PTC coolant heater installation precautions
PTC water heater can provide heat for the cockpit of new energy vehicles and meet the standard of safe defrosting and defogging. It also provides heat to other parts of the vehicle that require temperature regulation, such as the battery.
1. Product Installation Precautions
1.1 Before powering on, pay attention to the firm installation and reliable connection of the connectors (the main high voltage cannot be reversed, otherwise the control will fail, and the control board will be damaged if it exceeds 1 minute).
1.2 The grounding wire is connected reliably to prevent static electricity from damaging components.
1.3 Antifreeze must not contain impurities to prevent clogging of the water tank.
1.4 After unpacking, be sure to check whether there is any external damage caused by transportation. Damage caused by improper installation and use (including use and installation conditions beyond the scope specified in the specification) is not covered by the warranty.
2. Precautions for the use of PTC water heaters
2.1 After the heater is connected correctly, it is recommended to turn on the low-voltage power first and then the high-voltage power when it is powered on.
2.2 The water flow in the water cycle is ≥ 4L/min. If the flow is too low, frequent temperature protection will occur.
