Data Aire gForce DX - Connection Sizes, Air Cooled Units

26
NOTICE:
1. If equivalent piping length falls between two columns above, choose
the longer equivalent length.
2. Dual circuit units should use the same line size on both circuits.
3. If hot gas line refrigerant flow is upward, use “Vertical Up”.
4. If hot gas line refrigerant flow is downward, use “Horizontal & Vertical
Down”.

* Indicates D = Downflow and U = Upflow Configuration
NOTE: Units will have a liquid line and either a hot gas or suction line.
NOTE: Field connections at the indoor evaporator and remote condenser
will not necessarily be the same as the field pipe size required.
