the scheduled maintenance specified in this manual warnings in this manual cover the most known potential hazards but by definition cannot be all inclusive If the user employs operating procedure item of equipment or a method of working that is not specifically recommended by Potter Electric Signal the user must ensure that the equipment will not be damaged or become hazardous to persons or property INS PVfirealarmresources com System Overview Potter IntelliPurge Nitrogen Purge Valve INS PV is designed to work with Potter IntelliGen Series Nitrogen Generators to effectively corrosive oxygen from a fire sprinkler system while maintaining adequate system pressure Potter IntelliPurge Nitrogen Purge Valve is easiest way to ensure high purity nitrogen is equally distributed throughout the fire sprinkler system Simply install the INS PV at the end of sprinkler system near a 24 Volt AC DC electrical connection When the nitrogen generator is in operation the INS PV bleeds out the oxygen one of three modes that are selectable using DIP switch configuration or by selecting the mode on the IntelliGen Nitrogen Generator The Purge Modes for the INS PV include Purge When the INS PV is in Perfect Purge Mode the unit purges the air out of the system until 98 N2 purity is reached This is the unit default setting Shot In this mode a Purge Time is selected and the valve automatically shuts off after that time expires This mode is designed for freezers or ice plug applications After the system reaches 98 purity it will cyclically open and This allows any excess trapped moisture to be periodically purged while still lowering the duty cycle at the compressor additional information on Purge Modes see page 29 the event of a system activation the INS PV has a built in high pressure water shut off valve that automatically closes when the water reaches vent A ball valve allows for isolation of the assembly maintenance of strainer screen replacement of air vent or maintenance of the purge See Figure 1 for INS PV System Diagram 1 INS PV System Diagram FROM SPRINKLER SYSTEM 20 1 4 7 1 8 7 3 8 NPT TEE CONNECTION AND CLOSE NIPPLE BY SPRINKLER CONTRACTOR TEST VALVE POSITION VENT

damage If damage is found sign for 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 List Transformer PV 5270462 1119478 1119478 Read all of the safety information in this manual before installing or operating this equipment Find a location to install the INS PV that meets these requirements to front and top for maintenance located near power requirements 24 Volt AC DC for INS PV 7.3 x 6.8 x 7.9 H x W x D clean well ventilated covered and away from high voltage power temperatures between 4 20 and 122 50 INS PV should always be installed in an adequately ventilated room Nitrogen is nontoxic and largely inert release of nitrogen gas into an enclosed space displaces the oxygen and can cause an asphyxiation hazard of nitrogen in excessive concentrations can result in unconsciousness without any warning symptoms Run a 24 Volt AC DC wire to installation location for INS PV Class 2 Transformers available for 120 V application gage must be considered when running power for long to the INS PV Refer to Figure 3 3 For PLINK networking the INS PV requires 3 signal lines to allow communication PL A PL B and PL G The PLINK network requires 3 wire twisted stranded cable CAT5 cable with the unused wires trimmed is recommended
