ii.
If leak is suspected from Solenoid (Nitrogen Line), apply Soap Water Solution to the Solenoid in locations
circled in
Figure 49.
Open both regulators fully and inspect for bubble formation to detect leak. If leak is
coming from push to fit locations, first attempt to push the tubes further into the joint; if pushing the
tubing in further is unsuccessful in stopping the leak, replace the Solenoid. Refer to
Appendix H: Nitrogen
Line Solenoid Replacement
for procedure. Wipe all connections checked with Soap Water once test is
complete.
iii.
Check all push to connect fittings with soap solution. If leak is found, try pushing the tube connected to the
push to connect fitting further in. If the tubing is pushed in all the way and there is still a leak, replace the
push to connect fitting. Wipe all connections checked with Soap Water once test is complete.
iv.
Check the Pressure Transducer itself for leak. Cut the cable tie holding the Pressure Transducer against the
foam so soap water can be applied around the barb connection on the Pressure Transducer Board. Check
one pressure transducer at a time and immediately wipe all the Soap Water once test is complete.
See
Figure 50.
If leak is found on the Pressure Transducer, replace the entire Pressure Transducer Assembly.
v.
Check the Pressure Regulator itself for leaks by applying soap solution to the body of the Pressure
Regulator. If the leak is coming from the Pressure Regulator itself, replace the Pressure Regulator and all
fittings. Apply 3-layers of Teflon tape in clockwise direction and tighten the fitting to proper torque setting.
Refer to
Appendix B: John Guest Torque Settings
for proper Torque Setting.
See Figure 51a and 51b.
