5.2 Mechanical installation
Fig. 1
Correct installation
The foundation must be at least 3 to 6 inches longer and wider
than the base plate. The mass of the foundation must be at least
1.5 times the total mass of the pump and base plate assembly. In
installations where noiseless operation is particularly important,
we recommend a foundation with a mass up to 5 times that of the
pump and base plate assembly. The pump may be fastened
directly to an existing concrete floor if the floor meets the criteria
of a foundation.
To properly hold the base plate to the foundation, proper anchor
bolts are required. For proper holding of the base through the
foundation, the bolt length must extend from in the foundation,
the base height, and 0.25" - 0.50" above the nut. These anchor
bolts are embedded in the concrete floor or foundation, and must
be positioned according to the bolt manufacturer's instructions.
To assist in the proper location of the bolts, a template can be
formed. The bolt locations must be double-checked with drawings
and base.
Bolt sleeves can be used to allow final positioning of the bolts.
The sleeves are a minimum of 3 times larger than the bolt, and
have a length of at least 10 times the diameter. Figure
2 (b)
shows the anchor bolt and the bolt sleeve in which it is installed.

When the anchor bolts are in position, the pump can be placed on
the foundation. The base plate can now be leveled using shims, if
necessary, so that it is completely horizontal. See fig.

WARNING
Incorrect or inappropriate installation of the pump
may lead to personal injury or death.
We recommend that you always use Grundfos
accessories to avoid malfunction due to incorrect
installation.
CAUTION
Material damage may occur due to inappropriate
mounting of the pump.
