(6) If the system could be exposed to the freezing temperature in winter, ensure to take measures to
prevent freezing in the pump room or to prevent the pump, sluice valves, piping, and other
devices from freezing.
(7) Use sound-insulating materials for door and walls of the pump room. Especially if there is a risk
that the noise may cause problem, take necessary measures against the noise.
(8) If the pumping liquid is cold, condensation may occur inside the motor while the pump is stopped.
Take measures to prevent condensation, for example, by installing the pump in a sufficiently dry
room or by heating and insulating the motor even when the pump is stopped.
(9) Carry out repair painting at a time interval suitable for the environment of use. Depending on the
humidity, condensation, and other conditions, rust may form on areas such as threaded parts,
worked areas, anticorrosive-coated sections.
(10) Do not put a cover or filter over the motor. Failure to observe this may raise the temperature inside
the motor, thus leading to product damage, fire, or other problems.

Installation procedure
(1) The area and thickness of the foundation concrete must be large enough to withstand the pump
weight and the operating load.
(2) Make foundation holes in advance, according to the drawing or the size of
the actual bolts.

(3) Ensure that the top surface of the foundation concrete is level, and that the
concrete is sufficiently cured before the installation of the pump.
(4) Place the pump on the foundation concrete. At that time, drive a square steel plate and metal
wedges between the common base and the foundation concrete to provide a clearance (about 10
mm to 30 mm) for mortar to be poured into.
Note
The metal wedges are used to adjust the horizontal
level of the pump, and also to sustain the pump
weight and the operating load. Use as thick a wedge
as possible to reduce the total number of pieces.
Uniformly place them close to the foundation bolts so
that the loads are evenly supported.
(5) Fix foundation bolts to the common base with nuts so that they are suspended in mid-air at the
center of each foundation hole.
(6) Place a level on the flange surface to check the horizontality of the
surface. If it is not horizontal, adjust it with metal wedges.
(7) Once the horizontality and verticality are achieved, lay mortar into
the foundation holes, the clearance under the common base, and
the area around the common base. When the mortar has set
completely after a few days, tighten the foundation bolts. (At that
time, ensure to tighten the nuts evenly and gradually.)
