1. PREPARATION
WARNING
• If the range hood is not installed properly, it could become detached and fall off.
• Ensure that the metal duct does not touch other metal housing materials,
otherwise fire or electric shock could result.
1 This range hood can discharge upward
or backward. According to the conditions
where the hood is installed, determine
whether it will discharge vertically or
horizontally (3¼"
× 10" duct). For vertical
or horizontal discharge, run duct work
between the hood location and a roof
cap or wall cap.
For the best results in either directions,
use a minimum number of transitions
and elbows. Be sure to attach a roof cap
or wall cap to avoid leaking rain in the
end.
2 The range hood unit must be mounted to a liner which has the following
dimensions. Install the liner securely after checking that the opening size of the
liner is the same as the figure below.
INSTALLATION
CAUTION
The liner should be installed tightly. If the liner installation is not correct, the range
hood unit may become detached and fall off.
