4.1.5 Downtube adjustment and installation
The downtube provided will be either 1m as standard or 2m (optional) maximum with
a boot on the bottom. It is Daray’s recommendation that the bottom of the
downtube is approximately 1900mm from the floor once installed.
Measure the distance from the ceiling plate to where the bottom of the downtube
will sit. Mark and cut the downtube. When cutting the downtube to length it is highly
recommended that you push the wire back inside the downtube so that you don’t cut
through it.
The downtube should be cut to length on site to suit the particular
ceiling height and application.
Once the downtube has been cut to length it will be necessary to de-burr
the end of the tube, as this can help prevent damage to the cable.
Note, when installed the downtube must leave clearance above the
ceiling mount plate to prevent the cable being trapped.
Loosen the clamp on the top of the ceiling plate and remove the safety bolt. Insert
the downtube and adjust the boot of the downtube to be facing the examination
area.
Note: For suspended ceilings, there is a small suspended ceiling trim and rubber
retaining band included. For units being installed into an open ceiling there is a full
size ceiling mount cover available as an optional extra from Daray.
NOTE: For suspended ceilings cut a clearance hole in a ceiling tile and slide this over
the top of the downtube and suspended ceiling trim before attaching to downtube to
the ceiling plate.
