3.4 Locate the pump
Note: If you will operate the pump in an environment with an ambient temperature of 0 °C (32 °F) or lower,
contact your supplier or Edwards for advice.
Ensure that the cooling-air flow around the pump-motor is not restricted.
1. Refer to Figure 1. Remove from the fixing-holes (8) the four nuts and bolts which secure the pump frame (9) to
the pallet.
2. Attach suitable lifting-equipment to the four lifting bolts (5) to move the pump.
3. Locate the pump on a firm, level surface. Ensure that the surface is clean and free from debris and
contamination (such as oil).
4. Use suitable bolts through the four fixing-holes (8) to secure the pump in position.
3.5 Check the gearbox oil-level
Refer to Figure 1. The pump is supplied filled with oil. Before you operate the pump, check that the gearbox oil-level
is correct: the oil-level must be between the MIN and MAX marks on the bezel of the oil-level sight-glass (14):
see detail C.
If necessary, pour more oil into the gearbox: refer to Section 5.3.
3.6 Electrical connections
3.6.1 Introduction
Note: On 60 Hz pumps, you must make the wiring connections in the motor in accordance with the US National
Electrical code and with approved local and site practices
We recommend that you connect the electrical supply to the pump-motor through a suitable current monitor, and
that you configure the high current setting on the current monitor to switch off the pump-motor at a suitable
overload current. This overload current must not exceed the maximum current rating shown on the rating plate on
the pump-motor.
Note that the general procedure to connect to the pump-motor is given in Section 3.6.2. However, you must refer to
the motor manual supplied with your pump for detailed instructions on how to connect your electrical supply to the
pump-motor.
Use suitable lifting equipment to move the pump. If you do not, you can injure yourself or damage
the pump. Refer to Section 2.3 for the mass of the pump.
Ensure that the electrical installation of your pump conforms to your local and national safety
requirements. It must be suitably connected to a fused and protected electrical supply and a
suitable earth (ground) point.
