• 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.
