The Sunster 12V 5KW Water Heater is an advanced parking heating device designed to preheat your vehicle's engine and interior. It operates using your vehicle's onboard battery and fuel (gasoline or diesel), employing a combustion and heat exchange principle to circulate and heat the engine's coolant system. This system ensures stable operation even in extreme cold, down to -40°C, provided the correct fuel is used.
The heater offers versatile control options including manual start, timed start, remote control start, and mobile remote start, adapting to various heating requirements. By heating the antifreeze, the system gradually raises the temperature of both the engine and the vehicle's heating system. Once the water temperature reaches approximately 80°C, the heater automatically stops, and the remote control will indicate that the heating cycle is complete.

2. Коопсуздук маалыматы жана сактык чаралары
- Күйүүчү май түрү: Only one type of fuel (gasoline or diesel) can be used. Once a fuel type is introduced, do not mix or switch to another fuel type. For example, if gasoline is used, do not subsequently add diesel.
- Күйүүчү майдын сапаты: To ensure optimal performance and normal heating in cold conditions, use only high-quality fuel appropriate for the local temperature. Avoid inferior diesel.
- Water Pump and Host Placement: The water pump and the main heater unit (host) must be installed at a position lower than the vehicle's original water kettle, PTC heater, and warm air tank.
- Oil Pump Outlet Angle: The oil pump outlet should be installed at a 45-degree angle upwards, ideally close to the main engine.
- Exhaust Pipe Orientation: The exhaust pipe must face towards the rear of the vehicle and should not point towards the direction of vehicle travel or the ground. Ensure it does not come into contact with flammable materials.
- Intake Pipe Connection: The intake pipe should only be connected to the vehicle's original air filter. Do not obstruct the intake pipe or cover it. It must not be installed in the same direction as the exhaust pipe.
- Орнотуудан кийинки текшерүү: After completing the installation, thoroughly inspect all connecting parts to ensure the circuit is properly connected and there are no oil leaks or blockages in the oil circuit.
- Коргоо өзгөчөлүктөрү: The heater is equipped with low voltage protection to prevent excessive battery consumption and overheating protection for safe operation.
