1. Plan

Design the system & make a layout to ensure best distribution of the elements. Elements should be placed in open areas away from conductive materials, plumbing & fixed fittings, and having regard to the heating requirements of the room.

Proper thermal insulation is vital  - both in the floor, and in the perimeter.  Any gaps or voids will seriously undermine the effectiveness of the system.  Insulation can be achieved effectively and economically by using Kapron board where required.

 2. Install

Roll the element out on the floor and cut to length according to layout. Lay the element strips side by side following the recommended spacing. The element can be attached to the subfloor using the following alternatives:

A.  Staple element at least 1 inch from edge with staples no larger than  3/8 inch. If the staple hits a bus braid, cut the element, splice and seal properly.

B.  Tape down. Use only approved tape and apply perpendicular to the direction of  the element.

C.  Cement mortar or latex-modified mortar can be used for levelling or  when installing tile or underlay.

NOTE: Do NOT use non-approved tape or adhesive based products (premix thin-set, primer, leveler or equivalent) to adhere the element as these may react aversely with the polymer of the element.  Avoid contact between elements. Do NOT puncture the bus braids.

3. Connect

Connect extension wires to the elements according to the drawings and electrical diagram. Determine wire gauge versus load.

Route the wires flat on the floor, up or through the wall in conduits, under the baseboard or below the subfloor. Connect wires in parallel to the 24 volt EP Transformer. Use only stranded tinned copper wires and do not twist ends when connecting to the interface board in power supply.

Distribute the load evenly. The maximum load per circuit is 450 watts.

The EP Transformer must be installed in a well ventilated area and wired in accordance with the Regulations. Place the power supply in a way that it does not vibrate and give resonance in the building structure.

Connect the line voltage to two-pole on/off switch. Use stranded wires from the switch to the EPTransformer. For control options, see the EP Handbook (please contact us).

The heating elements must be measured and amps noted by a certified electrician before being covered.
 

GETTING IT RIGHT

Our installation teams are all approved, fully-trained professionals. We have the experience to ensure that every job runs smoothly and to make sure that you are 100% satisfied with your EPWarmfloor system from the start.

Installation must conform to local building codes, regulations & trade practices.

he installation must be checked by a qualified electrician in accordance with current regulations BEFORE the element & wiring is covered.

 All commercial, domestic and industrial wiring installations must be designed, constructed, inspected, tested and certificated to meet the requirements of BS 7671: 2008. )

A higher R-value is required under the heating elements as opposed to over with a ratio of 4:1.

Consult insulation manufacturer for deflection/load characteristics, and check that the product and installation procedure is approved for the application.

Any installation not done in accordance with manufacturer's instructions may invalidate the guarantee.
