If the heating element is working or storaged in the high humidity,the insulation will be lowered.
If the sudden access to high voltage, it is easy to cause leakage, short circuit and other conditions
The heater element which has been idle for a long time must be moisture-proof and placed in a ventilated and dry place to ensure the insulation of the product.
Concerning the heating element that has been damp, do not worry too much, after the moisture in the heater evaporates, the insulation performance will gradually recover, and the low voltage can be used to start.
