Frequently Asked Questions - CY5002 Vevor

What type of fuel to use?

Use high-quality light diesel. Do not use kerosene, gasoline, vegetable oil or used oil, as this would damage the device and produce odors.

How to install the heater correctly?

Installation must be done by a professional. The heater must be installed horizontally, never on its side. Leave a 10 cm space around for ventilation. The exhaust pipe must be directed outside and be horizontal or sloping downwards.

What to do in case of error code E-3?

Error code E-3 indicates a problem with the glow plug. Check the connection, clean or replace the plug. If the problem persists, the main board may be defective.

How to use the Bluetooth app?

Download the AirHeaterCC app from the App Store or Google Play. Enable Bluetooth on your phone, turn on the heater, then press the OK button on the panel to display the device code. Search for the device in the app and connect.

The heater turns off by itself, why?

Several possible causes: overheating (housing temperature >230°C), carbon monoxide detection (500 ppm), or fan failure (code E-6). Check the air vents and exhaust pipe.

Can I use the heater in an enclosed space?

Yes, provided that the exhaust pipe is outside and the room is ventilated. The built-in CO detector triggers an alarm and stops the device if the concentration exceeds 500 ppm.

How to set the timer?

On the panel, press OK + ▼ simultaneously for 2 seconds. Use ▲/▼ to set the start and stop times. Press OK to confirm. You can also set a weekly schedule via the Bluetooth app.

What to do if the heater emits white smoke?

White smoke indicates an ignition failure. Check the fuel volume (too much oil can flood the plug). Disconnect the oil pipe and restart 2-3 times. Use a hairdryer to blow into the air intake.

How to clean the air filter?

The air filter should be checked periodically. Remove the filter element and clean it with compressed air or replace if dirty. A clogged filter can cause overheating and faults.

Where can I find spare parts?

Use only genuine Vevor parts. Contact technical support via www.vevor.com/support to order parts such as glow plug, oil pump, fan, or sensor.

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 be very hot and could cause a fire. ② With the heater placed outdoors: It's necessary to extend the exhaust pipe to avoid the exhaust from being sucked into the building from the back fan post 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: 12V; Current: ≥20A, either from a direct power source or a battery. If 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 should be >2mm². 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 intense heat 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.

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 may have an unpleasant odor and malfunction during operation.

Emergency response methods for controller alarms

1. When the CO concentration within the detection range of the controller exceeds the limit, the switch will display a fault, the controller indicator light will flash, and the switch will automatically turn off the heater to avoid a continuous increase in CO concentration. Ventilation should be done immediately (if the environment is narrow and conditions permit, open the ventilation openings to create an open environment as much as possible. When the environment is closed or ventilation is inconvenient, it is recommended to increase ventilation equipment to accelerate air circulation and discharge CO gas), and personnel in the environment should evacuate immediately from the environment where the current CO concentration exceeds the standard.
2. If the installation and usage environment is correct, it is recommended that personnel return to the working area and restart to check the CO concentration to see if it meets the standards.
3. During the use of this product, it is important to maintain long-term air circulation and regularly check the concentration of carbon monoxide (international standard 50 mg/m³ ≈ 40 ppm) to ensure personal safety. If symptoms of carbon monoxide poisoning occur (such as dizziness, headache, nausea, etc.), one should immediately stay away from the source of pollution, breathe fresh air, and seek medical assistance.
4. This product uses electrochemical sensors, which are easily affected by local temperature and humidity interference, resulting in a slight impact on detection accuracy. Therefore, to ensure your safety, please use this product objectively and reasonably. Its service life is affected by the environment, and the accuracy of the sensor should be regularly tested. If the error is too large, please replace the sensor.
