1. Warnings and cautions Low pressure gauges can very easily be over pressured if not careful Please take caution when applying pressures Do NOT exceed the safety pressure limit 3500 psi 235 Bar This pump is not designed to be used in explosive or corrosive environments Do not switch between pressure and vacuum mode under pressure Make sure you have vented the pressure and opened the isolation valve before switching to vacuum Over tightening connectors may cause damage Pump should be stored in a dry clean environment Additel is not liable for any safety problems or damages caused by misuse or incorrect operation Do NOT hold pressure above 1000 psi for more than 4 hours All moisture and contaminants should be cleaned out of the liquid isolator before creating a vacuum This is accomplished by venting the pump when at high pressure For the least risk in contamination of the reference gauge the DUT should be installed to the pressure port which is closest to the vent valve Specification Pressure range 95 vacuum to 3000 psi 200 bar Based on an atmospheric pressure of 1 bar Temperature 0 to 50 32 to 122 F Humidity lt 85 RH Adjustment resolution 0 001psi 0 1mbar 10 Pa Overpressure Safety Limit 3500 psi 235 bar Pressure media Air Weight 14 4 Ibs 6 5 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 reach2. to 0 95P bar AD T 9 9 0 Air routine Pneumatic High Pressure Test Pump User s Manual Version number 1410V03 Please download the latest version from Configuration amp Size 1 Quick connector 2 Hand pump 3 Pressure vacuum P V selector Positive pressure pull it out Vacuum push it in Do NOT switch while unit is under any pressure 4 Pressure Vacuum lock 5 Fine adjust handle Turn Clockwise to increase pressure 6 Maintenance cleaning port 7 Isolation valve isolates the calibration volume from the hand pump and check valve 8 Vent valve clockwise to close counterc lockwise to release pressure 9 Vent port KEON Troubleshooting The isolation valve is not open Open the isolation valve A Vent valve is not closed Close the vent valve B The O ring seal is loose or damaged Replace O ring seal C P V selector is in the wrong position Pressure Pull P V selector out Vacuum Push the P V select or in D Internal tubing is dirty Disassemble and clean Request diagram A The isolation valve is not closed Close the isolation valve B The gauges are not tightened Tighten the reference gauge and or the gauge under test C The O ring seal is aged or frayed Replace O ring seal D The connector type is mismatched to the gauge pressure port Use the correct adaptor E Air route is blocked dirty Pressurize to high pressure and releas
