REPAIR EQUIPMENT
●
Conductive silver composition (DuPont No. 4817 or equivalent)
●
Ruler 30 cm (11.8 in) long
●
Drawing pen
●
Heat gun
●
Alcohol
●
Cloth
REPAIRING PROCEDURE
1.
Wipe broken heat wire and its surrounding area clean with a
cloth dampened in alcohol.
2.
Apply a small amount of conductive silver composition to tip of
drawing pen.
Shake silver composition container before use.
3.
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.
4.
After repair has been completed, check repaired wire for conti-
nuity. This check should be conducted 10 minutes after silver
composition is deposited.
Do not touch repaired area while test is being conducted.

5.
Apply a constant stream of hot air directly to the repaired area
for approximately 20 minutes with a heat gun. A minimum dis-
tance of 3 cm (1.2 in) should be kept between repaired area and
hot air outlet.
If a heat gun is not available, let the repaired area dry for 24
hours.
