4.2.3 INSTALLATION USING 4” ANSI 150 FLANGE INLET ADAPTER (SIDE A OPTION F)
When Side A option F is specified, the 4” ANSI 150 Flange Inlet Adapter is pre-installed on side A of the Booster. Eight 5/8-11 x 3” bolts,
thick washers, and nuts are supplied. One of the nuts and an O-ring seal are pre-installed between the Inlet Adapter and Booster body.
To install the Booster on a 4” ANSI 150 flange, refer to Figure 4.2.3 and the instructions below.
1. Install a ring gasket between the Booster and the mating flange.
2. Slide (7) 5/8-11 nuts into the notches on the outside of the Flange Adapter.
Washers are not necessary under these nuts. The close fit achieved by the
notches and hole diameters results in sufficient load bearing area without
washers.
3. Slide thick washers over 5/8-11 x 3” bolts. Slide (8) bolts through flanges
and tighten into nuts until snug against mating flange. To prevent damage,
verify that no bolt ends are close to contacting the Booster body. If they are
close, then stack additional thick washers under the bolt heads or substitute
studs with nuts. Stainless steel hardware is recommended.
4. Tighten (8) bolts or studs to 76-80 ft-lb (100-110 N-m) torque in the
alternating sequence shown in Figure 4.2.3. Tighten at graduated intervals
of 30%, then 60%, and finally 100% of the specified torque.
4.2.4 INSTALLATION USING 3 ANSI 150 FLANGE INLET ADAPTER (SIDE A OPTION G)
When Side A option G is specified, the 3” ANSI 150 Flange Inlet Adapter is pre-installed on side A of the Booster. Four 5/8-11 x 3” bolts
and thick washers are supplied. One of the bolts and an O-ring seal are pre-installed between the Inlet Adapter and Booster body. To
install the Booster on a 3” ANSI 150 flange, refer to Figure 4.2.4 and the instructions below.
1. Install a ring gasket between the Booster and the mating flange.
2. Slide thick washers over 5/8-11 x 3” bolts. Slide (4) bolts through flanges
and tighten until snug against mating flange. To prevent damage, verify that
no bolt ends are close to contacting the Booster body. If they are close, then
stack additional thick washers under the bolt heads or substitute studs with
nuts. Stainless steel hardware is recommended.
3. Tighten (4) bolts or studs to 76-80 ft-lb (100-110 N-m) torque in the
alternating sequence shown in Figure 4.2.4. Since only 4 bolts are required,
either the 1-2-3-4 sequence or the 5-6-7-8 sequence may be used
depending on desired orientation. Tighten at graduated intervals of 30%,
then 60%, and finally 100% of the specified torque.
NOTICE
If flange isolation washers are desired for the ANSI 150 flange joint, It is recommended to install
them under the bolt heads or nuts on the mating flange (standpipe or hydrant) rather than within the
notches on the Booster Inlet Adapter. It is not necessary to install isolation washers on both
flanges.
