6. The unit will revert to the energy-saver mode some time after the last brew, based on AFTER HOURS TIME setting. WARNING: RISK OF INJURY The following servicing sections are for operator reference only. All servicing and/or repairs must be performed by a qualified technician Reset Hi-Limit Thermostat 240 V & Dual Voltage Units 14 SERVICING INSTRUCTIONS - ELECTRICAL FUNCTION 1. Pressing the POWER key energizes the unit. The POWER LED will glow whenever the unit is ON. 2. Automatic fill is accomplished via a FILL SOLENOID (32) and a WATER LEVEL PROBE (7). The probe senses ground through the water in the tank. When the water level falls below the probe and ground is no longer sensed, the CONTROLLER (20) energizes the fill solenoid (32) until the water level again reaches the water level probe. 3. Pressing any VOLUME key selects that pre-programmed volume. 4. Pressing the BREW key begins the brew cycle. Pressing the CANCEL key at any time during the brew cycle terminates the brew. The BREW SOLENOID (18) is energized by the CONTROLLER (20) for a time determined by the BREW TIME setting. A second brew can be started only after the brew time plus the DRIP OUT time has elapsed. 5. Brew water temperature is controlled via a WATER TEMPERATURE SENSOR (3) and a HEATING ELEMENT (15) controlled by a TRIAC (17) electronic switch. The element is energized according to the sensed water temperature and the BREW TEMP setting. An over-temperature condition will trip the HI-LIMIT THERMOSTAT (4), de-energizing the heating element. Note: On 120 volt units, hi-limit will automatically reset once the tank has cooled by approximately 30.F. On 240 volt units and dual voltage units, the hi-limit must be manually reset by pressing the red button after the unit cools. 6.

Wear appropriate protective gloves and goggles during this procedure. CAUTION -CHEMICAL BURN HAZARD Never siphon de-liming chemicals or solutions by mouth. This operation must only be performed by qualified and experienced service personnel. IMPORTANT: DO NOT spill, splash or pour water or de-liming solution into or over any internal component other than the inside of the water tank. IMPORTANT: DO NOT allow any internal components to come into contact with the de-liming solution. Take care to keep all internal components dry. NOTE: Repeat steps 4 thru 7 as required to remove all scale and lime build-up. NOTE: Normally, silicone hoses do not need to be de-limed. Should de-liming hoses become necessary, Bloomfield Industries recommends replacing the hoses. 1. Disconnect brewer form the electrical supply. Turn off the water supply and disconnect water supply from the brewer inlet fitting. 2. Remove the top panel or top warmer section to gain access to internal components. 3. Disconnect water level sensor and water temperature sensor from the controller. On 120V units, slip hi-limit thermostat from under its holder clip. Disassemble the three lid clips and lift the lid off of the water tank. Store lid assembly in a safe location. 4. Mix de-liming solution according to the manufacturer’s directions. Add the de-liming solution to the water tank. Set lid assembly back on tank. Allow to sit for 30 minutes, or as directed by the manufacturer. 5. At end of soaking period, remove lid assembly from tank. Thoroughly rinse interior components of lid assembly with clear water. Wipe temperature sensor and water level sensor with a clean, soft cloth. Store lid assembly in a safe location. 6. Using a stiff bristle brush, scrub the coils of the heating element a...
