A. 8298F RF Deck Mount Adapter
Attach the 8298F RF flange to a 3” 150# ANSI flat faced steel companion flange on the
water supply pipe (P/N #81315001). Seal the flange joint with a full-face gasket, or a
suitable flange sealant. Fasten the flanges with four 5/8-11 UNC 2½” long grade 5 steel
or stainless steel bolts and compatible nuts. Apply Loctite
® #242 Thread Retainer to the
bolt threads, then thread all nuts on hand tight, and torque them to 60-70 ft-lbs in a
crisscross pattern in 20 ft-lb increments.
Caution:
When installing 8298F RF adapter on a companion flange it is
critical that the bolts be tightened uniformly to prevent cocking of the base relative to the
flange or valve. If the base becomes cocked, (see Figure 11) the 8298F RF cast flange
will fracture and fail when the bolts on the "high" side are tightened. Do not mount the
8298F RF on a raised face companion flange. A flat-faced companion flange kit is
available from Elkhart Brass (P/N 81315001).

Improper Flange Installation
The 8298F RF deck mount comes with either a full (P/N 08298111) or partial (P/N
08298131) ring gear. The full ring gear allows the Stinger RF to move 360 degrees. The
partial ring gear will allow the Stinger RF to move 270 degrees and is recommended for
use with top mount pump control panel where the operator could be endangered by the
stream. In order to achieve the direction of flow shown in Figure 12a, the 8298F RF with
the partial gear ring will need to be positioned as shown Figure 12b before mounting.
Warning:
To prevent accidental aiming of the nozzle stream towards the
pump operator, the 270 degrees ring gear 8298 RF deck mount (P/N 08298131) should be
used on apparatus with top control panels. The ring gear teeth should be positioned as
shown in Figure 12.
