The current, power consumption and efficiency are based on the airflow 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. Temperature Exchange efficiency (%) are based on winter condition.6. Mitsubishi Electric measures the machine according to the Japan Industrial Standards (JIS B 8628)

Attention1. 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 (600 × 600 or more) must be installed on the filter and Lossnay core removing side and under the fan motor maintenance cover.

4. SAMPLE INSTALLATIONS Lossnay

Lossnay model selection advices 1. Operating environment

Install this product in an environment where the temperature ranges from -10˚C to +40˚C and the relative humidity is less than 80%RH. If condensation is expected to form, heat up the fresh outside air should be treated.

2. Do not use under high temperature and humidity condition Condensation will occur and water will gather inside the Lossnay cores under high temperature and humidity condition, such as warm swimming pool, bathroom, greenhouse or foggy place.

3. Condition of outdoor, indoor and return air Avoid using Lossnay under air condition with acid, alkalis, organic solvent, oil mist, paint, or harmful gas as pesticide, corrosive gas, etc.

4. Insulation failure caused by salt or sulphur air and hot spring steam, rust, fire or malfunction may occur. Installing high quality filters inside outdoor air duct if the Lossnay operates in salt or sulphur air conditions.

5. Intake of mist or outdoor air during off-mode operation Outdoor air or mist may flow through the duct into your room when Lossnay is in off-mode at windy and foggy area. To prevent intake of outdoor air or fog, a damper is advised to be installed.

6. Entry of insects When using the product in an environment where there is a window, or opening near the outdoor hood, so that insects are likely to gather around the interior or exterior light, take note that small insects may intrude into the Lossnay filters.

7. Bypass ventilationIn the case of “Bypass” ventilation, the supply air temperature slightly rises more than the outside air temperature because of the effect around the ducts or the unit motors.

8. Usage of M-NET.When solely using Lossnay units, power supply unit is required to connect to centralized control. Number of power supply units or the transmission boosters should correspond with the connected Lossnay units.

Caution for installation 1. Do not modify the unit as it may cause malfunction. 2. Do not install Lossnay unit vertically or on an incline. It may cause malfunction or deterioration of performance. 3. Leaving sufficient space for maintenance purpose. 4. The location of the air inlet

Take care in locating air inlet to prevent intake of dirty air or disgusting smell from exhaust gas of factory, air from rubbish disposal, etc. 5. Take precautions when using the product in a quiet location. 6. Heat insulation foam for duct

Take care as below to prevent the contaminate ceiling by duct condensation. 1) The two outdoor ducts (OA and EA) must be covered with heat-insulating material in order to prevent condensation. 2) 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 should be covered with insulation material. 3) Outdoor air may come into unit during not operating unit by the pressure difference between indoor and outdoor or the outdoor wind.

In this case you should install a damper. 4) It is possible for condensation and freezing to occur in the cold regions inside the unit because of the outdoor air condition or humidity

condition above ceiling. Make sure to install supplemental insulation foam. 5) In the case that air condition around Lossnay unit is high temperature in summer, it is recommended that there are heat insulation

foam on indoor side duct to prevent heat recovery decreased by warming indoor duct. In winter, it is possible to cool indoor side duct without heat insulation foam on indoor side duct.

7. Prevent entry of rainwater into Lossnay unit Install weather louver or “Weather cover” for OA inlet & EA outlet. This is to prevent rainwater entering the Lossnay unit. Ducts to outdoor (OA and EA) should decline by 1/30 or more.

8. Install the anchor bolts to ensure the product’s weight or earthquake load. Correctly rated wire/chain may also be used. 9. Do not install this product in a place where it is exposed to ultraviolet light. UV may be damage covering insulation. 10. Electrical Work

A single pole isolator must be installed at the origins of mains power supply. Use single flush box, to support remote controller. Must connect ground wiring. When connecting external devices (electrically operated damper, lamp, monitoring unit, etc.) using output signals of the Lossnay unit, make sure to install safety equipment for the external devices. (It could cause fire, damage, etc. without safety equipment)

11. Duct heater In case of installing a duct heater interlock with Lossnay, be sure to observe followings.

1) Select a duct heater in compliance with local and national laws, ordinances, and standards. Select a duct heater that has obtained the CE mark.

2) Always select a heater that is equipped with a non-self-resetting safety device. Do not directly supply power from the Lossnay unit to the duct heater. Doing so could cause fire.

3) Install a circuit breaker for the duct heater in compliance with all applicable laws, ordinances, and standards. 4) Install the duct heater separated from the product by a distance of 2 m or more.

Failure to do so may result in equipment damage due to the transmission of residual heat from the heater. 5) When using a heater without a temperature control function, select a heater with a capacity that is matched to the airflow. 6) Do not use the heater outside the set airflow.

If the heater’s capacity is too larger, this may result in the heater frequently turning ON/OFF. If the heater’s capacity is too small, this may result an inability to heat.

7) Ensure that the duct heater and Lossnay are wired and that the Lossnay function settings have been configured, and then always check operation by trial operation.

Maintenance and lifetimeRefer to each model’s operation instructions for the suggested maintenance period and methods. General indication of lifetime of the main parts is as below. Time below is unrelated to guaranteed period for service. And parts exchange period varies with usage condition.Lossnay cores : Around 10 years with maintenance as stated periodsAir Filters : Around 5 years with maintenance as stated periods
