Other than EU countries
This appliance is not intended for use by persons (including children) with reduced physical sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

EU countries
This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.

When using the unit

• When running in winter, the Lossnay transfers the heat of indoor air to the cold outdoor air as it brings outside air in.

  • This means that when outside air is colder than about -10°C, condensation or frost may form on the panel or inside the unit.
    Since condensation and frost formation varies with subtle changes in conditions (indoor humidity, air flow and the like), switch operating Vmodes or temporarily stop the unit as conditions dictate.

• Check that the unit is mounted properly before using it.

  • Is the Lossnay mounted on a wall?
  • This Lossnay is designed to be mounted only on a wall. If mounted on a ceiling, it may drop off.
  • Is the special outdoor hood mounted on an exterior wall?
  • Failure to install the hood may allow wind and rain into the unit, damaging it.

• Obey the following cautions when using the Lossnay

  • Do not place objects around the unit.

  • Such objects may block air outlets or intake openings or may prevent servicing.

  • They may also prevent you from reaching the wall outlet (for plug-in models).

  • When an object (such as a bookshelf or a chest of drawers) is placed directly below the unit, orient the louver horizontally.

  • Failure to do so could result in a short circuit.

  • Wind may blow against the object and cause it to become dirty.

  • Do not use aerosol sprays (such as insect sprays, hair sprays or cleaners) directly on the unit.

  • The panel may warp, weaken, or become damaged.

  • Do not obstruct the panel.
    Proper ventilation may be impeded.

  • Do not pull the cord diagonally (VL-100U5-E only).

  • The unit will not operate correctly.

  • In the following cases, stop the Lossnay and close its shutter.

  • If the outside air is cold, winds are strong, snow or rain is falling heavily, there is heavy fog, or fine snow is falling. (Water or snow may infiltrate the Lossnay with the air supply, resulting in weather damage.)

  • During cleaning and inspections

(Stop the Lossnay temporarily, resuming operation later.)

• Mitsubishi recommends mounting the Lossnay away from the bed.
  If the unit is too close, you may hear operating noise or feel cold air blowing while in bed.

• Bugs smaller than the grate openings of the outdoor hood may be able to infiltrate the unit.

• The motor and the air filter require periodic maintenance (replacement). Replacement time will vary with frequency of use.

Features

The Lossnay ventilator, from Mitsubishi

Running the Lossnay
The Lossnay moves dirty indoor air outside (exhausting it) and brings clean air from the outside in (providing air supply).
When it supplies air, it brings outside air close to room temperature (functioning as a heat exchanger).

• The Lossnay is not an air-conditioner. It is a ventilating fan that exchanges heat as it ventilates.
• Since it not only sends indoor air out but also brings fresh air in, it works well in tightly sealed homes.
• Since it is a heat exchanger, it provides heating and cooling at a lower cost than ventilators that merely exhaust.
• Built-in filters reduce the amount of dust, pollen and other particles entering the house in outside air.
• To prevent freezing or damage to the Lossnay Core, stop the unit if the outside temperature falls below -10°C and the room’s humidity rises above 40%. (The other conditions about temperature and humidity are based on Table 1 as a reference.)
  Table 1

Names of parts

Before you start the Lossnay
Preparing to turn the power on

Note

• In the following cases, stop the Lossnay and manually move the shutter knob to the leftmost position (the closed position) to close the shutter.
• If the outside air is cold, winds are strong, snow or rain is falling heavily, there is heavy fog, or fine snow is falling. (Water or snow may infiltrate the Lossnay with the air supply, resulting in weather damage.)
• During cleaning and inspections

1. Slide the shutter knob to the open position.Note
   • Make sure that the shutter knob must be located in the open position, and then operate the unit. For VL-100U5-E
2. Switching operating modes

For VL-100EU5-E
Using the control switches.

• The switches shown above are only an example. Operations and indicators may vary depending on the switches installed.

If cold air is blowing on you
If cold air is blowing directly on you, flip the louver toward you to change the direction of air flow from vertical to horizontal.(Move manually .)

Maintenance

To maximize the life of the Lossnay, clean off any accumulated dirt and dust on the exhaust air  filter and outside air filter at least once every six months.

Warning

• Always shut off circuit breakers or, for the VL-100U5-E, remove the power plug from the wall outlet before performing maintenance work.
