(1) Under no circumstances should the cable be
pulled while the pump is being transported or
installed. Attach a chain or rope to the grip and
install the pump.
(2) This pump must not be installed horizontally.
Ensure that it is installed upright on a secure
base.
(3) Install the pump at a location in the tank where
there is the least turbulence.
(4) If there is a flow of liquid inside the tank,
support the piping to prevent abnormal
vibration. (See Fig.2)
(5) Install piping so that air will not stagnate
(6) Do not permit end of discharge piping to be
submerged. A backflow will result when the
pump is stopped.
(7) Manual type pumps do not have an automatic
operating system based on built-in floats. Do
not operate the pump more than ten minutes
with the water level near the minimum
operating level as the automatic cut-off switch
incorporated inside the motor will be activated.
To avoid dry operation, install an automatic
operating system, as shown in Fig.3.
Water levels H1 and H2 are shown in the
following table.
(8) When using electrodes for automatic operating
system, incorrect actuation may occur caused
by scum and oil attached on the electrodes.
(9) Installation of the pump with quick discharge connector shall be performed according to the
manual ”Quick Discharge Connector “
Packing materials after installation, and wasted lubricant oil and grease, and parts after
inspection and repair shall be transferred to a qualified waste-treatment contractor observing
the applicable laws and the regional regulations.
Install a stand-by pump preparing for an accidental stop of the operating pump.
There is a possibility of suspension of water supply to stop the facilities.
