If the compressor of your Airxcel Air Conditioner doesn't start, first ensure the main power switch is on and the startup interface is displayed. A loose circuit connection could also be the culprit, so tighten the circuit connectors. Finally, the compressor motor might be burned out; inspect the motor for defects and replace it if necessary.
What to do if the external cycling fan on my Airxcel ICE EC06HDNC1U is not running?
If the external cycling fan on your Airxcel Air Conditioner isn't running, it could be because the compressor hasn't started yet, as the outside fan typically runs after the compressor starts. Also, check for any foreign objects blocking the fan blades. Finally, verify that the fan connecting terminal is not loose.
Why is the compressor not working on my Airxcel ICE EC06HDNC1U Air Conditioner?
If the compressor on your Airxcel Air Conditioner isn't working, first check the temperature display inside the cabinet and the compressor output status on the operation interface to ensure there is a cooling demand. Also, consider whether the compressor is within its shutdown delay. In normal operation, the compressor has a minimum shutdown time, and it will not restart until this delay expires, even if the temperature rises to the starting point during this period.
What to do if the internal cycling fan cannot run on my Airxcel ICE EC06HDNC1U Air Conditioner?
If the internal cycling fan of your Airxcel Air Conditioner isn't running, it might be in standby state, which is normal for the first 30 seconds after being powered on, due to automatic control logic. Check if any foreign object is blocking the fan blade. Also, make sure the fan connecting terminal is not loose.
Why is the fan making abnormal noise in my Airxcel ICE EC06HDNC1U?
If the fan in your Airxcel Air Conditioner is making abnormal noise, it could be due to a worn bearing, in which case you should replace the fan. Alternatively, check for any interference between the cable and the fan blades.
What causes the external hydrogen discharge fan to not work on my Airxcel ICE EC06HDNC1U?
If the external hydrogen discharge fan on your Airxcel Air Conditioner isn't working, first check if the operating conditions are satisfied. Verify the external power supply is connected. If the fan is defective, replace it. Finally, ensure that the external fan linkage function is configured.

This document serves as an Installation & Operation Manual for Industrial Climate Engineering's AC Powered Cabinet Climate Control Air Conditioners, specifically models EC06HDNC1U and EC20HDNC1U. It provides comprehensive information on installation, troubleshooting, maintenance, warranty, and application. The manual emphasizes that all operations should be performed by professional engineers and technicians.
The air conditioner's primary function is to cool data centers, outdoor telecom cabinets, and electronic and mechanical equipment shelters (E-Houses). It operates automatically based on the cabinet's internal temperature. A controller compares the cabinet's return air temperature, detected by an internal cycle temperature sensor, with a pre-set point. This comparison dictates whether the compressor or the fan operates.
The unit employs an internal cycle air path that absorbs hot air from the top of the cabinet and discharges cold air from the bottom. Concurrently, an external cycle air path draws in external cold air from the bottom and expels hot air from the top after heat exchange. This design ensures efficient climate control within the cabinet, even when ambient temperatures are low.
The system offers both cooling and heating control modes. In cooling mode, when the cabinet temperature reaches a set point (cooling stop point + sensitivity), the air conditioner increases its cooling output. Cooling ceases when the temperature drops below the cooling set point. For heating, the system activates when the internal cabinet temperature falls below a heating startup point (heating stop point - heating sensitivity) and stops when the temperature rises above the heating stop point. The heating function is optional.
The internal fan operates at a normal speed when the system is running normally. The external fan's speed is regulated by the condenser's temperature in cooling mode, increasing with higher temperatures and decreasing with lower temperatures. In air circulation mode, the external fan stops. The compressor's running speed is also dynamically adjusted based on the temperature difference between the return air and the set value, with higher differences leading to increased compressor speed.
Optional external fans can perform specific functions. A hydrogen exhaust fan can provide automatic cycle hydrogen discharging and forced ventilation, typically with a 24-hour interval and a 5-minute discharge time. Forced ventilation activates when the compressor lacks cooling capacity (due to failure or power loss) and the cabinet temperature exceeds a hydrogen discharging fan startup point by 5°C, and is 3°C higher than the outside temperature. An Emergency Fan (for EC06HDNC1U) starts under similar conditions, specifically when the cabinet temperature is 4°C higher than the outside temperature and exceeds its startup point. An Energy Saving Fan (for EC06HDNC1U) also activates when the cabinet temperature is 4°C higher than the outside temperature and exceeds its startup point.
The unit also features a self-testing function for onsite verification. This diagnostic process involves the indoor fan running for 30 seconds, the compressor and outdoor fan running for 3 minutes, followed by the compressor and outdoor fan stopping while the heater (optional) works for 2 minutes. Finally, the external fan (hydrogen discharging fan, etc.) runs for 2 minutes before stopping, and the unit resumes normal operation logic.
The air conditioner is designed for ease of use and monitoring. It features an intelligent control system and a dry contact and RS485 intelligent communication interface for remote monitoring and parameter adjustment. The unit's controller utilizes a 96x32 LCD with seven buttons for navigation and settings.
The user interface includes ON/OFF, Up, Down, Left, Right, ENTER, and ESC buttons. The ON/OFF button, when long-pressed, toggles the unit's power. The Up and Down buttons are used to select menus/records or adjust setting values (password-protected). The Left and Right buttons facilitate increasing/decreasing setting values or selecting digits during password entry. The ENTER button confirms selections, while ESC returns to the previous menu.
For security, the unit has a factory default operation password ("0001"). Users can change this password through the interface. If no keyboard activity occurs for 60 seconds, the display automatically reverts to the normal display interface. The backlight also turns off after 60 seconds of inactivity to conserve energy.
The unit provides comprehensive alarm information, which can be viewed on the display screen or accessed through the RS485 communication interface. Alarms remain active until the underlying issue is resolved. The system also supports a Door Magnetic Switch Signal (optional on EC20HDNC1U), which triggers an alarm and can stop the unit if the cabinet door is open.
Routine maintenance is crucial for ensuring the air conditioner's normal operation and maximizing its energy efficiency. All maintenance tasks must be performed by qualified professionals, with the power, communication, and alarm output cables disconnected before any work begins.
Key maintenance checks include:
The manual also includes troubleshooting guides for common fan faults and cooling system faults, providing symptoms, possible causes, and recommended remedies. This allows for efficient diagnosis and resolution of issues, contributing to the device's longevity and reliable performance.
