4. Setup and Installation
Important Notes
- Professional personnel are highly recommended for installation to ensure proper function and safety.
- Do not run the compressor without adding R134a refrigerant and connecting all other parts. Doing so will cause severe damage to the compressor.
- Ensure the control board is tightened securely. Failure to do so may result in the board being burnt.
- The system requires a startup current of 75A. Please verify that your vehicle's battery can meet this requirement before installation.
- The compressor can only be installed upright with its feet down.
Wiring Diagram and Component Layout
Familiarize yourself with the system's wiring and component layout before beginning installation.
This diagram illustrates the complete system layout, showing connections between the evaporator, compressor, battery, drying bottle, condenser fan, and associated high and low pressure pipes (BH8 and BH13).
This image provides a clear identification of various wires, including drying bottle connecting line, compressor connecting line, general connecting line, fan connecting line, negative pole of power line, power line positive, compressor overheat induction line, and evaporator connecting line.
Installation Steps
Follow these general steps for installation. Refer to the detailed wiring diagrams and consult a professional if unsure.
A visual guide detailing the eight key steps for installing the air conditioning unit, from connecting the compressor to the evaporator, to wiring the control panel and connecting hoses. Ensure all connections are secure and properly sealed.
- Connect the compressor to the evaporator unit.
- Connect the necessary wiring to the evaporator.
- Secure the compressor in its upright position.
- Install the drying bottle and connect it to the system.
- Connect the high and low pressure hoses to the appropriate ports on the compressor and evaporator.
- Install and wire the electronic fan.
- Connect the main power and control wiring to the control panel.
- Ensure all connections are tight and secure, and the system is ready for refrigerant charging (to be done by a professional).
5. Operating Instructions
Controls
The evaporator unit features intuitive controls for adjusting airflow and temperature.
This image shows the control knobs on the evaporator unit. The left knob controls air flow with a 3-position blower switch (0, I, II, III), and the right knob controls temperature with an ON/OFF and TEMP setting.
- Air Flow Control: Use the left knob to select the desired fan speed. Settings typically include Off (0), Low (I), Medium (II), and High (III).
- Temperature Control: Use the right knob to turn the unit ON or OFF and adjust the temperature setting.
6. Maintenance
To ensure optimal performance and longevity of your NEKPOKKA 12V Electric Car Air Conditioning Unit, regular maintenance is recommended:
- Refrigerant Level: Periodically check the R134a refrigerant level. If cooling performance decreases, it may indicate a low refrigerant charge or a leak. This should be serviced by a qualified technician.
- System Cleanliness: Keep the condenser and evaporator coils clean and free from debris to ensure efficient heat exchange.
- Hose and Connection Inspection: Regularly inspect all hoses and connections for any signs of wear, leaks, or damage. Ensure all fittings remain tight.
- Electrical Connections: Check electrical wiring and connections for corrosion or looseness.
7. Troubleshooting
The control panel features an LED indicator that provides diagnostic information through blinking patterns. Refer to the table below for common LED blinking codes and their meanings:
This image provides a guide to the LED blinking patterns on the control panel and their corresponding error or status indications.
| LED Blinking Pattern | Meaning | Action |
|---|---|---|
| Blinking 1 time, pause 1 second | Standby mode | Normal operation status. |
| Blinking 2 times, pause 1 second | Excessive current | Check for short circuits or overloaded components. Ensure battery meets 75A startup current. |
| Blinking 3 times, pause 1 second | Locked rotor protection | Compressor motor is stalled. Check for obstructions or internal compressor issues. Professional service required. |
| Blinking 4 times, pause 1 second | Undervoltage protection | Battery voltage is too low. Recharge or replace battery. Check power connections. |
| Blinking 6 times, pause 1 second | Electric fan fault | Check fan motor and wiring for damage or obstruction. Replace fan if necessary. |
| Blinking 7 times, pause 1 second | Motor lack at phase | Check if the motor got burnt and connection is correct or not. Professional inspection recommended. |
| Blinking 8 times, pause 1 second | Compressor overheated protection | Compressor is overheating. Check refrigerant levels, condenser airflow, and ensure proper ventilation. Allow unit to cool. |
| Blinking 9 times, pause 1 second | Pressure switch protection | Indicates abnormal system pressure (too high or too low). Check refrigerant charge, expansion valve, and system for blockages. Professional service required. |
