Notes
- Always ensure air is flowing before powering the heating element
- Regulate the ramp up time using the potentiometer to control the AC voltage
- Requires a temperature controller with 100ms cycle time
- Temperatures are measured by 3/16” “K” T/C sensor Part #F039272 mounted inside TC holder #F029485
- TC Holder mounted on exit of #F029763 Housing Assembly
- Use of other sensor types and mounting locations can result in heater damage
- Minimum airflow for accurate control is 60 SCFH Maximum air temperature is 1500°F (815°C) *3.6kW, 2-Stage F060418
- Operating above this curve voids the product warranty
