mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning
use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance.
Cleaning and user maintenance shall not be made by children without supervision.
All-pole disconnection from the supply is required, incorporated in the fixed wiring. Switches intended to ensure all-pole
disconnection must be directly connected with the supply terminals and must have a contacts distance of at least 3 mm
in each pole.
Electrical towel rail must not be installed with the MOBUS regulating box located at the top. This can seriously damage
the control box and create a dangerous situation with a risk of fire.

The electricity supply must be adequate to support the required power.
Protect the electricity supply with an RCCB (Residual Current Circuit Breaker) device.
All metallic parts of the electrical towel rail fitted with MOBUS and powered must not exceed the temperature limits
according to the applicable standard EN 60335-2-43 also in case of broken capillary thermostat control that
continuously powers the heating element.
MOBUS yellow/green earth wire must be connected to the corresponding yellow/green ground wire of the electricity
supply at the mains. (THIS PRODUCT MUST BE EARTHED)
Don’t use the MOBUS regulating box to lean the electrical towel rail on the floor as you can damage the plastic and
water can penetrate inside with a risk of electrical shock.
The electrical heating element must be permanently connected to a suitable electricity supply by way of the cable
provided. This should be via a fused spur in accordance with the IEE Wiring Regulations (BS7671). If sited in the
bathroom, the Fused Connection Unit must be located out of reach of persons using the basin, shower or bath. If in
doubt, consult a qualified electrician.
Connect the MOBUS control unit to the mains using a BS Fused Connection Unit.
The Fused Connection Unit should be fitted with a 5 Amps fuse to BS1362.
TOWEL RAIL INSTALLATION WARNINGS
•
The Towel rail has to be mounted parallel to the wall using the brackets recommended by the towel
rail manufacturer. The distance between MOBUS and the wall must be between 60 and 90 mm (Fig. 2).
In order to avoid a hazard for younger children, the electrical towel rail should be installed so that its
bottom part is at least 600mm above the floor according to EN 60335-2-43/A1.
•
MOBUS must be fitted to the towel rail before mounting the rail to the wall.
•
Wrap a small quantity of PTFE tape around the MOBUS heating element thread and the
T-piece thread (in case of Dual Fuel installation).
•
Make sure that the towel rail is fitted with a component (like 3BAR Valve) which limits the risk of
excessive pressure.
