stalled in ac cor dance with rec og nized
in stal la tion stan dards. De vi a tion from
the stan dards or any al ter ation to the
sprin kler af ter it leaves the fac tory in -
clud ing, but not lim ited to: paint ing, plat -

stal la tion.
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. Never in stall any glass-bulb
sprin kler if the bulb is cracked or if
there is a loss of liq uid from the bulb.
If a glass bulb lacks the ap pro pri ate
amount of fluid, it should be set aside
and re turned to Vi king (or an au tho -
rized Vi king dis trib u tor) for anal y sis
as soon as pos si ble. If the sprin kler is
not re turned to Vi king, it should be
de stroyed. Never in stall sprin klers
which have been ex posed to tem per -
a tures in ex cess of the max i mum am -
bi ent tem per a ture al lowed (these
sprin klers should be de stroyed im -

C. Cor ro sion-resistant sprin klers must
be in stalled when sub ject to cor ro -
sive at mo spheres. When in stall ing
sprin klers with a cor ro sion-resistant
coat ing, care must be taken not to
dam age the coat ing. Use only the
spe cial wrench de signed for in stall -
ing coated and re cessed Vi king ELO
sprin klers. (Any other wrench may
dam age the coat ing.)
D. 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 stal la tion,
be sure to have the ap pro pri ate sprin -
kler model and style, with the cor rect
or i fice size, tem per a ture rat ing, and
re sponse char ac ter is tics.
1. In stall es cutch eon (if used), which
is de signed to thread onto the ex -
ter nal threads of the sprin kler.
2. Ap ply a small amount of pipe-joint
com pound or tape to the ex ter nal
threads only, tak ing care not to al -
low a build-up of com pound in side
the sprin kler in let.
3. In stall the sprin kler on the pip ing
us ing the spe cial sprin kler wrench
only, tak ing care not to dam age
the sprin kler op er at ing parts. DO
NOT use the sprin kler de flec tor to
start or thread the sprin kler into a
fit ting.
E. Af ter in stal la tion, the en tire sprin kler
sys tem must be tested in ac cor dance
with the rec og nized in stal la tion stan -
d e r dards. The test is ap plied af ter the
sprin kler in stal la tion to en sure that no
dam age has oc curred to the sprin kler
dur ing ship ping and in stal la tion, and
to make sure the sprin kler has been
prop erly tight ened. If a thread leak
oc curs, nor mally the sprin kler must
be re moved, new pipe-joint com -
pound or tape ap plied, and then re in -
stalled. This is due to the fact that
when the joint seal is dam aged, the
seal ing com pound or tape is washed
out of the joint. Air test ing the sprin -
kler pip ing prior to test ing with wa ter
may be con sid ered in ar eas where
leak age dur ing test ing must be pre -
vented. Re fer to the In stal la tion
Guides and the Au thor ity Hav ing Ju -
ris dic tion.
F. Sprin klers must be pro tected from
me chan i cal dam age. Wet pipe sys -
tems must be pro vided with ad e -
quate heat. When in stall ing Model M
