LEAKING- 1.1.0 ISOLATE FOR HIGH LOADING PRESSURE
ENSURING the water is on, this procedure checks if VERY Loading Pressure may be causing a leak!
a)
ENSURING
the Loading Pressure gauge (yellow connector) reads 0 psi before inserting it,
SLAM
*
it
into the red Acetate/Acid rinse port.
b)
IMPORTANT!
To avoid error read parts c AND d BEFORE performing them!
c) Turn the machine on. When “Press CONFIRM For Service Mode” appears press ‘CONFIRM’.
d) Figure right, WHEN “System Initialization” reaches 90% does
the gauge EXCEED 30 psi OR ‘peg’ the gauge’s needle i.e.
much more than 30 psi?
Yes
Pressure more than 30 psi! Turn the machine OFF then see procedure number
(page 568).
No Pressure less than 30 psi! With the Main Service Mode menu REMAINING up, allow two (2)
FULL minutes OR until if an active leak reoccurs. TWO (2) possible scenarios 1) or 2) below:
1)
IF (and ONLY if) a leak DOES NOT reoccur:
A possible Secondary Side Leak. See
page 558
2)
IF leak reoccurs:
Listed under
PRIMARY SIDE LEAK
(below) are TWELVE (12) possible
scenarios (not inclusive):
PRIMARY SIDE LEAK:
Proceed according to where the leak is seen:
1)
Figure right, IF from Loading Pressure Valve #65:
Tighten
the Valve’s Phillips screws. If the leak
continues replace Valve #65.
2)
IF from the Heat
Exchanger BODY:
Proceed to page
3)
IF from the Heat
Exchanger’s TUBING:
A)
Secure the tubing with tie
wraps;
B)
Check Inlet Water Pressure Regulator per
the CALIBRATION PROCEDURES;
C)
Leaving the
gauge installed, turn the machine off and allow twenty
(20) minutes. If pressure exceeds 22 psi then
Regulator #61
*
may be bad.
*
To LOCATE #61 refer to
(page 557).
4)
Figure right, IF from a RINSE PORT:
Insert a dull
probe into the port to move the poppet valve back
and forth several times. If the leak continues replace
the rinse port.
