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 clean-
ing 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.
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 com-
partment with the brew selector knob protrud-
ing from the center of the front panel (see
illustration, left). The brewer is designed to
brew 24 cups (one gallon maximum). Adjust-
ment of the timer is made on the timer cali-
bration 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.
