Mica Heater Installation Guidelines
- Unpackage Mica Heater and inspect for any shipping damages. Do not operate damaged equipment.
- Verify marking for watt and volt rating and compare to your supply voltage and capacity.
- Mica Heaters should be installed on smooth clean cylinders or flat surfaces.
- When putting Mica Heaters on barrel or nozzle, do not open the heater for installation. This can damage the mica and cause premature failure.
- Make sure the Mica Heater is seated properly and the clamping band tightened as much as possible.
Optimizing Heater Performance
- Use the correct Mica Heater diameter on the application to ensure proper fit.
- Retighten Mica Heater clamps after being energized and cooled.
- Avoid excessive torque on post terminals. Use a wrench to hold the bottom nut while loosening/tightening the top nut. 20 In-lb max torque on post terminal nuts.
- Do not allow contaminants such as dirt, oil and plastics to collect on Mica Heaters. These materials can carbonize and cause electrical shorts.
- Avoid moisture and splash down areas. Moisture could be wicked up by the leads or get into the inside of the heater causing the heater to fail.
- Max Pressure for Mica Strip Heaters is 150 PSI.
- Maximum sheath temperature is 900°F.
