Correction factors at other entering conditions:
1. Capacities are in MBH (kW), thousands of Btu
per hour (kiloWatts).
2. MBH (kW) values are based on a
∆
t (temperature
difference) of 110°F (61°C) between entering air
and entering water. For other
∆
t's; multiply the
MBH (kW) values by the factors below.
3. Air Temperature Rise.
4. Water Temp. Drop.
5. Connections: 1 Row 1/2" (13), 2 and 3 Row 7/8"
(22); O.D. male solder.
