1. Rated working voltage: DC600V
2. Voltage range: DC450v ~ DC750V
3. Working temperature: - 40 ℃ ~ 85 ℃
4. The shell and other materials are die cast aluminum and plastic sprayed silver white
5. The unmarked dimensional tolerance shall comply with GB / T1804-V
6. Medium: coolant, ratio of water to ethylene glycol = 50:50

2.Connection to vehicle cooling system
The heater shall be installed in the vehicle cooling cycle circuit according to the reference. The antifreeze remaining in the whole circulating system shall be kept at least 25L. In the circulation circuit where the heater is located, antifreeze of regular brand shall be used. Poor antifreeze will accelerate the corrosion of the inner cavity of the heater due to high temperature and shorten the service life of the heater. Heater damage caused by scaling, blockage and cavity corrosion caused by poor antifreeze will be excluded from the warranty.Hoses that at least comply with din73411 must be used. The hose shall be laid without kinks to prevent air from entering the connection position of the heater. The heater must be installed below the lowest water level of the circulating water circuit, and it should be repeatedly confirmed whether the clamp is locked firmly to prevent slipping
