The machine includes parts subject to PED EU directive 2014/68/EU, Pressure Equipment
Directive. PED directive regulates all the pressurized part defining for them categories based on
volume-pressure ratio and based on fluid refrigerant type. Those parts then have not to be anyhow
modified nor removed. Under the responsibility of the owner, the machine and parts falling in
the scope of PED shall be checked either during commissioning and periodically fulfilling local
country regulations and norms. Parts in the scope of PED are:

Machine handling

The unit should normally be moved on flat surfaces with a maximum slope of 15 ° and on the four
wheels, avoiding excessive shaking. When stopped then the brake on the front wheels must be
inserted. On slightly irregular surfaces, the unit can be moved by keeping it slightly inclined and
grounded on the two rear wheels by making sure to have a firm grip on the rear handle.
CAUTION: Although heavier components of the unit are installed on the bottom of
the unit in order to lower as much as possible the center of gravity, it's however not
completely removed the risk of overturning.
