Fitting the Membrane/s
Ÿ
Remove the membrane from packaging.
It is important not remove the white sticky tape or the plastic wrapping from around the membrane.
Ÿ
It is recommended that both the two small black o-rings and the large black O ring are given a VERY light smear
of petroleum jelly such as Vaseline to make installation easier.
Ÿ
Holding the housing, unscrew the housing cap complete with pressure gauge and insert the membrane with the
two small, black o rings first. It will stop at the large black gasket seal located on the outer edge of the membrane
material. Push the membrane into the housing sometimes it’s a tight fit so push with adequate force. You will feel
it “seat” into the housing.
Ÿ
Once the membrane is seated properly, make sure the housing “o ring” is fitted and moist. Then screw the
housing cap onto the housing.
