Tab.1
prevent the fluids in contact with the heat exchangers from exceeding the temperature ranges indicated above and from freezing, even when
the unit is turned off.
when there is a hydraulic circuit, do not use fluids other than water or mixtures of water and ethylene/propylene glycol at the maximum
concentration allowed for the components installed and specified in this manual
the machine must only be put to the use for which it was designed; any other uses can be dangerous and will render the guarantee null and
void
carrying out maintenance on the product can be dangerous: in the event of a fault or malfunctioning, please contact an authorised assistance
centre
the installation must guarantee that the temperature of the fluid entering the unit remains stable and within the range indicated; be careful,
therefore, when adjusting any external heat exchanging and control equipment (dry coolers, cooling towers, zone valves, etc.), sizing the
mass of fluid circulating the plant (particularly when parts of the plant are excluded) and installing systems for circulating the required amount
of fluid, in order to keep the temperature of the machine within the allowable ranges (e.g. during start-up).
the packaging used to protect the machine must always be kept out of the reach of children as it represents a hazard
in units with compressors in parallel, do not disable the individual compressors for long periods of time; always respect the demand limit
function
3.6 Environmental information
The cooling circuit contains fluorinated greenhouse gas covered by the Kyoto Protocol. The units may only be serviced and disposed of by qualified
technicians.
The fluorinated greenhouse gases contained in the cooling circuit must not be disposed of in the atmosphere.

POSITIONING
4.1 Handling, lifting and positioning the unit
Before handling the unit, read with care the following instructions, the information on the yellow label on the
product and in the dimensional drawing, and the instruction manual of the lifting equipment used.
Handling and transport must be carried out by qualified personnel using suitable personal protective equipment
and materials suited to the weight and size of the unit.
The units can be lifted using either tubular rods or eye-bolts. Follow the procedure below:
-
Handle the unit at an ambient temperature above -10°C and when there is no wind
-
Make sure that all the panels and connections (bolts, rivets, etc.) are not damaged and are fastened
and secured correctly
-
Use all, and only, the lifting points indicated in the dimensional drawing and marked on the unit
-
Use cables of suitable load-bearing capacity and length, as indicated in the dimensional drawing.
-
Make sure that the cables are securely fastened to the unit:
-
It is obligatory to use a sling bar of suitable weight-bearing capacity to guarantee stability when lifting and to prevent the cables from
coming in contact with the unit
