Test the wall heating panel(s

)

You must test the heater before, during and after installation to ensure that the 

panels have not been damaged during the installation. 

Using a multi-meter test the resistance of each individual heating  panel.

Set the multi-meter at 200 ohms setting for larger panels and a 2k ohms setting for 

the smaller mats.  Test across the Live and Neutral. 

At 20°C between live and Neutral the heater should read

A +/- 5% Ohm reading tolerance is allowed under manufacturing guidelines. 

A insulation resistance test must also be carried out on the heating panel. Carry out 

the test across the conductors and Earth at 1000V. 

Record the ohms reading and the insulation resistance test results on the control 

card included in this instruction manual. 

If the heater fails the insulation resistance test , the ohms reading is open circuit  or 

above/below the allowed tolerance 

DO NOT TILE

 contact the technical helpline on 

0845 345 2288.

All test results must be recorded on the control card at the back of the manual. 

NOTE: DO NOT WIRE THE HEATING ELEMENT TO THE MAINS WHILE THE HEATING PANEL 

IS STILL ROLLED UP.
