BEFORE YOU INSTALL – please read
Sirius warranty covers only Sirius product. If you choose to install a non-Sirius branded accessory
such as flexible ducting, Sirius will only warrant the hood and motor. If installation is found to be the
cause of failure or issue then charges will apply for service and parts.
Flexible ducting is not permitted under any circumstances. Flexible ducting has been found to
increase noise levels, increase vibration and reduce airflow.
Sirius Semi-rigid or solid ducting can be used in lieu.
There is a range available to suit any application.
Ducting available at www.siriusbrand.com
A reduction in the duct diameter from stated ducting size will void warranty.
If you are in doubt about the ducting, please contact Sirius on 1300 762 219 prior to installation

Before proceeding with the installation of the ceiling cassette, please thoroughly inspect the entire unit
(including the motor) for any damages, including all of the electrical connections. If any damage is found,cease
installation and report it immediately to the retail partner that the cassette was purchased from.
Reduction of the ducting diametrer will void the manufacturer warranty as it will severely affect the performance
of the motor and may cause damage with prolonged usage.
Use ducting approved by standards enforced, see www.siriusbrand.com for details for approved ducting. The
manufacturer will not be deemed responsible for air capacity and noise problems caused by failure to comply
with the above and no warranty on the product will be provided.
FAILURE TO INSTALL THE SCREWS OR FIXING DEVICE IN
ACCORDANCE WITH THESE INSTRUCTIONS MAY RESULT IN
ELECTRICAL HAZARDS OR ELECTROCUTION.
The cassette requires one 10AMP GPO located inside the ceiling cavity
to power both the lighting and the motor.
The ceiling cassette is designed for a ceiling height of up to 2700mm high.
• SLT960 EM ONLY
Installation of the ceiling cassette can either be installed 50mm proud mounted or 260mm proud with the
additional purchase of the stainless steel proud mount kit (SPS-76105980960)
• Only use Sirius Ducting with a maximum length of 7 metres & minimum of 2 metres from the outlet collar
on the cassette to the motor location.
• Limit the number of elbows in the ducting, since each 90 degree bend reduces the air capacity by 1 lineal
metre (e.g. if there are 2 x 90 degree bends, the maximum duct length should not exceed 5 metres.)
• Avoid abrupt changes of direction where possible, bends of more than 90 degrees should be avoided at all
costs.
• Use of 150mm ducting is applicable for SLT958 models only, 200mm ducting is applicable for SLT952 /
SLT960 / SLT968.

As every installation will differ slightly depending on the ceiling cavity of the dwelling,
this installation shall be used as a guide only.
NOTE
• These cassettes are held in place with the use
of the 4 x 250mm threaded bolts. Using the
measurements in the Fig. 4 line drawings ensure
that there is timber framework (not supplied) inside
the cavity to support the weight on the cassette.
Please refer to each individual measurement for
the exact location of the mounting holes or take
a physical measurement of the location when the

INSTALLING THE TIMBER SUPPORT BEAMS
• After running the timber support beams in the cavity above, pre-drill 4 x 8mm holes through the timber
and pass the 4 x 250mm bolts through them, ensuring that the larger washer is on the INSIDE OF THE
CEILING CASSETTE. (Fig. 5a)
• Lift the cassette into position and ensure that
the 4 x 250mm bolts pass through the mounting
points. Fit the larger diameter washer first and
then wind the wingnut up thr thread and tighten
the cassette into position. These will enable you
to flush the unit tight with the ceiling (Fig. 5a).
• After screws are fitted, replace the panels that
were removed during Step 1d by reattaching the
hinges and reattaching the light cable.

OPERATION MODE
Standard configuration:
Standard configuration requires all rangehood radio
control systems to be provided with the same
transmission code. In the event two rangehoods are
installed in the same room or nearby, each system
may affect the operation of the another. Therefore,
the code of one radio control system must be
changed.
Generating a new transmission code:
The radio control system is provided with preset
codes. Should new codes be required, proceed as
follows: Press simultaneously buttons:
for two seconds. When LEDs are on, press buttons:
(within 5 seconds). The LEDs flashing 3 times
indicate the procedure is completed.
WARNING! This operation deletes permanently
the preset codes.
Learning the new transmission code.
Once the transmission code is changed in the radio
control unit, the electronic central unit of the cooker
hood must be made to set the new code in the
following way:
Press the main power-off button of the hood and
then restore power to the electronic control unit.
Within the next 15 seconds, press the Light Button to
synchronise the central unit with the code.
Reset of the Factory configuration:
To restore the Factory configuration, follow the
procedure described below: press simultaneously
buttons:
for 2 seconds. When LEDs light on, press buttons:
(within 5 seconds). LEDs flashing 6 times in-dicate
the procedure is completed.
