PRECAUTIONS AND GENERAL INFORMATION WARNING: Electric Shock Hazard All servicing requiring access to non-insulated components must be performed by qualified service personnel. Do not open any access panels which require the use of tools. Failure to heed this warning can result in electrical shock. WARNING: Injury Hazard All installation procedures must be performed by qualified personnel with full knowledge of all applicable electrical and plumbing codes.
INSTALLATION READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION CAUTION: EQUIPMENT DAMAGE DO NOT plug in or energize this appliance until all Installation Instructions are read and followed. Damage to the Brewer will occur if these instructions are not followed. CAUTION: UNSTABLE EQUIPMENT HAZARD It is very important for safety and for proper operation that the brewer is level and stable when standing in its final operating position.
INSTALLATION (continued) The water line must terminate in a 3/8” MNTP quick-disconnect fitting, which will connect to the provided flex line. See Figure 2 below. SHOCK HAZARD Brewer 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. Fig. 2 Water Supply Installation In some areas, local codes require a backflow preventer (check valve) to be installed on the inlet water line.
OPERATION Fig. 4 Brewer Operation Diagram A. START-UP For initial start-up, or if the brewer has not been used for an extended period of time: • Be sure spray disk and brew gasket are properly installed in the brew head. • Be sure the water supply is properly connected and the water supply valve is turned ON. • Be sure the WATER TANK IS FILLED BEFORE energizing the tank heater the water tank must be filled. Place an empty decanter under the brew head.
OPERATION (continued) WATER HEATER Water temperature is sensed by a thermobulb inserted into the water tank. This temperature signal is fed to the thermostat, which controls line power to the heating element. The setpoint temperature is adjustable at the thermostat. The element is protected from overtemperature by a hi-limit thermostat. Fig.
