Refer to the installation diagram below and carefully read the precautions when installing or using:

1. No Side Installation:

※ Side installation of the diesel heater will result in oil leaks inside the machine after a period of use, producing a large amount of smoke and carbon monoxide poisoning. During installation, leave a space of 10cm around the heater to ensure good ventilation.

※ If installing the heater inside a building: ① With the heater placed indoors: Make holes in the wall for the exhaust pipe to be placed outdoors. Pay attention to insulating the exhaust pipe as it can become very hot and could cause a fire.

With the heater placed outdoors: It's necessary to extend the exhaust pipe to prevent the exhaust from being sucked into the building from the back fan position of the heater, which can lead to carbon monoxide poisoning.

Incorrect Installation Direction Correct Installation Direction

2. Precautions for the power supply:

※ The power supply for the diesel heater must meet the following requirements: Voltage: 12-24V; Current: ≥12A, either from a direct power source or a battery. When powered by a battery, do not charge the battery while using the heater, as insufficient current can cause malfunction. Ensure a firm and secure connection to the battery. Using clamps for fixation can result in poor contact.

※ When extending the power cable for the diesel heater, the wire diameter must be >2 mm². Using a thin wire can lead to insufficient current, causing the heater to not work. After connecting, use insulating tape to protect the connection and prevent electrical leakage, which might lead to fires.

※ Do not disconnect the power when the diesel heater is operating at high temperatures. This can cause backfire due to high temperatures. Repeatedly doing so can cause permanent damage. Solutions:

- If power is cut and you immediately turn on the heater: Wait until the internal temperature of the heater has completely dissipated before turning it on for normal operation.

- If the heater is turned on a long time after a power cut: Incomplete combustion inside may produce a large amount of smoke. Wait for the smoke to clear, the heater will automatically start and operate normally.

3. After the heater is installed, you need to manually pump before turning it on:

※ The fuel line of the heater is long. Before initially starting the heater, manually pump oil up to the fuel inlet. Otherwise, when turned on, the heater will take 30 minutes to detect the fuel (during this time, it will continuously check for signal). Once the ignition plug detects the fuel, it will ignite and heat. Refer to the LCD switch user guide for detailed instructions on manual fuel pumping.

※ When manually pumping fuel, pump just up to the fuel inlet. Over-pumping may result in the heater emitting a large amount of white smoke. Quick solution: disconnect the fuel line, turn on the heater and let it stop naturally, then restart it. Repeat the process until no smoke is emitted. Reconnect the fuel line and turn the heater on to resume normal operation.

※ After starting the diesel heater, continuously blow air into the air pipe using an air pump or a high-speed blower until the heater starts and functions normally. If white smoke appears after operating for a period: This indicates that the atomizing net is clogged. Remove the ignition plug, take out the atomizing net, clean its surface or replace it with a new one.

Cautions for Diesel Heater Power Supply:

※ Diesel heater power supply requirements: Voltage: 12-24V; Current: ≥12A; either a power source or a battery. (Avoid charging the battery while supplying power to the heater, as low current may lead to malfunctions. Ensure a secure battery connection without using clamps to prevent poor contact. Using the car cigarette lighter as a power source is not recommended due to insufficient current.)

It is recommended to use high-grade diesel fuel when refueling the diesel heater. Other types of fuels, such as kerosene, vegetable oil, gasoline, waste oil, etc., cannot be used. Otherwise, the heater will have an unpleasant odor and malfunction during operation.
