• Store and transport the unit in an upright position.
• Store the unit between -35°C and 50°C.
• Don't expose the packaging to rain or corrosive
atmosphere.
• After unpacking, check that the unit is com-
plete and undamaged.
3 – Installation precautions
Do not braze as long the condensing unit is
under pressure.
Never place the unit in a flammable atmosphere
Place the unit in such a way that it is not blocking
or hindering walking areas, doors, windows or similar.
• Ensure adequate space around the unit for air
circulation and to open doors. Refer to picture1

Installation and servicing of the conden-
sing units by qualified personnel only.
Follow these instructions and sound refri-
geration engineering practice relating to
installation, commissioning, maintenance
and service.
The condensing unit must only be used for
its designed purpose(s) and within its scope of
application.
Under all circumstances, the EN378 (or
other applicable local safety regulation)
requirements must be fulfilled.
The condensing unit is delivered under nitro-
gen gas pressure (1 bar) and hence it cannot
be connected as it is; refer to the «installation»
section for further details.
The condensing unit must be handled with cau-
tion in the vertical position (maximum offset
from the vertical : 15°)
Anticlockwise (open)
Clockwise (Close)
• Ensure a foundation with horizontal surface
(less than 3° slope), strong and stable enough
to carry the entire unit weight and to eliminate
vibrations and interference.
• The unit ambient temperature may not exceed
50°C during off-cycle.
• Ensure that the power supply corresponds to
the unit characteristics (see nameplate).
• When installing units for HFC refrigerants, use
equipment specifically reserved for HFC refri-
gerants which was never used for CFC or HCFC
refrigerants.
• Use clean and dehydrated refrigeration-grade
copper tubes and silver alloy brazing material.
• Use clean and dehydrated system components.
• The suction piping connected to the compres-
sor must be flexible in 3 dimensions to dampen
vibrations. Furthermore piping has to be done
in such a way that oil return for the compres-
sor is ensured and the risk of liquid slug over in
compressor is eliminated.
4 – Installation
• The installation in which the condensing unit is ins-
talled must comply to EEC Pressure directive (PED)
no. 2014/68/EU. The condensing unit itself is not a
