FEATURES AND OPERATING CONTROLS 641 75844 Owners Manual E.B.C. Decanter Fig.
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 INSTRUCTIONS READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION IMPORTANT: To enable the installer to make a quality installation and to minimize installation time, the following suggestions and tests should be done before the actual unit installation is started: CAUTION: Equipment Electrical 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. Unpack the unit.
INSTALLATION INSTRUCTIONS (continued) 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. NOTE: This equipment must be installed to comply with all applicable federal, state and local plumbing codes and ordinances. WARNING: ELECTRIC SHOCK HAZARD 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 plugging the brewer into a receptacle, or otherwise connecting brewer to electrical power THE WATER TANK MUST BE FILLED.
OPERATION (continued) WATER HEATER Water temperature is sensed by an electronic water temperature probe inserted into the water tank. This temperature signal is fed to the controller. The setpoint temperature is adjustable. The controller sends a command signal to the power board based upon a comparison between the setpoint temperature and actual temperature. See page 17. The power board energizes the heating elements based on the command signal from the controller.
OPERATION (continued) IMPORTANT: DO NOT energize this brewer until the water tank has been filled. Dry firing will damage heating elements. See page 6. ELECTRONIC FEATURES Energizing the Brewer When electric power is applied to the unit, all the lights will flash four times and four beeps will sound. The unit will be OFF. Press the ON/OFF key. Four beeps will sound and all lights will flash once. The POWER indicator will remain ON.
OPERATION (continued) Quality Timer Coffee looses its freshness as it sits on a warmer. The Quality Timer flashes the warmer lights 30 minutes after the last brew to remind you that the coffee is nearing the end of its useful life. Quality Timer is normally set for 30 minutes. It can be set for 20 minutes by moving a jumper on the controller. See page 17. After Hours™ Operation During normal operation, the controller will maintain the precise brewing temperature.
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.
CLEANING INSTRUCTIONS CAUTION: Burn Hazard PROCEDURE: Clean Coffee Brewer PRECAUTIONS: Disconnect brewer from electric power. Allow brewer to cool. FREQUENCY: Daily TOOLS: Mild Detergent, Clean Soft Cloth or Sponge Bristle Brush. Brewing and serving temperatures of coffee are extremely hot. Hot coffee will cause serious skin burns. CAUTION: Electric Shock Hazard Do not submerge or immerse brewer in water. 1. Disconnect brewer from electric power. Allow brewer to cool before cleaning. 2.
TROUBLESHOOTING SUGGESTIONS SYMPTOM POSSIBLE CAUSE SUGGESTED REMEDY Water won’t heat (NOTE: Models 1016 & 1074 must have power switch ON) Brewer unplugged or circuit breaker tripped Check power supply cord Check / reset circuit breaker Temperature adjusted too low or set to OFF Turn on and set for desired temperature.
ERROR DETECTION This brewer is designed to perform a continuous internal diagnosis, and to signal faults by flashing all the lights. In fault mode, warmers, heating element and water fill solenoid are turned “off”, and most keypad functions are disabled. Error detection (all lights flashing) will occur under two conditions: • Anytime a temperature in excess of 214ºF is detected. • Temperature does not change by at least 2ºF within 4 minutes of tank heater being energized (HEAT light on).
SERVICING INSTRUCTIONS CAUTION Electric Shock Hazard Opening access panels or removing warmer plates on this brew may expose uninsulated electrical components. Disconnect brewer from electrical power before removing any panel or warmer plate. ACCESS PANELS TOP PANEL: Remove top panel to access hot water tank, thermo probe, heating elements, brew circuit tubing, faucet valve and piping. Top panel is held by two screws at the rear and a retaining lip at the front.
SERVICING INSTRUCTIONS (continued) TEMPERATURE ADJUSTMENT Unplug power cord or turn circuit breaker OFF. Remove top panel. Remove button plug from front panel. CAUTION Electric Shock Hazard These procedures involve exposed electrical circuits. These procedures are to be performed by qualified technical personnel only. Fig. 14 Checking and Adjusting Brew Temperature Pull vent tube out of tank lid and insert a thermometer of known accuracy in vent hole. Reconnect brewer to electrical power.
SERVICING INSTRUCTIONS (continued) IMPORTANT: Water pressure must be between 20 p.s.i and 90 p.s.i. flowing pressure. If water pressure exceeds this value, or if water pressure varies greatly, a pressure regulator must be installed in the water supply line. BREW TIME ADJUSTMENT The amount of water dispensed automatically during a brew cycle is controlled by the SOLENOID TIME dial of the controller. Place empty decanter under brew chamber. Press BREW button.
SERVICING INSTRUCTIONS (continued) REPLACE SOLENOID Unplug power cord. Turn OFF and disconnect water supply from brewer inlet fitting. Remove front panel. Remove two screws holding access door in place. Remove access door and solenoid. Unscrew inlet fitting cap to release solenoid from door. Remove wiring from solenoid. Large end of wrench 86660 can be used to hold solenoid inlet fitting while disconnecting supply line. Fig. 16 Fill Solenoid REPLACE FAUCET SUPPLY HOSE Unplug power cord.
SERVICING INSTRUCTIONS (continued) IMPORTANT: When replacing water faucet coil, also replace seal gaskets. REPLACE HOT WATER FAUCET COIL (Symptom: Brewer drips continuously from brew head, except when faucet valve is turned OFF.) Remove tank lid assembly per above. Remove two hex nuts hot water coil to cover. Pull coil from mounting holes. Reassemble in reverse order.
SERVICING INSTRUCTIONS (continued) SET CONTROLLER JUMPERS Placing the jumper across Q1 sets Quality Time at 20 Minutes. Placing the jumper across Q2 sets Quality Time at 30 Minutes. Removing jumpers from both Q1 or Q2 disables Quality Timer. Placing the jumper across V1 sets Valve Time Range to 60 - 180 seconds. Removing jumper from V1 sets Valve Time Range to 10 - 80 seconds. Fig. 19 Controller Jumpers REPLACE KEYPAD Unplug power cord or turn circuit breaker OFF. Shut off water supply valve.
SERVICING INSTRUCTIONS (continued) CAUTION CHEMICAL BURN HAZARD Deliming chemicals are caustic. Wear appropriate protective gloves and goggles during this procedure. Never siphon deliming chemicals or solutions by mouth. This operation should only be performed by qualified and experienced service personnel. IMPORTANT: DO NOT spill, splash or pour water or deliming solution into or over any internal component other than the inside of the water tank.
SERVICING INSTRUCTIONS (continued) 7. Set the tank back into the brewer. Reassemble the tank lid to the water tank. Make sure the gasket is properly in place, then reinstall the hold-down strap. 8. Reinstall wiring to heating element and thermostat. Reinstall the hi-limit thermostat (if removed). For automatic brewers, reassemble piping for the faucet. Verify that all internal components are dry, then reinstall the top panel. 10.
