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 |
| A, B & C suffix | Identifies the parts or components used specifically in units built |
|
| 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. |
|
|
|
|
265V |
| All | Identifies the parts or components used specifically in units built |
|
| Voltage code R | to operate on 265V 1PH 60Hz (same as 277V 1PH 60Hz) |
