EQUIPMENT DAMAGE DO NOT connect Model 1225 to a circuit with voltage higher than 208V. Equipment damage will result. Such damage is NOT covered by warranty. Model 1225 is equipped with a cord and plug. It requires a 208 volt 30 amp circuit (50/60 Hz, 2 wire plus ground, with NEMA 6-30R). Model 1226 is equipped with a cord and plug. It requires a 240 volt 30 amp circuit (50/60 Hz, 2 wire plus ground, with NEMA 6-30R). Fig. 2 Water Supply Installation OPERATION 6 Fig. 3 Dispenser Operation Diagram A. START-UP For initial start-up, or if the dispenser has not been used for an extended period of time: ¦ Be sure the water supply is properly connected and the water supply valve is turned ON. ¦ Be sure the WATER TANK IS FILLED. IMPORTANT: Fill the water tank before energizing tank heater 1. Be sure TANK HEATER SWITCH is "OFF", then plug unit into an appropriate receptacle. "POWER" light will glow any time unit is connected to electric power. 2. The fill solenoid will open and water tank will begin filling. 3. When the fill solenoid shuts off, open the faucet. Run water until the fill solenoid is energized again, then close the faucet. This will purge all air from the system. When fill solenoid shuts off, tank is filled. 4. Press tank heater switch to "ON". Tank heaters will energize. When the "HOT WATER READY" light glows, water is ready to use. B. USE 1. Always use a container suitable for hot water. 2. Hold container under faucet. Pull faucet handle to dispense hot water. Release handle to stop dispensing. IMPORTANT: Be sure tank is filled with water before pressing tank heater switch to ON. 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. When the water level is below the probe no ground is sensed. The controller opens the fill solenoid until the water level makes contact with the probe.
