5.1 Setting up the pump
Installation location Observe the following requirements when setting up the pump:
● Consider the load-bearing capacity of the installation site.
● Maximum installation altitude 2000 m (above mean sea level)
● Permissible ambient temperature: +12 ... 40 °C
● Maximum relative humidity 85%
Fill up with operating fluid before operating the first time (see p. 14, chap. 5.5).
– Amount and type according to rating plate
Always place the pump on a firm, even surface.
– The base frame has four holes for anchoring onto the base.
When installing the pump in a closed housing, ensure there is sufficient air circulation.
– Sight glass and gas ballast valve must be visible and readily accessible.
– Voltage and frequency information given on the motor rating plate must be visible.

5.2 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.
