GENERAL INFORMATION
This equipment is destined for use by professionals. The user
should read this instruction manual and any other additional in-
formation supplied by Varian before operating the equipment. Var-
ian will not be held responsible for any events occurring due to
non-compliance, even partial, with these instructions, improper
use by untrained persons, non-authorized interference with the
equipment or any action contrary to that provided for by specific
national standards.
The TV 301 Navigator is an integrated system with a turbo-
molecular pump for high and ultra-high vacuum applications with
its relevant controller. The system can pumps any type of gas or
gas compound. It is not suitable for pumping liquids or solid parti-
cles. The pumping action is obtained through a high speed turbine
(max. 56000 rpm) driven by a high-performance 3-phase electric
motor. The TV 301 Navigator is free of contaminating agents and,
therefore, is suitable for applications requiring a "clean" vacuum.
It is equipped with auxiliary connectors to supply an additional fan,
to control the vent valve, to be controlled from a remote site by
means of an host computer connected through a serial line
(RS232 or RS485).
The following paragraphs contain all the information necessary to
guarantee the safety of the operator when using the equipment.
Detailed information is supplied in the appendix "Technical Infor-
mation".
This manual uses the following standard protocol:
!

The caution messages are displayed before procedures which, if
not followed, could cause damage to the equipment.
NOTE
The notes contain important information taken from the text.
STORAGE
In order to guarantee the maximum level of performance and reli-
ability of Varian Turbomolecular pumps, the following guidelines
must be followed:
•
when shipping, moving and storing pumps, the following en-
vironmental specifications should not be exceeded:
•
temperature range: -20 °C to 70 °C
•
relative humidity range: 0 to 95% (non condensing)
•
the turbomolecular pumps must be always soft-started when
received and operated for the first time by the customer
•
the shelf life of a turbomolecular pump is 10 months from the
shipping date.
!
CAUTION
If for any reason the shelf life time is exceeded, the pump has to
be returned to the factory. Please contact the local Varian Vacuum
Sales and Service representative for informations.
PREPARATION FOR INSTALLATION
The TV 301 Navigator is supplied in a special protective packing.
If this shows signs of damage which may have occurred during
transport, contact your local sales office.
When unpacking the system, be sure not to drop it and avoid any
kind of sudden impact or shock vibration to it.
Do not dispose of the packing materials in an unauthorized man-
ner. The material is 100% recyclable and complies with EEC Di-
rective 85/399.
!
CAUTION
In order to prevent outgassing problems, do not use bare hands to
handle components which will be exposed to vacuum. Always use
gloves or other appropriate protection.
NOTE
Normal exposure to the environment cannot damage the TV 301
Navigator. Nevertheless, it is advisable to keep it closed until it is
installed in the system, thus preventing any form of pollution by
dust.
INSTALLATION
Do not install or use the pump in an environment exposed to at-
mospheric agents (rain, snow, ice), dust, aggressive gases, or in
explosive environments or those with a high fire risk. During op-
eration, the following environmental conditions must be respected:
−
maximum pressure: 2 bar above atmospheric pressure
−
temperature: from +5 °C to +35 °C (see the diagram pres-
sure-temperature in the appendix “Technical Information”)
−
relative humidity: 0 - 95% (non-condensing)
In the presence of magnetic fields the pump must be protected
using a ferromagnetic shield. See the appendix "Technical Infor-
mation" for detailed information.
The TV 301 Navigator must be connected to a primary pump (see
"Technical Information").
The TV 301 Navigator can be installed in any position. Fix the TV
301 Navigator in a stable position connecting the inlet flange of the
turbopump to a fixed counter-flange capable of withstanding a
torque of 1000 Nm around its axis.
!
CAUTION!
Do not remove the adhesive and protective cap before connect-
ing the turbopump to the system.
