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
di󰀨erence 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)
lDo not transfer and keep the product at vertical position.

4.2 Duct works
4.2.1 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 the supply air is set twice as much as the exhaust air or
more by airow function, the Lossnay body indoor side must
be put additional insulation. Without additional insulation, it
could cause condensation and water drop from the unit.
• 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.
