2 Please read carefully before installing your Underfloor heating not: Do notoverlap heating mats. Do notfold or wrinkle the heating mats. Do not place h eavy/sharp t ools (or any other potentially damaging o bject) on top of the heating mats. Do not walk unnecessarily on the heating mats. Do not install electrical cables or pipes under the floor together with the heating mats. Do not use cellulose insulation. Do not install mats when the room temperature is below 23 F (-5 C).

3 Do not install Underfloor heating mats anywhere except inside buildings. Do not install mats under walls or partitions, or in areas under heavy cabinets,closets, or fixtures (toilets, sinks, tubs, etc.). Do not install mats within 1 inch (3 cm) of any heat conductive building part ,such as cold water pipes. Do not install mats within 2 inches (5 cm) of one another, 4 inches (10 cm) ofany wall, or 6 inches (15 cm) of a fireplace or hot water pipe. Do not connect any other electrical appliance on the same electric circuit or GFCI unit of the heating system.

4 Do not install heating mats under wooden floor, if the wooden floor is thickerthan 3/4 inch (18 mm). Do notinstall heating mats under carpet, if the R-v alue of the carpet is more than ft2*h* F/Btu ( m2* C/W). Do not put acoustic material between the heating mats and the wooden floor,when installing wooden type floor, with R-value of the acoustic materialgreater than ft2*h* F/Btu ( m2* C/W). Do NotUse grout scrapers or utility knives to clean grout joints or lines as sharptools ma y damage the heating mat.

5 Clean grout lines with a wet softsponge or soft tool m p o r t a n t !2 Always ensure that the electric circuit that supplies electricity to the underfloorheating system is equipped with a 30 mA ground fault current interrupter(GFCI) or Residual Current Device (RCD). For wet areas ensure that theelectric circuit that supplies electricity to the heating system is equipped with a 5 mA ground fault current interrupter (GFCI) or Residual CurrentDevice (RCD). Our thermostats include a built-in GFCI.

6 See page 14 fora list of recommended thermostats. Always connect all cold wire leads from the heating mats in parallel inside anelectrical junction box or boxes. Alwaysensure that the total current needed for all mats connected in parallelis not more than 80% of the listed amperage capacity of the electrical junction box and its power supply line and breaker (For advice consultyour recommended installer / supplier). Always Always use insulation under the mats to reduce running costs and warm-uptime. Check with your installer to determine the R-value of the sub floorinsulation layer.

7 If there is no insulation, or if the R-value of the insulationlayer is lower than ft2*h* F/Btu ( m2* C/W or 1 Tog), please read the insulation instructions on page 5 and act accordingly. Always Clean grout lines and joints with soft sponge rather than groutscr apers or utility knives. Cleaning grout joints with sharp tools ma ydamage the :Note : If you are installing any type of glued-down floor covering, cover the mats with atleast 1/4 inch (6mm) self-leveling flooring cement.

8 Plywood sheathing can be usedinstead of self leveling flooring :All electrical connections must be performed by a fully qualified : The installer must verify the conformance to all applicable codes or m p o r t a n t !provide individual heating systems in each room with its own electricaljunction box and control thermostat. Each thermostat has a maximumcapacity of 15 amps. If the amount of amps in the room is greater than15 amps, use master and slave units (see page 14), or add a contactorbetween the mats and the thermostats.

9 (To calculate the amount of ampsin the room see tables on page 15).Getting StartedGetting StartedBefore installing your new Underfloor heating mats, be sure you have the following additionalparts: Electrical junction box used as the connecting junction for the cold leads of theheating mats. Grounding net In wet surroundings, it is recommended to la y a grounding netespecially if electrical appliances are :We recommend using an AHTGN family of grounding net. Control thermostat allows you to control the temperature of the room.

10 Thecontrol thermostat must also have a two terminal manual on/off thermostats have one or two of the following sensors: Ambient air temperature safety sensor. Floor temperature safety bathrooms, use thermostat with only floor temperature thermostat with air and floor temperature sensors for all other :We recommend our digital fully programmable thermostats and master thermostats,which allo ws you maximum flexibility in creating your weekly heating page 14 for a list of recommended thermostats.
