cluding, but not limited to, painting, plat-
ing, coating or modification, may render
the sprinkler inoperative and will auto-
matically nullify the approval and any

Flush sprinklers are provided with a
plastic protective shell which should
remain in place over the sprinkler
body during installation, testing, and
any time the sprinkler is handled or
shipped. The plastic protective shell
must be removed prior to placing the
system in service. See paragraph
"F" below. Prior to installation, sprin-
klers must be stored in a cool, dry
place in their original shipping con-
tainer. Never install sprinklers that
have beendropped, damaged inany
way, or have been exposed to tem-
peratures in excess of maximum am-
bient temperature allowed. Such
sprinklers should be destroyed im-
mediately.

rosive environments.
D. Use care when locating sprinklers
near fixtures that can generate heat.
Do not install sprinklers where they
will be exposed to temperatures that
exceed the maximum recommended
ambient temperature for the tem-
perature rating used.

rizonSprinklers. With the sprinkler
in the plastic protective shell,
place the unit into the wrench.
