INSTALLATION

Figure 3 - EXT70/70/200H system fitted to the Waters LCT flight tube
3.3 Connection to the LCT Premier system
The system chamber can only fit on the Waters LCT Premier instrument in one orientation. However, it is possible to
incorrectly fit the integral cartridge pump. The cartridge pump should always be fitted into the chamber with the
exhaust port facing downwards, as shown in
Figure 3 .
The system chamber should be fixed to the LCT Premier using M6 bolts of an appropriate length through all four bolt
holes provided - refer to
Figure 3 .
The system mounting must be suitably rigid and capable of absorbing the rotational energy generated by the unlikely
event of a failure of the pump rotor. Contact Edwards for further information.
3.3.1 Connection of the EXDC160 module
The EXT70/70/200H is supplied with the EXDC160 module fitted. In case of disconnection, the EXDC160 module
mounts adjacent to the exhaust port at the bottom of the pump. Refer to
Figure 3 . The EXDC160 controller has a
keyed, multi-pin circular connector, which requires correct orientation before locking in place.
WARNING
The EXT70/70/200H system weighs in excess of 23 kg. Care should be taken when handling and
moving the system into place. Use suitable eyebolts in the positions included on the system
chamber if necessary.
