Flushing the Distribution Pipe Network
Before starting the flushing procedure, inspect the complete piping network, and replace any pipe or fit-
tings that have been subjected to direct flame or excessive heating. The following procedure describes
flushing the pipe network with a spare/test cylinder. The pipe network can also be flushed utilizing an
external water supply if available.
Flushing Procedure with Spare/Test Cylinder
• Check the pressure gauge on each cylinder to ensure it has been depressurized.
• Clean the area with warm soapy water, and rinse with water. Dry thoroughly with dry air or nitrogen.
• Disconnect the Primary Actuator Kit (PAK) stainless steel hose from the primary cylinder valve.
• Remove all cylinders from the system. Refer to “Removing a Cylinder Tank (Empty or Storage)” on
page 73.
• Fill test cylinder(s) with water and pressurize.
• Install a test cylinder for each removed cylinder. Refer to “Install New Cylinder Tank(s)” on page 74.
• Attach a suitable container (or hose to a container or other point of disposal) at each pipe outlet where
a nozzle was installed to collect the water discharge.
• Install the PAK and SVAs onto their respective cylinders.
• Re-arm the control panel by placing the package in “Armed” mode.
• Connect the primary actuator hose securely to the Schrader valve on the primary cylinder.
NOTE: PAK hoses with knurled fitting must ONLY be tightened by hand and not with a tool. If the
PAK hose with a hex fitting was loosened for any reason, this fitting must be torqued to 15 in-lbs.
• Activate the system using the manual activation device.
• Once the system is fully discharged of water, reset the system. Refer to “Reset Overview” on
page 50.
• Remove containers or hoses from all nozzle location pipe outlets.
• Remove test cylinders.
• Connect a nitrogen service tank to system piping service port and blow out the discharge piping to
remove all excess water. Disconnect the nitrogen service tank. Refer to “Dry the Lines” on page 72.
• Install new cylinders at each location. Refer to “Install New Cylinder Tank(s)” on page 74.
• Re-install nozzles, ensuring that all nozzles are in the correct location and properly aimed.
• Complete the Start-up/Test Procedure. Refer to “START-UP/INSPECTION TEST PROCEDURE” on
page 59.
NOTE: Tank cylinder(s) should never be filled in the field with agent.
