Plus • 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
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 picture
1 for minimal values of distance to walls.
• Avoid installing the unit in locations which are
daily exposed to direct sunshine for longer pe-
riods.
• Avoid installing the unit in aggressive and dus-
ty environments.
• 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
installed must comply to pressure Equipment
Directive (PED) 2014/68/EU. The condensing unit
itself is not a "unit" in the scope this directive.
• It is recommended to install the unit on rubber
grommets or vibration dampers (not supplied).
• It is possible to stack units on top of each other.

• When stacking, the topmost unit must be secu-
red to the wall, as shown in picture 2.
• Slowly release the nitrogen holding charge
through the schrader port.
• Connect the unit to the system as soon as pos-
