Upon completion of test close valves, disconnect hoses and store them in test kit case. NOTE: The 841 Test Kit is equipped with in line filters near the ends of the hoses. If the gauges respond slowly to changes in the differential pressure the filter elements may be partially plugged. To remedy this, unscrew the two halves of the filter housing and remove brass filter element. It may be cleaned by flushing with mild detergent and water. If, after reassembly this has not satisfactorily improved the response time a replacement filter element kit #98008 should be installed. MODEL 841 TEST KIT SCHEMATIC DIAGRAM

“This test kit is a previously used tool that has been well cared for. The only sign of usage is on the knurled hose ends, very slight evidence of use. There were two owner markings on the case with magic marker, they have been removed but may still show faint outline. The mounting bracket is still tight and intact no markings at all looks new. The dial is clear and unbroken. Very nice clean used tool.”
