CAUTION
lWhen using the product where it is exposed to high temperatures
and humidity (104 ˚F (40 ˚C) or higher, RH 80% or higher), or where
fog occurs frequently, moisture is likely to condense in the core,
and may result in condensation build up in the unit. The product
should not be used under such conditions.
lOutdoor air may enter the Lossnay owing to the pressure
difference between indoor and outdoor or external winds even
when the product is not operated. It is recommended to install an
Electrically operated damper to block the outdoor air.
lIn a cold weather area where outdoor temperature becomes lower
than 23 ˚F (-5 ˚C), an area with strong external winds or where fog
occurs frequently, cold outdoor air, external winds or fog may be
introduced into the product when its operation is stopped. It is
recommended to install an Electrically operated damper.
lWhen using the product in an environment where there is a
window, or opening near the outdoor louvre , where insects are
likely to gather around the interior or exterior light , take note that
small insects may intrude into the product.
lIn a cold weather area, or others, dewing or freezing could
occur on the main unit, where the duct is connected, or other
sections, depending on the conditions of outdoor air and indoor
temperature and moisture, even if they are within the range
of operating conditions. Make sure to conrm the operating
conditions and other precautions, and do not use the product if
dewing or freezing is anticipated.
*Example of dewing condition - Outdoor air: 23 ˚F (-5 ˚C) or lower, dew-
point temperature at installation place: 50 ˚F (10 ˚C) or higher (When
the indoor temperature is 71.6 ˚F (22 ˚C) or higher with the relative
humidity higher than 50%, or other)

Electrically operated damper
(Protection against the intrusion of cold air
while Lossnay is stopped in winter)
(To be provided by the customer)
• In a region where there is risk of freezing in winter, it is
recommended to install an Electrically operated damper, or the like,
in order to prevent the intrusion of (cold) outdoor air while Lossnay
is stopped.
CAUTION
• Do not install Lossnay unit vertically or on an incline.
Installing the Lossnay unit
1. Attaching the duct connecting anges
Use the supplied small screws to secure the duct connecting
anges to the Lossnay unit.
CAUTION
• Before attaching the duct connecting anges, check that no
foreign matter (scraps of paper, vinyl, etc.) has found its way
inside to Lossnay unit.
• Attach the duct connecting anges with the packing at the SA
and RA sides.
• Alway use accessory screws. Otherwise the screw may
interfere internal parts and result abnormal operation.
2. Securing the ceiling suspension xtures
Models LGH-F300 to F600RVX-E
(1) Loosen the screws for the ceiling suspension xtures.
(2) Rotate the ceiling suspension xtures 90° centered around the
loosened screws to make them horizontal.

• Extreme reduction in
the diameter of the
connected ducts
5. Connecting the ducts
(1) Fasten the duct securely to the duct connecting ange, and
wrap aluminium tape (eld supply) around the joints so that
there is no air leakage.
(2) Suspend the ducts from the ceiling so that their weight will not
be applied to the Lossnay unit.
(3) The two outdoor ducts must be covered with heat-insulating
material in order to prevent condensation from forming.
CAUTION
• When on-site commissioning is planned, a straight duct
length more than 10xD (D=duct diameter) from the source of
turbulence like bends, contractions and dampers etc, to the
measurement point is recommended for correct measurement.
In the United Kingdam, on-site measurment should therefore be
measured in accordance with BSRIA guideline (Commissioning
Air System. Application procedures for buildings AG3/89.3(2001))
• Before attaching the ducts, check that no (debris or any other)
foreign matter (scraps of paper, vinyl, etc.) has found its way
inside the ducts.
• Do not touch the damper plate inside Lossnay unit when
connecting the ducts.
• If it is expected that the ambient temperature around the place
where the Lossnay unit is installed will be high during the
summer air conditioning season, it is recommended that the
indoor duct work be covered with insulation material.
Do not carry out the following types of duct construction. (Doing so
could cause a drop in the air volume and generate abnormal noises.)

adjust in such a way that Lossnay unit is level.
(2) Tighten up securely using double nuts.
CAUTION
• When suspending Lossnay unit from the ceiling, do not handle
it in such a way that force will be applied to the control box.
• Install the anchor bolts to ensure the product's weight or
earthquake load. (Correctly rated wire/chain may also be used)
3. Preparing the anchor bolts
Mount the washers (outer diameter of >13/16 inch for 3/8-16 UNC
(21 mm for M10) >15/16 inch for 7/16-14 UNC (24 mm for M12)
and nuts onto the pre-recessed anchor bolts (3/8-16 or 7/16-14
UNC (M10 or M12)), as shown in the gure below .
[When using (customer-prepared) vibration isolation rubber]
When using (customer-prepared) vibration isolation rubber, there
is a possibility of this causing a decrease in strength, so we
recommend the following type of construction.

Lossnay changes fan speed according to input voltage to CN26.
When pattern X or Y is selected, it is not possible to change fan
speed from remote controllers.
(External input has higher priority)
[Pattern X]
When the input voltage is more than 6.0 VDC, Lossnay operates at
fan speed 4 (maximum air volume). Lower voltage than 6.0 VDC,
Lossnay operate at weaker fan speed. (Connection example: if you
use a CO2 sensor which 0 - 10 VDC equals to 0 - 2000 ppm, 6.0
VDC equals to 1200 ppm)
[Pattern Y]
When the input voltage is more than 5.0 VDC, Lossnay operates at
fan speed 4 (maximum air volume). Lower voltage than 5.0 VDC,
Lossnay operate at weaker fan speed. (Connection example,:if you
use a CO2 sensor which 0 - 10 VDC equals to 0 -2000 ppm, 5.0
VDC equals to 1000 ppm)
[Pattern Z]
Lossnay changes fan speed as the table below. (Connection
example: BMS (Building Management System))
Input voltage[VDC] Fan speed Fan speed changing from
