*Assumes all customer connections are on the same end of the chiller.

**Height is for chiller without unit-mounted starter.

†Heat exchangers are rated for typical applications at AHRI Conditions (44F leaving chilled water and 2.4 gpm/ton in the evaporator, and 85F entering condenser water with 3.0 gpm/ton flow in the condenser).
