4. Operations
4.1. Filling In The Lubricant
Turbopumps must be filled with lubricant before
being operated.
If possible fill in the lubricant in the fitting
position of the turbopump.
Pumps are designed to operate with Lubricant “F3”,
contained with the delivery 40 ml (see type plate).
If “F3” is heated above 300 °C, toxic vapours
which can harm the airways are given off. Do
not allow “F3” to come into contact with tobac-
co products (danger of poisoning when ignited).
The precautions necessary in the handling of
chemicals must be observed.
Filling in the lubricant
➡
Unscrew lubricant filler screw 71 and, using the syringe
provided, inject approximately 40 ml of lubricant.
Where the set-up position is vertical or
horizontal the maximum lubricant level in the
sight glass is the lower edge of lubricant filler
screw 71.

PLEASE NOTE
WARNING
CAUTION
4.2. Before Switching ON
Sections 4.2 to 4.6. refer only to operating the pump in its
condition on delivery, without the DCU/HPU operating unit.
The bridges ”venting release”, ”motor, TMP ON” and
”pumping station ON” are fitted in the remote control plug.
Please refer to Section 4.8. regarding the switching on with
the Display And Operating Unit DCU/HPU.
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!
Take care when pumping hazardous gases and
observe the safety precautions of the gas
manufacturer!
➡
With sealing gas: Open the sealing gas supply.
➡
Open cooling water supply and check flow.
➡
Plug connecting cable 8a (see Section 11. Accessories)
into the TC 750 and connect with Power Unit TPS 600 on X2
(please see Section 3.6.).
The following pre-settings have been
programmed:
– Start-up time
11 min
– Rotation speed switchpoint
80%
– Automatic venting
50%
These settings can only be altered via Serial Interface RS 485
(DCU, HPU or PC); please refer to the respective operating
instructions.

PLEASE NOTE
WARNING
WARNING
➡
Screw back in lubricant filler screw 71 with the O-ring 75.
It is essential to ensure that the lubricating
pump is not over-filled with lubricant.
Overfilling will cause the excess lubricant to be
secreted from the hole for the lubricant filler
screw 71.
If necessary, dismantle the lubricating pump
from the pump and fill up with lubricant (see
Section 8.3.).
