11.2 Acoustic pressure level
The machine was designed and manufactured in order to reduce the its noisiness at the source.
Measurements performed in the operator’s position on a machine of the same series determined some values.
TEST DOCUMENTS AND CERTIFICATES OF THE TOOLS ARE HELD BY THE COMPANY TELME S.P.A.,
AVAILABLE TO ANY CONTROL AUTHORITY.
12 CARRYING AND UNPACKING
Note: We suggest you to let the Technical Service or qualified technicians carry out the transportation, unpacking
and installation.
TO LIFT THE MACHINE ALWAYS USE AN ADEQUATE LIFTING MACHINE.
ATTEMPTING TO LIFT IT MANUALLY IS DANGEROUS AND CAN DAMAGE YOUR HEALTH.
The machine’s weight specifications, both inclusive of packaging and net, can be
found in both the supplied documents and on the packaging itself.
To prevent the oil contained in the compressor to flow into the refrigerating circuit, it is necessary to
always keep the machine in upright position, both during carrying and during the installation and operation. Always follow the instructions on the packing.

12.1 Transportation of the packed machine
The packing has been projected to assure at the machine the highest protection.
It is therefore suggested to transport the machine while it is packed as near as possible
at the place where it will be installed.
To carry the packed machine, use an elevator, or a bench trolley, inserting its forks in
the basement’s holes.
12.2 Unpacking
- WOOD PACKING: unnail the top panel, then separate the lateral panels.
- CARDBOARD PACKING; cut the strips and remove the cardboard from the top;
After having opened the packing, make sure the machine isn’t damaged. In case of doubt, do not use it, and call the Seller.
THE OPENING OF THE LATERAL PANEL IS ONLY ALLOWED TO THE TECHNICAL SERVICE OR TO
QUALIFIED TECHNICIANS AND MUST BE MADE BEFORE CONNECTING IT. MAKE SURE NOT TO DAMAGE THE INTERNAL PARTS OF THE MACHINE.
- Remove both the lateral panels unscrewing the relevant fixing screws [21];
- Find and unscrew the bolts [22] which fix the machine’s frame at the packing’s basement;
The outlet of the supply cable is placed on the machine’s lower side. During the lifting make sure not to
damage it.
- Lift the machine from the basement, possibly working on the lower side, near the wheels, and however, only on the
frame’s carrying parts. Remove the basement, and lean the machine on the floor avoiding bumps;
DO NOT insert objects, ropes or brackets for the lifting THROUGH the machine, since these could
damage the inside parts.
- Re-close the lateral panels;
- Replace or move the packing, which is produced with entirely recyclable materials (
).
