Step 8
Secure the detection tubing to the bulkhead by using the clips and screws supplied.
Nylon wire ties may be used in lieu of the clips and screws. Note: Do not exceed a
bend radius of 6 inches during the routing of the tube.
WARNING
WHEN INSTALLING THE DETECTION TUBING, DO NOT KINK THE TUBING AND DO
NOT EXCEED THE MINIMUM BEND RADIUS. FAILURE TO FOLLOW THESE DIRECTIONS
CAN RESULT IN A SYSTEM FAILURE. (See Figure 6)
Step 9
Ensure the spring nut fitting is on tube, and attach by carefully working the tube
completely down on the nipple fitting on cylinder assembly/ (Note: Do not kink tub-
ing, if kink occurs, remove effected area with razor.
Step 10 Tighten fitting and tube to cylinder using 1/2" (12mm) wrench. Preferred torque
value is 3 - 4-1/2 inch pounds of force. Overtightening may cause tube to rupture.
Step 11 Activate system - Using a straight screwdriver, “open valve VERY SLOWLY” counter
clockwise, 1/4 of a turn, to allow detection tube to fill with nitrogen.
Note: Label on valve indicates valve and system status. (ACTIVATE)
Step 12 After tubing is routed, and charged, verify there are no apparent damage, and that
the fitting ends of tubing are leak free.
Note: If a leak is detected, close valve, and re-tighten fittings. If leak persists, remove affected
zone and re-install. Ensure valve is open (Activate) at completion of installation.
