General Information
Model Number Coding System
The model number for the unit is comprised of numbers and letters which
represent features of the equipment. Shown on the chart in Figure 3 are
samples of typical unit model numbers, followed by the coding system.
Each position, or group of positions, in the number is used to represent a
feature. For example, in Figure 3, position 8 of the unit model number, Unit
Voltage, contains the number “4”. From the chart, it can be seen that a “4” in
this position means that the unit voltage is 460/60/3.
