2. Installation
- 21 -
[1]
Installation position
• Install the pump as close to the suction tank as possible and in the lowest position available (for flooded
suction).
• If the suction port of the pump is to be positioned higher than the suction tank (for suction lift), be sure to
arrange for a foot valve in the priming pipe and suction pipe.
* The lift head depends upon the liquid properties, temperature, and length of the suction piping. For details of
the setup, consult IWAKI or your dealer.

Indoor and outdoor use
The pump can be operated either indoors or outdoors. However, safety measures should be taken so as not to
expose the motor and power distribution unit to flooding or other natural hazards.
[3]
Installation site
Select an installation site that is flat and free of vibrations caused by nearby machines. Space sufficient for
maintenance work should be provided.
M
Lifting
When lifting the pump, please pay attention to the following points.
•
Pump must be lifted horizontally using two bolts located at pump and motor.
•
In the case that there is no lifting bolt at the motor, rope or such kind materials should be tightenly winded to the
motor to lift the pump horizontally.
•
Please use lifting chain or rope which has enough strength enduring pump weight.
•
To prevent any human body accident caused by the pump drop, please do not enter under the lifted pump.

Foundation preparation (before pump installation)
[1]
The area for anchoring the pump must be greater than the area of the base. If the anchoring area is not enough,
the base may be destroyed due to a concentrated load on it.
[2]
If pump operation is to be subject to vibration (resonation with the piping, for example), provide an expansion
joint between the pump and the piping. Otherwise, the piping, gauge, etc., may be damaged.

Installation advice
• Use anchor bolts to fasten the pump base firmly.
• Install the pump horizontally.
• Sufficient space is required to allow cool air from the motor fan to circulate.
• Allow ample space around the pump for easy and efficient maintenance work.
