34 = 3.4 KW
Voltage 50 = 5.0 KW
K = 208/230V - 1PH - 60Hz R = 265V - 1PH - 60Hz
Notes & Comments
Note Units Affected Note or Comment
Heat Pump All Identifies the parts or components used specifically in the heat
THC units pump units. All other components are consistent with all other
units.
Note 1 Identifies the parts or components used specifically in units built
A, B & C suffix prior to August 1997 (serial prefix JGHP.....)
Note 2 All Identifies the parts or components used specifically in units built
C suffix only starting September 1997 (serial prefix JGJP.....) to current.
Note 3 All The thermostat was changed from the original that had a short
A & B suffix only 3/8” diameter bulb to the thermostat that has a long 1/4” bulb.
Both have the same operating range. If changing from the 3/8”
bulb this kit is required.
