2 USER RESPONSIBILITY This equipment will perfm in confmity with the description thereof contained in this manual and accompanying labels and/ inserts when installed, operated maintained in accdance with the instructions provided. This equipment must be checked periodically. Defective equipment should not be used. Parts that are broken, missing, plainly wn, distted contaminated, should be replaced immediately. Should such replacement become necessary, Controls Cpation of America (CONCOA) recommends that a telephonic written request f service advice be made to the CONCOA Warranty Administrat in Virginia Beach, Virginia. This equipment any of its parts should not be altered without the pri written approval of CONCOA. The user of this equipment shall have the sole responsibility f any malfunction which results from improper use, faulty maintenance, damage, improper alteration anyone other than CONCOA a service facility designated CONCOA. SAFETY a. The Regulat relief valve protects only the regulat and is not intended to protect any other equipment. Be sure the equipment with which it is used is also protected relief device(s) is such equipment cannot fully withstand cylinder pressure. b. Never use the Regulat f gases other than labeled. Regulats with Compressed Gas Association (CGA) number 320, 326, and 580 are designed to withstand 3000 PSIG maximum inlet pressure. Regulats with CGA 680 inlet are designed to withstand 5500 PSIG. Do not interchange inlet fittings parts between 3000 PSIG max regulats and 5500 PSIG max regulats. Use of fittings parts other than intended could result in a hazardous condition. c. All connections to the Regulat must be clean. Remove dirt other feign matter from the Regulat and metal connecting parts with a clean lint free cloth. Clean all metal parts that come in contact with the gas stream to remove all traces of grease oil. CAUTION d. Never pressurize a Regulat that has loose damaged parts is in questionable condition. Never loosen a connection attempt to remove a part until gas pressure has been relieved. Under pressure, gas can dangerously propel a loose part. e. Befe transpting a cylinder that is not secured on a cart suitable f such transpt, remove the Regulat and recap the cylinder. f. Stand to one side of the cylinder valve Regulat when opening valve. 2

3 I. INTRODUCTION This manual provides installation, operation, and service infmation f the CON- COA style 8000 Heated Single-stage Regulat. The 8005 and 8008 regulats are flowgauge regulats. Their operating pressure gauge is read in cubic feet per hour (cfh). F all other regulats in the 8000 series, the gauge is read in PSIG. The 8000 series regulats are f use with nonsiphon-type cylinders. The 115-volt Regulat has a 1.3 amp heating system. The 230-volt has a.65 amp heating system. Both regulats heating system s consist of three 50-watt heating cartridges, a thermostat to provide automatic temperature control, and a safety thermostat cutout. The heating system prevents flow reduction and eliminates the problem of regulat freeze up which causes reduction stoppage of gas flow malfunction of the Regulat. II. INSTALLATION a. Observe the precautions listed in the SAFETY Section. b. Befe attaching the regulat, open the cylinder valve to blow out any feign matter from the outlet and close it. c. Connect the Regulat to the cylinder valve outlet, checking that the washer is in place on 320 CGA only. Tighten the connection nut with a proper size wrench. d. The 115-volt models are supplied with a sht 3-wire cd and a molded grounded plug. No plug is provided on the 230-volt models, due to the diversity of 230v. plugs. CAUTION To guard against potential shock and fire hazard: use a three-wire, grounded, extension cd (available from your distribut local supplier); and protect the circuit with a suitable fuse circuit breaker (heaters draw total 1.3 amp f the 115-volt models and.65 amp f the 230-volt models). Never remove ground prong from line cd plug. e. Plug the Regulat line ( extension) cd into a grounded receptacle. The heaters draw a total load of 150 watts. f. Connect downstream equipment hose to the adapt. Slightly open equipment gas valve. Slowly open cylinder valve and purge line to discharge contaminants. Close equipment valve several seconds after pure gas starts to flow from equipment. Open cylinder valve fully and the required gas flow is ready f use. g. Close the cylinder valve and remove line cd from the supply receptacle whenever the regulat is not in use. h. Test all connections f leaks applying a leak detection solution. 3

4 III. OPERATION 3.1 TO ADJUST FLOW RATE OR PRESSURE a. With gas flowing at down stream end, slowly turn Regulat adjusting screw clockwise until desired flow pressure is shown on operating gauge b. To reduce flow rate pressure, turn adjusting screw counterclockwise while allowing gas to flow from downstream valve. 3.2 TO SHUT DOWN a. Close cylinder valve. b. Open downstream valve to drain lines. c. Close downstream valve and remove line cd. 4.1 GENERAL IV. SERVICE SERVICE PROCEDURE A unit which is not functioning properly should not be used until all required s have been completed and the unit has been tested to ascertain that it is in proper operating condition. Gas equipment improperly operated maintained can be hazardours. Service of CONCOA Gas Equipment should NOT be attempted anyone other than a qualified CAUTION No such maintenance should ever be undertaken attempted anyone not having such qualifications. It is recommended that defective parts be replaced with a replacement part manufactured sold CONCOA. Repairs with non-concoa parts may pose a potential shock hazard. Except f inspection and troubleshooting as indicated in this manual, it is recommended that all other servicing be done a service facility authized CON- COA. Contact the CONCOA Authized Distribut from who you purchased the regulat the nearest CONCOA Regional Sales Office f assistance.

Return trip transptation charges are to be paid Buyer. In all cases other than where warranty is applicable, s will be made at current list price f the replacement part(s) plus a reasonable lab charge. 4

5 IMPORTANT Checking of this equipment limited to replacement of nonpressurized external parts such as electrical components, may dinarily be undertaken a competent individual having experience in the maintenance and of equipment of this nature. No such checking should ever be undertaken attempted anyone not having such qualifications. 4.2 TROUBLE INDICATIONS Typical symptoms in the accompanying table indicate Regulat malfunctions requiring. Replace immediately with a clean, ed and tested, new Regulat.
