Installation
Splinter guard
2.3 Connecting the MAG to the
vacuum chamber
The MAG is shipped in a sealed PE bag with desiccant. Do not open the
package until immediately before installing.
Do not remove the covers and blanking flanges until you are ready to make
the connections, to ensure that the MAG is installed under the cleanest
possible conditions.
Pay attention to maximum cleanliness when connecting.
Remove the transport seal from the intake flange. To do so unscrew the
screws (30/2) and remove the aluminum cover. We recommend saving the
transport seal for maintenance.
Foreign objects entering the pump through the high-vacuum flange can
cause serious damage to the rotor. That’s why the splinter guard must
always be installed.
Damages caused during operation without the splinter guard are excluded
from warranty.
The pump must be securely attached. If the pump should sud-
denly seize, inadequate attachment could cause the pump to
break away or allow internal pump parts to be discharged. Never
operate the pump (in bench tests, for instance) without its being
connected at the vacuum chamber.
If the pump should suddenly seize, a high decceleration torque will
have to be absorbed by the system. To accomplish this, use all
bolts provided by Leybold for fastening the high-vacuum flange or
use bolts of the prescribed quality; see also the Fig. 20 to 29 and
31 to 33.
Pumps with ISO-K flange must not be attached with clamps.
