DO

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�

DON’T

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�

Zone Chart

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.

6

Step 2 -

Layout Planning

Before you begin

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.

IMPORTANT: DO NOT mount towel rails to plasterboard alone as they will not provide enough support.

• 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.

• 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.

should face the floor when the towel rail is mounted on the wall.

Step 3 - Mounting the Rail Ladder Rails

3

• Install the remaining 2 legs

(1A) to the towel rail body as shown in Step 2.

• With all 4 legs secured to the

towel rail body, install the wall mounts (6) into each leg using the grub screws (3).

4

• Attach the final leg (1B or

1C), for exposed or concealed

wiring, to the towel rail body using the grub screws (2) as shown.

65

• Use a tape measure to

measure the centre to centre distances between the wall mounts (6) which are secured in each leg and concealed (7) or exposed wiring (8) wall mounts.

7

• Mark the measurements taken

in the previous step on the wall of your intended towel rail location keeping in mind that the lowest rail should be at least 600 mm above the floor level.

• Ensure the markings on the

wall are level.

8

• Drill 3 holes in the wall for

each of the 3 x wall mounts

(6).

NOTE: For exposed wiring drill

a 4th hole of equal size.

For masonry walls gently tap wall plugs (4) into the holes using a hammer.

9

Step 3 - Mounting the Rail Ladder Rails

9

• Remove the wall mounts

x 3 (6) from the legs (1A).

• Insert the mounting screws

(5) through the wall mounts

and secure to the wall as shown ensuring that they sit flush with the wall.

NOTE: For exposed wiring,

install exposed wiring wall mount (8).

11

• Conduct another resistance

test before mounting the towel rail to ensure it has not been damaged and record in the control card.

10

• Drill a larger 4th hole for the

concealed wiring leg.

• Remove the concealed wiring

wall mount (7) from the leg (1C).

• Apply grab adhesive to the

wall mount thread and press into the drilled hole until it sits flush with the wall.

12

• Position the rail against the

wall and insert the power supply cable through the concealed wiring wall mount (7).

10

• Place the rail onto the wall

mounts (6) and secure by tightening the grub screws (3) as shown.

unscrewing the grub screw (2) located at the bottom of the rail.

7

• Drill three holes into the

previously marked positions, two for the mounting screws and one for the supply cable

NOTE: For masonry walls gently tap wall plugs (3) into the mounting holes using a hammer.

Make Electrical Connection

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.

1

• 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.

Warmup Heated Towel Rails can be connected into the rooms lighting circuit, enabling the towel rail when the lights are switched on.

Alternatively they can be controlled by an independent controller that provides power on demand.

How to test the heated Towel Rail

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.
