IR OMPRESSOR RESSURE ERIFICATION
This procedure is a measurement of the air pressure in the
air storage chamber to determine if the air pump is working
properly and shutting off when the pressure is approxi‐
mately 80 psi (552 kPa).
1) Shut off power to the Nitropro unit.
2) Inside the cabinet, disconnect the dispense‐assembly air
line from the back wall air inlet. Connect a 100 psi (689 kPa)
air pressure gauge with a quick‐connect fitting to the Air
Inlet line (Figure 5‐1).

3) Apply power to the unit.
4) Dispense a Nitro coffee drink or two to trigger air‐com‐
pressor operation.
5) Observe the pressure gauge.
6) The compressor should stop running at a reading of 75 to
85 psi (517 to 586 kPa). If the pressure is out of range, check
for leaks and check/replace the storage‐chamber pressure
switch.
