Selection & installation notes
- The EC supply image includes DC, while prose says AC only. Confirm the complete heater/fan supply compatibility before DC operation; the stated 265 V maximum is not a new nominal supply rating.
- The source Class II label and generic grounding instruction are inconsistent. Follow the exact heater terminal markings and insulation design, and bond the cabinet as required.
- Use ON/OFF temperature control; the source excludes PWM or voltage-dimming power control. Allow for PTC cold-start current and coordinate supply switching and fuse protection.
- Mount vertically with warm air upward and clear space around the outlet. Do not cover or touch hot surfaces. Repeated thermal trips require investigation before reuse.
- Both fan versions list 5000 h; a longer EC fan lifetime is not established by the comparison table.
