(i)All heat pumps have electric heat.
(ii)Minimum voltage on 230/208 volt models is 187 volts; maximum is 253 volts. Minimum voltage on 265 volt models is 239 volts; max- imum is 292 volts.
(iii)Total watts for 7,000 and 9,000 Btu models; add 70 watts for 12,000 and 15,000 Btu models.
(iv)Minimum branch circuit ampacity ratings conform to the National Electric Code. However, local codes should apply.
(v)Overcurrent protection for all units without electric heaters is 15 amps. Overcurrent protection on 265 volt models must be cartridge- style time delay fuses.
