B-3) Storage:
This unit has been packaged and protected for shipping and
indoor storage. If it is to be stored outside for an extended
period, additional protection must be added.
Short Term - For best results, retain BAF factory assembled,
in a dry atmosphere with constant temperature for up to six
(6) months.
Long Term - Any length of time exceeding six (6) months,
but not more than twenty four (24) months. The units should
be stored in a temperature controlled area, a roofed over
walled enclosure that provides protection from the elements
(rain, snow, wind blown dust, etc..), and whose temperature
can be maintained b40 deg. F and +120 deg. F.
If extended high humidity is expected to be a problem, all
exposed parts should be inspected before storage and all
surfaces that have the paint scratched, damaged, or worn
should be recoated. All surfaces should then be sprayed
with a rust-inhibiting oil.

SECTION: C INSTALLATION
C-1) Location:
The Break Away Fitting Model BAF-6, when used in
conjunction with Barnes Pumps 6” Submersible Sewage
Pumps (Series 6SE) is recommended for operation in
a wet well, tank, or lift station. The Non-Sparking Break
Away Fitting Model BAF-E6, when used in conjunction with
Barnes Pumps 6” Explosion Proof Submersible Sewage
Pumps (Series 6XSE) is recommended for operation in a
non-hazardous or Class 1, Group D, Division 1 hazardous
location wet well, basin, or lift station.
C-2) Design Layout:
Models BAF-6 and BAF-E6 assembled with pumps listed
in Section C-1 can be installed through access covers with
sizes as listed in Table 1.

Figures 1 through 5 provide clearance dimensions, guide
pipe locations, and proposed anchor bolt locations at the
access cover opening. It is recommended that the guide
rail cap be installed with 3/8 inch stainless steel anchors.
Figures 1 and 2 provide the required anchor bolt locations
for the stationary elbow to be installed with four anchor
bolts set in a metal sleeve and accurately set into concrete.
Hook bolts can be used, however, they are more diffi cult to
locate in concrete. Use required shims under the stationary
elbow base to level the horizontal fl ange and then grout
under the base as required. A 30 day concrete cure is
required before a full load can be applied to the anchor
bolts. Design the anchor bolts for 1.6 kip uplift per bolt.
The 2” schedule 40 guide rail pipes must be plumbed after
mounting on stationary base elbow plugs. Pipe material
may be galvanized steel or stainless steel (optional from
manufacturer or supplied by customer).
C-3) Intermediate Support Assembly:
Whenever the guide pipe lengths exceed 13 feet, an
optional intermediate guide rail support bracket should be
used (see Figure 6). The intermediate guide rail support
brackets may be supported from the vertical discharge
pipe.
C-4) Installing Pump Body To Break Away Fitting:
(See Figure 7) These instructions apply to all BARNES
pumps with a 125 lb. fl ange horizontal discharge on volute.
All parts for standard and non-sparking BAF’s are the same
except for moveable assembly. BAF-6 standard assemblies
use a cast iron moveable assembly and BAF-E6
non-sparking assemblies use a bronze moveable assembly.
Position one gasket (4) between the moveable assembly (1)
comprised of Moveable (1A) and O-Ring (1B) and the pump
body discharge fl ange. Attach the discharge fl ange to the
moveable assembly with 8 hex head bolts (5), 8 split lock
washers (6), and 8 hex nuts (7). Torque each bolt to
105/115 ft. lbs.
IMPORTANT ! - BOLTS MUST BE INSTALLED
WITH HEADS ON SLIDE ASSEMBLY. BOTTOM 2
