CAUTION
Material damage due to incorrect fixation
Defective fixation may limit the functionality of the mixer or damage it.
• If the mixer is fixed to a concrete structure, use anchor bolts for fixation. Follow the
manufacturer’s installation instructions! Temperature specifications and hardening
periods must be strictly observed.
• If the mixer is fixed to a steel structure, ensure that the structure is sufficiently
strong. Use fixation materials with sufficient strength!
Use suitable materials to avoid electrochemical corrosion!
• Tighten all screwed connections. Observe torque specifications.
NOTICE
Use only properly functioning lifting equipment!
Use only properly functioning lifting equipment to lift and lower the mixer. Ensure
that the mixer does not become jammed during lifting and lowering. Do
not
exceed
the maximum bearing capacity of the lifting equipment! Check that lifting equip-
ment is functioning properly before use!
ƒ
Prepare the installation site:
–
Clean, free of coarse solids
–
Dry
–
Frost-free
–
Disinfected
ƒ
Work must always be carried out by two persons.
ƒ
Demarcate the working area.
ƒ
Keep unauthorised persons away from the working area.
ƒ
From a working height of more than 1 m (3 ft) above the ground, use scaffolding
with a safety harness.
ƒ
Toxic or asphyxiating gases may build up during work. Ensure adequate ventilation.
Observe protective measures in accordance with work regulations (gas measure-
ment, carry a gas detector with you).
ƒ
Take immediate countermeasures if there is a build-up of toxic or asphyxiating
gases!
ƒ
Install lifting equipment: even surface, clean, firm base. Warehouse and installation
location must be easily accessible.
ƒ
Attach chain or wire rope to handle/attachment point with a shackle. Only use lifting
gear that has been technically approved.
ƒ
Do not stay within the swivel range of the hoisting gear.
ƒ
All connection cables must be laid properly. The connection cables must not pose
any risk (i.e. tripping, damage during operation). Check whether the cable cross-sec-
tion and the cable length are sufficient for the selected installation type.
ƒ
Observe minimum clearances to walls and any fixtures.
