Altitude Correction Factors:
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 125°F (69°C) between entering air
and entering water. For other
ţ
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, 3 and 4 Row
7/8” (22); O.D. male solder.
