Installing The Ventimatic Shutter Assembly - Daikin ARQ Installation Manual

Installing the VentiMatic Shutter
Assembly
The AAF -HermanNelson VentiMatic Shutter Assembly is a one-way
® ®
shutter. It is a continuously variable, gravity-actuated, room exhaust
vent that operates in direct response to positive static pressure, opposing
any airflow into the room resulting in a slight positive pressure.
The VentiMatic Shutter Assembly is mounted on an installed wall louver.
For larger units with 100% ventilation air dampers, two VentiMatic
Shutters may be mounted side by side on the same louver. See figure 27.
The size and appearance of the wall louvers with or without optional
grilles used with the unit ventilator, and the VentiMatic Shutter, are
identical.
When installing VentiMatic Shutter(s) on the wall louver, make sure
all moving parts are free to operate unobstructed and placed level
and plumb for proper operation. If optional steel interior wall grille is
furnished, install as shown in Figure 25.
