Mounting instructions
Wall-hole construction
1.Determinetheinstallationposition.
1) Make sure to allow the required clearances (at
least64mmontop,83mmtoleftandright,
and113mmonbottom)aroundthemounting
plate, as shown in the drawing below.
* Nothing should obstruct the
frontoftheunit.(Donotplace
anythingblockingairowinfront
oftheLossnay.)
2)Checkthatthereinforcement(insidewall)is
positioned properly to secure the mounting
plate.(Ifthereisnoreinforcement,buildina
supporting structure.)
3) Place the mounting plate on the wall.
4) Attach the mounting plate loosely (with single
wood screw).
Note
-Make sure that the mounting surface of the
mounting plate is at.
- Ifitisnot,Lossnayoperationcouldgenerate
noise or the shutter could not operate
properly.
2. Determinethepositionofthewallholes.
Positionthewallholesawayfromobstructions
in the wall, within the ranges shown in the
mounting position diagram on page 3.

3. Drill the wall holes.
1) Removethelooselyfastenedmountingplate.
(Leavethewoodscrewlooselyfastenedin
procedure1inplace.)
2)Drillthewallholesofø85toø90mm.
Note
-Make the holes so they slope down as they
exit the outside wall.
- Thisisnecessarytopreventtheinltrationof
rainwater.
4. Pull out the power and connection
cables.
For VL-100EU5-E only
1)Determinethepowerandconnectioncable
pull-outlocationandmakeahole.(Seethe
mounting position diagram on page 3.)
2) Pull out the power and connection cables on
the indoor side.
Note
-For VL-100U5-E, install an electrical outlet
somewhere that the power cord plug can
reach. (The cord has an effective length of 3
m.)

Note
-Check that each air supply/exhaust pipe
A catches on all four prongs of its pipe
mounting plate. (If a prong has not caught,
the pipe will press against the back of
the Lossnay unit and the shutter may not
operate properly.)
4)Ifthewallismorethan300mmthick
Cutairsupply/exhaustpipesBinkeepingwith
thecuttingdimensionsofstep2(wallthickness
+30to40mm).
Note
-Securely screw air supply/exhaust pipes A
and B together all the way.(If they are not
screwed together tightly, water inltration
may occur.)
-Caulk the connections between air supply/
exhaust pipes A and B as shown above.
Attaching the mounting plate
1)Attachthemountingplatetothewall
provisionally using a single loosely attached
screw.
2) Hang a plumb bob to make sure that the
looselyattachedmountingplateishorizontal
(towithin1°).
3) Attach eight wood screws at locations where
thewallcontainsreinforcingmaterial.
Note
-Attach the two locations near the catches
underneath the catches.(See diagram above.)
-To attach the plate to a concrete wall, use off-
the-shelf concrete screws.

Cutting air supply/exhaust pipes
1)Measurethewallthickness.
(Ifthewallismorethan300mmthick,use
theprovidedairsupply/exhaustpipeB).(See
page4,section4,formountinginstructions.)
2) Cut air supply/exhaust pipes A perpendicular
to the pipe axis at the length shown in the
gureabove.
- Ifthepipeislongerthanitisshown,the
weathercoverwillnott.
3) Prepare the air supply/exhaust pipes.
-Insert each air supply/exhaust pipe A
into a pipe mounting plate and rotate it
counterclockwiseuntilthefourprongscatch.
Caution
-Mount air supply/exhaust pipes A so that
the UNDER mark is at the bottom. After
mounting the pipes, check that they slope
downward as they go outside. (If they do
not, rainwater may inltrate the wall and the
shutter may not operate properly.)

2. Installing the weather covers
1)Inserttheweathercovermountingplatesinto
the air supply/exhaust pipes.
2)Tightentheangenuts.(Besurethat
theUPPERmarksontheweathercover
mounting plates are at the top.)
3) Attach the weather covers with the mounting
screws.
Note
-The weather covers are blocked in one area
to ensure that the air supply and exhaust do
not mix. Mount the blocked parts on both
the air supply and exhaust sides so that
they are on the left, as shown above.
-If the weather covers shift, check that the
air supply/exhaust pipes are cut to the
correct dimensions. (Pushing the pipes too
hard into the wall may cause the pipes to
shift or prevent the shutter from operating
properly.)
-Weather cover mounting plate have two
holes (φ5 mm) in them. Use these holes to
secure the anges to the wall.

Test run
■ Do the test run with the customer present, if at all possible.
1.Turnthepoweron.
1)Turnthecircuitbreakeronatthedistributionboard.
2)Insertthepowerplugintothewalloutlet.(VL-100U5-Eonly)
2. Check the operating modes.
ConsulttheOperatingInstructionsforoperatinginstructions.
Slide the shutter knob to the open position.
3.Checkthatthereisnoabnormalvibrationornoise.Afterconrmingthis,stoptheunit.
1)Whenstopped,movetheshuttertotheclosedposition.(Thisensuresthatnodustwillgetintothe
unit prior to its use by the customer.)
2)Removethepowerplugfromthewalloutlet.(VL-100U5-Eonly)
3)Turnthecircuitbreakeroffatthedistributionboard.
To be explained to the customer
-Show the customer the location of the distribution board circuit breaker and the electrical outlet
or wall switch.
-Tell the customer the results of the checklist.
-Give the customer the "Installation Manual", as well as the separate "Operating Instructions".
-If the customer is not present, explain these items to the ordering party (such as the owner) or
manager.
Checks after mounting
■Aftermountingiscomplete,checkthechecklistitemsbeforedoingatestrun.
■Besuretocorrectanyproblemsdiscovered.(Failuretodosowillnotonlypreventfeaturesfrom
operating,itwillalsoimperilyoursafety.)
■Checklist
Check items Remedyforproblem Checked?
Installation
Is the main unit mounting strong
enough? Reinforceit.
Is the main unit attached securely? Tightenthemountingscrews.
Is the panel securely closed? Close the panel.
Didyoucaulk?(Theairsupply/
exhaust pipe should be caulked
outside, as should the outdoor hood.)
Caulk.
(Failure to caulk will allow rainwater
inltration.)
Before
operation Are you using the rated voltage? Applytheratedvoltage.(Usingother
voltages will damage the unit.)
Operating
checks
Are switch operations consistent with
Lossnay operations?
(VL-100EU5-Eonly)
Thewiringisincorrect.
Re-dothewiringaccordingtothe
connection diagram.
Do you hear the blades hitting
anything?
Openthepanel,removetheairlter,and
take out any debris (only in the areas you
can see).
Does the unit make any unusual
sounds when starting or stopping? Attach tightly to the wall so the air supply/
exhaust pipes and pipe mounting plates do
notshift.
Does the shutter work smoothly?
