[. . . ] Operator's Manual High Pressure Breathing Air Compressors Operator's Manual INTRODUCTION This manual contains general information and instructions to operate and maintain high pressure breathing air compressor units. Before taking the compressor into operation it is essential to study the instruction manual of that compressor. All instructions should be observed and carried out in the order laid down to prevent damage and premature wear to the equipment and the units served by it. While every effort is made to ensure the accuracy of the particulars contained in this manual, the manufacturing company will not, under any circumstances, be held liable for any inaccuracies or the consequences thereof. WARNING The breathing air produced with this high pressure compressor is subject to strict quality standards. [. . . ] The technically caused excessive increase of CO2 during the filling process and the CO2 peak at taking the unit into operation. Because of the reasons stated above and for your own security, the filling of breathing air bottles is not allowed in rooms used as workrooms. Scavenging the compressor unit CO2 is present in the atmosphere with a natural amount of 250 -- 800 ppmV. The molecular sieve used in the purifiers for drying the breathing air is, as well as other capabilities, able to adsorb CO2 which is accumulated in the cartridge. After shut--down of the compressor, adsorbed CO2 may be desorbed again due to the partial pressure decrease. The now free CO2 then gets washed out of the cartridge when the compressor is started again. To avoid increased CO2 contents in the compressed breathing air, we recommend scavenging the compressor unit before connecting and filling the air bottles, i. e. let the compressed air escape into the open air by opening the filling valves for about 1 to 2 minutes. Remove filling hose for this action, or hold the respective filling hose tightly when opening the filling valve, to avoid any uncontrolled whipping of the filling hose. Switch-over valve Filling panels for 2 pressure ranges (PN 200 / PN 300) and with a switch--over valve, with which it is possible to switch between two pressure ranges, can only be used for one pressure range at a time. The 200 bar side is opened by means of the shut--off valve. The 300 bar filling valves remain pressurized but can only be used up to a pressure of 200 bar. It is impossible to connect 200 bar bottles to the 300 bar filling connections (right hand side). CAUTION Before switching from 300 bar to 200 bar, i. e. to the lower pressure range, it is essential to open the venting valve and to reduce the 300 bar line to at least 200 bar. Otherwise, the pressure gauge could be damaged or destroyed. Pressure reducer WARNING Open the switch-over valve slowly in order to avoid a pressure surge!Filling hoses which are not in use must be hung in the holders on the bottom of the filling panel, so that should a filling valve be inadvertently opened, the pressurized air outstream cannot cause the hose to whip and cause serious injury. Filling panels for 2 pressure ranges (PN 200 / PN 300) and with a pressure reducer, can be used for filling bottles simultaneously at two pressures, i. e. simultaneous filling of 200 bar and 300 bar bottles is possible!The pressure reducer used in the filling panel is adjustable to a high precision. inlet pressure 420 bar Secondary pressure 0. 1 to 280 bar (range of adjustment) Temperature range --10 °C to +100 °C Normal delivery 32 m3.
