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 as
the boards will not support the towel
bars and xings long term.
If your towel bars are going to be
installed before tiling it is imperative
that the xing spigots 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 electrical
circuit 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 bar.
Clean with a soft cloth dampened with
warm and mild soapy water only. Dry
immediately for the best nish.
Max weight warning
ThermoSphere towel bars are designed
to hold towels only, and must not be
subjected to excessive forces over 10kg.
Towel bars 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
Install spigots (if using) before you tile!
You MUST make sure xing spigots are level!
Low voltage transformers
Max tiling depth is 45mm
Use the right xings for your wall substrate
DE Towel Bar xing spigots are designed for installation before
tiling. You must install the xing spigots and run cables before
you tile the wall. Each towel bar comes with xing studs for
installing over a nished tiled wall.
Because the xing spigots and mounting systems are installed
before you tile, you need 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!
Towel Bars are 12V 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 and the total load of the bars should
be between the min and max rating of the transformer. The
transformer should be somewhere accessible to facilitate
replacement.
The maximum combined depth of the wall layers that will
be situated over the xing spigot is 45mm. This includes any
boards, tile adhesive and 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 our 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 results
in loose towel bars.

Installing over nished tiles
With supplied mounting studs
Measure and mark out xing
centres using a laser to make
sure they are level.
Screw the second xing stud
to the wall using a suitable
xing for the type of wall.
Screw the rst xing stud to
the wall using a suitable xing
for the type of wall.
Check you‘re happy with the
level by locating the towel bar
over the xing studs.
Drill a 10mm hole in the wall
above the right hand xing
stud.
Check the position of the
second xing stud using the
towel bar and a laser level.
Remove the towel bar from
the xing studs and keep it
clean, safe and protected from
scratches.
Run the 2m connection
cables into the wall cavity
and connect them at the
transformer location.

Mark out the xing positions
for the mounting spigots. A
laser level is recommended.
Locate the towel bar over the
spigots to make sure it ts and
that you‘re happy with the
level. Change it now if not!
Fix the mounting spigot
securely in place. Use xings
that are suitable for your wall
type.
If using tile backer board,
install this over the spigots. Do
not x spigots to XPS or tile
backer boards!
Cut away the tile backer board
to allow a recess for the cable.
Ensure the second spigot is
level with the rst and x in
position with suitable xings.
Drill a hole next to the right
hand spigot to push the cables
through to the wall cavity.
Feed the cables into the wall
cavity, run to the wiring point
and connect to a suitably
rated 12V transformer.

Fix XPS or tile backer boards
after installing the mounting
system. Do not x towel bars
to XPS/backer boards.
Install the tile backer boards
in accordance with the
manufacturer‘s instructions.
Cover the mounting systems
with mesh tape. This helps to
prevent the tile adhesive from
slipping off the steel.
Now tile the wall as normal.
Cut a hole (max 15 x 28mm)
in the tiles that will be
installed over the spigots.
Drill a hole in the wall at the

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.
If you‘re installing onto a solid brick/block wall you will need to
chase a channel for the cables or use multiple mounting systems
to run the cables behind. Cover the wall with a backer board
ush to the mounting systems before installing tiles.
