Installation
3.3 Locate the EXPT pumping station
CAUTION
When lifting the EXPT Pumping Station, do not attempt to support the mass of the system from the backing
pump.
CAUTION
When lifting the EXPT Pumping Station, always use slings with sufficient length to prevent damage of the system
components.
Before attempting to lift the EXPT Pumping Station, move the system (on its pallet) close to the operating position.
Ensure that you provide a firm level base before removing the system from its pallet. It is advisable to always use
mechanical lifting equipment when moving the heavier EXPT2 systems. Use slings around the base of the system from
front to back, make sure each sling is routed between the castors or feet and the base guides to prevent slippage.
Alternatively use straps with lifting hooks. Refer to Figure 3 which shows where to locate the slings or lifting hooks.
CAUTION
When locating the EXPT Pumping Station, care should be taken not to restrict the ventilation grid located under
the base of the system. Failing to observe this may result in over heating of the controller and the
turbomolecular pump.
WARNING
Heavy objects can cause muscle strain or back injury. It is advisable to use suitable lifting
equipment when moving the EXPT Pumping Station.
WARNING
(Applicable for systems with base castors) For your safety, both front castors must be locked when
the system is in operation. If you do not and the turbomolecular pump seizes, movement of the
system may damage equipment and injure people.
