BCI, BC2 BC120, BC240 BC301, BC302 Single Timer (L264A) Dual Timer (58026) 120 Triple Timer Dual Timer (58027) 240 (Dual Voltage)(L410C) 3. THERMOSTAT ADJUSTMENT The BC Brewers are factory set to deliver hot brewing water at 200' F. The water temperature, at the spray head, should be between 195' F-203' F with the thermostat knob at its maximum clockwise position. If adjustment is necessary, proceed as follows: a. To RAISE water temperature, turn temperature control knob to its maximum clockwise position. Remove the knob and locate slotted adjustment screw inside hollow thermostat shaft. Using a narrow-bladed screwdriver, engage slotted adjustment screw and turn it 1/4 turn counter-clockwise. The thermostat will cut in and the Green ready light will go off. When Green ready light comes on after a few minutes, measure temperature and repeat if necessary. b. To LOWER water temperature, simply turn knob one notch counterclockwise to next lower number on dial. HINT: To measure water temperature accurately, remove the spray-head for a solid water stream. 4. WATER FLOW RATE ADJUSTMENT Locate adjustment screw on valve (as show here). Using an Allen Key or a flat screwdriver, rotate . turn at a time, Clockwise (CW) to decrease water flow rate or Counter-Clockwise (CCW) to increase water flow rate. Check water flow output after each . turn. The SINGLE DISPENSE VALVE is factory adjusted to dispense 0.6 oz./sec. of water during the brew cycle (spray duration). The DOUBLE/ DILUTION DISPENSE VALVE is factory adjusted, on both sides, to dispense 0.22 oz./sec of water during dilution cycle. SPECIAL COMPONENTS TEST 1) CHECK DISPENSE VALVES FOR LIME BUILD-UP (Located inside top cabin) Drain the water tank to just below the level of the Dispense Valves. Remove the Valves and clean. You can take these valves apart by hand as shown. Replace the assembly as needed. Replace the valve into the tank and refill tank. 2) WATER INLET VALVE (SOLENOID) TEST (Located inside bottom cabin) Turn power off. If the water level rises inside the tank, and shoots out of the overflow, the Water Inlet Valve is leaking. Disconnect wires from the Water Inlet Valve coil and connect a 2 wire line cord to the terminals. Plug it into a 115V outlet. If water flows in and stops when you pull it out, the Valve is working fine. Repeat this test a few times. The problem may be in the Probe. If the water does not flow in when the cord is plugged into an electrical outlet, the Solenoid coil may be damaged, opened or the valve may have an obstruction preventing the water from flowing in. Clean or replace it. A Check Valve is installed to prevent backflow. To check proper function of Check Valve, disconnect water line from the Check Valve, check for dripping from the disconnected end of the Check Valve. If it leaks, replace it. Water inlet Valve max. flow rate is 1.3 gal/min. 3) WATER LEVEL PROBE TEST (Located on tank top, inside top cabin) If there is a lack of water, you will get an uneven flow. Check the probe as follows: Turn on the power and water supply. Check inside the tank to make sure the water is not touching the Probe. Pull the wire and terminal out of the Probe rod. If water starts flowing into the tank, the Probe may be grounded, due to excessive liming. Check with Ohm meter. Clean or replace. 4) SOLID STATE WATER LEVEL CONTROL BOARD a) Make sure there is power input to the board at the terminals 2 & 3. Your voltmeter should read 115 volts. It should read the same at terminals 1 & 3. This is the output power to electrify the coil of the solenoid valve to open it. The lack of voltage at terminals 2 & 4 will indicate that the water level board is not working properly. b) Make sure all wire connections to the board are tight. c) The grounding plate at the top, in the back of the board, should be securely grounded. The board will not work, or will work erratically, if it is not grounded properly. If after this, the board is still failing to open the water inlet valve, then replace it. 7 N LI GROUND TERMINAL L398A - 120V L399A - 240V TO PROBE TO SOLENOID GROUNDING PLATE IN BACK OF THE BOARD TROUBLESHOOTING GUIDE WARNING: To reduce the risk of electrical shock unplug the dispenser power cord before repairing or replacing any ...
