FILTER ELEMENT REPLACEMENT
•
Where appropriated, close shutoff valves at gas inlet and outlet
•
Depressurize the housing, this can be accomplished by pushing the test button on the BEKOMAT® drain installed
on the bottom port.
•
Unbolt top lid. You can use the last flange screw as a pivot. The lid is then simply turned aside to provide full
access.
•
Subsequent to the loosening of two nuts and a slight turn in clockwise direction, the filter elements, along with
the tie rod unit, may be completely removed from the housing.
•
Unscrew the filter elements counter-clockwise from the tie rod unit.
•
Replace the O-ring of the tie rod unit to ensure proper seal to the filter plate.

Apply torque in 20% (1/5) steps of required final torque, loading all bolts at each step before proceeding to next
step. Refer to torque values on page # 12
•
Tighten bolts in sequential order at each step until final torque is reached. Refer to torque valves located on page
