Operating filter membrane holder / Removing filter membrane
The operation of the filter membrane holder changes depending on the
version and model. Descriptions of the versions are given below.
Filter membrane holder with union nut
The thread on the union nut means that the lower part (67.2) of the filter
membrane holder is pressed against the upper part (67.1) preventing
leakage and ensuring that the membrane works properly.
To close the filter membrane holder, lift the lower part (67.2) up to the upper
part and tighten the union nut (67.1) clockwise. Do not use a tool.
The filter membrane holder is opened by turning the union nut (67.1) counter-
clockwise.
