Selection & installation notes
- The image gives 110–120 VAC for the low-voltage version, while the text gives 100–120 VAC. Verify the exact nameplate before selection.
- The text calls the automatic-reset device a thermal fuse; its construction and reset behavior require clarification. Do not bypass protection or assume a fuse resets.
- The text recommends a 10 A time-delay fuse, but inrush duration and protection coordination are not supplied. Confirm protective-device selection for the circuit.
- Airflow, dimensional orientation and mass differ between the table and image. Obtain a confirmed drawing and performance sheet. PTC power varies with ambient temperature and airflow.
- Mount vertically with the outlet upward and keep the airflow path clear. The text reverses inlet/outlet names in one clearance note; use the unit markings.
