6-9 INSTALLATION OF CYLINDERS
6-9.1 CO
2
Cylinders
These instructions must be carefully followed in the exact sequence given below when any
cylinder or group of cylinders are to be installed at any time.
1. Place fully charged cylinder in cylinder rack before removing the cylinder protection cap.
2. Install the cylinder rack and tighten bolts only enough to allow for turning of cylinder as
may be required later.
3. Remove the cylinder protection cap and top protection cap from the cylinder valve. Remove
the side protection cap only from the cylinder valve(s) to be equipped with control head(s).
Return all caps to the storeroom.
4. Turn cylinder so that the cylinder valve control head port points in the proper direction;
tighten bolts of the cylinder rack securely.
5. Make certain that all control head(s) are in the “set” or “closed” position, (actuator plunger
should fully recede into the control head body). Ensure that the locking pin and seal wire
are intact.
6. Install control head(s) onto cylinder valve(s). Tighten securely.
7. Assemble discharge head(s) to cylinder valve(s) and tighten mounting nut.
6-9.2 Nitrogen Pilot Cylinders
1. Install nitrogen cylinder in mounting bracket. Rotate cylinder until valve outlet is in desired
position.
2. Tighten mounting bracket strap.
3. Remove pipe plug and connect adapter (Part No. WK-699205-010) to cylinder valve outlet
port. Attach flexible actuation hose to outlet port adapter.
4. Remove protection cap from cylinder valve control head port.
5. Install control head to cylinder valve.
6. Tighten the control head to the valve. Tightening the control head to the valve requires
that a wrench be used to hold the valve while the control head hex nut is tightened. The
WARNING
When installing charged cylinders, always install the discharge heads last. This
will minimize the possibility of accidentally discharging the CO
2
system, which
could result in possible injury to personnel, or damage to equipment or
property.
WARNING
Control heads must be in the “set” or “closed” position before attaching to the
cylinder valves to prevent accidental carbon dioxide discharge.
WARNING
Control head must be in the “set” or “closed” position before attaching to the
cylinder valve, which will prevent:
• an accidental discharge of the nitrogen cylinder and any corresponding
suppression agent
• a nitrogen leake during actuation
Failure to properly set the control head may cause damage to the unit and could
result in one of the aforementioned concerns.
