INSTALLATION
Table 3 - Checklist of Components
3.3 Locate the GV Pump
Note: If you operate the pump in an environment with an ambient temperature of 41°F (5°C) or lower, contact
your supplier or Edwards for advice.
Refer to Figure 1 . Remove from the fixing-holes (8) the four nuts and bolts that secure the pump frame (9) to the
pallet.
Attach suitable lifting-equipment to the four lifting bolts (5) to move the pump.
Locate the pump as near as possible to the equipment being evacuated so that the Vacuum, Water and Exhaust
connections can be conveniently made. Provide for adequate space for convenient servicing where possible.
The pump should be mounted on a rigid foundation, such as a concrete floor, and made level by shimming or grouting,
if necessary. Mount the pump to foundation without putting a strain or twist in the pump housing. Refer to
Figure 2
for foundation mounting dimensions. Ensure that the surface is clean and free from debris and contamination (such
as oil). Refer to
Figure 1 . Use suitable bolts through the four fixing-holes (8) to secure the pump in position.
Remove cap from exhaust and inlet openings only when ready to make a piping connection. Also remove the plastic
plug (by unscrewing) from the gas ballast valve. When pump is to be subjected to temperatures below freezing, either
drain the water jacket through the housing drain plug to prevent cracking the housing or add anti-freeze to it. Follow
this same procedure for storage.
3.4 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 gearbox oil-level sight-glass (14).
If necessary, pour more oil into the gearbox: refer to
Section 5.3 .

WARNING
Use suitable lifting equipment to move the pump. Refer to Section 2 "Technical Data" for the pump
mass.
WARNING
Ensure that the cooling-air flow around the pump-motor is not restricted by allowing a minimum
gap of 18 inch (450mm) between the motor body and adjacent installations. Failure to do so may
result in the motor overheating causing the electrical supply to be cut off and thus stopping the
pump.
