Slide the gland onto the gland stem, hold the
stem between the thumb and forefinger of
your left hand and roll the gland along
the side of your right hand forefinger.
As you roll it, work the gland
along the whole length of
the stem.
This will remove any
particles of dust
inside the gland.

Fit one 7mm O ring into
the groove in the bottom
of the gland.

Locate the underside of the top plate.
The underside is the side with the countersinks on the two holes as shown in the diagram.
If you have solar (acrylic) or polished (stainless steel) plates you will need to remove the
protective film from the top plate now. Once you have removed the film try to handle the
plate by its edges, this will minimise fingerprints. Solar (acrylic) plates have protective film
on both sides, polished (stainless steel) plates have protective film on one side only. Black
and blue (aluminium) plates do not have protective film.

Screw the gland into the top side of the top plate and fully tighten, you might need to
wrap an elastic band around it for grip. Make sure that the O ring does not become
pinched or fall out of its groove. If you have trouble with the O ring falling out you can
turn the plate upside down and screw the gland in from underneath.

Fit one 13mm O ring into
the groove in the bottom of
the cylinder.
