Setting up the pump
When installing the pump, observe the following conditions:
Always place the pump on a firm, even surface.
– Check the load-bearing capacity of the floor at the installation location.
– The vacuum flange serves as the reference surface.
– A drilled hole is provided on each foot for attachment to the mounting surface. Do
not distort the pump when screwing on.
When installing the pump in a closed housing, ensure there is sufficient air circulation.
– Both sight glasses must be visible and accessible for inspection and maintenance
purposes.
– Voltage and frequency information given on the motor rating plate must be visible.
Where stationary installation is involved, anchor the pump on site.
Fill up with lubricant before operating the first time
.
– Amount and type according to rating plate
