Edwards T-STATION 85

Connect to the vacuum system
WARNING:
Connect the turbo pump inle
t to the vacuum system before applying power to the T-
Staon 85. This will ensure that the pump cannot operate accidentally causing injury.
WARNING:
If ins
talling the vacuum system directly onto the T-Staon 85, the weight of the system
must be no more than 10 kg and the centre of gravity must be posioned laterally within
the bounds of the base plate. If this is not the case, the vacuum system must be supported
to ensure that the T-Staon 85 does not topple.
1. The turbo pump can be securely xed to the vacuum system via the inlet ange. Make
sur
e that the pump inlet and all components ed to the pump inlet are clean and
dust-free. If the pump inlet is not kept clean, the pump down me may be increased.
2. If the pump has a CF ange, use the copper compression gasket supplied with the
pump and use a full complement of bolts to connect the inlet ange of the pump to
the vacuum system.
3. If the pump has an ISO ange, use a minimum of four claw clamps (each torqued to
10 Nm) to connect the inlet ange of the pump to the vacuum system. Alternavely,
use a rotatable collar and the combined inlet screen and trapped O-ring supplied with
the pump to connect the inlet ange of the pump to the vacuum system; use a full
complement of bolts with the rotatable collar.
4. If the pump has an NW ange, use the centring ring supplied with the pump and a
metal NW clamp to connect the inlet ange of the pump to the vacuum system.
5. All inlet ange bolts must be re-ghtened once the system is under vacuum. Ensure
that no torques or other forces are transmied to the pump from the vacuum system
or the associated pipelines.
Connect to the exhaust extracon system
WARNING:
V
ent dangerous gases and gas mixtures safely. Do not expose people to these gases. If
pumping hazardous gases or vapours, observe the safety recommendaons of the supplier
of the gas/vapour.
Note:
This secon applies to E2M1.5 versions only.
The exhaust system must be congured so that the maximum pressure at the pump outlet
does not e
xceed 0.5 bar gauge (1.5 bar absolute, 1.5 x 10
5
Pa) at full pump throughput.
1. Make sure that the exhaust pipeline cannot become blocked.
2. If using an exhaust isolaon valve, make sure the pump cannot be operated with the
v
alve closed.
