F- 1.0.6 ISOLATE LOADING PRESSURE
A) ENSURE the Loading Pressure gauge (yellow connector) reads 0 psi BEFORE installing it SLAM it
into the Acetate/Acid rinse port!
B) Loading Pressure may or may not cycle. TWO (2) possible scenarios:
1) IF cycling, possibly every nine (9) seconds: Pressure is ‘OKAY’ if it cycles to a PEAK of
somewhere between 23 and 27 AND a low of NEVER LESS than 11 psi. Watch both levels for
one (1) minute THEN see part C.
2) IF NOT cycling: Pressure is ‘OKAY’ if it STAYS between 23 and 27 psi. See part C.
C) TWO (2) possible scenarios:
1) IF (and ONLY if) pressure REMAINS ‘OKAY’: Leaving the gauge installed, see procedure
number F- 1.0.6.11 (page 31).
2) IF pressure is EVER NOT ‘OKAY’: Close the shunt door THEN proceed to
page 33, procedure
number F- 1.0.7.
F- 1.0.6.11 LOADING PRESSURE ‘OKAY’
Figure right, TWO (2) possible scenarios:
1) IF (and ONLY if) NOT equipped with a bibag
Connector: Proceed to page 38, procedure
number F- 2.0.0.
2) IF equipped with a bibag Connector: This
procedure checks Valve #101. If it is sticking
open bicarb is rapidly drawn! Perform parts a
AND b below:
a)
Leaving [Dialysate Flow] on, disconnect the Bicarb (blue) connector from the jug and allow
it to hang. DO NOT plug it into its rinse port!
b) Watch the Loading Pressure gauge for two (2) minutes! It may occasionally cycle below 15 psi but
is ‘OKAY’ if it PEAKS to between 23 and 27 psi. TWO (2) possible scenarios:
1) IF (and ONLY if) it PEAKS to between 23 and 27 psi! Reconnect to the bicarb jug THEN
proceed to page 38, procedure number F- 2.0.0
2) IF DROPS to and REMAINS less than 18 psi: See parts a THROUGH c next page:
