Purging with IntelliPurge
®
Nitrogen Purge Valve (INS-PV):
1. See Manual #5401532 for full details on installing, programming, purging and wiring of the INS-PV.
2. Go to the end of the sprinkler system(s) where the INS-PV(s) is installed. Each riser should have one INS-PV.
3. Check to ensure power is connected to the INS-PV. The green Power LED will be ON.
4. Open the ball valve on the INS-PV.
5. Ensure the INS-PV is installed properly. Installing the valve upside down will cause the unit to not purge. Any trapped water
in the piping will also cause the unit to not purge.
6.
To check that the INS-PV is allowing air/nitrogen flow, toggle the “MANUAL PURGE” switch ON. This will open the
solenoid valves inside the unit.
7.
If the sprinkler system is pressurized, listen for flow out of the Purge Exhaust Port on the bottom of the unit. You may also
use your fingers to feel for flow. If no flow is present, there is a blockage such as a shut ball valve, water in the pipe, or a
clogged orifice upstream.
8. If the INS-PV unit is not connected to a nitrogen generator or an INS-RA, toggle the “START PURGE” switch to start the
Purge Process.
9. Once the Purge Process has started, the yellow Purge LED indicator will begin blinking.
10. The Purge Time Display will display the max number of purge days, which is the maximum amount of time the unit is
allowed to purge before indicating a trouble.
11.
The N2 Level display will blink indicating that it is taking an initial nitrogen level reading. After five minutes the N2 Level
display should read ambient nitrogen levels, between 78-81%.
12. The INS-PV is now purging. The oxygenated air is escaping out of the Purge Exhaust Port.
13. If an IntelliPurge
®
Nitrogen Purge Valve (INS-PV) is connected to a nitrogen generator or an INS-PV, the S1 toggle switch
will be DISABLED.
14. Return to the nitrogen generator.
15. If an INS-PV is connect to the nitrogen generator, press the “PURGE” button on the IntelliGen
™
Display keypad.
16. Follow all prompts.
17. Once the system reaches 98% the INS-PV automatically closes and your system is purged.
