Troubleshooting
Below find a table with potential problems, its causes and solutions.
Problem
Cause
Solutions
1)
Not enough or
too much foam
a)
A change in the foaming behavior
can be caused through a flowrate
reduction due to clogging of the
filter adapter or the outlet jet-
nozzle.
Check your filter in the intake line and
remove any particles in it.
Unscrew the tap nozzle upper part and
check if particles have clogged the
strainers.
Unscrew the tap nozzle bottom part and
check if the disc hole is clogged with
particles.
b)
Also a flowrate increase can
create a liquid/gas mismatch and
lead to a poor dispensing result.
Check if the flowrate is around 600
ml/min. If it is significantly higher
something is wrong with the 2-hole disc.
Get in touch with CARBOTEK.
c)
If there is too much foam
suddenly the dispenser might suck
air in via the product intake line.
Check if all your connections between
dispenser and coffee container are sealed
well. Sometimes the John-Guest push-in
system causes air leaks that need to be
fixed. There must be no air bubbles
coming through the intake line together
with the product into the dispenser-
d)
Check the Nitro-ON/OFF toggle
switch.
Change the direction of the
Nitro-ON/OFF toggle SWITCH and try
again.
2)
Not cold enough
No electrical power or thermostat
knob is turned off.
Check if dispenser has electrical power
(does the air compressor run?)
For max cooling turn the thermostat knob
clockwise until 7 o’clock position.
The temperature can be adjusted on
the thermostat knob on the front
panel. The target dispense
temperature at max setup is
5 °C (+ /- 1 ° C).
In case of heavy series dispensing, or a
too high input temperature of the
coffee, these 5 °C might not be
achieved.
If the cooling capacity of the device is not
strong enough, you need to increase the
cooling capacity or precool your coffee.
Get in touch with CARBOTEK.
3)
Flowrate is too
fast or too slow.
The perforated disc, which is mounted
in the jet-nozzle outlet-spout (bottom
part), determines the dispense
flowrate.
The 2 hole disc provides a flowrate
of 0.6 l / min.
A 5 hole disc provides a flowrate
of 1.2 l / min. This is available optionally.
Put the suitable disc into the tap nozzle.
Be aware that a faster flowrate lowers
the cooling result at non-stop dispense.
