For recirculating installations (FIGURE 3), Charcoal Filters are necessary. Remove all four grease filters and set aside. Attach
one charcoal filter to each end of the blower. Each charcoal filter attaches to the black grid on the side of the blower. Rotate
the filter clockwise to install and counterclockwise to remove (FIGURE 3A). Replace all four grease filters. Some ductwork
must be installed to exhaust the rangehood back into the kitchen, either at the top of the cabinet or at the face of the soffit. A
plastic vent grate (FIGURE 3B) supplied with the rangehood can be used to cover the duct opening. This duct work must not
terminate into a dead air space.

The Cristal HC slideout rangehood is designed to offer wide flexibility of installations.
The rangehood can be ducted vertically or horizontally through a 6" round vent.
The unit can also be installed in a recirculating configuration. The unit comes
standard in the top venting position. FIGURES 1 and 2 show vertical and horizontal
installations for this unit. FIGURE 3 shows recirculating installation.
The Cristal HC requires 6" round ductwork. To ensure that the blower performs to
its highest possible capacity, ductwork should be as short and straight as possilbe.
For satisfactory performance the duct run should
not exceed 50 equivalent feet if ducted using the
required minimum 6" round duct. The equivalent
feet in FIGURE A for each piece of duct in the
system An example is given in FIGURE B. For
best results, use no more than three 90°
elbows. Make sure that there is a minimum of
24" of straight duct between elbows if more
than one is used. Do not install two elbows
together. If you must elbow right away, do it
as far away from the hood's exhaust opening
as possible.

PLAN THE DUCTWORK
For direct rear venting (FIGURE 2), you must
change the blower position. Remove the 12
screws that hold the metal housing to the
HORIZONTAL
rangehood body. Remove the 4 screws that
DUCTING
hold the blower housing to the metal housing.
Rotate the blower 90 degrees toward the back
and then flip it over 180 degrees. Be sure that
the power supply cable is properly positioned.
Replace all screws, making sure that they are
firmly fastened.
