Pressure Balance
CPB 3000

3. Commissioning and Operation

3.1 Preparation

3.1.1 Setting up the Device

Set up the pressure balance on a solid surface. If it is not resting on a solid foundation or is
subject to vibrations, measurements could be affected. This should be avoided.
If no temperature control system is present, the device should at least not be placed near a heat
element or window. This will reduce drafts and warm air flows as much as possible.
The water level should be used to align the device. At this time, rough alignment can already be
performed without the piston cylinder system. Using the rotating feed, position the device so that it
is horizontal.
Place the star handle with knobs onto the spindle pump. Ensure that the spring-loaded thrust pad
engages into the star handle bushing.
Remove the blind plugs from both pressure connections.

3.1.2 Filling in of operating liquid (first commissioning)

As an operating liquid only the included hydraulic oil is suitable for the CPB
3000.
Other pressure transmitting media are available on request.
Fill the pressure balance with the operating liquid as follows:
Turn the spindle completely clockwise.
Open the shut-off valve of the reservoir and unscrew it completely, then remove the top cover of
the reservoir.
Pour the operating liquid carefully and slowly, alternating between both pressure connections. You
can monitor how the operating liquid settles into the reservoir. Pour the liquid into the pressure
connections until the reservoir is ½ to ¾ full.
Put the reservoir cap back on and fit the shut-off valve. However, leave the valve open!
