GEMINI 200R COFFEE BREWING SYSTEM
Read and follow Setup Instructions before attempting to use this brewer. This manual should
cover most questions you may have about the Gemini 200R. However, if you need additional
information, you can call our factory Technical Service Department at (323) 269-8121.
When you encounter index numbers in parentheses, following parts mentioned, they refer to the
index numbers on the parts list, pages 7 to 10.
SETUP INSTRUCTIONS
1. Carefully unpack shipping carton. Check for any damage.
2. Attach the four adjustable legs, threading them into tapped holes underneath the brewer.
Level the machine.
3. Rinse out the brew cone and satellite with water.
4. Hookup electrical and plumbing to comply with all local building codes.
A. Remove the panel in back of the machine to gain access to the wiring for electrical
hook-up (see fig. 1 to wire power to the brewer).
B. Thread the 3/8" compression fitting into the water inlet valve behind the brewer. Run a
3/8" copper tubing water line with a 3/8" flare nut to this fitting. It is recommended
that a water shut off valve be installed on the incoming water line to the brewer.
IMPORTANT: Brewer must be connected to COLD water line. Water inlet valves are not
rated for hot water.
5. Remove the top cover (1) by loosening four screws.
6. Make sure the thermostat (56) is turned OFF (knob turned all the way counterclockwise),
otherwise the heating elements will be damaged if the tank is not filled with water.
7. Open water supply valve.
8. Switch power on at the power switch (45) behind the brewer. This will activate the components in the brewer. Water will now automatically start filling the heating tank and will
stop once the water level reaches the probe tip (78).
9. Turn the thermostat ON, by turning knob fully clockwise. Replace top cover.
10. Turn ON the ON/OFF switch (30), located on the front panel.
11. Place Satellite server on warmer deck.
12. Push ON warmer switch (28) to preheat the Satellite server. Before brewing coffee, the
Satellite servers must be preheated for ten minutes.
IMPORTANT: Never brew coffee into a cold Satellite. Doing so will result in a lower coffee
serving temperature.
13. Allow ten minutes for the water in the tank to reach full temperature. After the initial heat
up, temperature recovery is very rapid. You can brew up to two 24-cup cycles before you
must allow time for temperature recovery between brews.

FUNCTION OF THE GEMINI
The water in the hot water tank E, is maintained at
the same level at all times by a sensor called the
water level probe A. This controls the water inlet
valve G.
When a brew switch is pushed, the brew cycle is
started: The dump valve B, is opened by the brew
timer, allowing hot water to be sprayed over the
ground coffee in the brew basket C.
The hot water valve F, dispenses hot water for
tea, instant beverages, or soups.
A warmer element, H, keeps the coffee in the
Satellite at the proper temperature.

GEMINI 200R TROUBLE SHOOTING
The Gemini 200R is a simple machine to service. This Trouble Shooting guide will cover most
questions you may have about the Gemini 200R. If you find that you cannot remedy a problem
on your machine, you may call our factory service department at (323) 269-8121.
Index numbers in parentheses refer to index numbers on the Parts List, pages 7 to 10.
IMPORTANT - ANY SERVICE DONE ON THESE UNITS MUST BE PERFORMED BY
QUALIFIED SERVICE TECHNICIANS.
!
WARNING TO HELP AVOID PERSONAL INJUR Y
Caution must be taken to avoid electrical shock. Be sure power to the brewer is OFF before
removing components.
The following steps will also involve working with hot water . Scalding may occur if care is not
taken against spilling. Surfaces may be hot.
1. PROBLEM: Heating tank is not filling.
POSSIBLE CAUSE
Water not flowing into
the coffee brewer.
Water filter is clogged.
Grounded probe (78).
Disconnect the water line from the inlet valve (31) and check to see
how much water pressure there is. Reconnect the water line.
Your filter cartridge may need replacing.
Whenever the water level in the tank drops below the probe tip, the
water inlet valve should open to fill the tank. If the water level is
too low, check to see if the probe is grounded. Pull wire terminal
off the terminal on the probe. If water flows into the tank, this
indicates that the probe has shorted somewhere. Locate the short
and correct it. Wrap probe wire with Teflon tape if there is an
indication of excessive condensation. Unscrew the probe and
polish it with sand paper. Leave 1/8" of tip exposed.
SOLUTION
Water inlet valve coil
burned out.
Defective Liquid Level
Control board
(L.L.C.)(54).
Turn off power to the brewer at the toggle switch, (45). Disconnect
wires at the inlet valve coil. Connect a lamp cord to the coil terminals and plug into a 120V outlet. Water should flow out of valve. If
valve does not respond, clean out or replace valve.
If tests indicate that both the probe and water inlet valve are functioning correctly but low water condition persists; check the operation of the liquid level control board.
Measure voltage at the input terminals T2 & T3 of the L.L.C.. Your
voltmeter should read approximately 115 volts. It should also read
115 volts at the output terminals T1 & T3 (this output supplies
power to the valve coil). Lacking voltage at T1 & T3 terminals will
indicate that the L.L.C. is malfunctioning. All wire connections to
the board should be tight. Make sure there is contact between the
grounding plate on the back side of the L.L.C. and it's mounting
bracket. If these tests check out and the board is still inoperative,
replace the L.L.C..

GEMINI 200R TROUBLE SHOOTING, CONTINUED
CAUTION Do not turn water supply off and leave brewer on. The coil on the water
inlet valve will be damaged.
2. PROBLEM: Water overflowing heating tank.
POSSIBLE CAUSE
Torn diaphragm or lime
build up in water inlet
valve seat.
Lime build up on the water
level probe (78).
A break in the probe circuit.
Defective L.L.C. Board
(54).
SOLUTION
Remove the top cover of the heating tank and check the water
level. Switch off the power using the toggle switch, (45), behind the machine. If water continues to flow into the tank, the
valve is leaking.
Clean, rebuild or replace the valve (valve repair kit #WC-3765).
Pull off wire with terminal from water level probe. Touch the
steel body of heating tank with terminal end of wire. If water
flow stops, this is an indication that the probe is probably limed
up or has lost it's continuity to the solid state L.L.C. board.
Clean probe or look for a break in the circuit and repair it.
Make sure there is contact between the grounding plate on the
back side of the L.L.C. board and it's mounting bracket. All wire
connections to the board should be tight. Measure voltage at
the input terminals T2 & T3 of the L.L.C. board. Your voltmeter
should read approximately 115 volts. It should also read 115
volts at the output terminals T1 & T3 (this output supplies
power to the valve coil). Lacking voltage at these terminals will
indicate that the L.L.C. is malfunctioning. If these tests check
out and the board is still inoperative, replace the L.L.C. board.
3. PROBLEM: Water temperature in the heating tank is too low or cold.
POSSIBLE CAUSE
Thermostat (56) is turned
off.
Burned out heating element (68).
Check to see that the thermostat is turned on. Twist the stem
clockwise as far as it will go.
Read current with a clamp ammeter on one of the two 10 gauge
wires connected to the element. Turn on the machine. The
meter should read around 16 amperes.
If you cannot get a reading, using a voltmeter, check for voltage
across the heating element terminals. If there is approximately
220 volts, the element is burned out.
SOLUTION

Page 8
GEMINI 200R TROUBLE SHOOTING, CONTINUED
4. PROBLEM: Water does not pour from the sprayhead when the brew switch is pushed.
POSSIBLE CAUSE
Insufficient water in the
heating tank.
Defective timer (49).
Dump valve coil (37) is
burnt out.
SOLUTION
Check the water level in the tank. If water is not flowing or is
flowing too slowly, check the automatic refill system (refer to
step 1 of Trouble Shooting).
The power input to the timer is at terminals 1 and 5. Voltage
between these terminals should be approximately 115 volts. If
you cannot get a reading at these terminals, check the ON/OFF
switch (30). When this switch is pressed to the ON position,
you should read approximately 115V between terminals 5B and
3A. The same voltage should show at terminals 2 and 5 of the
timer. Lack of voltage at these terminals will show that the
timer is not opening the dump valve. Replace the timer.
If the timer is working, check the coil on the dump valve. If
there is voltage, you should read approximately 115 volts between the terminals. If there is voltage, the coil may be burned.
Replace coil.
Check also for clogging or lime deposits causing the valve to
lock up. Clean or replace valve.
TANK LID
This brewer is equipped with a new tank lid design, part no. WC-5661. This new lid does not require
the silicone gasket that had been used in previous brewers.
1. When replacing or reinstalling this lid, make sure the tank lipis
perfectly round and free from any buildup.
2. The lid must sit in a level position.
3. Make sure that when installing the lid, the bracket or screws do not
