Connecting the vacuum side
Remove locking cap from the vacuum flange;
– pay attention to the cone strainer and the respective O-ring in the intake port.
Clear welded lines of any welding scales, loose parts etc. before installation.
The connection between the pump and the vacuum chamber should be kept as short
as possible.
– Depending on the pump type, use metallic hoses or PVC hoses with flange con-
nections.
– Separators, filters etc. may be installed upstream to protect the pump (see acces-
sories). However, please observe the loss of pumping capacity due to the conduc-
tivity of the accessories.
