BRANCH DUCT (installation at site)

To discharge air from a branch duct, install it during the initial installation.

1. Branch Duct Installation Procedure

2. Branch Duct Installation

Install branch duct at site by following procedure

(1)Remove insulation along the broken-lines on unit surface at the back-side of the indoor unit. Knock out the branch duct connecting point.

(2)Secure flange, procured locally, by twelve ST screws (4.0 dia).

(3)Connect flange to duct.

(4)Tear off the insulation material on the surface of the main body of the unit, push in the insulation and secure it air tightly.

3.Air flow & Static Pressure Characteristics of Branch Duct
