Information
OS.85 and OS.95 and HS.95:
The ECO connection is located on the top side of the compressor housing; a swan neck pipe for protection
against oil migration is therefore not required. Route the line from the connection horizontally or downwards.

• Solder the ECO suction gas line directly into the ECO shut-off valve.
• In systems with high refrigerant charge: Install suction accumulator upstream of the suction gas connection of
the compressor.
