DESIGN CRITERIA
The 5.6 and 8.0 K-Factor, Model E Vertical Sidewall Sprin-
klers are intended for fire protection systems designed in
accordance with the standard installation rules recog-
nized by the applicable Listing or Approval agency (e.g.,
UL Listing is based on NFPA 13 requirements). Installa-
tion of Model E Sprinklers in recessed escutcheons will
void all sprinkler warranties, as well as possibly void the
sprinkler’s Approvals and/or Listings.
INSTALLATION
The 5.6 and 8.0 K-Factor, Model E Vertical Sidewall Sprin-
klers must be installed in accordance with the following in-
structions:
NOTES
A leak tight 1/2 inch NPT sprinkler joint should be ob-
tained with a torque of 7 to 14 ft.lbs. (9,5 to 19,0 Nm). A
maximum of 21 ft. lbs. (28,5 Nm) of torque may be used
to install sprinklers with 1/2 NPT connections. Higher lev-
els of torque may distort the sprinkler inlet with conse-
quent leakage or impairment of the sprinkler.
A leak tight 3/4 inch NPT sprinkler joint should be ob-
tained with a torque of 10 to 20 ft.lbs. (13,6 to 27,1 Nm).
A maximum of 30 ft. lbs. (40,7 Nm) of torque may be
used to install sprinklers with 3/4 NPT connections.
Higher levels of torque may distort the sprinkler inlet with
consequent leakage or impairment of the sprinkler.
1. The Model E Vertical Sidewall Sprinklers may be installed
in either the pendent or upright position, and the flow (Ref.
Figure 1 or 2) is to be out towards the intended coverage
area.
2. With pipe thread sealant applied to the pipe threads, hand
tighten the sprinkler into the sprinkler fitting.
3. Tighten the sprinkler into the sprinkler fitting using only the
Model E Sprinkler Wrench (Ref. Figure 3). With reference
to Figure 1 or 2, the Model E Sprinkler Wrench is to be
applied to the sprinkler wrench flat area.
