Your Warmup® Underlaminate Foil Heater has been designed so that installation is quick and straight forward, but with all electrical systems, certain procedures must be strictly followed.

Please check the sizing guide at the back of this manual to ensure that y

ou ha

ve the correct heater(s) for the area you wish to heat.

Getting Started

Before installing your new Warmup®underlaminate foil heating mats, be sure you have the following additional parts:

Electrical junction box – used as the connecting junction for the electrical supply cables of the heating mats.

Control thermostat – allows you to control the temperature of the room.

Residual Current Device - Consult your electrician regarding the applicable RCD.

Hard insulation materials – used as heat insulator under the foil heating mats in installations with

concrete subfloors to provide more efficient heating. The material comes in plates, usually made from foamed Polyurethane or Polystyrene and should have Compressive strength of more than 28PSI (2Kg/cm

). An example of this is the Warmup®Insulation Board.

Please read carefully before installing your Warmup®underlaminate foil heating mats.

DON’T leave insulating materials such as bean bags; linen or towels on the floor

surface. The maximum thermal resistance recommended between the heater and the room is 0.15 m2K/W (1.5 TOG).

DON’T overlap heating mats. DON’T fold or wrinkle Warmup®Underlaminate foil heating mats. DON’T place heavy/sharp tools (or any other potentially damaging object)

on top of the heating mats.

DON’T walk unnecessarily on the foil heating mats. DON’T install electrical cables or pipes under the floor with the foil heating mats. DON’T use cellulose insulation. DON’T install mats when the room temperature is below -5ºC. DON’T install foil heating mats anywhere except inside buildings. DON’T install foil mats under walls or partitions,or in areas under heavy cabinets,

closets, or fixtures (toilets, sinks, tubs, etc.).

DON’T install foil mats within 30mm of any heat conductive building part, such as

cold water pipes.

DON’T install foil mats within 10mm of one another, 50mm of any wall, or

150mm of a fireplace or hot water pipe.

DON’T connect any other electrical appliance on the same electric fused

spur or RCD/SPUR unit of the heating system

Important!

ALWAYS ensure all earth leads are connected to the earth ring. ALWAYS ensure that the electric circuit that supplies electricity to the Warmup

Underlaminate heating system is equipped with a 30mA residual current device (RCD).

ALWAYS connect all cold wire leads from the Warmup®Underlaminate foil 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 Part P qualified electrician).

ALWAYS provide each room with an Warmup®Underlaminate foil heating system with

its own electrical junction box and control thermostat. Each Warmup®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. (To calculate the amount of Amps in the room see tables in page 16).

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 0.57ft2*h*°F/Btu (0.1m2*°C/W or 1 Tog), please read the insulation instructions on page 6 and act accordingly.

ALWAYS ensure that no sharp edges (e.g. metal-edged laminate locking systems)

come in contact with the foil heating.

ALWAYS fit the floor sensor and ensure that the thermostat is set for the correct

heater type and floor finish.

ALWAYS:

Note: Timber products often have a limitation on the maximum temperature allowed for floor heating- This is usual

ly ar

ound 27

ºC. Check with your flooring supplier what the limitations are for your preferred floor

finish.

As with all electrical projects which are subject to Part P Building Regulations, all electrical work should be carried out by a certified/qualified electrician.

All work must conform to BS 7671:2008 and the current IEE Wiring Regulations.

Before installing, draw an installation plan showing the placement of the mats, floor sensor, and junction box or boxes.

The Warmup

underlaminate foil heating mats should cover at least 80% of the floor area of your room to be used as a primary heat source*. Warmup’s foil heating mats are available in several convenient sizes. Choose the combination of heating mats that best enables you to cover the recommended 80% of your room. Plan to use the larger foil heating mats as much as possible and to use smaller mats only as gap fillers.

Note: The mats are supplied with 3 metres of electrical cold leads.If this is not enough, ask your electrician to extend the electrical supply cables.

*Depending on insulation, air-flow & overall heat-loss within the room, additional heating may be required.

1 Clean all debris from the floor base. 2 Insert Warmup® Insulation Board 3 Clean all debris from the surface of the grout or insulating material. 4 Roll out heating mats on top of the insulating material. It is recommended to leave a gap of about

50mm from the wall to the heating mats, and a gap of about 10mm between each mat. Ensure that each heating mat is completely flat. Make sure that the cold leads of the mats are on the side of the mat that is closest to the location of the electrical junction box (See step 3 – Making the Electrical Connection).

Step 2: Laying Out Your Heating Mats

Step 1: Planning Your Installation

NOTE:

When laying two or more heaters, ensure the cold tails reach the thermostat.

Step 2: Laying Out Your Heating Mats

Since the joint is slightly thicker than the rest of the mat, create a slight groove in the insulation board under the joint to ensure that the heating mat lays flat. Create a groove for the cold leads at the point at which they cross.

8 Mark each pair of cold leads coming from the same

mat with a number. Place a small sticker with the number of each pair of leads close to the end of the lead.

Note: All electrical connections must be performed by a fully qualified and Part P certified electrician.

Important! Tightly screw all connections to ensure good electrical contacts.

Install the electrical junction box or boxes above floor level according to local safety and building regulations and codes. Place the following label (attached to back cover) on the electrical junction box or boxes indicating that an underfloor heating system is installed in the room.

2 Install the control thermostat as far as possible from

any heat sources or heat sinks such as fireplaces, dir

ect sunlight

, windo

, doors, or anything that could possibly affect proper temperature readings. The sugge

sted placement is 1.6m above floor level.

Step 3: Making the Electrical Connections

Page 10

Step 3: Making the Electrical Connections

Install an electric conduit to the junction box and thermostat as in the following diagram.

4 Connect the floor temperature safety sensor to the

thermostat through a conduit, and install between two heating wire runs on the mat, at least 500mm from the wall.

Note: Make sure that the sensor is placed between two runs of wire, at the opposite end from the heating wire loop.

The probe wire must not touch or be crossed by the heating element.

Measure the resistance of the heating system and record the value. Verify that the values you measure are in line with the resistance value that is printed on the specific ma

t namepla

Page 11

Step 3: Making the Electrical Connections

All earth connections from the heaters must be connected to the earth from the power supply of the house.

7 In parallel, feed each mat to the electrical junction box. Make sure that you can see

the sticker with the numbers of the leads. If necessary, shorten the leads, but make sure the sticker with the leads' numbers are affixed to the shortened lead.

8 Expose the conductor in each lead.

9 Connect all leads of the same colour.

10 Insert each coloured lead to one connector in the junction box.

11 Connect the same colour cold lead between the thermostat and the connector

in the junction box.

WARNING:

This product MUST be used with a dedicated 30MA RCD (residual current device).

The RCD should be tested regularly in accordance with the manufacturer's guidelines.
