spected and the wax coating re-
touched (repaired) whenever the coat-
ing has been damaged and bare metal
is exposed. The wax coating on the
wrench flats can be retouched by gen-
tly applying a heated 1/8 inch diameter
steel rod to the areas of wax that have
been damaged, to smooth it back over
areas where bare metal is exposed.
NOTES
Only retouching of the wax coating ap-
plied to the wrench flats and frame
arms is permitted, and the retouching
is to be performed only at the time of
the initial sprinkler installation.
The steel rod should be heated only to
the point at which it can begin to melt
the wax, and appropriate precautions
need to be taken, when handling the
heated rod, in order to prevent the
installer from being burned.
If attempts to retouch the wax coating
with complete coverage are unsuc-
cessful, additional wax can be ordered
in the form of a wax stick (the end of
which is color coded). Only the correct
color coded wax is to be used, and
retouching of wrench flats and frame
arms is only permitted at the time of
initial sprinkler installation. With the
steel rod heated as previously de-
scribed, touch the rod to the area re-
quiring additional wax with the rod an-
gled downward, and then touch the
wax stick to the rod approximately
one-half inch away from the area re-
quiring retouching. The wax will melt
and run down onto the sprinkler.
