Concealed Wiring Installation
1. Switch off the mains power
You will be installing the Thermorail as part of a high voltage mains electrical circuit.
To ensure your safety and to protect the Thermorail, switch off the mains power
before you start the installation. Please ensure that means for disconnection are
incorporated in the fixed wiring in accordance with the wiring rules.
2. Install the transformer
The transformer is to be installed in the ceiling or the wall cavity no further than 2m
from the rails and needs to be connected to the mains power supply in accordance with
current local building regulations. If mounting in the wall cavity the transformer must be
behind an access plate or a timer/switch to enable access and the transformer must
have ventilation.
3. Install two wall brackets
Measure and mark out the bracket positions making sure they are level. Drill a 6mm
hole for each of the two wall brackets and an extra hole for the cable at the wiring
point and insert suitable wall plugs. Fix the two mounting brackets in place using a
screwdriver and screws.
4. Electrical Connections
Ensure your electrical supply is switched off. Push the cable through the hole in the wall
bracket and connect to the transformer previously installed (refer to the wiring diagrams
opposite). When installing multiple of the Thermorail Vertical Rails it is recommended
that each rail is connected to its own individual transformers. Multiple rails connected to
individual transformers can be wired to a single timer/switch and must be wired in
parallel.
5. Fix Thermorail to the wall
Fit the Thermorail to the mounting brackets installed on the wall. You may need assistance
to hold the rail in place. Tighten the grub screws on the two wall mount arms using the
allen key provided.

WARNING:
This is a 12Volt heated towel rail and MUST be wired to a transformer
(supplied). Connecting directly to the mains power supply will cause irreparable damage
to the element and the element cannot be replaced.
