Installation Instructions
Models LGH-F300, F470, F600RX
This product needs to be installed properly in order to ensure maximum functionality as well as safety.
Please make sure to read this installation manual before starting the installation.
Installation must be performed by a dealer or installation contractor. Please note that improper installation may cause malfunction or accident.
Separate booklet "Operating Instructions" is provided for the customer. The booklet and this manual must be handed over to the customer after completing the installation.
Safety precautions
The following signs indicate that death or serious injury may be caused by failure to heed the precautions described below.
Do not modify or disassemble.
(It could cause fire, electric shock or injury.)
Do not
The Lossnay unit and remote controller should not be installed
where it is highly humid, like a bathroom, or other wet place.
(It could cause electric shock or power leakage.)
Prohibition of use in
bath or shower room
Connect the product properly to ground.
(Malfunctioning or power leaks can cause electrical shock.)
Connect the
grounding wire.
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
(104˚F (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, alkaline gases,
organic solvent fumes, paint fumes, or gases containing
corrosive components are generated.
(It could cause malfunction.)
Do not install this product in a place where it is exposed to
ultraviolet light.
(UV may damage covering insulation.)
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.
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.
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.

Use the specified power supply and voltage.
(Use of incorrect power supply or voltage could cause fire or electric shock.)
Select a place with sufficient strength and install the main unit securely.
(It could cause injury if it falls.)
Wiring work must be performed by qualified professionals, and be
implemented safely and securely in accordance with the engineering
standards and the extension wiring rules for electrical equipment.
(Poor connection or improper wiring work could cause electric shock or fire.)
Install a power supply isolator at the power supply side as per local
electrical regulations. All supply circuits must be disconnected before

given must be
connect the cables securely to prevent disconnection when they are pulled.
(If there is a defect in the connection, there is a possibility of fire.)
Select an adequate place for the opening to introduce outdoor
air, where it will not intake the exhaust fumes like combustion
gas, or others, and there is no risk of blockage.
(Shortage of fresh air could put the room in a state of oxygen deficiency.)
A duct made of steel must be installed with care not to be connected
electrically with metals such as metal , wire , stainless steel plate, or others.
(It could cause fire when power leakage occurs.)
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
and correctly rated wire / chain hangers. (Use of hardware with
insufficient strength could result in the product dropping.)
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,
The instructions
given must be
or damage to household property.)
The control box cover must be closed after the installation.
(Dust or humidity may cause power leakage or fire.)
When connecting external devices (electrically operated 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.)
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.
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: 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)
