. The instrument should be installed on a clear, level and stable platform, which
should be close to the water source and draining sink. The distance from the instrument to the water
valve, draining sink and power supply should be shorter than one meter to ensure the convenient
operation. The distance between the instrument and the wall or other devices should be at least 40 cm.
For your safety, do not store anything on top of the instrument or any container, chemical agent or
devices etc. behind the instrument.
The pressure and temperature of the water supply should meet the certain requirement, and the water
should be clear and free of impurities (see Chapter 2 Item 2 for details). The draining sink should be
lower than the discharge outlet of Kjeldahl Distillation Unit to ensure the good water-discharging
performance.
