Installation
Instructions
NOTE: If using flanged
connections, be certain that
adequate
clearances
are
provided throughout for the
installation of bolts, nuts, lock
washers, and gaskets.
If total run of vertical piping
exceeds twelve (12) feet, install
a piping brace at the approximate
midpoint of the piping. Secure
brace (i.e., U-bolt with angle iron
strap and angle iron extensions) to
both piping and wall of basin.
4. Basin Cover(s)
The basin cover for the sump
and valve box can either be
poured concrete or precast.
If Hydromatic door and frame
assemblies are used, locate the
concrete openings with respect
to the discharge elbow mounting
studs as shown in the Installation
Data. If the covers are poured,
place the door and frame assembly
inside the concrete form and
position per installation data.
Anchor straps are provided on
the door frames to secure them to
the concrete. If precast covers are
used, remove anchor straps from
frame before installing into covers.
Either cast four
3
⁄
8
” anchor bolts
into the top of the precast cover or
drill holes for expansion lag screws.
Use either
3
⁄
8
” nuts or stainless
steel bolts to secure door and frame
assembly to cover. If valves are
to be inside the wet well, provide
access ways as required for the
piping and valves to access piping
shut-off valves (see Installation
Data for general dimensions of
access ways). Access ways must be
covered and secured with tamper-
proof hardware (by others).
5. Guide Rail Installation
Install the pultruded guide rail
(I-beam) by attaching the lower
end of the guide rail to the
slotted lugs on the top side of the
discharge elbow. Two
3
⁄
8
” x 2”
bolts, one rectangular washer, lock
washers, and nuts are provided
with the discharge elbow parts
package. At the top of the guide
rail, plumb and then fasten the
guide rail to the door & frame
assembly or other suitable
bracket, using the four
1
⁄
4
”
x 1 stainless steel cap screws.
If Hydromatic door and frame
assemblies are not used, obtain
suitable upper guide rail brackets
(by others) to locate and support
the rail(s). A flat surface 4” wide
is required for each rail.
6. Intermediate Guide
Rail Bracing
Sump depths of 9’6” and greater
require intermediate guide rail
bracing. The braces mount on
the vertical discharge pipes with
U-bolts which are sized according
to the discharge pipe size. The
number of guide rail braces
required are as follows:
Sump Depths
9’6” to 18’0” 1 guide rail brace
required
18’6” to 27’0” 2 guide rail
braces required
27’6” to 30’0” 3 guide rail
braces required
On depths requiring more than
one brace, space the braces
equally on the pipe and tighten
U-bolts. Match drill two
5
⁄
16
” holes
through the guide rail flange and
attach with two
1
⁄
4
” x 1” stainless
steel bolts, nuts, and lock washers
provided with braces. Install with
bolt heads against the bracket.
7. Exterior Piping
Install the inlet hub(s) in side
of basin and install inlet piping
in hub and grout, or install inlet
pipe(s) directly into basin and
grout. Install drain pipe from
valve box (if required) to basin.
Slope pipe to give proper drainage
to basin. Install vent piping in side
of basin (if required). Extend
piping to a proper elevation above
grade (as required by plans and
specifications and/or local codes).
All piping furnished by others.
See Installation Data for typical
piping arrangement.
8. Pump and Sealing Flanges
Assemble the sealing flange (with
arms) to the pump discharge
flange using a gasket between the
two. Screw nuts with lock washers
on the bottom six studs. Slide
the guide rail connector through
the sealing flange ears and below
the top two studs protruding
through the back side of the pump
flange. Place the retainer clips on
the studs followed by lock washers
and nuts and follow illustration.
9. Pump Installation
Check all piping braces and
supports for proper installation
and tightness. Attach the lifting
chain assembly or cable to the
lifting eye(s) on the top of
the pump with the shackle(s)
provided. Lower the pump into
the basin with the guide rail
connector engaged over the
pultruded guide rail (I-beam).
Ensure that the chain or cable
does not interfere with the cord
cap assembly. Attach the upper
end of lifting assembly to the
hook provided on the inside of the
Hydromatic door and frame. The
heavy rubber sealing diaphragm
on the pump discharge should not
touch the discharge elbow flange
when the pump is being installed
or removed, or is installed but not
