• Detach the machine from its pallet by removing the wooden battens wedging the castors.
• Take the machine off the pallet. Make sure you do this with at least two people in order to lower it as gently as possible onto the floor.

After unpacking your machine, check that it has not been damaged in transit. Notify us of any defects.

Positioning:
In order to achieve excellent performance and long-term reliability, choose a location that is:
Well-ventilated, shielded from direct sunlight and away from sources of heat, with a flat and sturdy surface free from vibration.

Electrical connection:
IMPORTANT : This machine must be earthed.

• It is recommended that the system be protected with a fuse and an RCD.

Your mains electricity supply to the machine must be protected as indicated below:
