Xylem 19 001 251 R3 Floboy VFD Pumping System - Manual (Page 13)

9
Concrete slabs should be at least 6" thick and be
constructed in a monolithic pour from 3000 psi
concrete and #5 rebar. The slab should be sized
with a minimum of 6" clearance between the edge
of the slab and the edge of the pump station.
Please note that it is the customer's
responsibility to meet all local code and
seismic requirements.
WARNING: Falling Objects Hazard -
Heavy Load, May Drop If Not Lifted
Properly.
Do not lift the entire unit by component eyebolts.
Eyebolts on components are used for factory
assembly only and are not intended to lift the
complete package.
Failure to follow these instructions could result in
serious personal injury or death, or property
damage.
FOUNDATION
With proper installation and a suitable foundation,
this unit is built to supply years of service.
Establish a base of concrete weighing a minimum
of 2-1/2 times the weight of the unit. (Check the
shipping tickets or the pumping system drawing for
unit weight.) Tie the concrete pad in with the
finished floor. Use the appropriate anchor bolts to
secure the pumping system to the foundation.
Pump packages with electrical conduit below
surface may require corrosion protection approved
for this condition.
WARNING: Electrical Shock Hazard
Electrical conduit installed below the surface may
require a corrosion resistant protective coating to
prevent conduit corrosion and electrical shock.
Failure to follow these instructions could result in
serious personal injury or death, or property
damage.
Place the unit on its concrete foundation,
supporting it with steel wedges or shims. These
wedges or shims should be put on both sides of
each anchor-bolt and midway between the bolts,
to provide a means of leveling the base.
After the pumping system has been leveled, install
the correct number of anchor bolts and tighten to
secure the system.

ANCHORING THE STATION
It is always advisable to anchor the station to the
concrete slab or support structure in two or more
locations. Four 1/2" diameter holes have been
provided in the base of the pump station skid for
this purpose. Concrete anchors, such as 3/8" x 4"
Redheads, work well on most concrete structures.
Anchor all four holes. Please note that it's the
customer responsibility to meet any seismic
requirements if applicable.

slab.
SUCTION PIPING
Suction piping is perhaps the most sensitive and
demanding element of the pump station
installation. Proper suction piping can make the
difference between the pump station operating
properly or not working at all. The following rules
should be observed in the installation of every
suction assembly:
