Note
- When discharging the air from a bathroom, use ducts made of
a material that does not allow water to leak.
- When using PVC ducts or metal ducts for the SA side ducts,
make sure to connect ducts having silencer before the grill.
- The duct for exhaust from the bathroom and the pipe guide
should be sealed with caulking material.
- When using calking material, take care to prevent it from
oozing from the ducts. (Otherwise, it could cause aluminum
tape to peel off.)
- Before connecting the ducts, make sure that there are no metal
chips or other foreign matter (For example paper or vinyl)
inside the ducts or inside the product.

■ Post-installation Checks
When you have finished installation work, perform trial operation following the installation manual of the
Lossnay unit, and check for air leakage or abnormal vibration from the joint parts of the Lossnay unit and
silencer box. Inspect the following items according to the following Check list before turning the power on.
Make sure to correct any malfunctions that are found. (The functions is not being demonstrated or safety can not
be ensured)
Are the Lossnay, silencer box and the duct piping installed on the indoor side
of the insulation layer/airtight layer?
Installation of
Are the Lossnay and silencer box installed within ±1° of the horizontal?
the product
Are the joint parts of the Lossnay unit and silencer box sufficiently caulked?
(Insufficient caulking may cause water leakage, sound leakage, and air
leakage.)
Is the outdoor side duct installed tilted 1/30 or more towards the outside to
prevent rain water from entering?
Are there metal chips or other foreign matter (for example paper or vinyl)
Duct
inside the product or the ducts?

Are ducts insulated down to their base?
* See 3.4.2 Insulating the ducts at 3. Installation Procedure.
Are ducts connected to the product? (Air leakage causes dew condensation.) Securely connect the ducts

3.4.2 Insulating the ducts
CAUTION
To prevent dew condensation, insulate the ducts and pipe
guide. (glass wool 25 mm or equivalent)
Make sure to insulate up to the base of pipe guide.
When the Lossnay is anticipated to be stopped for a long
time, insulate the RA (Return Air) side ducts also. (i.e. not
operated for 24 hours).
Indoor humidity can cause condensation because exposed
parts can become cold in winter.
