WESTERN’S ALARM
1. Connect one 24 VAC lead from the alarm to one 24 VAC terminal on the right side of the circuit board in
the power supply box. (Figure 13)
2. Connect the other 24 VAC lead from the alarm to the other 24 VAC terminal.
3. A jumper wire is connected between one 24 VAC terminal and the common (C) terminal.
4. Connect the alarm signal wire to the normally open (N/O) terminal.

INSTALLING PIGTAILS AND ATTACHING CYLINDERS
1. Remove plastic protective covers from all pigtails.
2. Establish flow direction of check valve in pigtails.
3. Connect pigtails to header check valve outlet bushing with
direction of check valve flow from cylinder to manifold end of
pigtail (the check valve end of the pigtail should be connected to the cylinder). (Figure 14)
4. Check master valves to verify that they are open (turn counter-clockwise to open).
5. Remove protective cylinder caps from full replacement cylinders. With the valve outlet pointed away from you or any-
one else, slowly open each cylinder valve slightly to blow out any dirt or contaminants which may have become
lodged into the cylinder valve.
6. Place and secure full cylinders into position using chains, belts, straps, or cylinder stands.
7. Connect pigtails to cylinder valves and tighten securely.
8. S-L-O-W-L-Y turn each cylinder valve until each cylinder is fully open.
CAUTION:
•
Pigtails should never be kinked, twisted, or bent in a radius smaller than 3 inches. Mistreatment may cause
pigtail to burst (refer to attached caution tags on each pigtail).

9. Check all cylinder and pigtail connections for leaks using Western leak detector LT-100 or an oxygen safe equivalent
solution.
10. Observe the following conditions:
•
The line pressure will be indicated on the front of the cabinet.
•
The pressure reading on each bank being pressurized will display cylinder pressure.
•
The green “In Service” and yellow “Ready for Use” lights are illuminated when both banks are full.
