B. Sprin klers must be han dled with care.
They must be stored in a cool, dry
place in their orig i nal ship ping con -
tainer. Never in stall sprin klers that
have been dropped or dam aged in
any way. (Such sprin klers should be
de stroyed im me di ately.) Wet-pipe
sys tems must be pro vided with ad e -
quate heat.
C. The sprin klers must be in stalled af ter
the pip ing is in place to pre vent me -
chan i cal dam age. Be fore in stall ing,
be sure to have the ap pro pri ate sprin -

D. With the sprinkler con tained in the
plas tic pro tec tive cap, ap ply a small
amount of pipe-joint com pound or

tak ing care not to al low a build-up of
com pound in the sprin kler or i fice.
E. With the sprin kler con tained in the

(shown in Fig ure 1) to the sprinkler
wrench flats only, while tak ing
care not to dam age the sprin kler
op er at ing parts. DO NOT use any
other type of wrench, as this could
dam age the unit. DO NOT use the

sprin kler into a fit ting. DO NOT ex -
ceed 50 ft. lbs. of torque (hand
tight, plus ap prox i mately two full
turns with the wrench) to in stall
these sprin klers. Higher lev els of
torque may dis tort the sprin kler in -

F. Use only the spe cial sprin kler wrench
and im me di ately re place any dam -

This is due to the fact that when the
