SERVICE (CONT.)
Liquid Autofill System
Location:
Located inside the right access cover are the Syrup
and water solenoid valves for each hopper. Some models
will have only syrup valves and lines.
NOTE: Refer to manufacturers instructions for all com-
ponents on the outside of the machine.
Proper Installation:
• The Brix pump should be placed as close to the con-
centrate supply as possible.
• The Brix pump mounting placement should be the
same level or slightly higher than the concentrate BIB.
• The sanitizing valve should be no more than 6” from
the brix pump.
• Insure ease of access to the brix pump and sanitize
valve for sanitizing procedure.
Test Procedure:
A water regulator is used to maintain pressure of
50 psi.
Check for voltage at the Syrup valve solenoid between
the WHT and RED wires for the right valve(s) or be-
tween the WHT and BLU wires for the left valve(s). The
reading should be: 100 vac for 100V machines, 120
vac for 120V machines, or 230 vac for 230V machines.
If voltage is not present as indicated, replace solenoid
valve(s).
Check for voltage at the Water valve solenoid between
the WHT and RED wires for the right valve(s) or between
the WHT and BLU wires for the left valve(s). The read-
ing should be: 100 vac for 100V machines, 120 vac for
120V machines, or 230 vac for 230V machines.
If voltage is not present as indicated, replace solenoid
valve(s).
Removal and replacement:
1. Shut off and disconnect the product and water
supply lines to the machine.
2. Remove the right side panel.
3. Disconnect the product inlet and outlet lines at the
solenoid.
4. Remove WHI and RED or BLU wires from solenoid
valve.
5. Replace the faulty solenoid valve with new valve.
6. Reconnect WHI and RED or BLU wires to solenoid
valve.
7. Reconnect the product inlet and outlet lines at the
solenoid.
8. Install the right side panel.
9. Turn on the water and product supply.
10. Inspect for leaks.
