1. Bolt the pump down firmly to the mounting surface. Provide for air movement over the electric
motor as required.
The pump is functionally symmetrical so that the suction and discharge ports can be reversed
(with direction of rotation) and the housing (with cover) can be rotated to suit the installation if
required. Refer to Figure 3, for typical installation and the required relation between rotation and
direction of flow.

2. It is recommended to install vacuum/pressure gauges in the suction and discharge lines to monitor
system operation.
3. Keep suction lines short and straight to minimize friction loss to the pump. Make sure that the
pump will not starve or run dry. Flooded suction or gravity feed of fluid to the pump inlet is
preferred and eliminates manual priming.
4. Use only full-bore ball valves or gate valves in the suction piping. If suction strainers are used,
size them to minimize pressure drop and select a type that is easily cleaned. Strainers should be
regularly inspected and cleared of debris as required during operation.

5. Arrange all suction piping and fittings to prevent formation of air pockets. Make sure all joints
are air tight.
6. Flush all suction lines prior to mating up to the pump. Use unions or other appropriate fittings for
ease of maintenance.
