WIRING DIAGRAM SELECTION
2 6-461.1
Select the correct wiring diagram as follows:
1. Determine the 12 digit unit heater model number. Example: PTS350SS0122
2. Breakdown the model number into the following parts (using the above example):
a. Model: PTS
b. Size : 350
c. Power Code: 01
d. Control Code: 22
3. Review the model number breakdown against Table 2.1 to select the correct wiring diagram.
For the example in Step 2 above, the correct wiring diagram is located on page 6.
4. Review Table 2.2 to determine if any additional wiring diagrams are necessary based on accessories included.

c All propeller models (HD/HDS/PTS/PTC) are Power Code 01 for 115V/60Hz/1ph supply voltage only. To operate the unit on a supply voltage
other than 115V/1ph, an accessory step down transformer is required. Refer to the latest revision of Literature #6-567 for instructions on
properly wiring the unit heater and transformer.
d All blower models (HDB/HDC/BTS) that are operated with a supply voltage other than 115V/1ph, an accessory step down transformer is
required. Refer to the latest revision of Literature #6-567 for instructions on properly wiring the unit heater and transformer.
