Receiving & Handling
This product was carefully packed and thoroughly
inspected before leaving the factory. Responsibility
for its safe delivery was assumed by the carrier upon
acceptance of the shipment. Claims for loss or damage
sustained in transit must therefore be made upon the
carrier, as follows:
Visible Loss or Damage
Any external evidence of loss or damage must be noted
on the freight bill or carrier’s receipt, and signed by the
carrier’s agent. Failure to adequately describe such
external evidence of loss or damage may result in the
carrier’s refusing to honor a damage claim. The form
required to le such a claim will be supplied by the carrier.
Concealed Loss or Damage
Concealed loss or damage means loss or damage which
does not become apparent until the product has been
unpacked. The contents may be damaged in transit due
to rough handling even though the carton may not show
external damages. When the damage is discovered
upon unpacking, make a written request for inspection
by the carrier’s agent within fteen (15) days of the
delivery date. File a claim with the carrier since such
damage is the carrier’s responsibility.
Storage
If equipment is stored for any length of time before
installation, it should remain in its shipping packaging in
a clean, dry, climate controlled area.

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 identication/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 specic information of
standard components as listed in Table 1.
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, le 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 through Figure 21 on
page 11, and Table 2 on page 10 for various louver
details.
VentiMatic™ Shutter Assembly
In many installations, a Daikin VentiMatic Shutter
Assembly is specied. See Figure 5. This one-way
shutter is a continuously variable, gravity actuated, room
exhaust vent that operates in direct response to positive
static pressure. It opposes any airow 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.

Typical Installation Methods
If the fresh air opening has not yet been made, see Figure
9 on page 8 through Figure 16 for the recommended
locations and the job-specic plans for the exact location.
Follow local codes.
Cut the wall opening so that it is slightly larger than the
louver being installed. For dimensions, see Table 2. If
the opening is already there, measure to be sure there is
a minimum of 3/8ʺ (9mm) clearance around all sides. For
masonry installations, a lintel must be installed above all
louvers.
In thick wall applications, the portion of the wall
between the louver and the unit is the outside air
plenum. Line this plenum area with 3/8ʺ (9 mm) mortar
or other suitable material. In some applications, the
job specications require a metal sleeve connection
between the louver and the unit. If using such a sleeve,
properly caulk it to ensure a weather-tight seal. This
is critical in preventing freeze-ups, cold drafts, and air
inltration. Be sure the wall is smooth, square, and
provides a suitable mating surface.

Before setting the louver, construct a sloping, sealed
cement mortar base to drain unwanted moisture to the
outside, (see Figure 17). Be sure the mortar base is 1ʺ
(25mm) thick at the unit and tapers toward the louver.
The mortar at the unit also acts as a backing against
which the open cell gasket of the unit itself can seal.
This is critical in preventing water leaks and air leaks
under the unit. Be sure the sealed cement mortar base is
smooth and ush with the interior wall.
If it is not possible to construct a sloping mortar base,
then eld-supplied ashing is required. See Figure 18.
The ashing should terminate ush with the exterior of
the building. Place a bead of caulk under the ashing to
prevent moisture from wicking back to the unit. Do not
caulk the joint between the louver and the ashing. This
joint is designed to let unwanted moisture escape.

CAUTION
Personal injury hazard. Wear protective gloves to avoid possible cuts
and abrasions from exposed edges.Avoid contact with sharp edges.
See Figure 6 on page 7 through Figure 21 on page
11. Before setting the louver, be sure the drain lip
(vertical louver) are at the bottom, horizontal louver
blades face down and the bird screen is towards the
unit. See Figure 20 and Figure 21 on page 11. Place
a heavy bead of caulk along the top and the two vertical
sides of the louver, leaving the bottom uncaulked so that
if moisture gets into the area between the louver and the
unit, it can drain to the outside, unrestricted.
If the louver is supplied with anges, (Figure 20) place
an additional bead of caulk on the inside of the top and
side anges that come in contact with the building facade.
Do not caulk the bottom ange. Place the louver in the
opening and push it tight against the supplied building,

www.DaikinApplied.com 11 IM 817-7
fastening it to the exterior of the building using fasteners
(by others) appropriate to the installation. Seal the top and
sides with a waterproof caulk to make it weather-tight. Do
not caulk the bottom of the louver; doing so might trap
unwanted moisture behind the ange.
If the louver is supplied with no anges, (Figure 21)
place the louver in the opening so that it is recessed a
minimum 1/16" (2mm) beyond the building facade or
as directed in the architectural plans. If specied in the
plans, secure the louver in the wall using mechanical
fasteners (supplied by others) appropriate to the
installation. (See Figure 19 for suggested fastening).
With the louver solidly in place, run a bead of caulk
around the perimeter of the louver to seal it weather-
tight. Do not plug the weep holes (horizontal louver) or
the drip line (vertical louver). This might restrict the ow
of unwanted moisture to the outside.
See Figure 18 on page 10, if ashing was used
instead of the sloping mortar base. Caulk the ashing
where it meets the inside of the opening between the
louver and the unit. This helps prevent moisture from
getting under the ashing and into the room.

mounted side by side on the same louver, see Figure 24
on page 12.
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 22.

Before Setting the Unit in Place
Move the unit ventilator to the correct location. See Table
1 on page 6 for approximate shipping weights.
Carefully remove unit ventilator from wood skid. Be sure
to properly dispose of the skid in accordance with local
recycling rules and guidelines.
Removing Unit from the Skid
Remove fasteners at each end which hold the unit to the
skid and carefully slide the front of the unit off the skid
(1). Tip unit forward until the bottom of the slotted front
kickplate is resting on the oor (2). Lift rear of unit off of
the skid by tipping unit forward while supporting the unit
from the front, until it is possible to slide skid out from
under the unit. GENTLY LOWER the rear of the unit to
the oor (3).
Figure 25: Removing Unit from Skid
1. Carefully slide the front of the unit off the front of the skid.
Approx. 10"
2. While supporting unit from the front, slowly tip unit forward
until bottom of kickplate is resting on oor. Lift skid slightly
and GENTLY lower the rear of the unit to the oor while
pulling skid back (DO NOT LET THE UNIT DROP).
Tip forward until
kickplate rests on floor
Kickplate
Leakage of outdoor air wastes energy, causes drafts and erratic
unit ventilator operation. Check the following details:At the correct
unit ventilator location, examine the wall surface. Make sure that
it is smooth, plumb, and perpendicular to the oor. The seals on
the rear of the unit ventilator will take up the small irregularities
found in normal masonry construction. If the wall is irregular
or has mullions, install furring strips to provide a ush surface
against which the unit ventilator can seal. If there are moldings
on the oor/wall line, omit them behind the unit ventilator. Provide
a sealing surface at the oor line. Install a seal pad under the
unit to prevent air leakage. Install the unit ventilator against a
wall made of non-combustible material, and on a oor made of
non-combustible material. Floor must be level, unbroken and
structurally strong to support the unit.

DANGER
Personal injury hazard. Wear protective gloves to avoid possible
cuts and abrasions from exposed edges. Avoid contact with
sharp edges.
CAUTION
Procedure
If the unit has a cooling coil, check the condensate drain
pan to be sure it slopes down toward the drain stub-up
end. To do so, compare the right and left hand drain pan
ends to Figure 30 & Figure 31 on page 14. The end
with the shallow lower bracket (Figure 30 on page 14)
is the low end of the drain pan. To reverse the slope of
the drain pan do the following:
1. Remove the lower bracket and upper plate from each
end of the unit, as shown in Figure 30 and Figure 31
on page 14. This is done by removing the screws
in each with a 1/4 inch nut driver.
2. Reinstall the brackets on the opposite end of the unit.
The drain pan has two (2) connections on each end; a standard
drain connection and an overow connection.
NOTICE
3. Verify the standard drain connection is open on the
low (drain) end only. If the drain connection stub-outs
at the high end of the drain pan are open, seal them
water tight with silicone sealer or similar.
4. Mount static equalizer cover to low end bracket of
drain pan.

Unit Ventilator Installation
Before setting the unit ventilator in position, be sure that
eld-supplied electrical connections are in place, de-
energized and in accordance with the plans.
Move the unit ventilator into position against the wall
surface. Check to see that the unit ventilator is level
from end to end and back to front. Using a 4' level is
recommended. Leveling bolts are located at each end of
the front kickplate (Figure 34).
Figure 34: Leveling Legs Location
NOTICE
Face and Bypass damper set-up is required at start-up.
Failure to properly set-up Face and Bypass damper can result in
control problems and unit damage not covered by warranty. Refer
to Service Bulletin, UV-SB-106507312.
Figure 35: Setting The Unit Ventilator In Place
Remove
moldings
behind unit
Refer to Figure 32 on page 15 and Figure 26 and Figure
27 on page 13 and attach the unit ventilator to the wall
through the four (4) mounting holes provided, using eld-
supplied fasteners appropriate to the wall construction and
the washers provided in the brown envelope with these
instructions (Figure 36). Envelope also contains allen
wrench to provide access to unit. Push the unit ventilator
tight to the wall structure so that the outdoor air seals are
compressed. Secure the wall fasteners to prevent the unit
ventilator from moving and tipping over.
Figure 36: Shipping Envelope Contents.
Make Piping Connections
CAUTION
Be sure the hot and chilled water supply and return system are
thoroughly ushed and cleaned before connecting piping to the
unit ventilator. Debris in the lines can damage the unit.
For All Systems
Be sure to install the control valve(s) on the correct unit
ventilator. Indiscriminate mixing of valves in the eld can
result in valves improperly sized for the desired ow rate,
which can result in poor operation and coil freezeups.
Install control valve so there is at least 2ʺ (51mm) minimum
clearance to remove the actuator from the valve body.
Be certain that the control valve is installed correctly,
with its orientation vertical. Valves should be installed at
least 5 degrees off center.
CAUTION
Be certain that the control valves are installed with the proper
port orientation to provide proper ow and fail safe operation.
Incorrect installation can result in improper unit operation, and/or
the possibility of coil freeze-up.
With future servicing considerations in mind, use
standard, eld-supplied shutoff valves and union
connections; this permits easy removal of the coil or
control valve if servicing is required.
WARNING
While brazing, have an extinguisher readily available. Wear
appropriate eye and hand protection. Ensure all areas with shared
ventilation have ample fresh air ventilation.
Proper ventilation is required for brazing. When brazing,
be sure to protect unit ventilator components from
overheating damage (melting insulation, also damage to
valves, wiring, electronics, sensors, etc.).
Before lling, be sure to ush all piping adequately so that
all debris is removed. Debris can prevent proper valve
operation, resulting in overheating, overcooling, etc.

www.DaikinApplied.com 17 IM 817-7
Ensure proper insulation of supply and return piping.
Proper insulation prevents loss of unit ventilator capacity,
overheating of end compartment, and / or moisture
dripping.
The piping to and from the unit must be protected from
outside air and freeze conditions. The piping must be
suitably insulated for condensation or heat lose or gain.
Penetrations entering the unit end compartments must
be tted/sealed for unit integrity.
Water Coil Connections
Hook up water piping in accordance with Figure 37
and Figure 38 for hot water and chilled water coil
connections.
CAUTION
Failure to install water piping to coils properly can result in
improper unit operation and coil freeze-ups.
NOTICE
Use piping shut off valves and connection unions for future
servicing to the coil supply and return stubs, instead of hard
piping. This permits easy removal of the coil or control valve if
servicing is required.

2-pipe Chilled Water/Hot Water Systems
After making the piping connections, securely attach and
insulate the water-in temperature sensor (OCT) to the
water coil supply line. The sensor should be located on
the water supply line in an area where there is continuous
water ow. The sensor hangs loose in the same end
compartment as the coil connections. This sensor must
be attached correctly for proper unit operation.
After Brazing
Install provided donut shaped insulation seals around
pipe ttings, by removing white backing. Press seals up
to coil partition to seal gaps in partition insulation.
CAUTION
Donut insulation seals must be installed for proper air ow through
the coil.
For Water Systems
After ushing piping adequately, so all debris is removed,
ll the system.
WARNING
Water system under pressure. Keep face and body parts well
away from vent. Unscrew the vent plug only one or two complete
turns, and vent slowly. Water pressure can result in severe
personal injury.
At initial operation, vent manually by unscrewing the vent
plug one or two turns, Figure 40. After venting, tighten
the vent plug rmly.
