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 REFER TO EXPLODED VIEWS 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. Verify that the Spray Head Gasket and Spray Disk are properly installed. CAUTION: LEVELING THE UNIT EQUIPMENT Damage Verify that provided adjustable legs are installed at each corner of the brewer.
INSTALLATION (continued) A water shut-off valve should be installed on the incoming water line in a convenient location (Use a low restriction type valve, such as a 1/4-turn ball valve, to avoid loss of water flow thru the valve. NSF requires that the brewer be able to be moved for cleaning underneath. A flex line or loops of copper tubing will satisfy this requirement. See Figure 2 below. COPPER LOOPS OR FLEX LINES (PROVIDED BY PLUMBER) WATER INLET FITTING FLOW IL1652 Fig.
OPERATION IL1653 Fig. 4 Brewer Operation Diagram 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 connecting brewer to electrical power the water tank must be filled. Place an empty decanter under the brew head.
OPERATION (continued) 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. HI-LIMIT THERMOSTAT THERMOBULB The setpoint temperature is adjustable at the thermostat. The element is protected from overtemperature by a hi-limit thermostat. HEATER ELEMENT THERMOSTAT Fig.
BREWING COFFEE CAUTION: Burn Hazard Exposed surfaces of the brewer, brew chamber and decanter may be HOT to the touch, and can cause serious burns. CAUTION: Burn Hazard To avoid splashing or overflowing hot liquids, ALWAYS place an empty decanter under the brew chamber before starting the brew cycle. Failure to comply can cause serious burns. CAUTION: Burn Hazard After a brew cycle, brew chamber contents are HOT. Remove the brew chamber and dispose of used grounds with care.
