Basic electrical tests are required at the various stages of installation and the results should be recorded on the guarantee card provided.

Check before installation, immediately after installing and before putting the heating into operation.

Test for cable continuity and its resistance (ohms), as well as the resistance of the sensor cable.

Also, measure the insulation resistance value as required by BS7671 – the minimum reading should be 10 megohms regardless of element length.

Record the results on your guarantee card.

Consult your electrician.
