1. Securing Screw Allen M2 5 Now you can unfasten the filter housing using a 17 spanner wrench Please make sure that a secondary O ring is located along the threading This O ring has to be present during reassembly of the unit Should this O ring somehow be lost air tightness of the unit cannot be guaranteed The unit will possibly suck in outside ambient air during operation causing an overflow condition during detection of fine leaks Use air from a compressor with an air stream direction inverse to the suction direction blowing vigorously through the sintered filter in order to properly clean it Direction of Cleaning Upon completing the last steps reassemble all of the parts previously taken apart in reverse order Check for proper air tightness of the GM 5 by blocking the feed opening of the intake nozzle while operating the unit in above ground detection mode During this test the display should indicate a flow rate of 0 0 l min Should this not be the case please recheck the intake for unobstructed flow 37 Operating instructions GM 5 NG SC UTZ MESSTECHNIK 4 3 Changing accumulators Attention The accumulators may not be removed or charged in an area with explosion danger Attention Always turn the instrument off to change the accumulators Attention To preserve the declaration of warranted explosion protection only batteries officially endorsed by Schutz Messtechnik Measurement Technologies sh2.
