Section 4 Fill Procedure
Attaching the electric valve actuator to the cylinder valve when the actuation pin is not fully locked into the “up”
position may cause the cylinder valve to actuate, resulting in potential injury and/or property damage.
• Reset the electric valve actuator by pushing the pin up until it latches. If the pin is not reset, the valve
core stem could be depressed when the electric valve actuator is threaded onto the valve top causing the
cylinder valve to actuate.
• e electric valve actuator is to be installed hand tight to the valve actuation connection located at the
top of the cylinder valve until contact is made between the actuator and valve top. A small gap will be
present between the bottom of the actuator and the valve body.
Attaching the manual valve actuator to the electric valve actuator when the actuation pin is not fully locked into
the “up” position may cause the cylinder valve to actuate, resulting in potential injury and/or property damage.
• Reset the manual valve actuator by pulling up on the palm button and inserting the ring pin. e
actuation pin should be in the full up position before installing on the electric valve actuator. If the
pin is not reset the valve could open when the manual valve actuator is threaded onto the electric valve
actuator.
• e manual valve actuator is to be installed hand tight to the top of the electric valve actuator until
contact is made between the manual valve actuator and the top of the electric valve actuator. A small
gap may be present between the bottom of the manual valve actuator and the top of the electric valve
actuator.
• Remove the manual valve actuator ring pin and depress the emergency release button. is will open
the cylinder valve.
• Monitor the scale to determine when the cylinder assembly approaches the target fill weight. e target
weight will be approximately the cylinder empty weight plus the intended agent fill weight. Utilize the
pump control knob to increase or decrease the pump speed as necessary.
• Upon reaching the target cylinder weight, close the manual agent fill valve of the cylinder fill assembly
and turn the pump control knob into the off position.
• Remove the electric valve actuator and manual valve actuator. Follows the steps described in Sections
4.2.1 and 4.2.2 to close the cylinder valve and weigh the cylinder assembly.
4.3 Pressurization Procedure
Once the target agent fill weight has been confirmed, the cylinder assembly must be pressurized with
nitrogen to 360 psi at 70°F.
• Replace the anti-recoil safety device with the appropriate Series fill adapter for the cylinder assembly
being filled.
