2. Release the pressure and remove the test instrument.
To remove the instrument from the system, use the appropriate size
of spanners on the top secon of the pressure connecon and on the
body of the instrument only. Ensure that the lower part of the pressure
connecon is not rotated as this may release it from the base.
3. The system is now ready for use.
CAUTION!
If the volume required to be illed is very large requiring the use of an

at all mes otherwise a high pressure can be built up on the low pressure
ram of the screw press and damage caused. To ensure this does not
happen we can supply the system i ed with a relief valve, which will
release at a set pressure, should the valve operaon be incorrect.
Alternavely, we can supply a modi ied system and hand pump for this
f
operaon. For f rther informaon on both items contact

DRUCK & TEMPERATUR Leitenberger GmbH.
When tesng equipment with a large volume, the capacity of the screw
pump (65 cm³) may be insu cient to reach the pressure required. In this
ffi
case, the equipment should be illed as far as possible with the liquid
f
before connecng it to the system, so that the displacement needed is
reduced.
Dirty or chemically contaminated test items should not be i ed as they
f
contaminate the system unless they are irst cleaned.

Wear safety goggles!
Protect eyes from lying parcles and liquid splashes.
