Troubleshooting
Review the possible solutions below. If the problem persists, please visit tripplite.com/support for service.
Problem
The unit does not function.
Cooling performance is
unsatisfactory.
The unit leaks water.
The unit has ice or frost buildup.
Additional Display Codes
Display Code Description
df Unit is in Defrost Mode
E1 Indoor Temperature Sensor Error
E2 Internal Temperature Sensor Error
E4 Water Full Error
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 filter is 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 operating in an environment that
is too cool or has excess humidity.
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 SRXCOOL7KRM has the ability to continually monitor itself. Should an error
occur, the display will show one of 3 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.
For Codes E1 and E2 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.
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.

Clean the air filter.
Install additional units or contact Tripp Lite for additional cooling solutions
suitable for your application.
