mounting plate. The plate has been
correctly positioned by the factory to
precisely align the holes with the glands
and pipes.
If the mounting plate is removed and re-
placed it may no longer be precisely
aligned, and the pipes may be damaged.

•Insert the longest pipe with the threaded end of the pipe pointing
towards the box, through the gland into its position (see drawing
below)
•Insert the shortest pipe with the threaded end of the pipe
pointing towards the box, through the nipple into its position (see
drawing below)
•Make sure that the pipes are fitted firmly and as far as possible
against the mounting plate
•Turn the box around and make sure that each pipe is correctly and
properly fitted
•Screw and fasten the nuts (M16) firmly onto each pipe with a 19
mm wrench
•Be sure to direct the edges on the back nut towards the mounting
plate for locking
The picture above shows the pipes correctly inserted through the
glands with the nuts fastened.

(make sure that the cable runs into
the small cable entry, and that the
cover fits perfectly over the nuts of
the sampling tubes)
•To ensure that the transparent
smoke chamber is kept in its position
(see picture), place the small bracket
on top of it, and tighten the screw.
•Fasten the top cover onto the box again, then fasten the screws.
Torque for the cover screws: 1Nm.
•When mounting the cover, ensure that there is no damages,
especially inspect the gasket and cover of the unit.
