Operation
1. For connection of a remote controller (PZ-41SLB-E)
If the Lossnay’s operation is linked with the operation of an external device such as an air conditioner, the method of use will differ, so carry out
the appropriate operation in accordance with the following table. Also, please see the installation and user’s manual for the remote controller
(PZ-41SLB-E).

Operation
Run using the remote
controller.
If an external device is
connected the “On/Off”
function of this device will
also control the Lossnay
operation.
• If 2 remote controllers are used, the last
controller to be used has priority. (Last
Command)
• If you would like to turn ON the Lossnay
alone while the external device is OFF,
operate it by the Lossnay remote controller.
• The fan speed is on “High”.
• The ventilation mode is “Ventilation Mode
Auto Select”.
2. For connection of a Lossnay remote
controller (PZ-52SF-E), Mitsubishi
Electric Air-Conditioner Network
System (MELANS) or City Multi.
This is to be incorporated and used in the Mitsubishi Electric AirConditioner Network System.
This is interlocked with the City Multi and operated by it.
If the Lossnay remote controller (PZ-52SF-E) is used, the Lossnay
may be operated independently if connected to City Multi.
For details, refer to the operating manual of PZ-52SF-E.
Lossnay operation using the Lossnay remote controller (PZ-52SFE) should need the power supply unit. Refer to the system diagram
below.
Note
• If this is to be used with the Lossnay remote controller (PZ52SF-E), refer to the manuals for both the PZ-52SF-E installation and operating manual.
• Remote controller PZ-41SLB-E cannot be used with this system.

■ LOSSNAY VENTILATE setting
Both fresh air supply and return air pass through the Lossnay core(s).
Resulting in full heat exchange. Lossnay ventilate setting is used for
cooling in the summer and heating in the winter period.

Operation (Continued)
English
1. Reduces cooling load
If the air outside is cooler than the air inside the building during
the cooling season (such as early morning or at night), “By-pass”
ventilation will draw in the cooler outside air and reduce the cooling load on the system.
2. Night purge
“By-pass” ventilation can be used to release hot air from inside
the building that has accumulated in buildings a business district
during the hot summer season.
Maintenance
Remove all dust and dirt on air filters and Lossnay core(s) at regular
intervals in order to prevent a deterioration in the Lossnay functions.
Guideline: Clean the air filters once a year.
Removing the parts
1) Maintenance cover
Locate and remove the cover fixing screw. Pull back the hinged clip.
Open the door and lift off of the hinge brackets.
Hinge
Clean the Lossnay core(s) once two year.

3. Office equipment room cooling
During cold season, outdoor air can be drawn in and used as is
to cool rooms where the temperature has risen due to the use of
office equipment.

* The values given in the table for the noise level reflect the levels measured at a position 1.5 meters immediately below the unit in an anechoic
chamber.
* The noise at the air outlets is the values at a 45° angle, 1.5 meters in front of the unit.
* The above values apply during Lossnay ventilation when the fan speed is set to high speed.
* The values for 150 and 200 type main unit outlet noise show in the case of 1 supply air duct.
