Tandem requirements, DSF540E to DSF1590T mounting
For parallel mounting, the compressors can be mounted directly on the rails. Rubber grommets and spacers must be
installed below the rails.
These parts are included in accessories.

Design piping
General requirements
Proper piping practices should be employed to:
Ensure adequate oil return, even under minimum load conditions (refrigerant speed, piping slopes…). For
validation tests see section Manage oil in the circuit.
Avoid condensed liquid refrigerant from draining back to the compressor when stopped (discharge piping
upper loop). For validation tests see section Manage off cycle migration.
Piping should be designed with adequate three-dimensional flexibility to avoid excess vibration. It should not be
in contact with the surrounding structure, unless a proper tubing mount has been installed. For more
information on noise and vibration, see section Sound and vibration data.
