Step 1 –

Electrical Supply

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: It is possible to run the demister(s) from a existing lighting circuit protected by a 30 mA RCD. It should be calculated whether or not the circuit can handle the additional load.

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.

This mirror demister has an IP rating of IP65 and is suitable for installation within 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.

Step 2 –

Layout Planning

Before you begin

Determine the location of the mirror demister, marking its intended position of the on the wall.
Also mark the demister power cable position on the wall.
If the mirror is mounted within the plane of the tiles, ensure that it is surrounded with a minimum 3 mm bead of silicone to allow for mirror expansion and contraction when heating.
If fixing the mirror to the wall using adhesive or screws ensure flexible fittings are used, either in the form of a flexible mirror adhesive or flexible bushings in the fixing holes if screwed to the wall.
The demister must not be cut, shortened, punctured or creased, however the supply cable may be shortened if required.
If the mirror is going to be mounted within a rigid (metal/ wood/moulded resin) frame it should be able to expand and contract independently of the frame.

NOTE: If using adhesive to mount the mirror to the wall ensure that it is suitable for use with heated mirror demisters. Please contact mirror adhesive manufacturer for guidance.

NOTE: Take care not to screw through the demister if mounting the mirror with screws.

Step 3 –

Apply Mirror Demister

Measure and record the resistance of the demister in the “Resistance Before” column of the control card, supplied as part of this installation guide on Page 16.
Stop installation immediately and contact Warmup if its resistance falls outside the range set out in the Reference Resistance Band table on Page 18.
Always handle mirrors with care. Lay the mirror face down on a protective soft surface.
The back of the mirror must be clean, dry and free from grease, detergents or polish.
Position the demister on the back of your mirror so that it matches the markings previously made on the wall.
Draw the outline of the demister on the back of the mirror.
Peel 50 mm off the protective backing and position it so that it lines up with your markings on the mirror back.
Press the demister into the back of the mirror smoothing out any air pockets between the demister and mirror using a soft cloth or a sponge.
Gradually remove the rest of the protective backing repeating the previous step, removing any air pockets, ensuring you keep the demister in line with the markings you made on the back of the mirror.

Step 4 –

Make Electrical Connection

The Warmup Mirror Demisters 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.

Channel out a recess in the wall for the connector block and power supply cable of the demister. This location should have been marked on the wall in Step 2
The supply should be on a circuit protected by a maximum 5 amp fuse or circuit breaker. It is recommended that the mirror demisters supply is fitted with an in-line isolator to allow it to be independently isolated. Please see Page 6 for correct zoning.
The demister is a Class II device and does not require connection to earth.

NOTE: If installing multiple heaters, they MUST be installed in parallel, DO NOT connect in series. The power rating of the circuit should also be checked to determine that the heaters will NOT overload the circuit.

NOTE: Any metal parts which are accessible and are in contact with the mirror must be earthed in compliance with BS 7671.

Step 4 –

Make Electrical Connection

The Warmup Mirror Demister can be connected into the rooms lighting circuit, enabling the demister when the lights are switched on.
Alternatively they can be controlled by an independent controller that provides power on demand.

Step 5 –

Mount The Mirror

Conduct another resistance test before mounting the mirror as described on Page 14 to ensure the demister has not been damaged and record in the control card on Page 16.
Ensure that the wall is clean, dry and flat. The mirror should be mounted in line with the mirror manufacturers instructions.
Ensure when mounting the mirror that the supply cable and its connections are not trapped behind the mirror, which would cause the mirror to be stressed or sit unevenly on the wall.
Once mounted seal around the edge of the mirror with silicone.

NOTE: Alterations or cuts are made to the mirror may cause cracking when installed in conjunction with the Warmup Mirror Demister and are not recommended. Alterations include:

A rectangular hole for a switch, outlet, or other appliance.
A hole exceeding a diameter of 2” (50mm). Common for plumbing fixtures
Inner angles cut into the mirror

Performance Troubleshooting

My mirror does not heat/demist my mirror

The demister may be installed on a solid wall which be losing heat into the wall surface behind.
If your mirror has been installed on a solid wall, ensure that a gap is left between the demister and brick, tile or cement walls to avoid heat transfer away from the mirror.

My mirror has cracked.

Old mirrors may not be suitable for use with Warmup Mirror Demisters.
Before applying a mirror demister to any mirror, its suitability with a demister should be checked with the mirror manufacturer.
Check that there is suitable expansion space around the perimeter of the mirror, that fixing are flexible, not rigid and that there are no cuts formed into the mirror which are prohibited in Step 5.

How to test the Mirror Demister

The demister must be tested before they have been installed and again before mounting the mirror. The resistance (ohms) of each demister should be measured. You should carry out the following tests and should expect the results detailed below

Mirror Demister Resistance Test

Set a multimeter or ohmmeter to record resistance in the range of the demister. Measure the resistance across the live (brown) and neutral (blue) wires. Ensure the measured resistance is within the Reference Resistance Band shown on Page 18 for the demister being tested.
Record the readings on the control card on Page 16 in line with the installation procedure.

NOTE: Due to the high resistance of the demister, it may not be possible to get a continuity reading from the demister and as such, continuity testers are not recommended.

When checking resistance, make sure your hands do not touch the meter’s probes as the measurement will include your internal body resistance and render the measurement inaccurate. If you do not get the expected results or at any time you believe there may be a problem, please contact Warmup’s Technical Team for guidance.
