S313 Manual Mode—Places the Liebert iCOM in manual mode. This is the initial setting necessary 
to activate any of the following items.
Manual Mode is used a diagnostic tool to test components and operation of the unit. This is useful 
when testing components such as fans, LLSV, compressors and actuators to validate operation and 
performance. To use manual mode, enter the Level 2 password, 5010, and select YES on line S313. 
With the exception of compressor evacuate mode, Manual Mode will time out after 30 minutes of 
inactivity. When finished running components in manual mode, change line S313 back to No. All the 
corresponding components changed with Manual Mode enabled will go back to normal. The unit will 
resume operation as it was before Manual Mode was enabled. Safety routines, such as overload 
alarms, high-pressure lockout, etc., will prevent some features from being used. If an alarm has been 
disabled but is active, some Manual Mode functions will not work.
S314 Motor(s)—Starts the unit’s main fan. The main fan must be On before any of the following 
overrides can be activated. Compressor evacuate mode does not require motor(s). 
S315 Compressor 1—Turns on Compressor 1 and selects the mode of compressor operation. The 
choices are RUN, EVACUATE and CHARGE. To access each mode, press the Enter key while 
highlighted on S315. Press the Right arrow key to advance to the left. The compressor mode may be 
changed by pressing the Up or Down arrow key. Once the desired mode is shown, press the Enter key. 
The compressor state to the far right must be placed to On if run or charge modes have been selected. 
No further action is required for evacuate mode.
• Run: This function allows the compressor to run at any given capacity. The compressor capacity 
can be adjusted on line S317.
• Evacuate: This function allows all solenoid valves in the refrigerant circuit to open while the 
compressor remains in Off. This mode is can be used for either leak checking or evacuation. This 
mode does not have a timeout period.
• Charge Mode: This function allows the compressor to run at 100% loaded capacity for 30 minutes 
at a time. The suction pressure must be at least 15 psi or the compressor will be stopped.
S316 Compressor 1 Capacity—Enables Compressor 1 Cycle Ramp.
S317 Compressor 1 Cycle Ramp—Selects the capacity the compressor should run at. The range is 
20 to 100%.
S318 Compressor 1 LLSV—Shows the status of the liquid line solenoid valve for Compressor 1.
S319 Compressor 2—Turns on Compressor 2 and selects the mode of compressor operation. The 
choices are RUN, EVACUATE and CHARGE.
S320 Compressor 2 Capacity—Enables Compressor 2 Cycle Ramp.
S321 Compressor 2 Cycle Ramp—Selects the capacity the compressor should run at. The range is 
20 to 100%.
S322 Compressor 2 LLSV—Shows the status of the liquid line solenoid valve for Compressor 2.
