To perform a basic start-up, ensure the unit is properly connected to power, switch the control unit to 'ON', and set the desired temperature. Check that the compressor and fans are operating correctly.
Check the power supply, including fuses and circuit breakers. Inspect the control panel for error codes and reference the manual for specific troubleshooting steps. Ensure all cables and connectors are secure.
Air filters should be inspected every 250 hours of operation and cleaned or replaced as necessary to ensure efficient airflow and cooling performance.
Regular maintenance includes checking refrigerant levels, cleaning heat exchangers and evaporator coils, inspecting belts and pulleys for wear, and ensuring electrical connections are secure.
To reset error codes, power off the unit, wait a few minutes, and then power it back on. If the error persists, consult the troubleshooting section of the manual for further instructions.
Ensure the doors and seals are intact and closed properly. Check the temperature settings and recalibrate if necessary. Inspect the condenser and evaporator coils for any blockages or debris.
Attach a manifold gauge set to the service ports and compare the readings with the recommended pressure values in the manual. Ensure the unit is running at its normal operating conditions for accurate readings.
Excessive noise can be caused by loose components, worn belts, or debris in the fan or motor. Inspect and tighten any loose parts, replace worn belts, and clear any obstructions.
Regularly clean and maintain the unit, ensure proper insulation of the cargo area, and avoid frequent door openings. Set the temperature to the optimal level for your cargo type to prevent unnecessary energy use.
Always disconnect the power supply before performing any maintenance. Use appropriate personal protective equipment (PPE) and follow all safety guidelines in the manual. Ensure the work area is clear of hazards.
