TO INSTALL, FOLLOW THE STEPS AS FOLLOWING:
INSTALLATION
MAINTENANCE
1. PREPARATION FOR
INSTALLATION (Figure 2)
The unit should be ceiling insert
only. The size of joists should be at
least 2" wide and 4" high. The
space between two joists should
be 16". From the above surface of
the suspended ceiling there should
be minimum 9" distance to the
roof.
2. INSTALLATION
1) Remove the grill by a little press
the spring inside and take off the
fascia from the housing (Figure 3).
2) Remove the wire box cover from
the housing and install the 3
brackets onto the housing in the
very positions (Figure 3).
3)Position housing between joists
and extend mounting brackets.
Mark the top of keyhole for screws
on all mounting brackets. When
fixing the brackets onto ceiling
joists, make sure to reserve the
suspended ceiling thickness
between bottom edge of housing
and ceiling joists. After the final
ceiling work, the bottom edge of
housing should be flush with
suspended ceiling (Figure 4).
Note: Make sure the distance from
the fan outlet to the wall must be
less than the length of the ventiduct
before installing.

5) Hang housing onto the screw and
pound all the screws tight. Connect the
end of wire in the wire box with power
wire outside according to the wire diag-
ram, then replace the wire box cover
after putting the protective tube
for the power wire in the very position.
Fix the ventiduct tightly onto the fan
outlet (Figure 6).
Note: To be most effective, please keep the ventiduct as straight as possible.
6) Replace the grill after finishing the ceiling (Install the light if has).
1. Shut off power before servicing or cleaning.
2. Remove the grill. Soft brush and clean water can be used for cleaning the grill. For the dirt
that cannot be wiped off easily, you may immerse it into the neutral detergent first.
