Place ruler on glass along broken line. Deposit conductive silver composition on break with drawing pen. Slightly overlap existing heat wire on both sides [preferably 5 mm (0.20 in)] of the break.

After repair has been completed, check repaired wire for continuity.

This check should be conducted 10 minutes after silver composition is deposited.
