4.3 Locate the pumping system
WARNING: HEAVY OBJECT
Risk of injury or damage to equipment. Heavy objects can cause muscle strain or back
injury. The mass of the pumping system will differ depending on the model supplied.
Make sure that 2 person lift the pump together. Do not use crane to lift the pumping
system.
CAUTION: OVERHEATING
Risk of damage to equipment. When locating the pumping system, care should be
taken not to restrict the ventilation grid located under the base of the system. Failing
to observe this may result in overheating of the turbomolecular pump.
The turbo pump used on the pumping system stores a large amount of kinetic energy
when it is running at full speed. In the unlikely event of a malfunction (rotor seizure), the
stored energy could cause a slight movement of the pumping system platform. If the
pumping system is operating on a bench top:
A.
Position the pumping system at least 10 to 15 cm away from the edge of the bench
top and adjacent devices
B.
Tether or fix the pumping system to the bench top. Refer to
page 19.

Note:
Straps or screws cannot be provided as the best type fixing for the customer bench top
location cannot be determined. Sourcing or fabricating these fixings locally is

4.4.1 Bench top fixing with straps
1.
Locate the pumping system on your bench. We recommend to locate the system at
least 15 cm from the bench edge.
2.
Lead the straps through prepared windows in base plate. It is necessary to use 2
straps with safety load limit of at least 2500 kg to ensure that the system is fixed
securely. If you will use 2 straps but only in one string, the safety load must be
minimum 5000 kg.
