Unit Installation
Installation Instructions
Recommendation for Interconnection Tubing Installation
Three possible versions are schematically illustrated:
1) The outdoor unit installed above the indoor unit – such installation requires an oil trap in the
gas line at the lowest point of the riser. The radius of the oil trap should be as short as
possible. Horizontal runs of liquid line should follow the gas line (except for trap). In case the
insulation must be partially removed for installation purposes, it is imperative that lines be fully
insulated after the installation has been completed.
2) The units are installed at the same level – no
trap is required.
3) The outdoor unit is installed below the indoor
unit – such installation requires an inverted gas
line trap to be installed at the indoor unit. The
top of the trap must be greater than the height of
the indoor unit.
