Instalation Of Diffuser And Inlet Grille - Lennox CWC 090-4P Installation, Operation & Maintenance Manual

INSTALATION OF DIFFUSER AND INLET GRILLE

MOUNTING THE DIFFUSER PANEL TO THE UNIT
Check that the position in which the diffuser is mounted is the right one.
1. - Release the air intake grille.
2. - The diffuser panel can then be provisionally positioned on the cassette using the fixing clips.
3. - The diffuser is fastened with the eight bolts supplied.
4. - Make sure that the frame has not been deformed in the installation, by an excessive tighten of the bolts. There
must be no recirculation of air between intake and outlet air paths.
The diffuser panel is sealed with insulation to avoid air
gaps between the unit and the air panel. The insulation
can be compressed from 8 mm to 3 mm, allowing the panel
to be tightened to the cassette by up to 5 mm.
WARNING
Electric shock hazard can cause injury or death. Before
attempting to perform any service or maintenance on the
unit, turn OFF the electrical power, and check that the fan
has stopped.
