5. Operation

Caution: Before attempting to operate the SRCOOL33K/SRXCOOL33K, ensure that it has been properly installed in accordance
with the Installation Manual, including stabilization and sufficient clearance around the unit.
Tip Warning! If the unit has been tilted more than 15° during shipping, unpacking or installation, allow unit to
stand for 24 hours before turning on. Do not operate if there is visible internal or external damage.
5.1 Cooling Methods
The main function of the SRCOOL33K/SRXCOOL33K is to remove waste heat and return treated air to the room at the required temperature.
The specific cooling method used is determined by the configuration of the rack enclosures in the room. The unit continuously varies the
cooling output to maintain a set temperature at the return of the unit. The cooling output is varied by constantly adjusting the speed of the
fans and the compressor. If desired, the fan speed may be set to a constant value by the user. Note: Setting a lower fan speed may limit the
unit's capacity.
The unit uses the setpoint entered by the user to control the fan speed. This variable should be set based on the installation configuration.
Configurations
Room Cooling Mode: When the unit is installed stand-alone in a server room acting as a CRAC unit, the setpoint should be set to the
desired room temperature.
In-Row/Hotspot Mode: When the unit is installed in a hot aisle/cold aisle configuration, the setpoint should be set to the desired cold aisle
temperature plus the expected temperature rise across the problem rack (~10°C; 50°F).
