3. Warnings and cautions Be careful when using with small chamber or low pressure gauges not over pressure the gauges Do not exceed 1500 psi for 917 2000 psi for 918 safety limit Do not shift between pressure and vacuum mode while the pump is under pressure Open the vent valve as well as the bypass valve before switching between vacuum and pressure modes Do not over tighten gauges or connectors Lightly hand tight is sufficient Store the pump in a dry non corrosive environment Additel is not responsible for problems or damage resulting from improper use or operation of the equipment Specification Pressure range 917 4 psi 0 95 bar vacuum to 1000 psi 70 bar positive pressure 918 4 psi 0 95 bar vacuum to 1500 psi 105 bar positive pressure Temperature 0 50 Humidity lt 85 RH i 2917 918 Fine adjust 10 Pa 0 1 mbar Maximum pressure 917 1500 psi 105 bar Pneumatic Pressure Test Pump User s Manual 918 2000 psi 140 bar Version number 1307V01 Pressure media Air Size Height 5 5 140 mm Base 12 4 315 mm x 7 8 198 mm Weight 5 7 Ib 2 6 kg Remark If local atmosphere pressure is 1 bar the vacuum can reach to 0 95 bar If local atmosphere pressure is P the vacuum can reach to 0 95P Configuration amp Air routine 1 Pressure lever for pre pressurization 2 Handle 3 1 4 NPT plug 4 Release valve clockwise to close counterclockwise to open 5
