MAGNUM Mat

3. Points of attention
The MAGNUM Mat electrical floor heater
consists of a heating cable that is equally
distributed and connected to a glass fibre net
with an inter-loop distance of approximately
7cm. The MAGNUM Mat is fully earthed.
Check before hand if the heating mat is the
right size for the floor area to be heated and
that there is sufficient electrical capacity (Amps.)
available. The mat may not be positioned over
expansion joints. Each mat is tested at the
factory and has a unique inspection card. Every
mat is tested at 4000 volt.
Before installing the mat, the resistance reading
should be taken and noted down on the
inspection card in the center of this manual.
(See point 7).
The connector cable can be extended or
shortened, there must always be at least 0.5
meter of connecting wire left. The heating cable,
attached to the yellow glass fibre net, cannot
be cut. The mats cannot be laid over each other
and the heating cables may never cross each
other! The cable junction is the transition of the
resistance cable (heating section of the mat) to
the power cable (cold connection) is just within
the heating mat and is marked.
A distance from the wall of 10 to 20 cm should
generally be adhered to. The MAGNUM Mat
may never be installed under fixed objects like
wall units, kitchen units, baths, or showers and
must be able to give off its warmth unimpeded.
The MAGNUM Mat may only be incorporated
into the free floor areas. As bathrooms
consist mostly of a small free floor area the
mat can only be installed as supplementary
heating. Please contact your local supplier for
information about use as main heating.
All installations must be wired through a suitably
rated MCB or RCCD when applicable. All installations
in wet areas must be wired through a dedicated
RCCD in line with the thermostat. All connections
must be made by an approved electrician in
accordance with current local regulations.
The MAGNUM Mat is 3 to 4 mm thick and must
be incorporated in a flexible adhesive or casting
mortar suitable for floor heating. Check the
manufacturers data.
The MAGNUM Mat has 1 connecting cable 3.5
meters in length (Twin Conductor) and has an
end seal (loop) at the end of the mat. The end seal
CANNOT be broken. The connector cable can be
shortened, there must always be at least 0.5 meter
of connecting wire left. The power supply must
never be connected during installation.
If multiple mats are installed in a space, they
must be wired in parallel and a suitably rated
junction box may be incorporated so that
only one power cable runs to the thermostat.
Maximum capacity of the thermostat is 16
Amperes. If combined area exceeds 23m², a
Contactor will have to be fitted. The thermostat
may only be installed by a qualified electrician.
The sensorcable can be extended or shortened.
The sensor must be installed in the middle of a
cable loop for optimal temperature registration.
Ensure that the sensor is installed well clear (min.
50 cm) of (hidden) radiator and water pipes,
drains and electrical wiring. The sensor must
always remain IN the sensor tube. Fit cap to end
of the sensor tube. If the sensor ever needs to be
replaced it can then easily be removed.
The MAGNUM Mat is primarily designed for
installation on concrete floors. If laying on a
wooden floor, all floors must be sheeted with a
cement faced board which is compatible with
heated floor systems. Or sheet the floor with 15
mm WBP or Marine plywood, fix with screws
at 200mm centres and then skim with 2-3 mm
of flexible tile adhesive and allow to dry, then
proceed as installation for concrete base.
