Troubleshooting Review the possible solutions below. If the problem persists, please visit www.tripplite.com/support for service. Problem The unit does not function. Cooling performance is unsatisfactory. The unit leaks water. The unit generates excessive noise or vibration. The unit has ice or frost buildup. Possible Cause The unit is turned off. The unit is not plugged in. Main power is off. The air exhaust or intake is blocked. The temperature setting is too high. The fan speed setting is too low. The air filters are dirty. The wattage of the rack enclosure, the size of the room or the ambient temperature exceeds the cooling capacity of a single unit. The drainage plug is not installed. The unit is on an uneven or unstable surface. Possible Solution Turn the unit on. (See "Operation" section.) Plug the unit into a suitable outlet. Check fuses or circuit breaker. Confirm that all ducts and intakes are clear of obstructions. Adjust the temperature setting. Adjust the fan setting. Clean or replace the air filters. Install additional units or contact Tripp Lite for additional cooling solutions suitable for your application. Insert the drainage plug in the drainage outlet. (See "Installation" section.) Move the unit to a level, stable surface. The unit is operating in an environment with excess humidity. OPTION 1: Turn off the unit, and let the unit defrost. Once defrosted, ensure the unit is operating with the fan speed set on HIGH. OPTION 2: Turn off the unit, and let the unit defrost. Once defrosted, operate the unit in DEHUMIDIFY MODE, or increase the desired temperature setpoint. Additional Display Codes Error Codes The Tripp Lite SRCOOL18K and SRCOOL24K has the ability to continually monitor itself. Should an error occur, the display will show one of 5 codes: Error Code E0 E1 E2 E3 E4 Description Internal Communication Error Indoor Temperature Sensor Error Internal Temperature Sensor Error Refrigerant Error Water Full Code E4 can be cleared by emptying the water tank. Consult the Alarm entry in the Operation section for details. For Codes E0, E1, E2, and E3 follow these steps: 1. Power cycle the unit by unplugging it from the source for 5 minutes. 2. Plug the unit back in. 3. Restart the unit. If the code remains clear, continue to operate the unit as normal. If the code returns, please contact Tripp Lite for further instructions. dF Code "dF" will display when the unit detects a condition in which the coil is operating below 33.8° F (1° C) for more than 15 minutes. During a dF code event, the unit's fans will run without the compressor to prevent the evaporator from freezing up. Once the coil temperature is above 33.8° F (1° C), the compressor will resume normal operation. If this condition persists, the unit is operating in an environment that is too cold. Tripp Lite recommends that the unit operate in Dehumidify mode only if operating temperatures are below 68° F (20° C). See Low Temperature Operation in section 6-3 for more information. 12
