Installation
Check the following before beginning installation:
Insulation resistance measurement
Place the pump on a dry surface. For this test neither the motor nor the cable should be
immersed in water. Use a megger to measure the insulation resistance between ground and each
phase of the motor. Do the same with any two phases until all pairs are completed. The megger
should indicate an insulation resistance of no less than 20 mega ohms. While taking the
measurement, keep the power supply cable off the ground.
Installation
1. WARNING: Under no circumstances should cable be pulled while the pump is being moved
or installed.
Attach a chain or rope to the grip and install the pump.
2. This pump must not be installed on its side or dry operated.
Ensure that it is installed upright on a secure base.
3. Install the pump in the tank where there is the least turbulence.
4. Install piping so that air will not be entrapped. If piping must be installed in such a way that air
pockets are unavoidable, install an air release valve wherever such air pockets are most likely to
develop.
5. Do not permit end of discharge piping to be submerged, as backflow will result when the
pump is shut down.
6. WARNING: Do not operate the pump for more than 2 minutes with the water level near the
lowest water level(H1) as shown on Fig.1.
7. Use Fig. 2 for set up of floats to maintain safe operating water levels.
H1 : Lowest water level (Motor flange)
H2 : Operating water level
This must be above the top of the motor.
