Mixing - Infusion Manifold; Dispense Manifold - Cornelius NITROPRO MINI Service And Preventative Maintenance Manual

6.0 COMPONENT REPLACEMENT (Cont.)
6.4.1 Air Pressure Regulator (Cont.)
5) Connect the new regulator to the air hoses.
6) Reinstall the regulator in reverse order.
7) Confirm operation and adjust as required.

6.4.2 Mixing - Infusion Manifold

1) On the underside of the assembly baseplate,
remove the screws securing the mixing-infu-
sion manifolds (Fig. 6-3).
2) Use tape and a marker to label the five hoses.
3) Loosen the C-plate retainer screws where the
four hoses connect to the manifold (Fig. 6-4).
Figure 6-4 - Mixing Manifold Hose Fittings Removal
4) Move a retainer plate aside and rotate the hose
fitting back and forth while withdrawing it
from the manifold. Remove the four fittings.
Check/replace their o-rings as needed.
5) Carefully remove the threaded, hose-nipple fit-
ting from the infuser manifold by first remov-
ing the hose clamp using side cutters or the
recommended Oetiker HIP 2800 Es crimping/
cutting tool (see Fig. 6-5). Cut the clamp open.
CAUTION!
Be careful to avoid damaging the tubing
when removing the hose clamp.

6) Remove the hose and unscrew the threaded,
hose-nipple fitting. Clean off the Teflon tape
and apply new tape (or use an NSF 61 pipe-
sealing dope, such as T Plus 2 by Rector Seal).
7) Remove the mixing-infusion manifold and place
the new one in the mixing-dispensing assem-
bly.
8) Reinstall the hoses in reverse order. When
tightening the threaded, hose-nipple fitting in
the infuser manifold, tighten it finger tight and
then rotate it 2 to 3 turns to prevent leakage.
Use the Oetiker crimping tool to install the
hose clamp on the hose-nipple fitting.
9) Secure the manifold assembly to the baseplate
by reinstalling the underside screws.
10) Reinstall the mixing-dispensing assembly in
the cabinet, operate the dispenser and check
all the manifold hose connections for leaks.

6.4.3 Dispense Manifold

1) Remove the assembly-underside screws that
secure the manifold (Fig. 6-6) to the baseplate.
Figure 6-6 - Dispense Manifold Assembly
2) Unplug the two solenoid wires and disconnect
the hose from its port.
