NW- 2.0.1 VALVE ERROR = 0 / ISOLATE INLET WATER PRESSURE
a) Leaving the machine in a program, TURN THE WATER OFF!
b) A psi pressure gauge is required. ENSURE it reads 0 psi before installing it!
c) Per the Figure below, tee the gauge into Inlet Pressure Regulator #61.
Figure 30 – Hydraulics Top View
d) TURN THE WATER ON!
e) WARNING! Do not use a plastic clamp in part e as this will cause error!
f) Using METAL PLIERS, tightly clamp the tubing between the gauge and the Heat Exchanger at the
location shown the Figure above. TWO (2) possible scenarios
1) IF the gauge = 18 psi or more: Remove the pliers then proceed to
page 162, procedure
number NW- 3.0.0
2) IF the gauge = less than 18 psi: ENSURING the water was on prior to checking pressure, remove
the pliers then see procedure number NW- 2.0.2 (page 160).
NW- 2.0.2 ISOLATE INCOMING WATER
a) TURN THE WATER OFF!
b) This procedure requires a 1000 ml (or larger) graduated cylinder.
c) Reproduce the conditions when the “No Water” occurred. For
example, multiple machines running attached to the same
PORTABLE RO, filling the bicarbonate tank, etc.
d) Figure right, at the rear of the machine, remove the (TOP)
Incoming Water tubing!
