Determine that you have all of the parts as per the above packing list. The upstand
comes as a standard length of 6ft.
1.
Assume a suitable fixing position for the footplate and fix the footplate to
the floor. We recommend the foot is orientated towards the chair. (Fig.1)
NOTE: It is the responsibility of the installer to ensure correct and adequate
fixings. If you are unsure you should seek professional advice from someone with
a structural knowledge.
2. Insert the upstand into the floor mount (Fig. 2 & 3). Turn the upstand so
that the protruding cable is pointed towards the chair.
3. The upstand can then be tightened into the footplate using the 8nr grub
screws on the sides of the collar (Fig. 4).
4. Slight vertical adjustments can be achieved by adjusting the grub screws
in/out to push the upright to ensure the upstand is on a true vertical plane.
If an uneven floor means that there is not enough tolerance to achieve
vertical plumb, then it may be necessary to pack the footplate.
5. The spigot on the primary arm should be lightly greased and offered to the
top of the upstand. Make the electrical connection and fit the arm system
into the top of the upstand (Fig. 5).
6. Lightly grease the spigot of the dental head and offer to the end of the
spring arm, following the instructions for fitting the lighthead on the
previous page (Section 4.2.6).
7. Ensure correct movement through all motion of the arm.
8. Fit the wire from the bottom of the upstand to the transformer. If possible,
locate the transformer underneath the chair / spittoon.
9. Wire the transformer into supply, apply power to the transformer and test
the light.
