TRANSPORTATION AND INSTALLATION
WARNING!
AC220/230V
power cord
or plug
●
Use a rated outlet with
voltage fluctuation
of less than ± 10%.
●
To prevent electric shock,
never plug in a power
cord under wet
conditions.
●
Install the pump where the pump can be
conveniently checked or
repaired after installation.
If the space for the pump
is narrow, make the room
as described on the figure.
●
If the suction height exceeds 10m, it can lead to the
function of abnormal overpressure or damage to the
product. Use under 1kgf/cm
2
(Example: The maximum height from the suction
must be under 10m)
●
Do not connect to town water directly. It can lead to
malfunction or damage to the product.
●
When the pump is highly likely to suck in dust or
foreign material, install a sand filter.
Failure to do so may cause a decline
in pressure and quantity
of pumped water, and
malfunction of the inverter.
●
Install a stop valve on the suction side and the
discharge side of the pump
for easier pump
maintenance.

Install a breaker of electric leakage
of under 30mA of rated sensitivity
to prevent electric shock.
