Error Codes
The Tripp Lite SRCOOL12KWT has the ability to continually monitor itself.
Should an error occur, the display will show one of 4 error codes below:
Error Code Description
E1 Indoor Temperature Sensor Error
E2 Internal Temperature Sensor Error
E3 Refrigerant Error
E4 Water Full
Code E4 can be cleared by emptying the water tank. Consult the Alarm entry in the Operation section for details.
For Codes 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 SRCOOL12KWT 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.
Review the possible solutions below. If the problem persists, please visit tripplite.com/support for service.
Problem Possible Cause Possible Solution
The unit does not function. The unit is turned off. Turn the unit on. (See “Operation” section.)
The unit is not plugged in. Plug the unit into a suitable outlet.
Main power is off. Check fuses or circuit breaker.
Cooling performance is unsatisfactory. The air exhaust or intake is blocked. Confirm that all ducts and intakes are clear of obstructions.
The temperature setting is too high. Adjust the temperature setting.
The fan speed setting is too low. Adjust the fan setting.
The air filters are dirty. Clean the air filters.
The wattage of the enclosure, the size of the
room or the ambient temperature exceeds the
cooling capacity of a single unit.
Install additional units or contact Tripp Lite for additional cooling solutions suitable
for your application.
The unit leaks water. The drainage plug is not installed. Insert the drainage plug in the drainage outlet. (See “Installation” section.)
The unit generates excessive noise or
vibration.
The unit is on an uneven or unstable surface. Move the unit to a level, stable surface.
The unit has ice or frost buildup. 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.
Remote Cooling Management
Add remote cooling management to your SRCOOL12KWT with the optional SRCOOLNETLX module. It allows you full remote access for status
monitoring, event notifications and device management on your network. With the SRCOOLNETLX installed, you can:
• Change settings and monitor temperature and humidity from any location
• Receive alerts via web browser, SNMP, SSH, Telnet or command line interfaces
• Access detailed condition and event logs
Learn more about the SRCOOLNETLX at tripplite.com.
