Cooling MBH based on 8 °F entering air temperature, 50% RH, and rated air flow.
KW includes compressor, outdoor fan and indoor blower motor watts. Add-on coils include 365 watts/1000 CFM for blower motor.
EER (Energy Efficiency Ratio) is the total cooling output in BTU's at a 95°F outdoor ambient divided by the total electric power in watt-hours at
those conditions.
SEER (Seasonal Energy Efficiency Ratio) is the total cooling output in BTU's during a normal annual usage period for cooling divided by the
total electric power
input in watt-hours during the same period.
1.
TXV = Thermal Expansion Valve kit required. Use 1TV700 series kit.
2.
Single phase units require single phase 2HK heaters — Three phase units require three phase 2HK heaters. (29) indicates 460 volt use only.
3.
G2FD coils available with a factory installed horizontal drain pan. Replace "S" with "H" in the model number.
— = Not Applicable.
