em.tube is designed to efficiently pipe natural
daylight into a windowless or low light room. Please
note, installing the em.tube to provide additional
daylight in a room that has large windows or patio
doors, may have little effect on overall illumination.
Please read this installation guide carefully
before beginning your installation.
Contact your supplier if you are unsure about
anything involved.

Preparation & Advice
Carefully remove the em.tube and the pipes from
their respective packages and confirm that the
correct model and any optional components
ordered have been delivered.
In the event of any damage or short delivery please
contact your supplier immediately.
Ensure that the position you are fitting the roof unit
is directly above where you want light diffuser inside
room, The tubing should be as straight as possible,
avoid angles and bending the Tube as this will
impair the light transmission.
Other factors should be considered i.e. the direction
in which the Roof dome is facing. North facing roof
surface is not recommended, south facing surface is
optimal.
If your roof is facing west or east you will have more
light in the morning or in the afternoon. Avoid
overshading of tall buildings, trees etc.
We suggest you fit the largest size unit as possible
even if this means trimming out one of your rafters
and ceiling joists, in the long term you will have the
benefit of a brighter area inside.

Installation
1. Remove roof tiles approx. 1m and cut hole in roof
to suit size of em.tube.
2. Cut hole in felt to match the diameter of tube you
are fitting.
Cut tile baton also to Tube size
3. Join the two ends of the top reflector ring
together with aluminium rivets or stitch screws
provided. Remove protective plastic from the
tube.
4. Fit the upper rigid section into the bayonet
fitting of the Roof unit , from the underside,
ensure that you rotate the tube into position.
5. Where passive ventilation is required, replace the
blank tabs on the underside of the dome with
the perforated tabs provided.
6. Place the roof assembly onto the roof tile batons.
The upper end of the flashing unit should be
under the roof tiles above. The bottom of the unit
with the lead attached should be on top of the
tile below.
Secure the roof unit to the batons by placing
25mm galvanised nail into roof batons and
bending them over edge of the flashing unit. Do
not puncture the em.tube tray.

Installation of the Pipe Assembly
Ensure that you are cutting the hole in the correct
position and that there are no obstructions in the
attic, such as pipe work or electric cables.
1. To adjust the angle of the elbow adaptor rotate
the two sections in opposing directions until the
required angle is achieved.
2. Depending on the location of the roof part in
relation to the ceiling diffuser position, you may
have to fit lengths of pipe onto the top ring using
the 45° angle adaptor to bring the run into the
vertical, just above the ceiling diffuser.
3. Fit lengths of 625mm or 1250mm lengths of pipe
sections as required, Trim to required length then
join two ends together with rivets provided.
! – As each length of pipe is completed,
remember to remove the protective film
from the inside of the pipe, but keep the open
end of the pipe protected against dust and
fingerprints.
7. Replace roof tiles over the roof flashing plate
ensuring that the foam weathering strip is
covered with the tiles, it may be necessary to cut
the roof tiles to suit.
It is good practice to render the edge of the roof
tiles that are sitting on the em.tube flashing
with sand and cement.
4. Wrap all joints with aluminium tape provided,
this will further strengthen the system and
prevent flies entering into the pipe through light
leakages.

5. Cut an appropriately sized hole in the ceiling
using the template provided. Fit the ceiling
frame into the ceiling.
6. Secure the ceiling frame with the long screws ,
place the plastic retainers to the screws from the
other side of the ceiling.
7. Discard the inner white plastic retainer ring as
this is not required on the rigid version. From
inside the room push the aluminium ring
through the ceiling opening and sit it on the
ceiling frame. The aluminium ring then needs to
be fitted inside the lower rigid section, (which
may need cutting as necessary) and riveted.
This is then attached to the ceiling frame up
stand with the bright zinc 20mm self tapping
screws and spacer brackets.
8. Offer the ceiling diffuser up to the ceiling frame,
align the magnets in the ceiling diffuser with the
connecters in the ceiling frame. It may be
necessary to rotate the diffuser to the right or left
to achieve a good connection.
Where passive ventilation is desired, via the
Tunnel, fit the 10 mm spacer magnets to the
ceiling frame before attaching it to the ceiling.
Ensure the diffuser panel is smooth side up i.e.,
prismatic side facing downwards to throw the
light.
