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).

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 Air-

Conditioner 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-52SF-

E) should need the power supply unit. Refer to the system diagram below.

Note

• If this is to be used with the Lossnay remote controller (PZ-

52SF-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.

■ AUTOMATIC VENTILATION setting

The automatic damper mode automatically provides the correct ventilation for the conditions in the room. The following shows the effect

“By-pass” ventilation will have under various conditions.

Operation (Continued)

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.

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.

(Only when interlocked with City Multi and Mr. Slim indoor unit)

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.

Clean the Lossnay core(s) once two year.

Removing the parts

1) Maintenance cover
