Do's and Don'ts:
- Please take care while fixing heaters and selecting watts, check Volts rating of heaters before connection. Heater rated for particular volts should never be connected to higher volts rating.
- These heaters are rigid and heat transfer is by conduction from inside surface so perfect matching of dia is important. Heater should be fastened tight without air gap. Heater fixing surface should be perfect. Mica nozzle heaters should be tightened again after set temperature is reached as mica heater expands a bit. this will ensure better life.
- No foreign materials such as polymer, oil ,water etc, should fall over mica and ceramic nozzle heaters they should be well covered.
- For Sealed type and spiral nozzle heaters it's not a problem they work in such conditions.
- Choose appropriate watts as per calculation. Under rated watts will result in heater failure.
- Temperature control should be taken care. For higher temperature application do inform us while ordering.
