Do’s & Don’ts
Install the Warmup Heated Towel Rails in line with these
instructions� The towel rail is designed to warm towels only
and not provide primary heating�
Ensure that the control card at the back of the manual is
completed and fixed at the consumer unit along with any
plans and electrical test records as per the current edition of
BS 7671�
Install the towel rail at least 600 mm above the floor in order
to avoid a hazard for very young children�
Ensure that all electrical connections conform to the current
BS 7671 Wiring Regulations� Final connections to the main
electricity supply MUST be completed by a Part P qualified
electrician�
Ensure that the power supply to the towel rail is isolated
before any installation or maintenance�
Attempt a DIY repair if you damage the heated towel rail,
contact Warmup for assistance�
Pull on the power supply cable as it may cause damage to the
towel rail�
Attempt cleaning the towel rails using abrasive or chemical
cleaners as these will damage the surface finish over time, use
a so clean cloth and a non abrasive cleaning agent�
DO
DON’T
WARNING: This appliance can be used by children aged from 8

Install the RCD
Install a dedicated 30 mA RCD or use an existing RCD. No more than
7.5 kW of heating may be connected to each 30 milliamp RCD. For
larger loads, use multiple RCD’s.
NOTE: In the case of bathroom installations, electrical regulations
prohibit the installation of Mains Voltage products such as
thermostats, contactors, fused spurs, isolators or junction boxes,
within Zones 0 or 1.
Warmup Heated Towel Rails have an IP rating of IP55 and are suitable
for installation within Zone 1, Zone 2, Zone 3 or outside of any Zones.
All electrical connections must conform to the current BS 7671
Wiring Regulations. Final connections to the main electricity
supply MUST be completed by a Part P qualified electrician.

•Ensure that the wall you
intend to mount the rails onto
is strong enough to hold the
weight of the towel rail.
• When you intend to mount
the rails to stud walls, fixings
must be made into the studs
or noggins.
•When you intend to mount the
rails to masonry walls use the
wall plugs supplied.
•Cables back boxes etc.,
will have to be chased into
masonry walls.
IMPORTANT: DO NOT mount
towel rails to plasterboard alone
as they will not provide enough
support.
Before you begin
•Mains voltage cables installed
within a wall must be fixed
at least 50 mm from the
wall surface or occupy the
horizontal and vertical safe
zones in accordance with
BS 7671.
Step 2 -
Layout Planning
In order to avoid a hazard for very young children, heated towel rails
should be installed so that the lowest heated rail is at least 600 mm
above the floor.

The Warmup Heated Towel Rails electrical connection
must conform to the current BS 7671 Wiring Regulations.
Final connections to the main electricity supply MUST be
completed by a Part P qualified electrician.
• The supply should be
on a circuit protected by
a maximum 5 amp fuse
or circuit breaker. It is
recommended that the
heated towel rails supply is
fitted with an in-line isolator
to allow it to be independently
isolated. Please see Page 6 for
correct zoning.

Troubleshooting
HEATING ISSUE 1 - The towel rail does not heat up.
Instructions which are shaded must completed by a qualified
electrician.
END USER ELECTRICIAN
With the towel
rail switched
on allow 3 - 5
minutes for the
towel rail to
heat up. Can
you feel heat
coming from
the towel rail?
Measure the
resistance of the
towel rail. Is the
resistance in line
with the values on
Page 19.
If you can feel heat
on the towel rails
surface then it is
working. Please see
the Performance
Troubleshooting
Guide.
Are the wiring
connections
from the towel
rail to the power
supply secure?
Rewire the
towel rail to the
power supply.

HEATING ISSUE 2 - The towel rail trips the RCD
ELECTRICIAN
Towel Rail has
been damaged
and may need
replacing.
Conduct a resistance test on
the towel rail. Do the figures
match the control card and/or
reference resistance bands?
Are the connections from towel
rail to power supply secure?
Rewire the towel rail
to the power supply.
Test RCD
NOYES
YESNO

16
The heated towel rails must be
tested before they are installed
and again before final connection
is made. The resistance (ohms) of
each heater should be measured.
You should carry out the following
tests and should expect the results
detailed below:
• Heated Towel Rail Resistance Test
Set a multimeter or ohmmeter to record resistance in the range of the
heated towel rail. Measure the resistance across the live (brown) and
neutral (blue) wires. Ensure the measured resistance is in line with
Resistance values for the rail being tested.
Record the readings on the control card in line with the installation
procedure.
• Earth Fault Check
Set a multimeter or ohmmeter to record resistance in the range of
1MΩ or greater if available. Measure the resistance across the live
(brown) and neutral (blue) wires to the earth (green/yellow) wire.
Ensure the measured resistance is showing as greater than 500MΩ or
infinite if the meter cannot read this high.
Insulation resistance test
Set an insulation resistance tester to 500VDC. Measure the resistance
across the live (brown) and neutral (blue) wires to the earth (green/
yellow) wire. Ensure the measured resistance is showing greater than
500MΩ to indicate a pass.
