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 Description
E0 Internal Communication Error
E1 Indoor Temperature Sensor Error
E2 Internal Temperature Sensor Error
E3 Refrigerant Error
E4 Water Full
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
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.
The unit is operating in an environment with excess humidity.
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.
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.
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.
