11. INSTALLING THE MAT
Step 1 - Planning the installation
Before installing, draw an installation plan showing the placement
of the mats, floor sensor, and junction box or boxes. The foil heating
mats should cover at least 80-90% of the floor area of the room to be
used as a primary heat source (depending on insulation, air-flow
and overall heat-loss within the room, additional heating may be
required). Choose the combination of heating foils that best enables
to cover the recommended 80-90% of the room. Plan to use the
larger foil heating mats as much as possible and to use smaller foils
only as gap fillers. It is important to keep an accurate record of where
the mats are installed
.
Note:
The mats are supplied with a 3 metre long electrical cold lead.
If you need longer connection leads, these may be extended consult
a qualified electrician.
Step 2 - Check and prepare the subfloor
The heating foil MUST NOT be installed in thinset cement, or in direct
contact with a cement or concrete subfloor. There must always be a
soft insulation / underlay beneath the aluminium heating foils.
Carefully inspect the subfloor and make sure it is clean, free of sharp
edges, protruding nails and any other materials that may damage
the heating foil.
Lay the insulation as per the manufacturer instructions. If you are
using the Rointe insulation board you will need to install a soft
underlay on top of the boards.
Remove the foil heating mat from the packaging and check the mats
visually for any damage.
Test using a multi-meter and verify the correct resistance against the
table on page 4. Record the readings on the control card at the back
of the manual.
Step 3 - Laying out the heating foils
Roll out the heating foil on top of the insulation material. Keep the
heating foil at least 50mm from the edges of the room.
Ensure that the heating foil is completely flat. Care should be taken
not to fold or crease the foils at any time during installation.
Position it in such a way that the power cord will be able to reach the
point where the thermostat will be connected.
If fitting more than one heating foil ensure that the foil does not
overlap, as overheating will result. Leave a gap of at least 20mm
between each foil.
Secure the foil mat to the underlay using tabs of duct tape to hold
the foil in position.
