FUNCTION OF THE GEMINI
The water in the heating tank A, is maintained
at the same level at all times by a sensor
F
12
called the water level probe B. This controls
the water inlet valve C.
H
C
When the brew switch is pushed, a brew cycle
starts: The dump valve D, is opened by the
12

brew timer E, allowing hot water to be sprayed
over the ground coffee for a specific time
period .
Brewed coffee then pours from the brew cone

The hot water faucet G, dispenses hot water
for tea, instant beverages, or soups and can
be used at any time without interrupting the brew cycle. A warmer element, H, keeps the coffee in
the Satellite at the proper temperature.

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 temperature.

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.

GEMINI 120A
TROUBLE SHOOTING
PROBLEM: WATER DOES NOT FLOW INTO HEATING TANK
SOLUTION
POSSIBLE CAUSE
1. Water line turned off or
filter clogged up.
Open the water line and make sure water flows to the brewer.
2. Water inlet valve coil
burned out
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.
3. Grounded probe (item
#12)
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.
4. Defective or burned out
water level control board
(item #3)
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
SOLUTION
5. Defective water inlet
valve (item #28)
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)
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.
7. Loose or ungrounded
water level control board
(item #3)
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
SOLUTION
POSSIBLE CAUSE
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.
-3-
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
SOLUTION
11. Water level is too low
in heating tank
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).
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.
14. Burned out dump valve
coil (item #34)
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.
