Safety precautions (continued)
CAUTION
Do not place a burning appliance in a place where it is
exposed directly to the air from the Lossnay unit.
(It could cause an accident as a result of incomplete combustion.)
Do not use at a place where it is exposed to high
temperatures (40˚C or higher), naked flames, or in
environment with combustible fumes.
(It could cause fire.)
Do not use in an environment such as a chemical
factory, where hazardous gases such as acidic gases,
Prohibited alkaline gases, organic solvent fumes, paint fumes, or
gases containing corrosive components are generated.
(It could malfunction.)
Do not install this product in a place where it is
exposed to ultraviolet light.
(UV may damage covering insulation.)
Put on gloves during installation.
(It could cause injury.)
Make sure the power supply isolator is turned off on
the power distribution panel when Lossnay is not
used for a long period of time after the installation.
(It could cause electric shock, power leakage, or fire as a
result of deteriorated insulation.)
Always use the specified suspension bolts, nuts and
washers or correctly rated wire / chain hangers.
The instructions

followed.
The outside ducts must be tilted at a gradient (1/30 or
more) down toward the outdoor louvres from Lossnay,
and properly insulated.
(The entry of rain water may cause power leakage, fire, or
damage to household property.)
l When using the product where it is exposed to high temperatures
and humidity (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, 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.
Eng-2
The control box cover must be closed after the
installation.
(Dust or humidity may cause power leakage or fire.)
When connecting external devices (electric heater,
damper, lamp, monitoring unit, etc.) using output
signals of the Lossnay unit, make sure to install safety
equipment for the external devices.
(It could cause fire, damage, etc. without safety equipment.)
Select a duct heater in compliance with local and
national laws, ordinances, and standards.
Select a duct heater that has obtained the CE mark.
Install the duct heater separated from the product by a
distance of 2 m or more.
(Failure to do so may result in fire or equipment damage
due to the transmission of residual heat from the heater.)

CAUTION
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 confirm the operating
conditions and other precautions, and do not use the product if
dewing or freezing is anticipated.
*Example of dewing condition - Outdoor air: -5˚C or lower, dew-point
temperature at installation place: 10˚C or higher (When the indoor
temperature is 22˚C or higher with the relative humidity higher than
50%, or other)
