METHOD 3:
a. Attach the PI backcan to the optional pre-mount
plaster ring using the fixing points provided with the
pre-mount ring. (Fig 3).
b. Secure the wings of the pre-mount ring to a
secure fixing point using suitable fixings.
2. Attach conduit to the backcan using one of
two methods:
METHOD 1: Use the clamp at the back of the
pre-install backcan. The product will accept a
squeeze connector with a thread size of up to 22
mm. To remove the cable clamp, simply unscrew
the threaded washer (under the wiring cover) which
holds the cable clamp in place and replace it with a
conduit squeeze connector. (Fig.4)
METHOD 2: Use any of the three knock-out points
at the sides of the backcan (19 mm, 22 mm or
28 mm diameter). (Fig 5)

3. If conduit not used, run approved speaker cable
to the installed can. Terminate in the top-mounted
cable clamp or with an approved cable connector
in one of the three knock-out points at the sides of
the backcan.
4. Cut a hole in the proper ceiling location using the
supplied cut-out template (self-adhesive backing)
and a pad saw. Place the pre-install backcan over
the hole.
5. Proceed to Section 5 following on wiring and
setting up. Return to Step 6 below.
6. Slide the speaker assembly through the hole.
Turn the screws (denoted "Screw Fix") clock-

wise on the front of the speaker to extend the
mounting wings. Tighten the screws until a firm
grip is achieved.

(NOTE: Screws have a PoziDriv head; use of a
PoziDriv driver is recommended). If using a power
driver, Tannoy recommends a torque setting of
1.5 Nm. (Fig.6)
