Safety Notes - Mitsubishi Electric VL-350CZPVU-R-E Quick Start Manual

■Features of Lossnay
1. A Lossnay unit provides 24-hour ventilation for the entire house. The heat recovery system provides fresh air at a
comfortable air temperature.
2. With simple wall-mount design, the units can be easily installed in compact places in houses such as the roof
space, hallway cupboard, kitchen, etc.
3. Airflow can be adjusted within the range between 25% and 100% by 1% to meet the designed airflow rate.
4. Lossnay can be monitored and controlled via MELCloud from anywhere an internet connection is available.
*MELCloud is a Cloud-based solution for controlling Lossnay either locally or remotely by computer, tablet or
smartphone via internet.
5. The quiet operation is achieved with the fan designed for only th
6. Optional high efficiency filters can be installed inside the unit without any filter box, which saves space.
7. By using 0-10V signal from the controller(local supply) such as the humidistats and CO2 sensors, the airflow of
the Lossnay unit can be changed. It is also connected to the light switch(local supply) and can change to the
boost operation(Input 220-240V). It allows the fan speed to automatically change according to the bathroom
occupation, the CO2 level, and the humidity level.
8. It is possible to select manual switching or automatic switching between "Lossnay ventilation (with heat
exchange)" and "By-pass ventilation (without heat exchange)".
9. Operating temperature range is down to -15℃. With a pre-heater, it is available down to -25℃.
■Caution for installation
【Ventilation design】
1. For the outside air intake vent, choose a position where combustion gas or other similar exhaust air is not sucked
in and the vent is not buried by snow.
2. Do not install the product at locations where the product is prone to be damaged from salt or hot springs. Failure
to heed this warning may result in malfunction of product.
3. Do not install the product at locations where toxic gas or gas containing corrosive components such as acids,
alkaline, organic solvents, or paints is generated.
4. Do not install the product near bedrooms.
5. For living rooms (e.g. bedrooms) where it is anticipated that building ambient noise will be below 30 dB(A), use
commercially available ducts that have sound deadening qualities on the supply air side.
6. Install supply air and exhaust air grills at locations where they are less likely to reverberate.
7. In cold regions or regions with strong winds, wind outside sometimes gets inside when operation of the product is
stopped. So, we recommend providing a motorized shutter midway along the supply air and exhaust air ducts.
8. Install the product so that discharged gas or exhaust air from burning appliances and equipment does not flow
back inside the product.
9. Use an outdoor hood, that makes it less likely for rain water, snow or small animals (e.g. bats) from entering the
ends of the supply air and exhaust air ducts.
10. At the outdoor hood installation position, allow at least 3x the diameter of the duct through holes between the
outdoor hood and the ducts so that exhaust air is not mixed in with supply air. (Preferably a distance of 450 mm
or more should be ensured between the outdoor hood and the ducts.)
11. In areas where the outdoor air is below -20℃, electric shutters(local supply) is required in the OA duct in addition
to the pre-heater. With the pre-heater, the OA temperature must be higher than -15℃.
12. Do not use duct booster fan on the RA/EA duct or the OA/SA duct. If an external force is applied to the built-in
bypass damper, the damper may be fixed on the bypass side, when it is switching between Lossnay mode and
Bypass mode, and heat recovery may be prevented.
【Installing the Lossnay unit】
1. The unit is exclusively vertical mounting type.
2. Do not install the product in hot places in the direct sunlight and in smoky places.
3. Do not install the Lossnay unit or the remote controller in a bathroom or other humid location.
4. Install the product and the duct piping on the indoor side of the insulation layer/airtight layer.
5. Install the product (on the wall) in the direction of the duct connecting flange so that it is horizontal (within ±1°).
