grooved before the concrete sets; this provides a bonding
surface for the grout.
Foundation bolts should be set in concrete as shown in Fig.
6. An optional 4 inch [102mm] long sleeve around the bolts at
the top of the concrete will allow some flexibility in bolt
alignment to match the holes in the base plate. Allow enough
bolt length for grout, shims, lower base plate flange, nuts and
washers. The foundation should be allowed to cure for
several days before the base plate is shimmed and grouted.
In installations where lower sound and vibration levels are
particularly important, we recommend a foundation with a
mass of at least 5 times that of the complete pump unit.

WARNING
Lifting devices must be sufficiently strong and
must only be used by authorized persons.
Eyebolts or lifting lugs, if provided, are only for
lifting the components to which they are
attached. Do not stand underneath suspended
loads. A failure in the lifting device or rigging
can result in serious personal injury or death,
or property damage.
NOTICE
This procedure assumes that a concrete
foundation has been prepared with anchor or
hold down bolts extending up ready to receive
the pump unit. It must be understood that the
pump and driver have been mounted and rough
aligned at the factory. If the driver is to be field
mounted, consult AC Fire Pump for
recommendations. AC Fire Pump cannot
assume responsibility for final alignment.
Use blocks and shims under the baseplate for support at the
anchor bolts and midway between bolts, so as to position the
baseplate approximately 1 inch [25.4mm] above the concrete
foundation, with studs extending through holes in the base
plate, as shown in Fig. 7.
By adding or removing shims under the base, level and
plumb the pump shaft and flanges. The baseplate does not
have to be level.
Draw anchor nuts tight against base, and observe pump and
motor shafts or coupling hubs for alignment. (Temporarily
remove coupling guard, see section 8.2 Coupling Guard, for
checking alignment.)
If alignment needs improvement, add shims or wedges at
appropriate positions under the baseplate, so that
retightening of the anchor nuts will shift the shafts into closer
alignment. Repeat this procedure until a “reasonable
alignment” is reached.
NOTE:
Reasonable alignment is defined as that which is
mutually agreed upon by pump contractor and the accepting
facility (final operator).
Check to make sure that the piping can be aligned to the
pump flanges without placing pipe strain on either flange.
Pour grout in the base plate completely (see section 7.4
Grouting) and allow grout to dry thoroughly before attaching
piping to pump. (24 hours is sufficient time with approved
grouting procedure.)

7.4
Grouting
Grout compensates for uneven foundation, distributes the
weight of the pump unit, and prevents shifting. Use an
approved, non-shrinking grout, after setting and leveling the
unit, (see Fig. 7).
Build a strong form around the foundation to contain the
grout. Soak the top of the concrete foundation thoroughly,
and then remove any surface water. The base plate should
be completely filled with grout.
After the grout has thoroughly hardened, check the
foundation bolts and tighten if necessary. Check the
alignment after the foundation bolts are tightened.
Approximately 14 days after the grout has been poured or
when the grout has thoroughly dried, apply an oil base paint
to the exposed edges of the grout to prevent air and moisture
from coming in contact with the grout.
