SEM21 MOTOR
The SEM21 motor is designed to exhaust fumes and
odours silently and effectively. It must be installed on an
external wall a minimum of 500mm from the ground and
connected to the rangehood.
•
Note: the SEM21 motor cannot be installed
back-to-back with the rangehood.
•
Note: due to OH&S regulations, if the SEM21
motor is positioned higher than 2 metres from
the ground, additional servicing costs may incur.
Please note: motor must be accessible.
Note: Due to the noise of the motor itself once installed, be
sure to check that if it located close to a boundary fence
or you are in a built-up area that you have checked with
neighbours or local council regulations prior to installation.
Motor location
1. Please note that the SEM21 motor must be
installed at a minimum distance of 2 metres from
the outlet collar on the rangehood. A maximum
of 7 metres must not - under any circumstances - be
exceeded. All SEM21 motors come fitted with a 7
metre long control cable.
Installation
1. The installation of the SEM21 motor must only be
made by a qualified technician/tradesperson. Where
possible use a Sirius recommended installer (See
www.siriusbrand.com for a list under the support tab)
2. After predetermining the location of the motor, make
sure you are within the recommendations above in
regards to min/max distances. Use the supplied drill
hole template that is supplied with SEM21 motor and
drill support holes, paying careful attention to make
sure that the area behind is clear of electrical cables
and piping/plumbing. These holes are to be drilled with
an 8mm drill bit.
3. 160mm diameter hole to be cut into house for 150mm
ducting. Please note that if a solid masonary block wall
or brick wall is being used that a series of holes may
need to be drilled and then the remainder of the hole
be knocked out by hand with a hammer and chisel.
If a masonary hole bit is available, this will provide the
best result.
4. A hole must also be made to contain the plastic pipe
that the SEM21 wiring loom is fed through. 40mm hole
is required (Fig. 3). 40mm drill but required.
5. Remove the stainless steel body to expose the motor
and fixing points by removing the external screws
located on the outside of the SEM21 motor (Fig.4).
6. Run the length of semi-rigid/solid duct through the
pre-cut hole and attach to the SEM21 collar. Secure in
place with a URC-25/215 ring clamp, making sure it is
fastened tightly and will not come off. Feed the cable
from the motor through the 40mm plastic pipe at the
same time.
7. Lining up the fastening points with the pre-drilled
holes, secure the motor in place using the supplied
plastic dowels and the supplied screws.
8. Replace the stainless steel body by following the
step 5 in reverse, making sure that the holes line up
perfectly to ensure the unit is sealed correctly. Do not
silicone motor to the wall.
9. Run the length of ducting back to the location of
the rangehood and secure to the outlet collar on the
rangehood using another URC25-215 ring clamp.
10. The SEM motor has a 7 metre long cable with
colour-coded wiring. Follow the MOTOR WIRING
CONNECTION instructions on page 4 of this manual
to connect the motor to the rangehood.
11. The SEM21 motor will draw power directly from the
rangehood which needs to be plugged into a 10AMP
powerpoint located within 1 metre of the rangehood.
