1/1
The pumps are designed so as not to present a
thermal risk for the user's safety. However, specific
operating conditions can generate temperatures which
require particular care to be taken by the user (external
surfaces > 70°C).
Avoid moving or causing a shock on a pump in
operation.
There is a risk of seizing if the pump rotates in an axis
perpendicular to its axis of rotation.
First pump start-up
Safety instruction
for use
When the pump is new, or after a prolonged shut-down
of 3 months or more (under normal storage conditions),
Alcatel recommend operating the pump at atmospheric
pressure for 10 minutes (inlet and exhaust open to
atmosphere) in order to ensure a slow rotation and
grease re-distribution in the pump ball-bearings.
For this operation, inlet and pump exhaust are open to
atmosphere.
The access to the rotor of a turbomolecular pump
with an unconnected inlet is dangerous.
