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.
