Hotwire In Screed Installation Manual

Please read this instruction manual. It includes important information that will assist you and save you time and money such as,

To calculate the wire spacing start with the M2 of the area to be heated.
Multiply this by 1000. Then divide this answer by the length of the element. The answer will be the space at which the element should be laid.

Step 1 Read This Manual

• Please read this manual. It includes everything you need to know to successfully install Hotwire.
• Incorrect installation of Hotwire may lead to any warranty claim being denied.
• In some States and Territories of Australia the installation of Hotwire Under Tile
• Heating must be performed in its entirety by a licensed electrical contractor. Whist in others a licensed contractor is only required for the connections to the thermostat. Please check with your local electrical authority or Electrical Contractor to verify the requirements applicable to your State or Territory.

The Hotwire element cannot be cut, shortened or lengthened in any way.

Note : Water Proofing
It does not affect Hotwire whether the water proofing is installed under the screed or on top of the screed. Please check with the manufacturer of the water proofing as to their specifications.

Step 2 Pre wire or “Rough In”

Three things are required before Hotwire can be installed. Please see the diagram.

1. Power supply. You will need power capable of running the Hotwire element you are installing.
2. Flush Box. A vertically flush box will need to  be installed. This is a standard light switch /power point plate.
3. Draw Wire. You will need a draw wire through the wall cavity or chased into wall (if brick) and run through conduit.

Step 3 Floor Preparation

The floor needs to be completely clean. Sand, lumps of gyprock glue etc will affect your Hotwire installation. So make sure you clean the floor well. Sweep up all the dust, a once over with the vacuum is also a good idea if you have one handy. we also recommend you use a spray adhesive for added strength when fixing down your cable.

Step 4 Cable Spacing

This is really important to an excellent Hotwire installation, so please read this carefully.
Calculate the EXACT m2 of the area to be heated and multiply it by 1000 (this is to bring the measurement to square millimeters). Then divide that answer by the length of the element. This is printed on the side of the spool. The answer will be the cable spacing and should be between 75 and 120 mm. If your answer is outside this check your measurements again as you have made a mistake or have the wrong element. If this is the case do not proceed with the installation.

The above formula is a good guide. Replace with this measurement is C to C (centre to centre) of the cable so take off 7-8 mm from the calculation to get the exact space between each run.
It is a good idea to cut a jig to the size you need it rather than use a tape measure the whole time. A off cut of wood is fine, in the picture we used an off cut of electrical cable.

Step 5 Plan the installation

This is a step where you can come undone if you don’t plan properly.
The Hotwire element CANNOT be cut or shortened in any way. So have a look at the room and work out what is the most logical and simple way to run the cable around that room. You want to be doing as many long runs as possible.
Try and leave the longest wall to last. That way if you have a little too much or too little cable left you can make an easy adjustment by coming a bit further away or going right up close to the wall. Neither option will affect the heating of the room in any way.

Step 6 Check the element

Before installing the element it is always a good idea to ensure it has not been damaged during transit. We check every element before it leaves our warehouse but there is the pos-sibility that it may get damaged by a courier.

If you have a multimeter then you can check the cable against the following table.
If you don’t have a multimeter don’t panic we have you covered too.

In the Hotwire Box is a continuity alarm. It is a small black box with 3 cables coming off the end.

1. Remove small white sticker over “On / Off” Switch
2. Fix the Black clip to the Brown wire of the element.
3. Fix the Red clip to the Blue wire of the element.
4. Fix the Green clip to the remaining wire. 5: Switch the tester on.
5. A Red Light then shows that the tester is on and working.
6. If you have a fault the tester will start “Beeping”

If the alarm does not beep you are good to keep installing. There is also another use for the alarm so keep it handy, more about that after the element is down.

Step 7 Element Spacing

There are two main options for fixing the element in place. If the subfloor is clean and dust free the provided tape may be enough. If not fixing the element to a wire mesh is a great option. This product can be purchased from Hotwire or is available at most hardware stores.
We recommend,
Whites Cage Mesh 90cm x 10m x 25mm x 25mm Use small cable ties to hold the element in place.

Step 8 Roll out Element

You are now ready to start rolling out the element and sticking it down.
There is 3 meters of “Cold Tail” at the end of the element, you will notice a join between the cold tail and the thinner element wire. No part of the element or cold tail join can be in the wall cavity. This is dangerous and will void warranty.
Start spreading the element around the floor using the jig you cut earlier

Step 9 Half Way

You will notice a half way marker. It is little piece of tape around the element. When you see this stop and look at where you are up to. If you are not sure if you are half way through the floor check your measurements. Measure the remaining m2 and use 50% of the cable length to check if you are on target. If you are a little more or under half way you can spread the cable runs out or close them up a bit.

Step 10 More Tape

Stick any proud bits of element down. Some of the loops may have popped up a bit. You will also need to run a strip of cable right across the whole floor to ensure the cable does not get moved or damaged by other trades. It is a good idea to run right across the floor every meter.

Step 11 Install the Floor Probe

If using the Hotwire fully programmable ther-mostat you will now need to install the floor probe. If you are not sure check the small white box in the Hotwire box your product came in. The floor probe is a white cable that will be coiled in the bottom of that box.
Stick the probe to the floor. Make sure you don’t stick any tape over the end of the probe. It is also critical to ensure that the probe is exactly half way between two cable runs. I.e. If your measurement was 100 mm. Ensure the end of the probe is 50 mm from one run of element and 50 mm from another.
The Thermostat sensor should be run in a conduit so it can be easily replaced if required. Warranty claims on probes will not be accepted if not laid in a conduit.

Step 12 Pull Cables to Power Supply

Tape the ends both cables (cold tail and the floor probe) to the draw wire and gently pull the cable up the wall cavity or through the conduit to the position of the power supply.

No part of the element can be run inside the wall. The entire cold tail join must be buried under the floor.

Step 13 Connect Continuity Alarm

Connect the continuity alarm again. This will ensure you have not damaged the cable during installation. It will also monitor the cable while you are laying of the screed.

1. Remove small white sticker over “On / Off” Switch (if you haven’t already)
2. Fix the Black clip to the Brown wire of the] element.
3. Fix the Red clip to the Blue wire of the element.
4. Fix the green clip to the remaining wire. 5: Switch the tester on.
5. A Red Light then shows that the tester is on and working.
6. If you have a fault the tester will start
7. “Beeping” If there is no “Beep” you can continue with the installation
8. If the beep sounds at any time, before or during installation STOP IMMEDIATELY as this means that damage has occurred to the element and you will need to repair it before continuing.
9. Once you have finished the installation and before you start tiling reconnect the tester as above & turn on.
10. Keep the tester on until your tiling is complete.
11. If the tester light turns off you will need to replace the batteries.

It is a good idea to tape the alarm up with the tails so that it is not in your way while you finish the installation.

Step 14 Take a picture

Take a picture of the element layout. If there is ever a problem it will be handy to know how the element has been installed across the floor.

Step 15 Finished

Admire your work. You have just installed Hotwire.

Connecting systems over 20 m2 or 3kw

• Hotwire Thermostats are rated from 16 – 25 amps. Simply follow the instructions in the box with the thermostat to connect the heating elements and the floor sensing probe.
• If you have a system that is over 3kw you may need to install a relay in the switch-board.
• Please refer to the back of the Thermostat to confirm the capacity of the Thermostat as different models have different ratings.
• We suggest installing a 30 amp relay in the switch board. Please consult your Electrician to ensure you have the right preliminary electrical work completed.

Step 16 Notice to Tilers

Inside this manual is a yellow flier pointing out to tilers that Hotwire has been installed. Stick it to the wall in a prominent place. The flier also has a place to write your name and number for them to call with any questions.
