Warmup WMD1 Instruction sheet

The Warmup® Mirror Demister is designed to warm bathroom
mirrors, leaving them clear and free of condensation.
Four sizes of heaters are available - two rectangular versions
(450mm X 400mm and 600mm X 1100mm), a circular (600mm
diameter) and a squarish (290mm X 290mm); all 220-240 Volts.
The heaters are self adhesive, have an IP rating of 57 and are
SEMKO certied.
The mirror used in the application must be suitable for purpose
and the instructions provided by the mirror supplier must be
adhered to.
If at anytime the heater is damaged, please contact the Warmup
Technical Helpline on 0845 345 2288.
Simple Installation:
• Lay the mirror face down on a protective surface.
• Make sure the back of the mirror is clean and free from
grease and residues.
• Mark the back of the mirror where the heater is to be
positioned. The heater should be at least 10 mm from
the edges of the mirror.
• Peel back the protective release paper from one
corner of the mirror heater. Position this corner in the
required corner of the marked area and slowly peel
back the release paper whilst applying gentle pressure
to remove air bubbles.
• The Warmup® Mirror Demister must be connected to
a loghting circuit or to an electrical circuit through
a separate 5 amp switch. The installation must be in

NOTE: When testing the resistance of the mirror demister allow a ±10% tolerance
for pads above 25w and +20% for pads below 25w.

Installation Guidelines
It is important that heaters are checked for damage before installation to ensure that the
metallic lament has not been creased and that the protective lm has not been pierced.
The size must also be checked to ensure that it will t on the mirror with a minimum
10mm gap between the lm edge and the mirror edge.
The demister must NOT be visible after installation.
The mirror to be used in the application must be suitable for the purpose. The mirror
must be completely at and free of stress and crack lines. NO accessories or other mate-
rials should be adhered or xed to mirror surface as this can create uneven temperatures
and stress upon the mirror.
The Warmup® demister must be mounted directly on to the reverse side of the mirror OR
onto a surface which is in direct contact with the mirror. The demister is self -adhesive,
NO other adhesives should be used.
The mirror must be installed on to a wall which is sound, has a at and level surface,
which is free of moisture. The wall must also be capable of bearing the weight of the
mirror. The mirror must be xed completely at to the wall to prevent stress to the mirror
and in accordance with the manufacturer’s instructions, using suitable xings. Mechani-
cal xings must NOT pierce or touch the demister OR create undue stress on the mirror or
demister due to over tightening. If the demister is to be adhered to the wall the complete
surface of the mirror back and demister must be coated with the adhesive.
ALL the installed components of the Warmup® demister including the wiring must be
protected and covered so as to be inaccessible after installation, in compliance with na-
tional safety standards.
The Warmup® demister comes with a one meter power supply cable. This cable can be
extended if required using suitable connectors and a correctly rated cable.
Fitting Instructions
IMPORTANT: e lm should be applied slowly in a constant motion as the adhesive
protective cover is removed. e protective cover should NEVER be completely removed
before applying the heater to the mirror. e heater should not be creased OR folded at any
time. Ensure no air bubbles are trapped under the lm surface.
1. Mark the location of the demister on the back of the mirror.
2. Peel the adhesive protective cover away from one corner and place at the corner of the
area to be covered.
3. Continue to slowly peel the adhesive protective cover o the lm surface, applying
rm, even pressure to adhere the lm to the surface as the adhesive protective cover is
removed.
(ensure no air bubbles are trapped at any time)
4. Once the heater is adhered to the mirror surface, locate the connector block adhered
to the mirror and measure its position relative to the mirror edges.
5. Cut a recess in the wall where the measured location of the demister power cable con-
nector will be sited, so as to allow the mirror to be adhered ush against the fall surface.
6. Feed or recess power cables to point of connection as required.
7. Ax mirror to wall using suitable xings / adhesive as per the mirror manufacturer’s
guidelines, ensuring that no cables or connector are trapped behind the mirror which
cause the mirror to be stressed or sit unevenly on the wall.
Final connections should be made by a Part P certied electrician.
Electrical Considerations
As with all electrical projects governed by Part P regulations, all mains electrical connec-
tions must be undertaken by a certied electrician. All work must be carried out in accor-
dance with the IEE wiring regulations to BS7671 or national regulations.
The Warmup® mirror demister must be connected to a lighting circuit, with a maximum 5
amp fuse of circuit breaker in the distribution board/consumer unit.
The heater can either be connected directly to a switched light circuit, which will turn on
the heater when the light is switched on OR via a separate switch connected to the main
lighting circuit.
If more than one demister is to be installed, ensure that they DO NOT overlap and that the
edges are at least 5mm apart.
The wiring MUST be 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 lighting cir-
cuit.
Any metal parts which are accessible and are in contact with the mirror must be earthed
/ grounded in compliance with BS7671 or national regulations.
