Important Safety Precautions and Explanation of Symbols ! The exclamation point within an equilateral triangle is intended to alert the user to the presence of important installation, operation, and service instructions in this manual. The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated dangerous voltages within the enclosure that may be of sufficient magnitude to constitute a risk of electrical shock to the user.
The power adapter for the Sherbourn C-12 should be unplugged from the outlet during severe electrical storms, or when unused for a long period of time. The C-12 should only be cleaned as directed in the Installation and Operation Manual. Avoid spraying liquids directly onto the C-12 and NEVER spray liquids into the vents. Care should be taken so that small objects do not fall into the inside of the C-12.

Introduction Thank you for choosing the Sherbourn C-12 Flex-Rack™ Cooling System. Sherbourn’s innovative C-12 Flex-Rack™ Cooling System is an efficient and flexible solution to the problem of excessive heat in a rack or built-in system. Heat is a major threat to the reliability and performance of modern home theater hardware.

Installation and Configuration How the Sherbourn C-12 operates is determined both by switch settings and by mechanical reconfiguration of parts of the device. Read and follow the instructions carefully. Improper or incomplete configuration may result in unusual or unexpected behavior.
Basic Auto operation In this mode the front panel Power switch is set to the Auto position, the Trigger Mode switch is set to the 12VDC position, and nothing is plugged into the Trigger In connector. The C-12 is controlled by the temperature at the temperature sensor. (If the remote sensor is attached, then this is the temperature at that location; if no remote sensor is attached, then it is the temperature at the bottom panel of the C-12 unit.
Mechanical Configuration The direction of air flow in the C-12 is determined by the mechanical configuration of the unit itself. The parts involved in the mechanical configuration of the C-12 are: • Top and bottom plates - The C-12 is always operated with both top and bottom plates in place. The top plate is removed to facilitate installing the foam block or air filter behind the front panel.

Operation The Sherbourn C-12 is normally configured to operate automatically. In normal operation, the C-12 fans will not operate until the configured Starting Temperature has been exceeded (at the sensor). At this point, the C-12’s fans will start operating at minimum speed; fan speed will gradually increase as the temperature rises above the starting temperature.
Periodic Maintenance The Sherbourn C-12 requires very little periodic maintenance. Cleaning the C-12 air filter The interior of the C-12 (and especially the air filter) may become dusty (or accumulate lint and other debris) with normal operation. If this occurs, periodically disconnect the power, remove the top cover, and vacuum out any loose debris and dust that has accumulated (be careful to avoid damaging the interior circuit boards and wiring).
Troubleshooting If problems occur, the first step should be to verify that the Sherbourn C-12 is attached to an appropriate (Sherbourn supplied) AC adapter (“power brick”), and that the AC adapter used is rated for the local AC line voltage. Note: If a cable is connected to the Trigger Input of the C-12, but not connected to a triggering device, the C-12 will not act as expected with the Trigger switch in either position.
