WARNING - INSTALLATION AND MOUNTING The user of these devices must conform to all

applicable electrical, mechanical, piping and other codes in the installation, operation or repair of these devices. Installation! Do not attempt to install, operate or repair these devices without proper training in the technique of working on pneumatic systems and devices, or under trained supervision. Compressed air systems contain high levels of stored energy. Do not attempt to connect, disconnect or repair these products when a system is under pressure. Always exhaust the pressure from an air system before performing any service work. Failure to do so can result in serious personal injury. Mounting! Devices should be mounted and positioned in such a manner that they cannot be accidentally operated.

REASSEMBLY AND INSTALLATION. After inspection, install replacement parts and reassemble the logic flow control valve as follows: A. Install packing (10. 11), and guide (9). B. Rotate nut (14) counterclockwise until fully out. C. Install packing (8) and cap (7). D. Install filter (6) and packings (3 and 5). E. Install base (4) to flow control valve housing

(16). Secure with lock washers (21) and two screws (1).

F. Install packings (3). G. Install two screws. Secure figure 1-4A in place

on the Logic Panel. TESTING. Attach the Logic Valve to a sub-plate as shown on page 25. Connect supply pressure to port 1 and put a gauge in port 5 and port 3. Turn on the supply pressure to 100 psi. Read the pressure on gauge 5 should read the same as the supply pressure and gauge 3 should read zero. Back the pressure to zero and reverse lines 1 and 3. Increase pressure to 100 psi and gauge 5 should read 100 psi and gauge 1 should read zero. Back the pressure to zero and disconnect the lines.

NOTICE TO PRODUCT USERS

1. WARNING: FLUID MEDIA AVENTICS pneumatic devices are designed and tested for use with filtered, clean, dry, chemical free air at pressures and temperatures within the specified limits of the device. For use with media other than air or for human life support systems, AVENTICS must be consulted. Hydraulic cylinders are de-signed for operation with filtered, clean, petroleum based hy-draulic fluid; operation using fire-resistant or other special types of fluids may require special packing and seals. Consult the factory. 2. WARNING: MATERIAL COMPATIBILITY Damage to product seals or other parts caused by the use of noncompatible lubricants, oil additives or synthetic lubricants in the air system compressor or line lubrication devices voids AVENTICS warranty and can result in product failure or other malfunction. See lubrication recommendations below. AIR LINE LUBRICANTS! In service higher than 18 cycles per minute or with continuous flow of air through the device, an air line lubricator is recommended.* (Do not use line lubrication with vacuum products.) However, the lubricator must be main-tained since the oil will wash out the grease, and lack of lubri-cation will greatly shorten the life expectancy. The oils used in the lubricator must be compatible with the elastomers in the device. The elastomers are normally BUNA-N, NEOPRENE, VITON, SILICONE and HYTREL. AVENTICS recommends the use of only petroleum based oils without synthetic addi-tives, and with an aniline point between 180° F and 210° F. COMPRESSOR LUBRICANTS! All compressors (with the exception of special "oil free" units) pass oil mist or vapor from the internal crankcase lubricating system through to the com-pressed air. Since even small amounts of non-compatible lubri-cants can cause severe seal deterioration (which could result in component and system failure) special care should be taken in selecting compatible compressor lubricants. 3. WARNING: INSTALLATION AND MOUNTING The user of these devices must conform to all applicable elec-trical, mechanical, piping and other codes in the installation, operation or repair of these devices.

INSTALLATION ! Do not attempt to install, operate or repair these devices without proper training in the technique of work-ing on pneumatic or hydraulic systems and devices, unless under trained supervision. Compressed air and hydraulic sys-tems contain high levels of stored energy. Do not attempt to connect, disconnect or repair these products when a system is under pressure. Always exhaust or drain the pressure from a system before performing any service work. Failure to do so can result in serious personal injury. MOUNTING! Devices should be mounted and positioned in such a manner that they cannot be accidentally operated. 4. WARNING: APPLICATION AND USE OF PRODUCTS The possibility does exist for any device or accessory to fail to operate properly through misuse, wear or malfunction. The user must consider these possibilities and should provide ap-propriate safe guards in the application or system design to prevent personal injury or property damage in the event of a malfunction. 5. WARNING: CONVERSION, MAINTENANCE AND REPAIR When a device is disassembled for conversion to a different configuration, maintenance or repair, the device must be tested for leakage and proper operation after being reassembled and prior to installation. MAINTENANCE AND REPAIR! Maintenance periods should be scheduled in accordance with frequency of use and working conditions. All AVENTICS products should provide a minimum of 1,000,000 cycles of maintenance free service when used and lubricated as recommended. However, these products should be visually inspected for defects and given an "in sys-tem" operating performance and leakage test once a year. Where devices require a major repair as a result of the one million cycles, one year, or routine inspection, the device must be disassembled, cleaned, inspected, parts replaced as re-quired, rebuilt and tested for leakage and proper operation prior to installation. See individual catalogs for specific cycle life estimates. 6. PRODUCT CHANGES Product changes including specifications, features, designs and availability are subject to change at any time without no-tice. For critical dimensions or specifications, contact factory. *Many AVENTICS pneumatic valves and cylinders can operate with or without air line lubrication; see individual sales catalogs for details.

LIMITATIONS OF WARRANTIES & REMEDIES AVENTICS warrants its products sold by it to be free from defects in material and workmanship to the following: For twelve months after shipment AVENTICS will repair or replace (F.O.B. our works), at its option, any equipment which under normal conditions of use and service proves to be defective in material or workmanship at no charge to the purchaser. No charge will be made for labor with respect to defects covered by this Warranty, provided that the work is done by AVENTICS or any of its authorized service facilities. However, this Warranty does not cover expenses incurred in the removal and reinstallation of any product, nor any downtime incurred, whether or not proved defective. All repairs and replacement parts provided under this Warranty policy will assume the identity, for warranty purposes, of the part re-placed, and the warranty on such replacement parts will expire when the warranty on the original part would have expired. Claims must be submitted within thirty days of the failure or be subject to rejection. This Warranty is not transferable beyond the first using purchaser. Specifically, excluded from this Warranty are failures caused by mis-use, neglect, abuse, improper operation or filtration, extreme temperatures, or unauthorized service or parts. This Warranty also ex-cludes the use of lubricants, fluids or air line additives that are not compatible with seals or diaphragms used in the products. This War-ranty sets out the purchaser's exclusive remedies with respect to products covered by it, whether for negligence or otherwise. Neither, AVENTICS nor any of its affiliates will be liable for consequential or incidental damages or other losses or expenses incurred by reason of the use or sale of such products. Our liability (except as to title) arising out of the sale, use or operation of any product or parts, wheth-er on warranty, contract or negligence (including claims for consequential or incidental damage) shall not in any event exceed the cost of replacing the defective products and, upon expiration of the warranted period as herein provided, all such liability is terminated. THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, WHETHER FOR MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR OTHERWISE. No attempt to alter, amend or extend this Warranty shall be effective unless author-ized in writing by an officer of AVENTICS Corporation. AVENTICS reserves the right to discontinue manufacture of any product, or change product materials, design or specifications without notice.
