INSTRUCTIONS FOR REINSTALLATION OF CYLINDERS
These instructions are to be carefully observed in the order given below when any cylinder or group of cylinders is to be
reinstalled at any time.
CAUTION:
When reinstalling charged cylinders, always replace the discharge heads last.
This will eliminate the possibility of discharging the carbon dioxide, with possible
injury to personnel.
1.
Place fully recharged cylinder in cylinder rack before removing the cylinder cap. (See sketch on previous page for
identification of parts.)
2.
Install the cylinder strap, and tighten bolts only enough to allow for turning of cylinder as may be required later.
3.
Remove the cylinder cap and the top protection cap from the cylinder valve. Remove the side protection caps from
the cylinder valves to be equipped with control heads.
4.
Turn cylinder so that the control head outlet points in the proper direction; then tighten the bolts of the cylinder racks
securely.
5.
Make certain all control heads have been reset as follows:
A.
Cable-operated Control Head.
(1)
Remove cover from control head.
(2)
Make sure plunger is retracted below surface of control head body, then engage a few threads of the
mounting nut to the cylinder valve.
(3)
Retract actuating roller as far as possible from direction of pull. (Roller should be at start of stroke)
(4)
Replace cover, locking pin, and new seal wire.
NOTE:
When two control heads are connected in tandem, make certain both are
completely reset before assembling to cylinder valves.
B.
Leave-operated Control Head.
(1)
Move lever back to its "closed" position. The plunger should fully recede into control head body.
(2)
Replace locking pin and new seal wire.
6.
Reinstall control head to cylinder valve. Tighten mounting nut.
7.
Connect discharge head to cylinder valve following directions stamped on swivel nut of discharge head. (Older type
discharge heads containing multi-hole corprene gasket must be tightened securely using at least an 18” wrench.
New type discharge heads containing two greased rubber rings should be brought up only snug tight.
8.
Connect hose, flexible loops or piping to discharge head outlet.
