Defrost Mode
If the “df” code appears, it means the unit detected an icing problem and has started a defrost
cycle. The compressor will stop and the upper motor will continue to run at high speed for
3.5 minutes.
If the icing problem clears up, the unit will return to normal operation. If the code returns,
check the humidity and temperature of the operating environment. An environment that is too
cool or has excessive humidity can cause icing problems. If the operating environment is normal
and you are still getting the “df” code, contact Tripp Lite for further instructions.
Error Codes
The Tripp Lite SRCOOL2KWM has the ability to continually monitor itself. Should an error occur,
the display will show one of 7 error codes to the left:
Code E4 can be cleared by emptying the water tank. Consult the Alarm entry in the
Operation
section for details.
To clear codes Lo, Hi, E1, E2, E5 and E6, 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.
