POSITIONING
All of the operations illustrated in this section are to be exclusively carried out by specialised technicians, those who have to
organize the different operative sequences and the use of suitable means to act at all times within the rigorous application
of current standards regarding this matter.
The following requirements
must be met before installing
the machine in the
establishment:
1. That the network voltage coincides
with the one indicated on the
identication label.
2. Operating room temperature:
20°C and 40°C
68°F and 104°F.
3. Must be installed in a place
where it can be monitored by
qualied personnel.
4. It must be placed horizontally
on a solid, at and stable surface.
5. Easy access to the plug.
6. That the laws and current
technical standards are complied
with when carrying out the
installation.
Once the machine has been received, it must be moved to the place where it will be installed:
1. Make sure that nobody is within the lifting and load movement operation radius and, in particularly difcult situations,
use personnel who control the movements to be carried out.
2. Moving the machine must be done by at least two people in a vertical position.
3. Avoid bumpy routes, paying attention to the dimensions and possible protruding parts.
4. It is prohibited to make additional cuts in the packaging.

During the periods when the establishment
is closed, it is possible to use the machine in
maintenance mode. In this way, you will save
a considerable amount of electrical energy
as the compressor only operates during the
strictly required time to maintain the right
temperature for the product(max. 3ºC)
(max. 37.4 ºF).
