OVER- 3.0.0 CHECK INLET WATER PRESSURE (Slow Overflow)
This procedure uses a pressure (psi) gauge to check Inlet Water Pressure Regulator #61. Assure the
gauge reads 0 psi before installing it!
a) Assure incoming water (RO source) pressure is no greater than 105 psi.
b) IMPORTANT! Turn the water off. Referring to
Regulator #61.

IMPORTANT!
c) Turn the water on!
d) Place the machine into Dialysis program (remember to press the 'CONFIRM' key).
e) Normally pressure fluctuates between a maximum of no greater than 20 psi and to a minimum of no less
maximum
than 8 psi. Is the
Yes a) Loosen Regulator's #61's lock nut and turn the adjustment screw counterclockwise
until a maximum of between 18 and 20 psi is achieved. If pressure will not adjust
incoming water pressure is too high (greater than 105 psi) OR regulator #61 is bad.
b) Leaving the gauge installed, see procedure number
No a) Leaving the gauge installed, if pressure remains less than 10 psi ASSURE the water is
on!
b) See procedure number
