Installation
39GA02411_002_C0 - 10/2016 - © Leybold
We recommend connecting the SP-Guard as the monitoring system to the
system controller.
The pump is not suited for pumping of toxic, corrosive, combustible and/or
explosive gas mixtures (except within the permissible scope of pumps cer-
tified in accordance with ATEX Category 3 inside).Pumps without mark-
ing must not be operated with or in explosion hazard atmopheres.
Gas mixtures with an oxygen share of > 21 percent by volume must not be
pumped. We offer special pumps for this purpose.
If mixtures which are not allowed shall be pumped or in case of doubt
please contact Leybold.
The pumps have not been designed to pump liquids. Suitable protection
devices must be provided.
3.3 Connection to the System
Before installing the pump it must be disconnected from all voltage sourc-
es and protected from being switched on inadvertently (lockout/tagout).
Only trained staff may install the pump.
Observe all safety regulations.
The pump must not be operated with an open intake port (risk of suffering
injury by rotating parts which are within reach).
When connecting several pump systems, pressure differences between the
inlet and the exhaust can cause of the rotors to turn without control. Such
operation can cause severe damage and, moreover, presents a risk potential
during maintenance work. Here, if required, the non-return valve should be
used. In the case of parallel operation and larger vacuum chambers, there
exists the risk of backwards running over a longer period of time.
The materials for the connecting lines must be capable of sustaining the
medium which is being pumped.
The pipe connections shall be connected to the pump free of any mechanical
tensions.
