5.1 Hazard warnings
Read the chapter 2 Safety instructions,  22 before doing any maintenance
work. This is important for your personal safety.
NOTE
The interior of the measuring unit is temperature-controlled to 20 °C (68 °F).
With ambient temperatures over 25 °C (77 °F), condensation water may develop
on the cool surfaces and cause damage when the measuring unit is opened.
To avoid damage of the measuring unit due to the formation of condensation
water, always wait for the temperature adjustment (function "Öffnen der Mes-
seinheit vorbereiten") to be completed before opening the measuring unit.

liquid, do not use this ChemBag in the Alyza IQ.
 Make sure you don't damage the ChemBags when unpacking them from the
transport packaging.

ChemBags are safely suspended from the supporting rods, and that they are
not pressed or moved while the locking device is open.

Prior to working with any connected ChemBags make sure that the locking
device of the MultiPort valve is closed.
