Problem Probable Cause Remedy
DISPENSER IS BRIXING
OUT TOO HIGH. (Cont.)
Low viscosity or highly
concentrated concentrate.
Example 11 to 1 ratio.
Locate the pump switches grouped
behind the front splash panel. They
are marked SPEED SWITCH with
the corresponding valve number.
Placing the switch in the low position
slows down the concentrate pumping
rate requiring less water to brix.
DISPENSER IS BRIXING
OUT TOO LOW.
Supply water pressure is too
high.
Defective or improperly
regulating flow control .
Speed switch in the low
position.
Air leak in the concentrate
suction line.
Worn concentrate pump
tubing.
Defective poppet valve and or
spring.
Water pressure has a high limit of
100 psi/ 7 bar or over. Place regulator
in supply line to bring pressure down
to 4 bar/ 50 psi flowing.
High water pressure will cause the
flow control not to regulate properly.
If the problem exists after the
pressure has been reduced to 50 psig/
4 bar, the flow control maybe
defective.. Disassemble and check the
spool and sleeve function and the
compensating spring . Replace parts
as required.
Pump speed switch is in the low
position. Move switch to high
increasing the pumping rate of the
concentrate.
Check that the concentrate line
connection is secured tightly to the
dispenser with the proper gaskets.
Check the connector at the
concentrate source to be sure it is
properly attached.
Remove the front half of the
concentrate pump and inspect the
tubing . Worn or stretched tubing will
decrease the amount of concentrate
pumped. After 1 year tubing should
be replaced.
Disassemble the right side of the
valve which contains the syrup
poppet assembly. Be sure the valve is
not binding, free of debris, return
spring is actuating and the diaphragm
is not torn or punctured.
