ing ridges must be installed with their frame arms per-
pendicular to the ceiling ridges.
Failure to properly orientate the sprinkler frame arms
may result in impaired fire protection due to cold sol-
dering and/or inadequate spray coverage.
Do not attempt to compensate for insufficient adjust-
ment in an Escutcheon Plate by under- or over-tight-
ening the Sprinkler. Readjust the position of the sprin-
kler fitting to suit.
1. The sprinkler must only be installed in the pendent position
and with the deflector parallel to the mounting surface.
2. After installing the #2084 or #2085 mounting plate (or other
acceptable escutcheon, as applicable) over the sprinkler
pipe threads and with pipe thread sealant applied to the
pipe threads, hand tighten the sprinkler into the sprinkler
fitting.
3. Wrench tighten the sprinkler using only a W-Type 7 Sprin-
kler Wrench (Ref. Figure 5). The wrench recess of the
W-Type 7 is to be applied to the sprinkler wrench flats (Ref.
Figure 1).

(a) For coverage area dimensions less than or between those
indicated, it is necessary to use the minimum required flow for
the next highest coverage area for which hydraulic design
criteria are stated.
(b) Requirement is based on minimum flow in GPM from each
sprinkler. The associated residual pressures are calculated
using the nominal K-factor. Refer to Hydraulic Design Criteria
Section for details.
