Performance Data
Low Vertical Cabinet and Low Vertical Concealed
AHRI cooling performance is based on 80/67°F entering air temperature, 45°F entering chilled water
temperature with a 10°F ΔT.
Heating performance is based on 70°F entering air temperature, 180°F entering hot water
temperature with a 30°F ΔT.
All performance measured on high speed tap, 115 V, zero ESP, with throwaway filter. Free discharge
EC motor. See Table 6, p. 25 for performance groupings.

Note: Q/ITD = MBh (kW)/(Entering water temperature - Entering air temperature) when ∆T and gpm (L/s) remain constant. To determine heating capacities
at a different entering water temperature or entering air temp, compute the new ITD and multiply it by the Q/ITD shown.
