Charging A Spare/Test Cylinder; Installing A Cylinder; Rechecking The System - CaptiveAire EWC Installation, Operation And Maintenance Manual

Charging a Spare/Test Cylinder

1. Secure the cylinder in a chain vice, strap vice, or similar.
2. Ensure the cylinder has been hydrostatically tested, if applicable, and has been cleaned and
inspected.
3. Fill the cylinder with approximately 4 gallons of clean water.
4. Re-install the valve/siphon tube assembly onto the cylinder and torque to 25 ft/lb.
5. Connect the external nitrogen supply to the cylinder valve outlet with a discharge adapter. Refer to
Figure 53.
6. Pressure the cylinder with nitrogen to approximately 200psig at 70°F. Refer to Table 23 for pressure
variation with temperature.
7. Turn off nitrogen supply and disconnect cylinder.
8. Remove the discharge adapter kit.
9. Immediately install the Anti-Recoil and Valve Protection Plates. Refer to Figure 50.

Installing a Cylinder

All removed cylinders must be replaced with new (fully charged) or properly re-charged cylinders. Follow
these steps to install a cylinder:
1. Lubricate a new O-ring with Parker Super O-Lube and install on the discharge adapter.
2. Remove the anti-recoil cap and place the cylinder into position, ensuring a tight seal with the discharge
adapter.
3. Strap the cylinder onto the cylinder bracket.
4. Bolt the cylinder valve to the discharge adapter and cylinder bracket. Refer to page 13 and page 14 for
details on installing the PAK and SVA.

Rechecking the System

After the inspections and procedures described previously in this section, the fire-suppression system is
ready to be fully checked out before installation of the replacement wet chemical cylinders.
1. Follow the system commissioning and test procedures outlined in "Start-up/Test Procedure" on
page 60.
2. Be sure to check the system for all modes of operation.
