3.0 Installation

!

NOTICE

The descriptions and instructions included in this manual are for a typical pump
installation.  Documentation specific to this pump installation has been included
in the Attachments section.  This section is located at the back of this manual.
Please refer to the Attachments section for installation-specific information.

3.1

Unpacking and Initial Positioning

•

  Carefully unpack the pump.

•

  Check for signs of possible damage in shipment.

•

  Notify the Ebara representative immediately if there are any signs of damage.

3.1.1

Pump Location

Locate the pump in an area that is:

•

  Free from excessive dust and moisture.

•

  Easily accessible to allow the pump to be serviced.

•

  Less than 40°C/104°F ambient temperature

3.1.2

Leveling Pads

•

  Extend the leveling pads and level the pump.

Each castor includes an adjustable pad that extends, making the pump immobile.
Adjust the pads to level the pump.
The pump must level.  The castor provides an adjustment range of about 15 mm.

3.1.3

Shipping Hardware

On 6-stage pump packages, the upper pump (fore pump) is secured with four yellow
shipping brackets.  These are used to prevent the rubber cushions from tearing away
during shipment.  The brackets need to be disconnected from the pump and rotated
away from the pump.

For each bracket:

1.  Remove the bolt securing the bracket to the pump (upper bolt).
2.  Loosen the bolt securing the bracket to the frame.
3.  Rotate the bracket away from the pump.
4.  Tighten the bolt securing the bracket to the frame.
5.  Reinstall the upper bolt into the pump housing.

If the pump is to be shipped for any reason, these brackets should be reconnected
before moving the pump.
