Protection
It is essential that the solution level covers the heated portion of the element at all times otherwise element overheating will occur. The use of LOW LIQUID LEVEL CUT-OUT is advised, particularly where tanks are made of, or lined with plastic.
Before removing heaters from a tank, they should be switched off and electrically isolated and remain immersed for a suitable period to ensure no undue temperature rise that may contribute to permanent failure.
Metal sheathed and Teflon coated heaters must be effectively earthed and be installed in accordance to current IEE wiring regulations for electrical installations.
To provide enhanced operator protection, it is recommended that a suitable residual current device with rated tripping current of 30mA or less be incorporated in the supply to the heater.
Further guidance on the installation and use of immersion heaters is available in the BNCE 'Safety Guidelines for Industrial Electric Immersion Heaters'.
