4. Operations
4.1. Before Switching On
Sections 4.1. to 4.3. refer only to operating the pump in its
condition on delivery, without the DCU operating unit. The
bridges ”venting release”, ”motor, TMP ON” and ”pumping
station ON” are fitted in the remote control plug.
Turbopump rotors rotate at high speed. When
the high vacuum flange is open there is a
danger of injury and of damage to the pump
caused by objects falling into the pump.
Therefore never operate the pump with open
high vacuum flange.
➡
With water cooling: Open cooling water supply and check
flow.
➡
Plug connecting cable 8a (”Accessory”) into the TC 600
and connect with Power Unit TPS 100 on X2 (please see
Section 3.8.).
