WARNING:
Do not operate the dry pumping system with the liing eyebolts ed 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.
4.1 Start up
WARNING:
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:
Aer the power is applied, all mains circuits will be energised.
CAUTION:
The dry pumping system is designed to ride through transient power interrupons
and to automacally restart once the power is restored.
CAUTION:
Do not operate the pump if the pipeline is restricted or blocked as the pump will not
operate correctly and may be damaged.
