Functions and Applications

  1. Connect hoses to test connections – red high pressure hose upstream, green low pressure hose downstream.
  2. Open valves on device being tested and read differential.
  3. Upon completion of test close valves, disconnect hoses and store them in test kit case.

NOTE: The 841 Test Kit is equipped with inline 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.
