GENERAL INFORMATION
This equipment is destined for use by professionals. The user
should read this instruction manual and any other additional
information supplied by Varian before operating the equipment.
Varian will not be held responsible for any events occurring due
to non-compliance, even partial, with these instructions, im-
proper use by untrained persons, non-authorized interference
with the equipment or any action contrary to that provided for
by specific national standards.
The TV 141 Navigator is an integrated system with a turbo-
molecular pump for high and ultra-high vacuum applications
associated with its relevant controller. The system can pumps
any type of gas or gas compound. It is not suitable for pumping
liquids or solid particles. The pumping action is obtained
through a high speed turbine (max. 62000 rpm) driven by a
high-performance 3-phase electric motor. The TV 141 Naviga-
tor is free of contaminating agents and, therefore, is suitable for
applications requiring a "clean" vacuum.
The TV 141 Navigator 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.
The following paragraphs contain all the information necessary
to guarantee the safety of the operator when using the equip-
ment. Detailed information is supplied in the appendix "Techni-
cal Information".
This manual uses the following standard protocol:

CAUTION
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
When transporting and storing the pumps, the following envi-
ronmental requirements should not be exceeded:
−
temperature: from -20° to +70 °C
−
relative humidity: 0 - 95% (non-condensing)
If the storage time is long start the pump using the SOFT
START mode.
PREPARATION FOR INSTALLATION
The TV 141 Navigator is supplied in a special protective pack-
ing. 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
manner. The material is 100% recyclable and complies with
EEC Directive 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
141 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
atmospheric agents (rain, snow, ice), dust, aggressive gases,
or in explosive environments or those with a high fire risk. Dur-
ing operation, 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 In-
formation" for detailed information.
The TV 141 Navigator must be connected to a primary pump
(see "Technical Information").
The TV 141 Navigator can be installed in any position. Fix the
TV 141 Navigator in a stable position connecting the inlet
flange of the turbopump to a fixed counter-flange capable of
withstanding a torque of 221 Nm around its axis.

CAUTION!
Do not remove the adhesive and protective cap before con-
necting the turbopump to the system.
