Over- 8.0.0 Isolate Inlet Water Pressure - Fresenius Medical Care 2008K2 Troubleshooting Manual

OVER- 8.0.0 ISOLATE INLET WATER PRESSURE

High inlet water pressure can damage a Heat Exchange!
IMPORTANT!
a) Turn the water OFF!
b) This procedure uses a psi pressure gauge. ENSURE it reads 0 psi before installing it!
c) Per the Figure below, install the gauge at Inlet Pressure Regulator #61.
IMPORTANT!
d) Turn the water ON!
Place the machine into RINSE!
e)
f) Allow one (1) minute then call debug screen 0 to
ENSURE Flow Error (Figure right) = 0 constant.
g) Pressure should be cycling to a maximum of between 18 and 20 psi?
Yes Maximum is between 18 and 20 psi! See procedure number
No Per the Figure above, A) Loosen Regulator's #61's lock nut. B) Can the center screw be
adjusted until a maximum of between 18 and 20 psi is achieved? NOTE: Counterclockwise
decreases pressure. TWO (2) possible scenarios:
1)
IF (and ONLY if) between 18 and 20 psi is achieved! See procedure number
OVER- 8.2.0
2)
IF between 18 and 20 psi CANNOT be achieved: TWO (2) possibilities: 1) Incoming
water pressure is more than 105 psi OR; 2) Bad Regulator #61. Regulator #61 can be
rebuilt (Rebuild kit, P/N 190934).
