7.3 CHECKING FOR LEAKS
To prevent leakage, all threaded connections should have Teflon tape (or suitable alternative) and all
compression fittings should be installed per manufacturer’s recommendations.
1. Locate the BLOCK SOLENOID. Turn the override screw on the BLOCK SOLENOID and SPAN SOLENOID to the
manual position.
2. Use leak detection spray on all compression fittings and bends of the cal and reference line tubing.
3. Inspect the full length of the tubing to determine if there is a leak.
4. Repair leaks as necessary, and within applicable guidelines.
5. After repairing the leaking areas, repeat the inspection instructions above for the affected areas.
6. Upon completion of repairing the leaks, return all solenoids to the AUTO position.
