were removed before.
Rear vented version
All the models with one motor can be
rear vented; if the customer wants to use
this option, it is necessary to remove the
18 screws from the motor group sup-
port. Then take the metal support with
motor included out. Turn the motor to
have the air outlet on the rear side and
fix the scews previously removed.

ting to the fan exhaust point and join up

duct tape. Use duct tape on all joints.

Re-Circulating Requirements.

If the unit is to be used in the recircula-
ting mode, fit the carbon filters after the
installation is complete (refer to Figure
11).
fig. 11
The carbon filter fits in behind the alu-
minium grease filter. Ensure that the
plastic tabs on the carbon filter are fa-
cing outwards otherwise it will be diffi-
cult to remove it later for replacement.
A short length of ductwork must be
connected from the exhaust outlet on
the fan to wherever the air is to be
exhausted.
Allow sufficient space to connect the
ductwork to the top of the exhaust out-
let on the fan housing. Do not fix the
ducting to the range hood exhaust out-
let with screws, use duct tape. Duct tape
should be used on all joints.
