Dual-cool Installation Instructions
The Active Thermal Management Dual-cool is a self-contained ventilating system designed to
cool audio-video installations in closets or cabinets, whether the equipment is on shelves or in
racks.
Rack-mounted systems
To save valuable space on the front rails of the rack, Dual-cool can be mounted to the rack’s rear
rails. It will protrude into the rack only 7”, allowing it to be located behind equipment that does
not extend the full depth of the rack. It should be located near the top of the rack so that heat
sources are below it.
Shelf-mounted systems
Fasten the (optional) wall mount bracket securely 12” to 18” above the top shelf. The mounting
holes are spaced 16” apart; fasten it securely into wall studs. Using the screws provide, fasten the
Dual-cool to the bracket as shown.
All installations
Connect the tubing supplied with the Dual-cool to its exhaust port and run it to the area where the
hot air is to be exhausted. Use the backflow blocker (supplied) to hold the tubing against the wall
or ceiling into which a 4” hole has been made for air flow as shown. Attach the backflow
blocker to the wall or ceiling first, making certain that the movable disc is positioned to prevent
air from flowing towards the Dual-cool, then connect the tubing to the backflow blocker.
After mounting the Dual-cool, connect the output lead from the power supply to the power input
jack on the side of the Dual-cool’s chassis, and plug the power supply into an AC outlet.
Plug the thermal probe into its connector on the Dual-cool’s chassis. If the probe is in an
environment below about 90 degrees, the fans should not run.
