6 Drainage Plug Insertion

Warning: The unit's built-in re-evaporator will not function until you insert the drainage plug into the drainage outlet.

When the unit cools or dehumidifies, condensation forms. The unit has a built-in re-evaporator that allows it to expel condensation through the warm air exhaust stream. This feature allows the unit to operate indefinitely without requiring you to empty a water collection tank. The unit ships with both the upper and lower drainage plugs pre-installed.

6-1 Cooling Mode with Re-Evaporation

This is the default mode of operation.

Note: Both drainage plugs must remain installed to enable re-evaporation of condensation.

Diagram of a server rack with heat exchangers and a cable, labeled '6-1' (no text or symbols on the diagram itself)

6-2 Cooling Mode without Re-Evaporation

Use this mode in high humidity environments when the unit's capacity to evaporate condensation exceeds the amount of condensation produced. Also use this mode during shut downs when the "Water (Tank) Full" error frequently occurs (see Troubleshooting section for more information on error codes).

1 Remove the rear panel by lifting it up by its sides to disengage from the unit, then pulling away to detach. Remove the top and bottom drainage plugs.
2 Route two user-supplied 3/4 inch or 18 mm drain lines A through the rear panel's top and bottom holes B, and attach to each of the unit's evaporator drainage outlets C, and route the open ends of the drain lines to external drainage.
3 To reattach the rear panel, align the panel hooks D with the unit's slots E, push in to engage, then push down to secure the panel to the unit.

Low Temperature Operation

The SRCOOL18K/SRCOOL24K is a high performance cooler capable of producing very cold air output. When using the SRCOOL18K/SRCOOL24K in environments that are already cold (68°F / 20°C or less), Tripp Lite recommends using the Dehumidify Mode only. This will allow the unit to continue to provide supplemental cooling while preventing any evaporator icing issues caused by the low room temperature.

Operation

Warning: Install the unit according to the instructions in the "Installation" section before attempting to operate it.

Power

Turn the unit on or off by pressing the "POWER" button.

The unit has a three-minute compressor delay in order to prevent potential circuit overloads at start up.

Automatic Restart Feature

The unit will turn on and resume operation automatically when power is restored after a power outage. The unit will use the same settings that it used immediately before the power outage occurred. Note: If the power outage is brief, the unit will run the fan alone for three minutes before resuming normal operation. The delay allows the compressor to depressurize so the unit will function properly when it enters Cool mode.

Cool Mode

Pressing the "FUNCTION" button cycles between Cool mode and Dehumidify mode. The "COOLING" LED illuminates when Cool mode is active.

Press the TEMP+ and TEMP- buttons to set the temperature in Cool mode. The selected temperature is shown on the numeric display. Once set, the desired temperature will blink five times after which the display will show the current room temperature.

Press the “FAN SPEED” button to cycle between high, medium and low fan speeds. An LED illuminates to indicate the selected fan speed. When speed is set on AUTO, the unit will automatically select a fan speed based on the set and ambient temperatures. If ambient temperature is lower than the set temperature, the fan will run and the “COOLING” LED will blink to indicate that the compressor is off. When cooling resumes, the “COOLING” LED will remain illuminated.

FUNCTION COOLING TEMP+ TEMP- 88 SPEED HI MID LOW AUTO

Dehumidify Mode

Pressing the "FUNCTION" button cycles between Cool mode and Dehumidify mode.

The “DEHUMIDIFY” LED illuminates when Dehumidify mode is active. In Dehumidify mode, the fan runs at a fixed speed and temperature controls are irrelevant. For optimal performance in Dehumidify mode, close windows and doors, remove the top drain plug and route user-supplied drain line to external drainage.

Timer

The "TIMER" button allows you to schedule the unit to turn on or off automatically.

Timer On (Note: The unit must be off to activate the Timer On function. Confirm that mode, temperature and fan speed settings are correct before activating the Timer On function.) Activate the timer by pressing the "TIMER" button. Press the TEMP+ and TEMP- buttons to set the delay (in hours) before the unit will turn on. The number of hours is shown on the numeric display. The number will flash on the screen five times before returning to the current temperature.

Timer Off (Note: The unit must be on to activate the Timer Off function.) Activate the timer by pressing the "TIMER" button. Press the TEMP+ and TEMP- buttons to set the delay (in hours) before the unit will turn off. The number of hours is shown on the numeric display. The number will flash on the screen five times before returning to the current temperature.

TIMER TEMP+ TEMP- 88

Quiet Control Mode

The unit includes a Quiet Control mode which regulates the cooling via the timer and microprocessor to achieve quieter operation levels when noise is an issue.

To activate, press the "QUIET" button. The Quiet LED will turn on. Set the desired temperature and then set the timer to the duration of the Quiet Control mode cycle. During the course of the cycle, the microprocessor memory will adjust the preset temperature by 0.9^ (0.5^) every 30 minutes until it reaches the desired temperature. Once the temperature is reached, the unit will maintain the temperature for the duration of the set time.

QUIET QUIET TIMER TEMP+ TEMP- 88

Changing Degree Units

The unit can display temperature in both Celsius and Fahrenheit. The default setting is Fahrenheit.

To toggle between temperature modes, put the unit in standby mode. The air conditioner is in standby mode when it is plugged into live AC power, but powered off. Then, hold the "FUNCTION" key for 10 seconds. To verify the degree units have changed, power on the unit.

Operation (continued)

Alarm

When the water tank is full, the unit will display the message "E4" on its screen. To resume normal function, turn the unit off, remove the drainage plug and drain the excess water from the unit. Replace the plug and turn the unit on to begin cooling.

O ALARM

Maintenance

Periodic maintenance extends the unit's lifespan and permits maximum operating efficiency.

Replacing the Air Filters

The SRCOOL18K and SRCOOL24K use replaceable air filters available for purchase at your local hardware or home improvement store (two per front and rear panel, see below for filter dimensions). It is important to keep the air filters clean and free of dust. When the filters are dirty or clogged with dust, it decreases cooling efficiency and can threaten air quality. Tripp Lite recommends cleaning the filters at least once every two weeks.

Filter Replacement (Front and Rear Panels)

1 Remove the panel by lifting it up by its sides to disengage from the unit, then pulling away to detach.
2 On the inside of the front panel, replace both of the used filters with two new filters A (see table below for filter dimensions).

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

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^ (1^) , 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 16-3 for more information.
