TECHNICAL INFORMATION
SAFETY PRECAUTIONS
- Always carry the pump by means of the han-
dles provided.
- The pump must be set in position taking the
upmost care in order to avoid accidental falls.
,
WARNING!
In case of a need to handle the pump after a pe-
riod of operation, it must be left to cool first as the
external surface temperature may be in excess of
60 °C.
TRANSPORT AND INSTALLATION
The pumps are shipped to the customer inside
cardboard boxes.
Total weight of the pack, including the pump, is
about 36 Kg.
The case must be handled with care, using appro-
priate lifting equipment.
CAUTION
When moving the case, ensure that it is securely
bound to the lifting equipment and that the equip-
ment is strong enough to support the weight.
The pump’s working environment is a traditional
industrial environment. Naturally sites with corro-
sive vapors or excessive heat are best avoided.
Room temperature should ideally be between 12
°C and 40 °C.
If the temperature is not inside this range, consult
Varian technical service for the changes required.
Setting the pump in position should be performed
as follows:
- Pump laid on the ground. There are no special
instructions for this type of installation, except
that the floor should be as flat as possible and
suited to bear the weight of the pump (it
should ideally be a concrete floor) and of any
accessories mounted on it. Note that the
pump is stable on its base plate and it should
not be necessary to anchor it to the floor with
bolts and screws; also vibrations to and from
the pump are greatly reduced by the use of
rubber feet.
- Pump off the ground. In this case, the user
must design a suitable support structure, re-
membering the following points:
* the plane supporting the pump must be
perfectly horizontal;
* the structure should be adequately rigid;
* the relevant safety precautions should be
applied.
Note also that the pump should be attached to
the supporting structure after replacing the
rubber feet with special anti-vibration feet,
which should be screwed to the pump base
and to the supporting plane.
After taking the pump out of its packing case, you
are advised to make the following checks:
a. Ensure that the pump has not suffered any
damage during shipping.
b. Check that there are no uncovered or loose
parts.
PRELIMINARY OPERATIONS
Before starting the pump, fill up with lubricating oil
as the pumps are delivered empty.
NOTE
A tin of oil is included in the packing.
CAUTION
Oil must be poured into the casing through the
special threaded plughole and NOT through the
suction line.
,
WARNING!
Take out the protective caps on the suction and
exhaust flanges before doing anything else. In the
event of an accidental start-up, the air inside the
pump could violently expel the protective caps and
harm the operator.
