• Your exhaust pipeline system must be
designed so that the pressure in the pipeline
during pump operation is less than 1.15 bar
absolute (1.15 x 10
5
Pa, 862 torr). If the
pressure in the pipeline is higher than this
pressure, the pump will operate at a high
temperature and may trip because of
excessive electrical current consumption.
• Ensure that debris (such as weld slag) cannot
get into the pump during operation.
If necessary, contact BOC Edwards or your supplier
for advice on inlet isolation-valves, outlet check-
valves or other components suitable for your
application and system design.

1. Use a fork-lift truck or a pallet truck to place
the pallet in a convenient position.
2. Remove the cardboard sleeve which covers the
pump, then remove the protective foil bag from

3. Inspect the equipment. If the pump or any of the
other items is damaged, notify your supplier and
the carrier in writing within three days; state
the Item Number of the pump together with
your order number and your supplier’s invoice
