Safety and care
information
ThermoSphere Towel Bars should be
connected to the electrical supply by a
qualied electrician and in accordance
with current local regulations.
We recommend that the towel bar is
installed with the bottom bar at least
600mm from the oor and with a
300mm clearance from permanent
xtures.
Recommended spacing between bars
is 150mm
ThermoSphere Heated Towel Bars can
be xed onto timber stud, steel stud or
masonry (solid or cavity) walls.
Stud walls require noggins at the correct
position for all xings and if the exact
position cannot be determined early in
the job, we recommend using noggins
covered with 18mm construction ply or
OSB covering a larger area.
Fixing to plasterboard or cement
sheeting alone is not recommended and
will not hold long term.
ThermoSphere SE Towel Bars are
designed to be installed BEFORE TILING
and as such it is imperative that the
xing spigot and/or mounting system is
installed perfectly level. We recommend
using a laser level and checking the level
periodically throughout installation.
Towel bars are 12V SELV (safety extra
low voltage) and can be installed in
bathrooms.
Ensure any controls used are installed in
correct zone according to the IP rating
of the control
Ensure that your towel bar is protected
by a suitably rated RCD
Do not use the towel bar to hold
towels or other articles that have been
in contact with oil, petroleum based
products or dry cleaning uids
This appliance is intended to warm and
dry towels not heat spaces
Do not immerse your towel bar in liquid
Ensure the transformer is located no
further than 2m from the ThermoSphere
Towel Bar
Ensure the transformer is accessible and
has adequate ventilation
Care information
The Stainless Steel nish of your
towel bar is hard wearing and easy to
maintain. However any harsh scrubbing,
scratching or acid based cleaning
products will damage the surface of
your towel rail.
Clean with a soft cloth dampened with
warm and warm soapy water only. Dry
immediately for the best nish.
Max weight warning
ThermoSphere SE Towel bars are
designed to hold towels only, and must
not be subjected to excessive forces over
10kg and must not be climbed on or
used as support rails.
This can result in injury and can cause
damage to the towel bars which is not
covered under the guarantee.

Key considerations
Fixing spigots must be installed before tiling!
You MUST make sure xing spigots are level!
Low voltage transformers
Max tiling depth is 35mm
Use the right xings for your wall substrate
SE Towel Bars xing spigots are designed for installation before
tiling. You must install the xings spigots and run cables before
you tile the wall. There is no option to install SE Towel Bars on
top of a tiled wall.
Because the xing spigots are installed behind the tiles, you
have to take extra care to make sure they are installed level. We
recommend using a laser level throughout the process to check
the towel bars are nice and level!
SE Towel Bars are 12V DC and there is no polarity. You must
install a suitably rated 12V transformer between the towel bar
and the 230V supply. You can connect multiple towel bars to
one transformer in parallel, up to the maximum load of the
transformer. The transformer should be somewhere accessible to
facilitate replacement.
The maximum depth of the tiled wall layers that will be situated
over the xing spigot is 35mm. This includes any boards, tile
adhesive and the tiles. Limiting the tiling depth ensures that
there is enough spigot protruding from the wall to achieve a
good, strong xing to the towel bar.
We recommend that you x SE Towel Bars to a solid wall, such
as a brick/block cavity wall, a secure timber noggin within a
cavity wall or a plywood/OSB panel. Use xings that are suitable
for the type of wall you are xing to. We do not recommend
xing directly to plasterboard or tile backer boards as this can
cause the xings to move over time and result in loose towel
bars.

Installing single bars
(No mounting system)
Loosen the grub screws with
a hex key.
Drill a hole in the noggin
big enough to pass the
connection cables through
(22-25mm).
Remove the spigot and dress
ring and keep safe to one side.
Feed the connection cables
through the hole and up to a
12V transformer.
Ensure the spigot is level and
mark xing holes. A laser level
is recommended.
Pull the connection cables
through the spigot and a
screw in the top right corner.

boards to the wall ush with
the front of the mounting
system. Follow the board
manufacturer guidelines.
Drill a hole and feed the
connection cables through
the wall cavity to a 12V
transformer. Do not drill the
cables!
Cut a tile backer board to t

Cut a 30mm hole in the
tile that is situated over the
mounting spigot. Use tile
adhesive to tile the wall as
normal.
Once tile adhesive has dried
you can t the towel bar. Place
the dress ring over the spigot.
Plug in the red and blue bullet
connectors (12V no polarity)

wall cavity.
You can install up to 7 SE
Towel Bars on one mounting
system. The mounting system
makes aligning and levelling
multiple bars quick and easy.

Example wall build up
The image below shows how a full wall build up looks with a
mounting system, tile baker boards, tiling and dress rings.
IMPORTANT! The thickness of all layers that are installed over
the xing spigot mounting plate must not exceed 35mm.
In this example the wall build up is 20mm and includes the
mounting system (2mm), adhesive (6mm) and tile (12mm).
If you don‘t leave enough spigot protruding from the wall, you
won‘t be able to secure the towel bars properly!

Cable management
The mounting system makes cable management easy. You can
run the cables behind the mounting system and drill a hole at
the top to pass them into the cavity and up to your wiring point
All cables
run up to
wiring point
If you‘re installing on a solid brick/block wall you will need to
chase a channel for the cables.
Alternatively, you can use the multiple mounting systems to run
the cables behind and cover the wall with a backer board before
installing tiles. This avoids the need to chase cable channels.

Wiring schematics
All electrical work must be compliant with the relevant local
regulations and carried out by a professional electrician. Isolate
the electrical supply before you start.
ThermoSphere SE Towel Bars are 12V SELV and can be
installed safely anywhere in a bathroom. All electrical circuits in
bathrooms must be protected by a suitably rated RCD.
