1. MEEN NN ME LOW EMISSION LAMINATORS A WARNING Before using the LEL gun be sure to read and understand all warnings included in this part sheet The Binks LEL Low Emission Laminator gun 207 12200 is a high performance nonatomizing internal mix application device for the application of polyester and other catalyzed resins All Binks branded FRP applicators indicated as LEL or LEL technology utilize impinging fluid streams at low pressure to generate low velocity resin and gel coat fans and are therefore defined by the EPA NESHAP 40 CER part 63 as nonatomizing If the LEL gun is used according to the instructions listed in this part sheet it will provide the user with higher transfer efficiency a cleaner work space and help enable MACT compliance by allowing the use of nonatomized mechanical application UEF factors when calculating plant emissions BINKS LEL GUN ASSEMBLIES Model 207 12200 LEL GUN Model 207 12240 LEL CHOPPER GUN E _ SH 207 12200 LEL GUN ASSEMBLY PACKAGE CONTENTS 207 12217 NIGHT PLUG 207 12230 TOOL 207 12247 207 12377 77 2753 LEL GUN REPAIR KIT EXTRA CLEARANCE PIN PART SHEET 207 12240 LEL CHOPPER GUN ASSEMBLY PACKAGE CONTENTS 207 10501 SQUARE CHUTE 207 10903 CHOPPER SPARE PARTS KIT ANGLED CHUTE NIGHT PLUG 207 12194 207 12217 207 12230 TOOL 207 12247 207 12377 77 2753 LEL GUN REPAIR KIT E2. 9 Keep hands and fingers clear of the pump manifold fluid inlet and the individual inlets The powerful suction can cause serious bodily injury and any breaks in the skin can allow exposure to the chemicals in the formulation being pumped 10 Pressure relief procedure must be followed whenever the pump is shut off for cleaning servicing or repairing any part of the air or fluid system This includes removing or installing or cleaning spray gun tips or nozzles See the pressure relief procedure in the pumping equipment part sheet REPLACEMENT PARTS The spray gun is designed to use authorized parts only When using this LEL gun with parts that do not comply with the minimum specifications and safety devices of Binks the user assumes all risks and liabilities Do not handle or use until safety precautions concerning Methyl Ethyl Ketone Peroxides in the Manufacturer s literature have been read and understood Contact with foreign materials especially strong mineral acids metals including certain equipment and containers or metal salts or exposure to heat above 135 F 57 C may lead to violent decomposition releasing flammable vapors which may self ignite Do not get into eyes or on skin or clothing Wear eye and skin protection when handling Avoid breathing mist Use with adequate ventilation Store only it in the original closed container Wash hands thoroughly after handling Protect from direct sunligh

HEATERS FILTERS etc The same possibility of an explosion is possible with the galvanized coatings in pressure tanks The possibility of a non flammable explosion increases greatly at high operating temperatures The explosion could be of sufficient strength to cause bodily injury death and substantial property damage Cleaning agents coatings or adhesives may contain HALOGENATED HYDROCARBON SOLVENTS CHECK WITH YOUR SOL VENT AND PAINT SUPPLIER Models 207 12220 amp 207 12240 LEL GUNS are constructed with components of aluminum alloy and SHOULD NOT be used with any Halogenated Hydrocarbon solvents If you are now using a Halogenated Hydrocarbon Solvent in a pressurized fluid system with aluminum components or galvanized wetted parts the following steps should be taken immediately 1 Remove all pressure drain and disconnect the entire system 2 Inspect and replace all corroded parts 3 Contact your solvent supplier for a NON HALOGENATED SOLVENT to flush and clean the system of all residues HALOGENATED Solvents are defined as any hydrocarbon solvent containing any of the following elements CHLORINE CHLORO CI BROMINE BROMO Br FLUORINE FLUORO F IODINE IODO 1 Of those listed the Chlorinated Solvents will most likely be the type used as a cleaning agent or solvent in an adhesive or coating The most common are METHYLENE CHLORIDE 1 1 1 TRICHLORETHANE PERCHLORE
4. Inform your doctor specifically of what fluid was injected AVOID STATIC SPARKING Static electricity charge builds up by high velocity liquid flowing through a hose during flushing cleaning or spraying operations Proper grounding of the airless system safely dissipates this charge GROUNDING THE PUMP Installation of the ground wire attachment to a metallic portion of the pump must insure a secure metal to metal contact The ground wire must be 12 gauge minimum A clamp must be attached to a true earth ground and an instrument test must be done to verify a ground Mounting is the user s responsibility All high pressure airless systems must be grounded to avoid dangerous static sparking explosion or fire when spraying or flushing with flammable liquids Use Binks NO WIRE conductive hose in all airless spraying operations Be sure the gun and hose have continuity Check continuity weekly with ohmmeter Overall end to end resistance of un pressurized hose must not exceed 29 mega ohms max for any coupled length or combination of hose lengths 2 Make sure the pump is grounded NEVER operate the unit when it is on a non grounded platform LA When flushing or cleaning with a combustible solvent always use an open metallic container for receiving the waste solvent Ground the solvent receptacle 4 Bond the spray gun to the waste container with a grounding wire Be sure there is good metal to meta
