The ECS Protector Nitrogen Generator is designed for
use in maintaining supervisory gas and facilitang the
Dry Pipe Nitrogen Inerng (DPNI) process for
controlling oxygen corrosion in dry and pre-acon re
sprinkler systems. The ECS Protector is an on-site
nitrogen generaon system that is designed to be
installed inline between the compressed air supply
and the sprinkler system riser in dry or preacon pipe
sprinkler systems. The nitrogen generator ulizes
membrane gas separaon technology that exhausts
oxygen as a waste gas to produce 98%+ nitrogen on
demand with no nitrogen storage necessary for dry or
preacon systems.
The ECS Protector Nitrogen Generator cabinet has an
external bypass valve to allow for nitrogen generator
maintenance or “fast ll” needs, and is designed to
meet the NFPA 13 30-minute ll requirement for dry
pipe or preacon re protecon systems.

Installaon Instrucons
Installaon of the ECS Protector Nitrogen Generator requires ve (5) steps:
1. Mount the cabinet in the appropriate installaon locaon
2. Bring the dedicated power supply to the cabinet
3. Plumb the nitrogen/air supply line to the water based re sprinkler risers being served
4. Plumb the condensate drain line to oor drain or building exterior
5. Connect Nitrogen generator output signals to BMS or re alarm system, where applicable
Step 1: Mounng the nitrogen generator cabinet
The ECS Protector Nitrogen Generator is designed to be mounted directly to the oor and/or the wall at
the installaon locaon. Several factors should be considered in choosing the proper mounng locaon
for the nitrogen generator:
• Access to required power supply (dedicated circuit)
• Access to sprinkler risers being supplied from nitrogen generator
• Access to drain for the condensate discharge line
Note: The cabinet includes pre-punched holes in the feet for oor mounng and holes in the back panel
for wall mounng using standard anchors.
STEP 2: Power Supply
The ECS Protector Nitrogen Generator requires a dedicated power supply to prevent interrupon from
other equipment. The incoming power supply line es into the top of the terminal blocks inside the
nitrogen generator cabinet (see diagram). The landing points are labeled L1, N, and G.
Step 3: Plumb the Nitrogen/Air Supply Line
The nitrogen/air discharge plumbing from the ECS Protector Nitrogen Generator is to be connected
directly to the sprinkler system valve trim using ½” to 1” black steel, galvanized steel, or copper lines.
The size of the nitrogen/air supply line shall be based on both the length of pipe between the nitrogen
generator and re sprinkler systems and the total volume of re sprinkler systems being supplied. The
nitrogen generator requires an in-line Air Maintenance Device (AMD) that is equipped with an on board
eld adjustable pressure regulator for each zone being served. The preferred AMD is the Victaulic Series
757.

Note: When both dry pipe and preacon re sprinkler systems are connected to one nitrogen generator,
addional equipment may be required if the re sprinkler systems operate at dierent supervisory gas
pressures.
Step 4: Plumb the Condensate Drain Line
The ECS Protector Nitrogen Generator will occasionally discharge a small amount of condensate water
from the coalescing lters inside the cabinet. It is recommended that the ¼” drain connecon be
plumbed to a oor drain or building exterior. When plumbing to a drain is not feasible an evaporave
collecon chamber can be used.
Step 5: System Signals and Monitoring, where used
The nitrogen generator cabinet has two (2) system signals and ve (5) outputs that can be monitored
by the facility’s BMS or re alarm system.
• The nitrogen generator is operang in the bypass mode which is acvated when the bypass valve is
in the “fast ll” posion to fast ll the re sprinkler system and the air supplied directly from the
air compressor has reached a pressure of 20 psig (1.4 bar). (Flashing amber light)
• The nitrogen generator is equipped with a leak monitor audible signal which is acvated when the
nitrogen generator runs excessively. (Audible signal)
The nitrogen generator cabinet includes system monitoring signals which can be monitored through a
building monitoring system, if desired:
• Nitrogen Generator Loss of Power (Form C contacts)
• Bypass Mode Alarm (Form C contacts)
• Nitrogen Generaon Mode (Form C contacts)
• Nitrogen System Supply Line Pressure (Analog Signal)
• Leak Monitoring (Form C contacts)

Maintenance of the ECS Protector Nitrogen Generator
The nitrogen cabinet contains three (3) separate cartridge lters. It is recommended that each lter be replaced
as part of an annual preventave maintenance program. In some environments it may be necessary to replace
lters more frequently. The lter kit for the PGEN-30 (PGEN-30E) is part number PGEN-FKS. When maintained
properly the nitrogen separaon membrane will provide up to 20 years of service life.
Filter Replacement Procedure
Preliminary Steps (taking the nitrogen generator out of service)
1. Turn the power supply to the unit o
2. Close the inlet and outlet ball valves on the bypass loop
3. Depressurize the nitrogen generator internal inlet piping by slowly unscrewing the petcock valve on the boom
of the lemost lter housing
Coalescing Filter Cartridge Replacement Procedure
The lters with condensate drain tube extending from the boom of the lter housing are coalescing lters. To
replace the lter cartridges follow Steps 1 through 6 on the following page.

Step 1: Grasp the ¼” clear drain tube on the boom of the lter housing with the right hand. With the le hand,
push upward on the grey retaining ring on the lter housing outlet ng. This will allow for the ¼” clear
drain tube to be removed from the ng.
Step 2: Once the ¼” clear drain tube has been disconnected, the lter housing bowl may be unscrewed from the
top poron of the lter housing which is connected to the internal system piping.
Step 3: Once the lter housing bowl has been unscrewed, the lter cartridge inside is removed by rst
unscrewing the black retaining disc at the base of the cartridge and then pulling down on the cartridge.
Discard the old lter cartridge and replace it with the appropriately marked lter cartridge from the
lter replacement kit by pushing up so that it ts snugly onto the receiving cylinder in the upper part of
the lter housing. Screw the black retaining disc back onto the central metal threaded rod.
Important: HAND TIGHTEN ONLY!
Step 4: Replace the lter housing bowl by screwing it onto the lter housing top.
Important: HAND TIGHTEN ONLY!
Step 5: Reconnect the ¼” clear drain tube into the ng on the lter housing bowl. Make sure that it fully seats
in the ng and is retained snugly.
Step 6: Repeat Step 1 through Step 5 for each addional lter.

Acvated Carbon Filter Replacement Procedure
The lter without condensate drain tube extending from the boom of the lter housing is an acvated carbon
lter. To replace the lter cartridge follow the steps below:
Step 7: Remove the lter housing bowl by unscrewing it from the top poron of the lter housing which is
connected to the internal system piping.
Step 8: Once the lter housing bowl has been removed, the lter cartridge inside is removed by rst unscrewing
the black retaining disc at the base of the cartridge and then pulling down on the cartridge. Discard the
old lter cartridge and replace it with the appropriately marked lter cartridge from the maintenance kit
by pushing up so that it ts snugly onto the receiving stepped cylinder in the upper part of the lter
housing. Screw the black retaining disc back onto the central metal threaded rod.
Important: HAND TIGHTEN ONLY!
Step 9: Replace the lter housing bowl by screwing it onto the lter housing top.
Important: HAND TIGHTEN ONLY!
Step 10: Tighten the petcock valve to the closed posion.
Step 11: The ECS Protector Nitrogen Generator can now be placed back into service.
Return the ECS Protector Nitrogen Generator to Service
1. Turn the power supply to the unit on.
2. Open the inlet and outlet ball valves, and close the bypass valve on the bypass loop.
3. Check inside the nitrogen generator cabinet for leaks using a soap water soluon. Tighten ngs where
needed.
