5.1 Setting up the pump
Installation location
Observe the following requirements when setting up the pump:
• Note the load-bearing capacity of the mounting surface.
• Maximum installation altitude 2000 m (above mean sea level)
• Permissible ambient temperature: +12 ... +40°C
• Maximum relative humidity 85%
Fig. 5: Setting up
Î
Fill up with operating fluid before operating the first time
.
– Amount and type according to rating plate
Î
Always place the pump on a firm, even surface.
– Where stationary installation is involved, anchor the pump on site.
Î
When installing the pump in a closed housing, ensure there is sufficient air cir-
culation.
– Sightglass 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
Î
Before attaching the piping at the vacuum flange remove locking cap and insert
protective strainer with the respective O-ring.
Î
The connection between the pump and the recipient should be kept as short as
possible.
– Depending on the pump type, use metallic hoses or PVC hoses with flange
connections.
– Separators, filters etc. may be installed upstream to protect the pump (see ac-
cessories). However, please observe the loss of pumping capacity due to the
conductivity of the accessories.
If a protective strainer is inserted into the intake port, the suction capacity loss is
negligible.
