-
The
item is fixed at 220v in time of delivery. |
|
|
-
After
cheching up in-put voltage in case
of AC 380V,open up the covering and fix the switch
to
AC 380V when in use.
|
|
|
-
In
case an electric current of motor pump
is under 20A, Direct operation is good,
but in case of over 20A, it is recommandale
to use proper electronic closing device
for longer life-span of the device. |
|
|
-
Method
of connecting wire is the same for water
supply and drainage. |

-
The
length of electrode, E1 is maximum in
water level, and adjust E2 to minumum
in water level.
Plese earth to the maximum length. |
|
|
-
Stainless
steel electrode(∮5) is the most fixable
material, and any electrode should not
move or no bented by the power of streaming
water. |
