LEAKING- 6.0.0 LOADING PRESSURE IS HIGH / ISOLATE VALVE#65 FOR DEBRIS
a)
With the machine OFF
, referring to
(page 556), turn Loading Pressure Valve’s
#65’s adjustment nut COUNTERCLOCKWISE to the point that it is almost all the way out i.e. maximum
number of threads showing!
b) Reconnect and tie wrap ALL ‘blown off’ tubing segments!
c) Read parts d and e BEFORE performing them!
d) Turn the machine on. When “Press CONFIRM for Service Mode” appears press ‘CONFIRM’. The screen
says “Machine in Service Mode”.
e) Keeping an eye on the gauge, When ‘System Initialization’ reaches 90% does pressure again EXCEED
30 psi OR ‘peg’ the gauge’s needle (i.e. much more than 30 psi!)?
Yes
Pressure exceeds 30 psi! See procedure number
No
Pressure less than 30 psi! Perform the Loading and Deaeration Pressure calibration per the
Calibration Procedures booklet!
LEAKING- 6.1.0 PRESSURE EXCEEDS 30 PSI
a) Turn the machine OFF
b) Remove Loading Pressure Valve #65* from the Hydrochamber. *To LOCATE Valve #65 refer to
105 A
(page 556)).
NOTE: There will be leakage but leave the water on!
c) Debris
that may be restricting Valve #65’s Hydrochamber return port.
NOTE:
Referring to the 2008K/K
2
Flow Diagram, debris can be ANYWHERE between Deaeration Pump’s #20 output and Loading Pressure
Valve #65. Is debris located?
Yes
Debris
*
(page 568).
No a) Reinstall Valve #65
b) Return to Service Mode.
c) Attempt to set Loading Pressure maximum to between 23 and 25 psi. If maximum pressure
will not adjust below 30 psi, TWO (2) possibilities:
1)
Debris that was not located or
reoccurred OR;
2)
Bad Loading Pressure Valve #65.
* Possible debris sources: 1)
Excessive O-ring lubrication;
2)
Inadequate acid clean cycles (i.e.
excessive bicarbonate precipitate);
3)
Inadequately filtered incoming water; 4) Possible degrading
Deaeration Pump head gears.
LEAKING- 6.2.0 DEBRIS LOCATED (IMPORTANT CHECKS)
a) Remove the debris and reinstall Valve #65
b) Return to Service Mode.
c) Attempt to set Loading Pressure maximum to between 23 and 25 psi. If maximum pressure will not adjust
below 30 psi, TWO (2) possibilities:
1)
Debris that was not located or reoccurred OR;
2)
Bad Loading
Pressure Valve #65.
