<Duct piping>
Make sure to insulate ducts down to the base of the duct connecting anges.
Exposed parts get cold in winter, which may result in dew condensation forming due to moisture in the room.
Do not allow duct piping to contact the inspection opening,ceiling hanging bolts, beams, pillars, and other
duct piping.
Failure to heed this warning may result in abnormal noise and vibration.
Use an outdoor hood, that makes it less likely for rain water,snow or small animals (e.g. bats) from entering
the ends of the supply air and exhaust air ducts.
To prevent the entry of small animals, install an outdoor hood having louvers 2 cm or less wide.
When the Lossnay unit is anticipated not to be operated continuously, insulate the RA (Return Air) side ducts.
Indoor humidity can cause condensation because exposed parts can become cold in winter.
Place the duct heaters (supply air preheaters, supply air after-heaters) at least 2 m from the product.
Failure to heed this warning may cause damage on the product due to the preheating from the heaters.
<Drain piping>
Make sure to connect drain piping by the following procedure to prevent freezing and dew condensation
forming on the surface of the piping
- Connect the drain piping on the indoor side of the insulation layer
- Insulate the drain piping up to the end of the piping
- Do not let the end of drain piping be immersed in the rain gutter, etc.
(At times of heavy snow, the rain gutter freezes and drain water is not discharged, which results in water leaking

- At regions where salt damage is a concern, use an exclusive outdoor hood.
- At regions where salt damage is a concern, parts may have to be replaced sooner because of the deterioration of materials
that are used.
- At the outdoor hood installation position, allow at least 3x the diameter of the duct through holes between the outdoor
hood and the ducts so that exhaust air is not mixed in with supply air. (Preferably a distance of 450 mm or more should be
ensured between the outdoor hood and the ducts.)
- Donotconnectductpipesinthewaysshownbelow.(Failuretoheedthiswarningmaycausetheairowtodecreaseor
result in abnormal noise.)
- Use an exhaust air lter that has a non-woven fabric type lter.
- To reduce the noise of drain discharge, make sure to connect commercially available check valves to the drain
piping. Use check valves in line with their instructions.
- The opening face of the drain piping edge must have a vertical downward lack of water. Make the opening at the
