WARNING
If the pipe connected to the outlet had a small diameter or
foreign substance inside, it might raise the pressure inside the pipe
and impair the pump operation. A caution shall be required.
a pressure gauge on the exhaust side of the auxiliary pump, when
the exhaust port pressure 0.03MPaG (0.3 kg
pressure) or more, please provided an interlock which the auxiliary
pump and the pump is stopped . In a state in which the auxiliary pump
is stopped, and to operate the pump, it will be the cause of the
internal pressure of the rising pump damage.
There is a risk that the pressure inside the Vacuum pump rises up to
cause break or oil leak of the casing or Oil level gauge resulting in
CAUTION
Wash sufficiently inside the Vacuum
chamber, pipes, Vacuum valve
and so on to connect them to the Pump. If dirty unit were connected,
it would cause a trouble such like raise the ultimate pressure or
extend the depression time to the specified pressure. Wear a pair of
gloves to touch any vac
uum section. Do not touch with the bare
hand.
Pay attention not to give damage to the Flange sheet face, Gasket
slot or gasket itself.
Use a pipe having bellows between the b
acking pump and outlet of
the Mechanical Booster Pump
so as to avoid any direct load to the
Pump flange.
Do not connect directly the backing pump inlet with the outlet of the
Mechanical Booster Pump.
Use the flange for connection between the pump Outlet and the piping.
