All supply circuits must be disconnected beforeobtaining access to the terminal devices. Use the specified cable size andconnect 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 outdoorair, where it will not intake the exhaust fumes like combustiongas, 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 connectedelectrically with metals such as metal , wire , stainless steel plate, or others.(It could cause fire when power leakage occurs.)Do not place a burning appliance in a place where it is exposeddirectly 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 withcombustible 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 containingcorrosive components are generated.(It could cause malfunction.)Do not install this product in a place where it is exposed toultraviolet 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 powerdistribution panel when Lossnay is not used for a long periodof time after the installation. (It could cause electric shock, powerleakage, or fire as a result of deteriorated insulation.)Always use the specified suspension bolts, nuts and washersand correctly rated wire / chain hangers. (Use of hardware withinsufficient 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 properlyinsulated. (The entry of rain water may cause power leakage, fire,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.)CAUTIONCAUTIONz 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 tocondense in the core, and may result in condensation build up in the unit. The productshould not be used under such conditions.z Outdoor air may enter the Lossnay owing to the pressure difference betweenindoor and outdoor or external winds even when the product is not operated. It isrecommended to install an Electrically operated damper to block the outdoor air.z 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 itsoperation is stopped. It is recommended to install an electrically operated damper.z When using the product in an environment where there is a window, or opening nearthe outdoor louvre , where insects are likely to gather around the interior or exteriorlight , take note that small insects may intrude into the product.z 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 ofoutdoor air and indoor temperature and moisture, even if they are within the rangeof operating conditions. Make sure to confirm the operating conditions and otherprecautions, 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)The instructionsgiven must befollowed.1109875HC4901
