When lifting the pump, use appropriate crane (or hoist) and lift system, check position and tightness

of lift system so that weight of the pump is not UNBALANCED.

Failure to observe this precaution can result in serious accidents.

Handle the cables very carefully. If they are bent or pulled excessively, the cable and the moulded

seal may be damaged, resulting in insulation failure. Also, care is needed to protect cable ends

against water intrusion.

Installation

2. Pump installation:

1. Clean the installation area.

2. 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.

3. This pump must not be installed on its side. Ensure

that it is installed upright on a secure base.

4. Install the pump at a location in the tank where

there is the least turbulence.

5. If there is a flow of liquid inside the tank, support the

cable where appropriate. (See Fig. 1)

6. 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.

7. Do not permit end of discharge piping to be sub

merged, as backflow will result when the pump is

shut down.

8. These pumps do not have an automatic operating

system based on built-in floats. Do not operate the

pump for a long time 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. 2 and maintain a safe

operating water level.

Before installation check rotation. Correct rotation is clockwise when viewed from top of motor. Read

ELECTRICAL WIRING.

Keep hands completely away from grinder impeller when making this check.

: Operating water level

This must be above the top of the motor.

: Lowest water level (motor flange)
