Properly Identify Unit Ventilator(s)

To be sure the correct unit ventilator(s) is/are installed
in the correct location(s), the installer must check the
packing list and unit identification/tagging number(s)
against the plans. Further, the unit data plate, (see
Figure 1 on page 4) located on the lower right end
of the unit ventilator, contains specific information of
standard components as listed in
Figure 4: Shipping Envelope Contents - Located in right
end compartment of unit.
Uncrate and Inspect the Unit
Ventilator(s)
Carefully remove the packaging, remaining alert to any
signs of shipping damage. Be careful not to discard
components that may be included with the packaging.
(You may want to retain some or all of the packaging to
provide jobsite unit location information and temporary
protection for the unit ventilator after installation.) Be
sure to dispose of plastic packaging and protective
cardboard properly, in accordance with local recycling
rules and guidelines.
If unit is damaged, file a claim with the carrier. Notify the
local Daikin Unit Ventilator representative immediately.

Wall Openings, Louvers, and
VentiMatic™ Shutter
Prior to unit installation, be sure that the exterior wall
openings and louvers, as applicable, are ready and in
accordance with the job plans.
Vertical Floor Models AVS, AVV, AVB, AVR are typically
installed in front of a wall opening containing a properly
sized louver that is designed to let in outside air while
preventing water (such as rain) from getting past the
louver and into the unit itself. A weather-tight seal keeps
unwanted air and moisture from entering the occupied
space. See Figure 6 on page 7
page 11, and Table 2 on page 10
details.
VentiMatic™ Shutter Assembly
In many installations, a Daikin VentiMatic Shutter
Assembly is specified. See
shutter is a continuously variable, gravity actuated, room
exhaust vent that operates in direct response to positive
static pressure. It opposes any airflow into the room and
allows a slight positive pressure.
It is important that the VentiMatic shutter and unit
ventilator louvers are mounted on the same wall. This
neutralizes the effect of the wind. Forcing excess
air into the room through the unit ventilator louver
overcomes the same wind pressure that works to keep
the VentiMatic shutter closed. This prevents room air
exhausting from the room through the VentiMatic shutter.
