Safe use and installation of air duct heater

1. Although the electric heater of the air duct is equipped with a thermal protector, which can automatically cut off the power supply, it is only used when there is wind in the air duct. It is necessary to avoid the accident of the heater. Before heating, all relevant components should be checked to be in a normal state to ensure the normal operation of the fan before the electric heater can be put into use, thereby eliminating the possibility of ultra-high temperature without air drying. It is recommended to control the fan together.
