Always
cover mats with grounding net in wet areas. Wet areas include saunas,
bathrooms, and kitchen areas within 50 cm (20 inches) of sinks or any
metallic kitchen appliance.
£
Always
ensure that the electric circuit that supplies electricity to the
AHT
heating
system is equipped with a 30 mA ground fault current interrupter (GFCI)
or residual current device (RCD).
£
Always
connect all cold wire leads from the
AHT
heating mats in parallel
inside
an electrical junction box or boxes.
£ †††
Always
ensure that the total current needed for all mats connected in parallel
is not more than 80% of the listed amperage capacity of the electrical
junction box and its power supply line and breaker (For advice consult
your recommended installer / supplier).
£
Always
provide each room with an
AHT
heating system with its own electrical
junction box and control thermostat. Each
AHT
thermostat has a
maximum capacity of 16 Amps. If the amount of Amps in the room is greater than
16 Amps, divide the amperage over several thermostats, or add a
contactor between the mats and the thermostats. (To calculate the amount
of Amps in the room see tables in page 15).
£
Always
use insulation under the mats to reduce running costs and warm-up
time. Check with your installer to determine the R value of the sub floor
insulation layer. If there is no insulation, or if the R value of the insulation
layer is lower than 0.1 m

Always
wait for thin set/grout to dry properly before operating the system. The
drying period is generally 2-14 days depending on manufacturer’s
instructions.
Always:
Note:
If you are installing soft type of floor covering (vinyl or linoleum), cover the mats
with at least 6mm (1/4 inch) self-leveling flooring cement or latex compound.
Note:
All electrical connections must be performed by a fully qualified electrician.
Note:
The installer must verify the conformance to all applicable codes or standards.
