There is a corrugated hose with an inner diameter of 25 millimeters in the installation component. According to the installation situation, the shortest length of the combustion-supporting air duct cannot be less than 20 centimeters, the maximum length of the combustion-supporting air duct cannot exceed 1.5 meters. Fix it on the heater with a pipe clamp and another end is fixed to the vehicle body with a bracket.

3. Installation of heater exhaust device

The direction of installing the exhaust port should not face the airflow and should not be blocked by dirt such as mud, rain, or snow.
The installation component contains an exhaust pipe with an inner diameter of 25mm and a length of 40cm. Depending on the installation situation, the exhaust pipe can be shortened to 20 centimeters or extended to a maximum of 1 meter.
Fix one end of the exhaust pipe to the heater with a pipe clamp, and fix another end to the vehicle body with a racket

4. Installation and precautions for dosing oil pump

The installation of the oil circuit should preferably be tilted upwards to facilitate the discharge of gas from the oil circuit. Pay attention to checking the vent holes of  the fuel tank to avoid negative pressure in the oil tank. Oil pipelines should be located away from heat sources, and should not be installed near silencers, exhaust pipes, etc. They should be protected with corrugated pipes and bundled at suitable places with a spacing of no more than 50cm. Installation diagram of electromagnetic pump:
Installation angle of metering oil pump
When installing the metering oil pump, always pay attention to the upward inclination of the oil nozzle, and the installation angle should be greater than 15°. Priority should be given to the installation angle between 15° and 35°.

1. Itis not allowed to select installation angles between 0° and 15°
2. Prioritize the installation angle between 15° and 35°.
3. Allow selection of installation angles between 35° and 90°.
   Connection of oil pipes
   When connecting the oil pipe, after inserting the heater oil nozzle, oil nozzle of the oil pump, oil extractor, and T-shaped tee oil nozzle into the rubber, a seamless connection should be formed with the oil pipe inserted at the other end to avoid the formation of bubbles in the oil circuit, generating noise, and affecting the combustion effect.
   

Precautions for installation of T-shaped tee components for oil extraction
The oil extraction tee must be connected between the original vehicle oil tank and the original vehicle oil pump. It is prohibited to connect between the fuel pump and the engine of the original vehicle to prevent injecting the fuel into the heater by high pressure of oil pump of the original vehicle, causing great danger. Vehicles with the original oil pump installed in the fuel tank cannot use a T-shaped tee for oil extraction. Instead, an oil extractor should be used to directly extract oil from the tank.

5. Installation and precautions of oil extractor

For fuel tank oil extractor, at the time of installation, the length of metal suction pipe can be cut on the site, Then seal and connect it.
When installing the machine, open a 10mm hole on the upper end face of the oil tank to remove burrs; cut off oil tank oil extractor with an appropriate length (keep a distance of 10-20mm between the bottom of the suction pipe and the bottom of the oil tank). Install the oil extractor, install the sealing ring and pressure plate at a time, adjust the oil outlet direction properly, and lock it tightly at last.
When connecting the oil pipeline, each jaint should be sealed to prevent air leakage and fuel supply failure, Pay attention to checking the air vent of the fuel tank.
The fuel pipe should be kept away from the heat source to avoid damaging the pipeline.

Heater debugging after installation

After the installation of the heater, it is necessary to exhaust first to fill the water pump with anti-freeze solution and fill the entire pipeline with anti-freeze solution. After the installation of the heater is completed, the engine can be started and the water pump of  he engine can fill the entire parking heater and pipeline with water. Increase the throttle appropriately to facilitate the discharge of gas generated in the pipeline during installation.
Pay attention to checking the liquid level of the water tank and add an appropriate amount of anti-freeze solution to avoid water shortage in the water tank, which may cause the heater to malfunc- tion. It is strictly prohibited to start the heater when there is no water.

Heater operation and function display

The liquid heater is started in one click mode and fully automatically controlled. Users can operate the entire heating process of the heater only through the heater run switch.
Firstly, before starting the heater for heating, check if there are any leaks in the various pipelines (including water pipes and oil pipes) of the heater.
When the switch is turned on to the heating position, the heater begins to detect its own components.
After the components are normal, the ignition plug is preheated for 60 seconds and ignites. When the sensor detects stable combustion of the flame inside the heater, the ignition is successful and normal combustion begins. If the first ignition fails, it will automatically enter the second preheating ignition process.
If the second ignition fails and the controller enters self-protection, please check if the relevant components are properly connected.
After normal combustion of the heater, it will continue to heat the anti- freeze solution. When the water temperature at the outlet of the heater reaches 70°C, the heater automatically reduces its power and slowly heats. The heater stops supplying oil and burning when the water temperature reaches 80°C.
The fan motor stops working after a delay of 3 minutes, and the water pump is still rotating. When the water temperature drops to 60°C, the heater automatically starts heating. If the user does not need the constant temperature function, turn off the switch and the heater will exit the constant temperature state, ending the heating work. During the heating period, it is prohibited to turn off the power switch of the entire vehicle (if the fan and water pump are suddenly turned off during the heating process, the high-temperature gas in the heater will stay and even flow in the opposite direction, which will burn out the control and other components). Turn off the heating switch and wait for at least 3 minutes. The power supply can be cut after the fans and water pump stop.

Repair and maintenance

After using the heater in winter, it should be removed from the vehicle for cleaning and maintenance. Usually, there is no need for major repairs during a heating season. If there is a significant decrease in thermal efficiency, difficulty in ignition, or other faults, the cause should be promptly identified and eliminated
If excessive carbon deposition causes a decrease in thermal efficiency, the cooling fin on the inner wall of water jacket and the carbon deposition in the combustion chamber should be deaned.
The oil tank, oil pipe, and oil filtering device should be kept clean and unobstructed, and cleaned regularly according to the actual situation
The parking heater circulation system should use anti-freeze solution or a mixture of anti-freeze solution that is suitable for the ambient temperature as the coolant medium During the season when the parking heater is not in use, the power supply of the parking heater should be disconnected, and the parking heater should be kept clean and dry. It is strictly prohibited to immerse the heater in water, rain, and prolonged exposure to direct sunlight. It is best to activate the heating function 1-2 times a month, with each healing lasting at least 5 minutes.

Measures for heater failure
