Hardware Description & Installation Manual
Ensure that the front panel ventilation slots are not obstructed. Check the air filter regularly
to ensure that it is not plugged up with debris. The filter may be cleaned by rinsing in warm
water. Dry thoroughly before replacing it in the frame. See
page 53, for details.
Densité 3+ FR1 fan speed control
On the Densité 3+ FR1 frame’s
rear panel, a slider switch
beside the controller-side fan
allows the speed of the two
rear-panel fans to be specified
by the user. Two settings are
provided:
• FULL – The fans operate at
top speed at all times.
• VAR – The fan speed is
managed by the controller
card, which is monitoring
the temperature inside the
frame. This is the factory-
default setting, and it is appropriate for most situations.
Use a small tool (e.g., a pen tip or a small screwdriver) to change the switch setting.
