7. INSTALLATION
A qualified person must install this machine in accordance with current regulations.
7.1. UNPACKING AND HANDLING
Wherever possible, the mixer should be transported to the installation position inside its packaging to avoid any damage.
Do not use a sharp knife to open the box to prevent damaging the machine. Upon the first inspection, check for any
possible shipping damages. If any damage is found, save the packaging material and contact us.
Caution: The mixer is heavy and must be correctly handled and lifted to avoid personal injuries.
When the machine is in the vicinity of its final position, remove from the transportation pallet. The machine is fastened to
the pallet with four retaining bolts reaching into threaded feet of the base. Care must be taken during this operation to
ensure:
•All required safety measures are taken to ensure correct lifting and handling to avoid risk of injury, which may be
through dropping, falling or tilting.
•No damage is done to the machine which could impair its normal operation.

7
7.2. LOCATION
The mixer is not suitable for outdoor installation and must not be installed where a water jet could be used for cleaning.
The mixer must only be operated by trained staff and must be installed in an area where the use and maintenance are
restricted to trained personnel.
Ensure that the mixer is at a height with the bowl handles approximately between knuckle and elbow height. This will
reduce the need to bend at waist level.
Select a suitable flat level surface that can support the weight of the mixer and bowl contents when full. It is
recommended to secure the mixer in position. Ensure the table, stand or work surface is firmly fixed to the floor. The
appliance must be restrained to prevent any movement during use.
Ensure that there is sufficient space around the mixer to ensure the safe operation. Servicing may also become an issue if
there is a greatly reduced clearance. For this reason, ensure that service access on the top, side and rear of the mixer are
clear.
7.3. ELECTRICAL INSTALLATION.
The electrical installation of the mixer must comply with the local or national electricity board regulations.
A competent person must carry out the electrical installation. Ensure that the electrical supply agrees with machine
specifications prior to connecting it.
The mixer is a Class l appliance, since the protection against electric shock does not rely solely on basic insulation. An
external electrical isolator and MCB/fuses (both supplied by others) must be fitted to the incoming electrical supply of the
mixer. In addition, a 35 mA residual current device is strongly recommended to provide extra protection.
“This appliance should be connected to a supply source with an impedance value Zsys less than (0.05+j0.03) Ω.
If the supply cord is damaged, it must be replaced with a special cord or assembly available from the manufacturer or its
service agent.”
