Troubleshooting your Cold Pro Nitro™ System
Problem
Cause
Solution
Not enough or too
much foam
The gas needle valve is not set up
properly.
Follow instructions in the
“Changing the Gas Level” section
on page 7. The needle valve has
a default setup of 1 mm with a
tolerance of +/- 0.25
The flowrate of the coffee and
the gas have to be adjusted to
coordinate together. If a change
of flowrate occurs through
change of the flowrate disc (9 or
10), the gas flowrate has to be
re-adjusted.
Follow instructions in the
“Changing the Gas Level” section
on page 7. The needle valve has
a default setup of 1 mm with a
tolerance of +/- 0.25
A change in the foaming behavior
can also be affected through
a flowrate reduction due to
clogging of the filter adapter (19)
or the tap jet-nozzle (3).
Check all filters or strainers
and remove any particles in it.
Unscrew the tap nozzle (3) and
check for particles lodged in the
strainer (8).
If there is too much foam sud-
denly, the dispenser might suck
air in via the product intake line
(11).
Check if all connections
between the dispenser and
coffee container are sealed
well. Sometimes the push-in
connection system causes air
leaks that need to be removed.
Dispensed coffee
is not cold enough
No electrical power or
temperature control (5) is turned
off.
Check the dispenser’s electrical
connection.For maximum
cooling, turn the temperature
control (5) clockwise to the 7
o’clock position.
The temperature can be adjusted
on the temperature control (5)
on the front panel. The target
dispense temperature at max
setup is
41° F
(5° C) (+/- 1.8° F
or 1° C) to
62° F
(17° C).
In case
of heavy tapping operation or a
warm coffee input temperature,
this temperature might not be
achieved.
If the cooling capacity of the
device is not strong enough, you
will need to increase the cooling
capacity.
Possible solutions for this are
described a the top of page 8.
