slack joints or couplings.
Maintenance technicians must:
•
be aware of all applicable national directives
concerning accident prevention during work
on motor-driven pumps and should know how
to apply them;
•
have read and understood all the sections on
“Safety Rules";
•
be familiar with the essential design features
and operation of the pump;
•
know how to use and consult the pump docu-
mentation;
•
be concerned about proper operation of the
pump;
•
make a note of any irregularities in operation
of the pump and take the necessary action,
where appropriate.
Use original spare parts wherever possible and
repair a broken part as best as possible on site or
send it back to the manufacturer for repairs.
For all problems arising, or to order spare parts,
refer to our service department.

LUBRICANTS
It will be readily understood how important ade-
quate lubrication is to high technology pumps like
the Varian vacuum pumps. Correct use of appro-
priate lubricants makes a significant contribution to
achieving best performance and warding off de-
fects.
When handling lubricants, the following sanitary
protection measures should be observed at all
times:
•
Avoid prolonged, excessive or repeated con-
tact of the skin with products for lubrication,
and also avoid directly inhaling the fumes or
vapors of such products.
•
Protect the skin by wearing appropriate
clothes and equipment (e.g. special suits,
glasses or, where permitted by the safety
regulations, gloves) or by applying a special
protective product.
•
Clean the skin carefully after contact with the
lubricants by washing freely with water and
soap.
•
Apply a skin cream after washing.
•
Take off and change clothes or shoes on
which oil has been spilled.
•
Never put rags dripping with oil into the pock-
ets of your clothes.
When disposing of waste lubricants, observe the
following environment protection regulations:
•
The lubricants risk contaminating the water
and the ground! Therefore never pour lubricat-
ing products on to the ground, into water or in
the sewage system. All violations of these
rules are liable to persecution as provided for
by law. When using lubricants always keep oil
can nearby.
•
Take care in draining off waste oils. In dis-
posal of these products respect all regulations
in force concerning waste oil disposal.
The recommended lubricating oil is the Varian Ro-
tary Vane Fluid MS1 Type. The Rotary Vane Fluid
MS1 Type is a general purpose mechanical pump
fluid specifically engineered to provide superior
performance in high speed direct drive mechanical
pumps.
These precisely distilled fluids (100% solvent re-
fined neutral paraffinic oil) deliver lower base pres-
sure capability, faster pump-down cycles, and
reduced maintenance requirements on both the
pump and the fluid.
It is absolutely necessary to continue using the lu-
bricants initially used to fill the tank. If this is not
possible for organizational or business reasons,
use only products with the same characteristics as
the previous oils.
Only use of lubricants of suitable quality will guar-
antee safe operation of the pumps.
CAUTION
Mineral oils and the PFPE oil are incompatible. To
change from one type to another, the pump must
be stripped down completely and all parts washed
carefully to eliminate all oil residues.
If you expect to have to use other lubricants, first
find out if the two products are compatible. In cas-
es of doubt, the lubricant used up to that time must
be flushed out by way of a pump flushing proce-
dure.
CAUTION
To avoid the risk of contaminating the oil, absolute
cleanliness of the pump and surrounding area
must be ensured during the lubrication proce-
dures.
Pumps must be filled with MS-1 Varian oil only.
