Disconnect power to the unit before servicing. Follow all lock out/tag out procedures established by the user. Verify all
power is off to the unit before performing any work.
Failure to comply could result in serious injury, death or damage to the equipment.
!
WARNING:
Water and CO2to the system must be turned off and the system depressurized prior to performing this service.
Failure to comply could result in serious injury, death or damage to the equipment.
1. Remove the upper front panel which is secured to the cabinet by “hooks” that fit into slots on the cabinet
front flange. Lift up on the panel right and left sides to disengage the hooks from the slots and then rotate
the panel downward and forward to remove from the cabinet. Disconnect the (3) electrical harnesses at the
rear of the front panel.
2. Remove the lower front splash panel (2 screws).
3. Locate the CO2 supply line (1/4 beverage tubing) to the carbonator tank located on the right side of the unit
above the coldplate (see Figure 1). Cut this line in an area that will be accessible for future servicing and
install the CO2 pressure switch with the fittings provided in the kit (see Figure 3).
4. Refer to Figure 2 for installing the CO2indicator light on the upper front panel. Remove the lid and straw
holder by loosening (3) screws at the “key-holes” and lifting up to clear the screw heads. Remove the lower
front ice portion control enclosure (4 screws) and disconnect the electrical harnesses as needed for
reworking the enclosure. Locate and drill a 1/2 in. diameter hole in the enclosure as shown in Figure 2 for
the indicator light. Insert the light from the front and “snap” into the mounting hole.

5. Refer to the wiring detail of Figure 4 to complete the electrical hook-up of the indicator light to the pressure
switch and the 24V beverage transformer power source.
6. Route the electrical wires to the CO2pressure switch behind the beverage panel with the harnesses from
the unit’s electrical control box. Remove the (6) screws securing the beverage panel to the cabinet. The
panel can now be pulled down to provide access for routing the pressure switch wires. Secure the wiring
with the plastic cable ties provided in the kit to avoid “pinching” (cutting) the wire insulation when the panels
are assembled to the cabinet.
7. Connect electrical power to the unit. Before opening the water and CO2supply valves to the beverage sys-
tem, verify that the CO2indicator light is on. The indicator light should go off when the CO2supply valve is
opened.
8. Check for proper operation of the ice portion control system and the beverage system. Refer to the opera-
tion instructional label located on the upper front panel and the owners manual. The unit is now ready for
operation.
