Installation, Piping and Wiring

Installation
1
Choose a place which has an
ambient temperature below
40°C
and a relative humidity less
than
85%, and is convenient for
maintenance and checking. The
pump must not be installed
outdoors without suitable
protection.
2
To prevent dry running, install the
pump in a position lower than the
surface of the liquid in the tank on
the suction side (Flooded suction).
3
In case it is necessary to install an
S type pump in a position in which
the inlet of the pump remains
higher than the liquid surface (a
suction lift), refer to the
illustrations opposite. In this
position, the pump does not suck if
the pump chamber is not wet.
(The T type pumps do not function
on a suction lift.)

Flooded suction
Priming method
(In case the pump chamber is wet)
①There is no liquid in the suction piping
(This is not allowed for the T type).
②There is liquid inside the suction piping.
