According to circumstances, attach the optional external AC fans (JC-AF115R or JC-AF230R) on
the intake vents in the bottom row (see “External AC fan attaching” on page 17).

• Keep enough base stand height not to inhale a coat of dust on a floor from the intake vents.

cover from the top surface of the cube and attach it on the top of the duct. Be sure this work
