A

The water in the heating tank A, is maintained at the same level at all times by a sensor called the water level probe B. This controls the water inlet valve C.

When the brew switch is pushed, a brew cycle

NOTICE

This brewer must be installed by a professional licensed technician and must comply with all local electrical, mechanical and plumbing codes having jusrisdiction. Wilbur Curtis Company will not accept any responsibility if these conditions are not met. This machine must be used for it's intended purpose and the function for which it was designed.

SETUP INSTRUCTIONS

1. Locate a position for the Gemini 120A on a firm and level, counter top.

2. Remove the top cover of the brewer and lid from the heating tank. Hand fill the tank until the water level is approximately two (2) inches below the probe tip.

3. A 1/4" female flare fitting is required for water supply. Connect the water line to the inlet valve fitting and turn on the water.

4. With the top cover removed, turn thermostat stem clockwise until it stops.

5. Plug the unit into a power supply outlet and turn toggle switch on. Turn ON/OFF switch to ON position. Make sure water is flowing into the heating tank. Filling should stop when the water level reaches the probe tip. When this is verified, replace both tank lid and top cover to the machine.

6. Allow 15 to 20 minutes for the water in the tank to reach brewing temperature. The

BREW READY light will come on when it reaches the correct temperat ure.

GEMINI 120A

ADJUSTMENT INSTRUCTIONS FOR TIMER WC-603RDS

The Gemini 120A now has a new timer which was introduced starting from serial number

14866. It is a new, improved version of the previous WC-603 RD timer. The wiring on this has remained exactly as on the older versions to make retrofitting easier.

The timer is mounted inside the upper compartment with the brew selector knob protruding from the center of the front panel (see illustration, left). The brewer is designed to brew 24 cups (one gallon maximum). Adjustment of the timer is made on the timer calibration dial. The knob indicator must be set at the 480 second mark on the dial. On the front panel, the brew selector switch should be at

2. This setting will deliver one gallon of water

(brew 24 cups) per brew cycle. To brew 12 cups, simply turn the brew selector knob to 1.

If finer adjustments are needed, rotate timer knob to the right to increase the brew time, rotate to the left to decrease the brewing time.

CARE AND MAINTENANCE OF THE GEMINI 120A

Regular cleaning and preventive maintenance is essential in keeping your Gemini Coffee Brewer looking and working like new.

WARNING Do not use cleansers, liquids, bleaches, or powder that contain chlorine.

These products cause corrosion and pitting on stainless steel and will void your warranty.

PREVENTIVE MAINTENANCE:

1. Remove the sprayhead from the Gemini 120A and clean once a week or more often in heavy lime areas.

2. Clean the faucet seat cups twice a week and replace when they are cracked or leaking.

3. Periodic temperature checks or adjustment of thermostat by authorized personnel.

CLEANING

To maintain optimum coffee flavor, the Gem 3 Satellite should be cleaned daily after the last batch of coffee is used. We recommend the use of urn cleaning powder or Scotch Bright pads for cleaning inside the coffee container.

The outside of the brewer and Satellite should be cleaned with a soft cloth and stainless steel polish only, to prevent scratching the surface.

Deliming of the heating tank should be done every six (6) months; more often in heavy lime areas.

TROUBLE SHOOTING

PROBLEM: WATER DOES NOT FLOW INTO HEATING TANK

POSSIBLE CAUSE

1. Water line turned off or filter clogged up.

SOLUTION

Open the water line and make sure water flows to the brewer.

2. Water inlet valve coil burned out

3. Grounded probe (item

#12)

4. Defective or burned out water level control board

(item #3)

Turn off brewer. Disconnect wires from water inlet coil terminals and connect a power cord to the terminals. Plug cord into a 110v outlet and verify that water flow when plugged in and stops when cord is disconnected. If valve does not respond to this test, replace the valve.

When water in the heating tank is below the probe tip, yet water is not refilling, pull the wire off the probe terminal. If water starts flowing into the tank, find ground, clean or replace the probe.

Pull the wire from the probe terminal. With a volt meter, check the voltage at the water inlet coil terminals. This should read 110 to 115 volts. If no voltage is present, check the water level control board.

Make sure that the back of the board is grounded securely to the mounting bracket. Check for loose wire connections. Replace board.

PROBLEM: WATER IN HEATING TANK OVERFLOWING

POSSIBLE CAUSE

5. Defective water inlet valve (item #28)

SOLUTION

Turn power off and observe the water level in the heating tank. If water continues to flow in, clean or replace the valve.

6. Probe limed up (item #12)

7. Loose or ungrounded water level control board

(item #3)

Pull wire off from probe terminal. Touch the water tank shell with the terminal at the end of this wire. If water stops flowing, clean or replace the probe.

If probe is okay, check the water level control board. The water level control board must be securely grounded. Check for loose connections. Check for voltage at the inlet valve terminals. Replace board.

PROBLEM: WATER IN TANK DOES NOT GET HOT OR WATER TEMPERATURE TOO LOW

POSSIBLE CAUSE

SOLUTION

8. Thermostat is off (item #31) Check the thermostat (item #31) to make sure it is in the ON position. Turn the thermostat stem clockwise until it stops.

9. Burned out heating

element.

Check element for continuity and/or check with clamp ammeter. This should show a reading of approximately 15 amps. If no power is going through element, replace it.

GEMINI 120A

PROBLEM: WATER IN TANK DOES NOT GET HOT OR WATER TEMPERATURE TOO LOW

SOLUTION

POSSIBLE CAUSE

10. Defective thermostat Thermostat may be cutting off before the water temperature reaches operating temperature. Do not try to reset the thermostat. Replace it.

PROBLEM: WATER NOT FLOWING FROM SPRAYHEAD.

POSSIBLE CAUSE

11. Water level is too low

in heating tank

SOLUTION

Check water level in tank. If water is not flowing into the tank, review steps 1 thru 4, previous page.

12. Defective brew switch

(item #41)

Check the continuity between terminals 5B and 4B when the BREW switch is pressed. If there is no continuity, replace the switch.

13. Defective timer (item #2).

14. Burned out dump valve coil (item #34)

Make sure the timer is receiving 110 to 120 volts. You can verify this by taking a reading with your meter at the end of the YELLOW wire on terminal 5B of the ON/OFF switch and at terminal A of the timer.

When the timer is activated by the brew switch, you should read

110 to 120 volts across terminals 6 and A of the timer. The RED wire on terminal 6 supplies power to open the dump valve. If no voltage is present, replace the timer.

If the timer works when the brew switch is pressed, then check the dump valve using a voltmeter on the terminals. If it shows 110 to

120 volts but no water flows through the valve, clean out the valve or replace the coil.
