Resetting Maintenance Alert and Checking for Leaks:
20.
Remove old O-rings and replace with the O-rings in the filter element kit.
21.
Clear filter bowls of debris.
22.
Screw the filter bowl back into the filter body. Use a 13/16” wrench to tighten the correct wrenching flats. Be careful to not
over tighten or you may crack the filter body. Repeat for all filters.
23. Close the black handled ball valve on the Activated Carbon Filter (F04) and the blue N
2
Bleed Valve (V04).
24. Turn power on to the unit using the electrical disconnect.

™
Display keypad.

™
Display will turn off and the maintenance timer has been reset.
32. Turn power back on to the air compressor using the Air Compressor Switch located on the right of the cabinet. The amber
"BYPASS" LED will be ON since there is no pressure in the tanks.
33. If the nitrogen generator is isolated from the sprinkler system:
a. The air compressor of the INS-500 should take no longer than 8 minutes to pressurize the two tanks and turn off.
b. The air compressor of the INS-1000 should take no longer than 6 minutes to pressurize the two tanks and turn off.
34. The amber "BYPASS" LED should turn off.
35. If the air compressor is not turning off or it is taking longer than expected, it could indicate a leak.
36. Allow the system to hold pressure for several minutes. Check all piping connections for leaks. Any drop in pressure on the
nitrogen tank or air tank during this time could indicate a leak.
37.
If there is a drop in pressure, soap all filters and blow-down strainer.
