Standard installation examples
•The parts can also be installed upside down.
Remove the maintenance cover, rotate the parts by
180°, and re-install.
•In a region where there is risk of freezing in winter, it is
recommended to install an Electrically operated damper,
or the like, in order to prevent the intrusion of (cold) outdoor
air while Lossnay is stopped.

Attention for specifications
1.
Cold operation mode(*1) is to start repeating in the case that Lossnay's detected OA temperature is less than -10˚C.
*1.Supply air(SA) in the operation for 60min. followed by stop operation for 10min.
2.
The current, power consumption and efficiency are based on the air flow rate in the specification.
3.
Fan speed is selectable by the remote controller from fan speed 1, 2, 3 and 4.
Multi Ventilation Mode should set on Lossnay unit or remote controller (PZ-61DR-E).
4.
Lossnay ventilation mode is to start automatically in the case that Lossnay's detected OA temperature is less than +8˚C,even if
Bypass ventilation is set by remote controller.
Remote controller continue to show "Bypass ventilation" in this case.
5.

emperature Exchange efficiency(%) are based on winter condition.
6.
Mitsubishi Electric measures the machine according to the Japan Industrial Standards(JIS B 8628)
Attention
1.
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.
2.
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.
3.
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.
4.
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.
5. 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 damege to household property)
6.
The two outdoor ducts must be covered with heat-insulating material in order to prevent condensation from forming.
If it is expected that the ambient temperature around the place where the Lossnay unit is installed will be high during the summer
air conditioning season, it is recommended that the indoor ductwork be covered with insulation material.
7.
Inspection opening (450
×
450 or more)must be installed on the filter and Lossnay core removing side.
