Do not operate the dry pumping system with the lifting eyebolts fitted or with any
enclosure panels removed or damaged. Do not touch any parts of the pump(s)
when the dry pumping system is on. Surfaces of the pumps are very hot and
can cause injury to people.
WARNING:
Do not operate the dry pumping system with any enclosures removed or
damaged as there may be a risk of an electric shock.

Initial start-up
WARNING:
Risk of injury or damage to the equipment.Ensure that it is safe to start the dry
pumping system. Failure to do so (for example, maintenance is being performed
on components downstream of the dry pumping system) could cause injury to
people.
WARNING:
Risk of electric shock. After the power is applied, all mains circuits will be
energized.
CAUTION:
Risk of damage to the equipment. Do not operate the pump if the pipeline is
restricted or blocked as the pump will not operate correctly and may be
damaged.
1.
Check that the electrical connections correspond to the local codes and that
all wires are clamped tight to their terminals.
2.
The installation must be earthed and protected against short circuits by fuses
of the inert type in all phases. It is advised to install an isolating switch near
the vacuum pump.
3.
Whenever electrical connections of motor, fan or converter have been
disconnected, always check rotation direction
4.
Check the process lines for the correct size to prevent high pressure drop and
for cleanliness to protect the vacuum pump. Also check for leaks.
5.
Make sure the pump outlet is not obstructed.
6.
Connect the inlet pipework.
7.
Connect the cooling water and purge gas supply.
