PLUMBING INFORMATION A 3/8" pipe thread X 3/8" compression 90º elbow is supplied with this brewer for water line connection. Use 3/8" O.D. copper tubing to connect water to the machine. We recommend using a good water filter in the line before entering the brewer. Some type of water strainer MUST be used to obtain a trouble-free operation. The removable top back panel of the brewer has two 1/4 dia. screws to facilitate mounting the water filter. CAUTION: DO NOT connect this brewer to hot water.
INSTRUCTIONS FOR CONNECTING TO INTERLOCK GRINDER 1. Place grinder near brewer. 2. With the top cover removed, take out the empty strain relief from hole labeled INTERLOCK in back of brewer. Pass the end of the grinder interlock cable through this hole. On single head brewers plug the cable directly into timer WC-642 or into the interlock cable (if present). On dual head brewers plug the interlock cable into the timer interlock cable. 3. Place strain relief onto cable outside of brewer.
OPERATING THE INTERLOCK SYSTEM Make sure that the Set-up Instructions, are complete before attempting to operate the Interlock System. 1 . Push the Brew Cone into Place on the Grinder. Decide on Regular or Decaf. Push 12, 24 or 36 Cup Switch. Coffee Will Start to Grind. 2 . When the Grinder Stops, Slide the Brew Cone into the Rails on the Brewer. On the 312 you may use either side, as both are interlocked. 3 . Push the Lighted Brew Switch with the Lighted Indicator. Coffee Will Start to Brew.
BY-PASS FLOW OPERATION These brewers are set at the factory to brew 12, 24 or 36 cups of coffee. The 36 cup brew cycle has a by-pass valve that will by-pass up to 40% of the water around the coffee grounds. If you desire to change this setting for any reason, you may do so by adjusting the by-pass valve (part no. WC-844) on the Gemini 312IL (item no. 57*) and on the Gemini 300IL (item no. 56) BY-PASS FLOW ADJUSTMENT 1. Place satellite, without cover, on the warmer deck. 2.
COFFEE REQUIREMENTS TYPE These Gemini brewers are designed to brew any type of ground coffee. Instant or concentrated liquid coffee is not recommended. Before attempting to use these coffee products, consult your coffee provider. QUANTITY Because so many different grinds of coffee are available today, you should consult your coffee company. Generally 6 to 8 ounces are used to brew 1½ gallons (36 cups). Referring to the by-pass flow adjustment section will show you how to adjust the brew to your tastes.
POWER DISCONNECT Before removing any panels or starting any repairs, turn off power running to the brewer, from the main circuit breaker panel. The toggle switch, in back of the coffee brewer, turns on the power up to the contactor only. One half of this relay, (part no. WC-400R) and one line to the heating elements remain electrified. With the toggle switch turned off, the coffee brewer is inoperable.
PROBLEM: NO WATER IS ENTERING THE HEATING TANK TANK INLET VALVE TEST TURN POWER OFF. Disconnect wires from the water inlet valve coil and connect a two wire lamp cord to the terminals. Plug it into a 115 volt outlet. This will activate the coil. Water should flow into the tank when you plug it in and stop when you pull out the plug. If it does, the valve is working normally. If the water inlet valve passes this test, the problem may be with the probe or water level control board.
B. Disconnect ORANGE wire from T4 of water level board and check for continuity from the terminal of this wire to the tip of the probe inside the heating tank. If there is no continuity, find the point where continuity is broken and correct it. C. If the tank is full but water continues to flow in, check for voltage at the water inlet valve coil. If there is voltage, the water level control board is not working properly.
If you do not read 110 to 120V the contactor coil may be burned, remaining open and interrupting the flow of current to heating elements. The contactor may need to be replaced. PROBLEM: WATER IS NOT HOT ENOUGH Components to test: 1. Heating Elements . . . . . . . . . . . . . . . . 2. Primary Thermostat . . . . . . . . . . . . . . Part No. WC-906 Part No. WC-517 A.
(through terminals 4B and 5B of the switch). With the switch in the ON position, check for voltage between any of the above mentioned terminals and any neutral terminal (WHITE wire). You should read 110 to 120 volts. If not, the ON/OFF switch is defective. Replace it. C. Pushing any of the 12 cup, 24 cup, or 36 cup brew switches will open the dump valve, sending hot water to the sprayhead. If the valve fails to open; check the coil for continuity.
