 key to change the setting to Standby. The cooling unit enters the standby mode.

Electrical Hazard: The Standby option does not remove power from the cooling unit. You 
must disconnect power at the mains to remove power from the cooling unit.

The cooling group configuration options are set during the commissioning of the cooling units in the 
cooling group. 

Caution: This procedure must be performed by APC authorized personnel only. Changing 
the settings incorrectly can cause malfunctions to your cooling unit. 

Use the General menu to set the start-up delay, idle on leak, and refrigerant fill settings.

The delay begins when the cooling unit is started and initialized. The 

cooling unit cannot begin operation until this delay expires. Use the start-up delay to restart equipment 
sequentially after a scheduled downtime or a power outage.

When set to Yes, the cooling unit will enter idle mode if a Water Detection Fault 

activates. Set to No to disable the cooling unit from entering idle mode if a leak is detected. 

Note: The leak sensor (APC part number AP9325) is optional.
Note: There are three alarms that will cause the cooling unit to enter idle mode:

• Water Detection Fault (when Idle On Leak is set to Yes)
• Condensate Pump Fault
• Cooling Failure

See “Alarm messages and suggested actions” on page 29 for more information on alarms.

Set to Start to add refrigerant to the system. This setting turns on the compressor and sets 

the fans to maximum speed until the compressor suction pressure drops below 50 psig for two minutes, 
twenty minutes elapse, or the property setting is changed to Abort.

Caution: The Refrig Fill setting is intended only for charging the unit with refrigerant.
