for the safety installers operators and users of the Potter Nitrogen Generator To help recognize this information observe the following indicates an imminently hazardous situation which if not avoided WILL result in death or serious injury indicates a potentially hazardous situation which if not avoided COULD result in death or serious injury indicates a potentially hazardous situation which if not avoided MAY result in minor or moderate injury indicates important information that if not followed may cause damage to equipment or property Notice to Users Installation and Owner Manual supplied with each unit must be read thoroughly and completely understood before and operation of the Potter Nitrogen Generator All appropriate safety standards for handling of gases as determined local or national laws and regulations should be followed at all times unpacking unit carefully inspect all parts and equipment for any damage that may have occurred during transit Make sure tighten fittings bolts etc before putting unit into service not operate if damage occurred during shipping handling or Contact Potter immediately Safety Information Read all of the safety information in this manual before operating this equipment Use of the equipment in a manner specified within this manual may impair the protection provided by the generator and could result in an unplanned release of which may cause serious injury or damage Only competent personnel who have been trained qualified and approved Potter Electric Signal Company should perform commissioning servicing and repair procedures handling installing or operating this equipment personnel must employ safe engineering practices and observe all related regulations health and safety procedures and legal requirements for safety that the equipment is depressurized and electrically isolated before carrying out any of the scheduled maintenance specified in this manual NGP 300Dfirealarmresources com 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 is not a poisonous gas However in a concentrated form there is a risk of asphyxiation The generator produces a flow nitrogen and oxygen enriched air which quickly disperses in the atmosphere However do not directly inhale the output gas the outlet pipe generator is classified as non hazardous for transportation purposes and as non flammable for fire regulations This equipment for indoor use only Do not operate outdoors of the nitrogen membrane separator above the design pressure may be hazardous Do not connect it compressed air sources that can exceed its maximum pressure without installing appropriate pressure and safety relief devices in the compressed air line procedures must be developed for maintenance of the equipment on which the membrane separator is located labels must be continuously displayed in all areas where personnel might be exposed to a nitrogen atmosphere normal or upset condition not attempt to disassemble the nitrogen membrane Equipment damage may occur and cause the to function incorrectly NGP 300Dfirealarmresources com System Overview Potter Nitrogen Generator operates using membrane technology The smaller oxygen and water vapor molecules can pass permeate the membrane quickly The larger nitrogen molecules are less likely to diffuse through the separator tubes they continue downstream to the separator outlet The permeated molecules are discharged to the atmosphere through a in the separator casing Potter Nitrogen Generator is specifically designed to provide clean dry high purity nitrogen for use in fire protection systems The generator is a fully assembled package ready to be connected to a new or existing fire sprinkler system a factory pre engineered air compressor These turn key systems include all air filtration equipment required to keep the operating at peak efficiency 1 NGP 300D System Diagram
