WARNING
☞
Read and follow all instructions in this manual.
☞
Inform yourself regarding:
– Hazards which can be caused by the pump;
– Hazards which can be caused by your system.
– Hazards which can be caused by the media being
pumped.
☞
Avoid exposing any part of the body to vacuum.
☞
Observe the safety and accident prevention regulations.
☞
Regularly check that all accident prevention measures are
being complied with.
☞
Do not operate the turbopump with open high vacuum
flange.
☞
Do not carry out any unauthorised conversions or alterati-
ons to the turbopump with TC 750.
☞
When returning the turbopump observe the shipping
instructions.
☞
The turbopump must be anchored in accordance with the
installation instructions (see Section 3.).
☞
Do not disconnect the plug between the TC 750 and acces-
sory components during operations.
☞
Disconnect the voltage supply to the TC 750 before
opening the turbopump.
☞
When working on the turbopump, the high vacuum flange
should only be opened once the rotor is at rest.
☞
When using sealing gas, the pressure in the hose connec-
tion should be limited to 2 bar via the overpressure valve.
☞
If a heater is in use temperatures of up to 120 °C can arise
in the area of the high vacuum flange. Take care to avoid
burns!
☞
During operations temperatures of up to 65 °C can arise in
the lower part of the turbopump. Take care to avoid burns!
☞
Keep leads and cables well away from hot surfaces
(> 70 °C).
☞
Operate the turbopump with TC 750 only in conjunction
with the relevant power supply (accessory).
☞
Without the cover plate for the TC 750 the unit has been
accredited protection class IP 30. When the unit is
operated in environments which require other protection
classes, the necessary measures must be taken. When the
turbopump is water cooled the enclosed cover plate for
the TC 750 must be installed by an electrical specialist, in
order to attain protection class IP 54.
☞
The mains connection must be subject to a safe
connection to the PE (protection class 1).
☞
If the turbopump and the TC 750 are operated separately
(only permissible with the agreement of the manufacturer)
the turbopump must be connected to the PE.
☞
The turbopump and the TC 750 must only be disconnected
from each other when the turbopump is completely at rest
and the TC 750 has been disconnected from the power
supply.
☞
The cause of any operating voltage leakage to earth (red
LED flashes) must be eliminated to avoid the danger of an
electric shock.
☞
The housing screws do not loosen, pull tight, remove or
replace, since otherwise the guarantee for the security of
the turbopump expires.
Modifications reserved.
