11-4 Auxiliary fresh air flange (TCB-FF101URUL)
Installation
1. Using the knockout of the indoor unit main body, as a
marker, cut off the flange with the heat insulator
(styrol) with cutting pliers or cutter.
NOTE
When cutting off the styrol inside, be careful not to insert
the cutter blade deeper than 1.2" (30mm). (Damage to
the drain pan inside can cause water leakage.)
Wear safety globes to carry out these works. Do not
attempt with bare hands.
2. A gap between the styrol and steel plate may cause
a trouble such as condensation. Be sure to attach
the attached heat insulator A first with it aligned to
the screw hole, and then attach B, according to the
right figure.
3. Install the auxiliary fresh air flange to the indoor unit
main body with attached 4 fixing screws.
Duct fan
In order to take fresh air, provide the duct fan
separately.
1. Install the filter for fresh air
2. Provide the check port beneath the duct fan for
maintenance.
3. Connect the duct fan and the indoor unit with inter-
lock wiring.
4. Provide the silencer to prevent the effect of noise.
