• EMBRACO shall not under any circumstances be liable if the installation and maintenance are not carried out in
accordance with the instructions given in this manual.
1.4 Cautions
• Units in the application must be used within a working range specified by manufacturer.
• Refrigerant going into suction line must be in vapor stage.
• Give special attention to the correct welding or other forms of connecting joints in the system to avoid the
possibility of leaks.
• Use a leak detector suitable for the respective refrigerant to guarantee the maximum efficiency in controlling leaks.
• Avoid damaging of the unit label during the assembly process.
• Good refrigeration practice suggests system evacuation from both the low and the high side, achieving a minimum
level of 0,14 mbar.
• Use the unit only with electrical components specified by the manufacturer. The electrical box of the compressor
should be located in a position where a safe distance from any plastic, foam, wire or any other flammable material is
ensured. The electrical box should not be placed close to any water tray, close to insulation of suction tubes or close
to electrical connections or application wiring.
1.5 Disposal
• If the machine is placed out of service, it is necessary to disconnect it from the mains . The gas contained inside
the system not be dispersed into the environment. The compressor oil is subjected to differentiated waste collection
regulations; therefore we recommend that you do not dispose of the unit as normal iron scrap but that you use a
special collection centre, as per standards and regulations in force.
Read carefully the following instructions before assembly and putting into operation this condensing
unit.

3. INSTALLATION
3.1 Unpacking.
Before unpacking the unit, check that the packaging has not been damaged in any way and that
the exterior is in good conditions
3.2 Handling.
The packaged condensing unit can be lifted by forklift or pallet truck. The unit should therefore be
