Secure cylinders by tightening the straps at the buckle and mate the velcro sections to prevent slipping. 2216psi (153 bar) or 4500psi (310 bar) cylinders can be used. STEP 2) Install universal CGA-347 hand tight nuts to the cylinder valves and tighten. Insure both bleeder valves are closed by turning fully clockwise. STEP 3) Open one cylinder. STEP 4) Index the selector valve so that it points to the open cylinder. At this time, the low pressure warning alarm will sound until it sets itself at approximately 1000psi (69 bar). Check reading on gauge to verify that it is full. Close the cylinder Setup/Operation STRAP BLEEDER VALVES HAND TIGHT SELECTOR VALVE 5 RELIEF VALVE STEP 5) LOW PRESSURE ALARM TEST Set the required respirator pressure with the regulator control knob and bleed the pressure at either the relief valve or by partially engaging a male plug into one of the respirator couplings. This depressurizes the manifold and simulates low cylinder pressure. The low pressure warning alarm will sound at approximately 500psi (35bar). STEP 6) Index the selector valve toward the other cylinder and open the cylinder valve. At this time the low pressure warning alarm will resound until it sets itself at approximately 1000psi (69 bar). Check reading on gauge to verify cylinder is full. Either cylinder can now be selected for operation. Optional Install high pressure connect whip to auxiliary inlet port (CGA- 347). This step can be done after Step 6 or anytime during the operation of the system. This auxiliary inlet port is not controlled by the selector valve. Auxiliary inlet air directly feeds the regula- tor system. STEP 7) Couple respirators and lengths of hoses to the manifold and read- just pressure regulator if necessary. The system is now opera- tional. Optional If pneumatic equipment is to be used which requires a different pressure than the respirators, set the secondary low pressure regu- lator accordingly. This is a locking regulator; push to lock, pull to unlock. RESPIRATOR COUPLING AUXILIARY INLET PORT REGULATOR CONTROL KNOB 6 Shutdown Make sure all personnel have egressed the hazardous area and have disconnected from the breathing air system. 1)Close cylinder valves. 2)Depressurize manifold by pulling the relief valve ring. 3)Close the regulator by turning the control knob counterclockwise. 4) Disconnect airline hoses and reinstall dust caps. 5) Remove connections from cylinders and reinstall cylinder valve covers (if applicable). High Pressure Airline General Maintenance & Inspection Monthly 1. Check regulators, gauges, and valves for external leakage. 2. Inspect cylinder valves for proper closure. 3. Check cylinder pigtails for cleanliness, flexibility, wear, leakage, blisters on hose, thread damage, and O-rings on CGA fittings. Replace damaged items immediately. Annually 1. Check relief valve's pressure setting. 2. Check regulator function by opening and closing regulator valve knob fully. Every 4 years 1. Replace all flexible pigtails - consult factory. Cylinder Change When the cylinder in use has been depleted to approximately 500psi (35bar), the low pressure warning alarm will sound indicating that the cylinder needs to be replaced. To change a cylinder while the cart is still in use: 1) Open the second cylinder and note the gauge pressure to assure that it is full. 2) Index the selector valve towards the full cylinder. 3) Close the drained cylinder valve and open the corresponding bleeder valve to relieve pressure on the hand tight nut. 4) Remove the drained cylinder and install a full cylinder in its place. Connect the CGA-347 hand tight nut to the cylinder valve, close the bleeder valve on the connect whip. It is now ready for use when the other cylinder pressure descends to 500psi or lower. Note: The system is equipped with check valves that will prevent back flow from the other cylin der in use. 7 ITEM # DESCRIPTION PART # 1 LOW PRESSURE WHISTLE AC-PA25 2 CGA-347 HAND-TIGHT NUT/NIPPLE SS347HT 3 BLEED VALVE VAL030 4 CYLINDER STRAP HDWR113A 5 QUICK DISCONNECT, HANSEN SERIES QDH3SL4M 5A QUICK DISCONNECT, SCHRADER SERIES QDSSL4M 6 DUST CAP, HANSEN SERIES QDH3DCAP 6A DUST CAP, SCHRADER SERIES QDSDCAP 7 SECONDARY OUTLET PRESSURE GAUGE GA15160B 8 SECONDARY PRESSURE REGULATOR WL013 9 OUTLET PRESSURE GAUGE GA20160B 10 PRESSURE REGULATOR REG-5000NG 11 INLET PRESSURE GAUGE GA206KB 12 3-WAY BALL VALVE VAL153 13 CGA-347 PRESSURE CAP SS347CAP 14 CGA-347 MALE ADAPTER SS4F347AM Parts Identification 8 Warranty Disclaimer Air Systems? manufactured equipment is warranted to the original user against defects in workman- ship or materials under normal use for one year after date of purchase.

Rev 2 12/98 Air leaks are not covered under warranty except when they result from a defective system component, i.e. an on/off valve or regulator or upon initial delivery due to poor workman- ship. Air leaks due to poor delivery or damage will be covered under delivery claims. Minor air leaks are part of routine service and maintenance and are the responsibility of the cus- tomer just as are filters and oil changes.
