Installation procedure
(1) The area and thickness of the foundation concrete must be appropriate for the pump weight and the
operating load.
(2) Make foundation holes in advance so that they match the drawing or the actual dimensions of the
pump.

(3) Make sure that the top surface of the foundation concrete is level, and
properly cure the concrete before installing the pump.
(4) Place the pump on the foundation concrete.
In doing so, insert a square steel plate and metal wedges between
the common base and the foundation concrete to create clearance
into which mortar is to be poured. (A clearance of approximately
10 mm to 30mm)
(5) Fix foundation bolts with nuts to the common base so that they hang
at the center of the foundation holes.
Note
The metal wedges adjust the horizontal level of the pump, and withstand
the pump weight and the operating load. Use metal wedges as thick as
possible to reduce the number of them.
Uniformly place them near foundation bolts.
(6) Put a level on the flange surface to check that it is vertical. If it is
not vertical, adjust it with metal wedges.
(7) After checking verticalness, pour mortar into the foundation
holes and the clearance around the lower part of the common
base.
After it has hardened completely, tighten the foundation bolts.

Precautions for connecting the ducts
Caution
Before piping work, remove the dust caps from the suction side and
the discharge side of the casing of the pump. If the pump is operated
with them attached, the pump, pipes, etc. may be damaged.
Caution
Do not screw the pipe when the companion flange is attached to the
pump. The pump may be damaged.
