3. POINTS OF ATTENTION:
The cable is insulated and watertight and can be installed on Foil finished insulation(Kingspan or Celotex) or existing concrete bases. The construction of the cable also allowsinstallation in wet spaces. The heating cable may never be installed under fixed objectslike wall units, kitchen units, baths, or showers and must be able to give off its warmthunimpeded.
The power supply must be disconnected during installation. All installations must be wiredthrough a suitably rated MCB or RCCD when applicable. All installations in wet areasmust be wired through a dedicated RCCD in line with the thermostat. All connections mustbe made by an approved Electrician in accordance with current IEE regulations.The electrical heating cable is patented worldwide and fully conforms to the EuropeanIEC 800 standards.
The cables capacity is 17W per meter at 230V. The invisible transition of the resistancecable (heating section of the cable) to the power cable (cold connection part of thecable) is indicated by the word "SPLICE" between two arrows. The 2 meter power cablemarked with stars: ******, may be extended.
THE HEATING CABLE CANNOT BE SHORTENED!!!! THE END SEAL CANNOT BE BROKEN!
This Klima Cable is a twin conductor (built in return cable) and has an extra aluminiumearth cladding to neutralise magnetic fields.
If multiple cables are installed in a space, they must be wired in parallel and a suitablyrated junction box may be incorporated so that only one power cable runs to the thermo-stat. Maximum capacity of the thermostat is 16 Amperes. If fitting more than one cableset and the combined area length exceeds 3400 watts, a suitably rated Contactor willhave to be fitted. The thermostat may only be installed by a qualified electrician.
The Klima Cable can be used under various floor finishes - Tile, Marble, Slate, Wood,Laminate, Vinyl and Carpet. (Tog rate of carpet and underlay should not exceed 2.5).If using underneath a wooden floor or carpet please contact your flooring supplier.

4. GUARANTEE:
The electro technical part of the floor heating is guaranteed for 10 years. The thermostatis guaranteed for 2 years. The guarantee does not apply to damage caused by externalfactors and/or incorrect installation.
5. NECESSARY MATERIALS:
- Standard junction box (min 35mm deep, preferably 50mm) for the thermostat.- Mounting material: Tie wraps, Spacerstrips or smooth Weld Mesh.- Electrical conduit for the connecting cable for the thermostat.- A multimeter to test the mat after each installation activity.
6. PREPARATIONS:
- Check that the cable length/wattage is correct for the area of free floor surface that must be heated.
- Check the available electrical connection and mains voltage in the space for installation.- Test the cable with a multimeter and check if the resistance (Ohms) coincide with the test
data in Section 2. Measure both between the resistance wires themselves and between the resistance wire and the earth cladding, whereby the latter should give a reading of0 and not swing.
- 1 or 2 grooves must be cut/ground in the wall for electrical conduits, 1 for the power cable and 1 for the floor sensor. Do not run the power cable and sensor cable through the same pipe.TAKE CARE: DO NOT PLACE THE SENSOR IN THE VICINITY OF A (HIDDEN) RADIATOR OR WATER PIPE!
- Ensure that the base floor is clean and level.- Always apply insulation to the base floor if possible. Uninsulated floors will have
downward heatloss.- Place expansion strips around the perimeter of the area (for coping with the contraction
and expansion of the floor).

7. CALCULATIONS FOR HEAT REQUIREMENTS:
150 + watts/m² for prime heating of normal rooms cable spacing 100 mm
100/125 Watt sq. m for comfort heating of normal rooms cable spacing 125/150 mm
Example: for a Kitchen of 20 sq. m floor surface multiply the total floor surface with theabove mentioned capacities (20 x 150 Watt = 3000 Watt) Choose 2 x 1700 watt.Cable can be sized (or checked) by measuring the linear length i.e. Heat required 150watts/m².
Room size 4mx2.5m = 10m² Cable spacing = 100mm Therefore 4mx25 = 100 linear mts.Use 1700 Watt set (100 linear mts).
If there is any excess cable left after installation, you can space a few runs at 50mm atthe window & door areas of the room to lose it in the floor.Please contact the KLIMA Technical Department (0870 411 1115) if you require assis-tance on the spacing of the cable.
NEVER SHORTERN THE KLIMA CABLE!
8. RESISTANCE READINGS:
Please make a note of your resistance readings in the table below. This forms your guar-antee. Readings to be taken with an ordinary Multimeter. Please also make note of theresistance readings on your inspection card.
* Should always read open circuit. If not: STOP immediately and call the technical helpline.

9. FITTING THE CABLE TO THE FLOOR:
Feed the cable end (marked with *******) through the electrical pipe to the back box forthe thermostat. The word "splice" must stay visible. Splice must be covered by screed.Fix the spacer strips at 500 - 600 mm centres with masonary or Hilti nails. Attach thecable in a zigzag fashion with a distance between the cable as required.If reinforcing is used (*Smooth Weld mesh at 100mm square) plastic tie wraps can beused for attaching the cable directly to the reinforcing.
Extend the 2nd electrical pipe to about 50 cm from the wall and have it end in the mid-dle of a cable loop. Pull the sensor cable to the back box and ensure that the sensor is inthe conduit. Ensure the cap is placed on the end of the conduit so that replacing the sen-sor is always possible.Please contact the KLIMA Technical Department (0870 411 1115) if you require assis-tance on the spacing of the cable.
*Refer to centre pages.
10. APPLYING THE MORTAR:
10 A: APPLIED DIRECTLY TO A CONCRETE SUBFLOOR:
1. Lay the spacer strips at 500 -600mm centres. Attach the cable at the desired/specified spacing.
2. Ensure a good bond by brushing the subfloor with cement powder or PVC glue.3. Then apply a layer of sand/cement screed (5/6:1) of 3.5 to 5.0 cm. Allow it to cure
before the tiles can be laid or other types of floor coverings applied.4. This method of application is also suitable for applying pourable liquid screeds in
thicknesses of between 3 and at most 6 cm.5. Protect the cables when bringing in the cement or grout by using duckboards. Never
use wheelbarrows with unprotected footrests.NB: For large spaces it is necessary to create or observe expansion joints in multiples ofapprox. 40/50 m2. The cables may not cross the expansion joints to avoid damaging the cables.
6. Remember to take the resistance readings throughout this installation process.
10 B: APPLIED DIRECTLY ON TOP OF INSULATION:
When laying the KLIMA CABLE onto the insulation the KLIMA CABLE must be laid andsecured onto a steel mesh. Do not install the cable directly onto the insulation. The cableis laid on to a smooth reinforcing mesh (approximately 100mm square), and secured withtie wraps. When using insulation, the top surface of the insulation must be aluminium cov-ered and coated appropriately to resist reaction with screed. Kingspan and Celotex man-ufacture insulation boards for the sole purpose of underfloor heating. The cable must notcome into contact with the insulation. Contact the insulation manufacturer for compatibilitywith cable floor heating systems and fitting instructions.The minimum depth of screed is 75mm. It is very important that the bedding is appliedfree of air bubbles. Air bubbles form insulating, non-conductive areas where the cablecannot release its heat and a danger of overheating arises which can cause damage tothe cable. To avoid this first of all wetter screed must initially be used to enclose thecable in the screed. Following this drier cement can be used for levelling the final bed-ding. In this case a pourable liquid screed is also a good option. Protect the cables whenbringing in the cement or grout by using duckboards. Never use wheelbarrows with unpro-tected footrests. Remember to take the resistance readings throughout this installationprocess and mark opposite.
10 C: ON DOVETAILED SHEETING:
Always allow for expansion. Dovetailed subfloors offer very poor insulation. It is recom-mended the dovetailed sheeting is insulated from below. Then fill in the grooves with mor-tar before installing the cables. Then install as indicated in Chapter 10A. In the latter casepourable liquid screed method can also be applied. Protect the cables when bringing inthe cement or grout by using duckboards. Never use wheelbarrows with unprotectedfootrests.
11. USING THE SYSTEM FOR THE FIRST TIME:
Depending on the drying time specified for the cement or grout, however not sooner than30 days after installation due to the natural expulsion of moisture from the floor. Turningon the system sooner can damage the floor.
