Housing 2 with CAJ/TAJ compressors)
• Fully pre-wired electrical panel (including main
switch, compressors contactor, overload relay)
2 – Handling and storage
• It is recommended not to open the packaging
before the unit is at the final place for installation.
• Handle the unit with care. The packaging al-
lows for the use of a forklift or pallet jack. Use
appropriate and safe lifting equipment.
• 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 corro-
sive atmosphere.

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 pic-
ture1 for minimal values of distance to walls.
• Avoid installing the unit in locations which are dai-
ly exposed to direct sunshine for longer periods.
• Avoid installing the unit in aggressive and
dusty environments.
• Ensure a foundation with horizontal surface
(less than 3° slope), strong and stable enough
to carry the entire unit weight and to elimi-
nate vibrations and interference.
• The unit ambient temperature may not ex-
ceed 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
refrigerants 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 com-

personnel only. Follow these instructions
and sound refrigeration engineering practice
relating
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.
Picture 3
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°)
pressor must be flexible in 3 dimensions to
dampen vibrations. Furthermore piping has
to be done in such a way that oil return for the
compressor 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 EEC Pressure direc-
tive (PED) no. 97/23/EC. The condensing unit
itself is not a "unit" in the scope this directive.
• The unit must be securely installed on a stable
and rigid support, and fixed from the begin-
ning. See picture 2.
• It is recommended to install the unit on rub-
ber grommets or vibration dampers (not
supplied).
• Slowly release the nitrogen holding charge
through the schrader port.
• Connect the unit to the system as soon as pos-
sible to avoid oil contamination from ambient
moisture.
• Avoid material entering into the system while
cutting tubes. Never drill holes where burrs
cannot be removed.
• Braze with great care using state-of-the-art tech-
nique and vent piping with nitrogen gas flow.
• Connect the required safety and control de-
vices. When the schrader port is used for this,
remove the internal valve.
• It is recommended to insulate the suction
pipe up to the compressor inlet with 19 mm
thick insulation.
