Model Number Description
Nameplates
The RTWD/RTUD unit nameplates are applied to the
exterior surface of the control panel door.
A compressor nameplate is located on each compressor.
Unit Nameplate
See Figure 1. Unit nameplate includes the following:
• Unit model and size descriptor.
• Unit serial number.
• Identifies unit electrical requirements.
• Lists correct operating charges of R-134a and Oil 48.
• Lists unit test pressures
• Identifies installation, operation and maintenance and
service data literature.
• Lists drawing numbers for unit wiring diagrams.
Compressor Nameplate
Compressor nameplate includes the following:
• Compressor model number.
• Compressor serial number.
• Compressor electrical characteristics.
• Utilization Range.
• Recommended refrigerant.
Model Number Coding System
Model numbers for unit and compressors are comprised
of numbers and letter which represent equipment
features.
See “RTWD Model Number,” p. 7 and “Compressor Model
Number,” p. 8 for details.
Each position, or group of positions, in a number or letter
is used to represent a feature. For example, from the chart,
we can determine that “F” in digit 8 of unit model number
indicates unit voltage is 460/60/3.
ASME Nameplate
The ASME nameplate is different for the evaporators,
condensers (RTWD only) and oil separators.The
evaporator nameplate is located on the left portion of the
shell.The insulation over the nameplate is intentionally
left unglued, for ease in viewing the nameplate.
The condenser nameplate is on the backside of the
condenser below circuit 2 compressor.
