Section 4 Uncrating and Inspection On arrival, do a full inspection by checking all packages and crates in the shipment for damage. If damage is found, sign for the damage or refuse the shipment. Contact the carrier immediately and file a shipping damage claim with the carrier. Check to ensure all components are contained and no visible damage has occurred during shipping. -
Page 13: Section 5 Installation Of Nitrogen Generator
The NGPSA-1700 and NGPSA-2200 air tank and compressor must be mounted separate from the base. • Use the feet on the air tanks to anchor them to a level surface close to the Nitrogen Generator base. Floor mounting the NGPSA-1000 Floor mounting the generator (NGPSA-1700 & NGPSA-2200) Floor mounting the air tank (NGPSA-1700 &... - Page 14 Close the ½” nitrogen outlet shutoff valve on the nitrogen storage tank. See Section 2.2 General • Arrangement Views for reference. Use the supplied 10’ of ¼” OD tube to run the drain line from the base of the generator. See Section 2.2 •...

Page 15: Wiring
Use the supplied wiring cable from the electrical enclosure to connect to the motor. Follow the wiring instruction inside the motor wire cover. Take note of the voltage, the NGPSA-1700 & 2200 are dual voltage motors, ensure that the correct wiring instruction is followed. 5.2 Wiring Diagrams Figure 1. NGPSA-1000 wiring diagram 1-800-345-8207... - Page 16 Figure 2. NGPSA-1700 & 2200 wiring diagram Wiring location is inside the generator electrical enclosure. If you are installing a 3-phase unit, rotation direction will need to be checked for the air compressors. Flywheel rotation is counter-clockwise when looking at the fan end of the compressor as shown below. If rotation is not correct, then switch any two of the 3 wires (L1, L2, or L3) on the terminal blocks inside the electrical enclosure.

Page 17: Initial Air Fill
5.3 Initial Air Fill Before beginning, make sure the water supply to the sprinkler system is turned off and sprinkler piping has • been completely drained. Make sure all piping connections have been made according to installation instructions. • • Close all Air Maintenance Device (AMD) valves. - Page 18 Allow the sprinkler system to reach the required pressure. NOTE: This should finish in 30 minutes per the • required NFPA guidelines. • As soon as the sprinkler system supervisory pressure is reached, put the sprinkler system back into service by placing the AMD in the maintenance position (refer to the AMD manual for proper operation).

Page 20: Section 6 Nitrogen Control Module
Section 6 Nitrogen Control Module The Nitrogen Control Module is an embedded processor with an LCD display used to control the nitrogen generator and provide useful information on alarm, compressor operating hours and cycles, and nitrogen operation. 6.1 Main Display When cycling power to the controller, the initial display will provide the user with the most useful information. - Page 21 When pressing the UP and DOWN ARROW buttons on the controller, the LCD display will scroll through all the information available on the generator. Figure 2 below is an example of what will be shown when scrolling through the display. Figure 4.

Page 22: Section 7 Nitrogen Generator Alarms/Troubleshooting
Section 7 Nitrogen Generator Alarms/Troubleshooting The nitrogen generator has 4 alarms. If an alarm is activated, the bottom row of the LCD display will show the text “ALARM ACTIVE”. The active alarm will remain on the bottom row of the LCD display even when scrolling through the other displays. - Page 23 Alarm 1 – Compressor Overload Issue: The motor overload has tripped due to excessive current. Solution: Turn power OFF to the nitrogen generator. Check overload setting. Reset the thermal overload located at the bottom of the compressor contactor. Measure amperage of motor - check for excessive amp draw.

Page 26: Filter Replacement
Filter Replacement Isolate the nitrogen generator and relieve pressure. Disconnect the power to the nitrogen generator. Unscrew the filter bowl from the filter body. This can be done without disconnecting the drain line. Remove the element by pulling the filter out. Clean the filter body and bowl with a clean rag. -
Page 27: Section 10 Normal Operating Parameters
Section 10 Normal Operating Parameters The NGPSA System uses a two-tank system design to deliver high purity nitrogen. The pressure transducer on the air storage tank controls the air compressor by turning it on and off between 85-105 PSI. Another pressure transducer on the nitrogen tank controls the nitrogen shutoff valve in the N2 PSA generator. -
Page 28: Section 11 Nitrogen Analyzer Instructions
Section 11 Nitrogen Analyzer Instructions Component Description The 3 ½ digit liquid crystal display (LCD) provides direct readout of nitrogen concentrations in the range of 0 - 105.0% (100.1% - 105.0% used for calibration 3 ½ Digit Display determination purposes). The digits also display error codes and calibration codes as necessary. -
