Safety instructions
WARNING
The vessel may turn over during mounting.
Securing the vessel against tipping is imperative.
Use an appropriate lifting jack.
NOTICE
The bellow and the O-rings are delicate mounting parts.
Do not use sharp-edged tools.
NOTICE
No leak-tightness of the contact surfaces present.
The following contact surfaces must be clean and level to ensure reliable sealing:
between upper plate and vessel foot
between lower plate, adapter plate (if any), and foundation
Note:
The weighing module is delivered preassembled.
The lift-of protector is adjusted in a way that the load cell is unloaded. Thus overloading
the load cell during installation is prevented.
When using adapter plates, a 13mm socket wrench with insert according to
DIN3124(long version) is required for mounting.
