4. CONNECTION FOR PLAIN WATER PRODUCT
4.1
PROCEDURE
If a plain water product is desired, make sure the center water module is connected to the center
plug (marked “WATER”) on the PCB. Then follow the procedure in Section 5.2 which follows.
5. SETTING MEMBRANE SWITCH AND PLUMBING CONFIGURATIONS
5.1
GENERAL
Depending on the number of finished products available (4 or 5), unused switches on the right side
of the membrane switch panel can be configured to operate a common syrup module (see
Figure 1). The center column of switches is used for Portion Control, which is standard on all units
(see Section 5.3). There are no unused switches on the left side in any configuration. The small
button on the top left will always dispense soda, and the large button on the bottom left will always
dispense plain water.

Membrane Switch Panel Configuration
Figure 1
To configure a common module to two switches, place the jumper on the PCB at the location
indicated and plug the syrup module into the respective connector as shown by the shaded squares
in Figure 2. For a unit where three modules are plumbed to a single nozzle, no jumper is used. The
module connectors on the PCB correspond to the switches on the membrane panel as shown above
when no jumpers are used.
