4.0 INSTALLATION.
4.1 UNPACKING AND HANDLING.
Where ever possible the food mixer should be transported to the installation position in
the packaging provided to avoid damage. Do not use a sharp knife to cut into the box as
damage to the machine may occur. Check for possible shipping damage. If the unit is
found to be damaged, save the packaging material and contact your nearest Hobart sales
office.
Caution: The mixer is a heavy object and must be correctly handled and lifted
to avoid personal injury.
5
With the machine in the vicinity of its final position remove from the transportation pallet
following the instructions provided with the packaging. The machine is affixed to the pallet
by four retaining bolts through the pallet into the threaded feet.
Care must be taken during this operation to ensure: -
a) All required safety measures are taken to ensure correct lifting and handling to avoid
risk of injury through dropping, falling and tilting.
b) No damage occurs to the machine, which could impair the normal operation.
The top cover is packed separately within the main carton. Only fit the top cover once the
mixer is in position. Do not lift or manoeuvre the mixer by using the top cover.
4.2 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 is restricted to trained personnel.
Select a suitable flat level surface that can support the weight of the mixer and bowl
contents when full (refer to table 1 for weights and dimensions). In areas where stability
may be an issue, the machine should be secured in position.
Ensure there is sufficient space around the mixer to enable safe operation of the bowl lift
handle, attachment hub (if fitted) and removal/replacement of the mixing bowl. Servicing
may be more difficult because of reduced clearances and you should always check that
equipment specifications permit the close proximity of other equipment. Refer to figure 1
for the overall dimensions of the mixer. Service access is required to the rear and top of
the mixer.
4.3 ELECTRICAL INSTALLATION.
The electrical installation of the mixer must conform to the local electricity board
regulations. When installed in the United Kingdom the installation must be in accordance
with the current edition of the IEE Regulations for electrical equipment in buildings and the
Electricity at work act.
A competent person must carry out the electrical installation.
The technical data shown in table 1 details the electrical requirements for the various
mixer options.
The HSM30, HSM40, NCM300 and NCM400 mixers are ‘class I’ appliances where the
protection against electric shock does not rely solely on basic insulation. An external
electrical isolator and MCB/fuses (both items supplied by others) must be fitted to the
incoming electrical supply to the mixer. In addition a 30mA residual current device is
strongly recommended to provide extra protection.
Note: The single-phase model must not be installed via a 13 amp fused plug.
