LOSSNAY core removal side.

•Always insulate the two ducts outside the room (intake air and exhaust

air ducts) to prevent condensation.

•It is possible to change the direction of the outside air ducts

(OA and EA side).

•Do not install the vent cap or round hood where it will come into

direct contact with rain water.

•

Always leave inspection holes ( 450 or 600) on the air filter and

LOSSNAY core removal side.

•Always insulate the two ducts outside the room (intake air and exhaust

air ducts) to prevent condensation.

•If necessary, order a weather cover to prevent rain water from direct

Attention for specifications

1.Cold operation mode(*1) is to start repeating in the case that LOSSNAY's detected OA temperature is less than-10°C.

*1.Supply air(SA) in the operation for 60min. followed by stop operation for 10min.

2.The current, power consumption and efficiency are based on the air flow rate in the specification.

3.Fan speed is selectable by the remote controller from High (Extra-High), Low, Extra-Low(Extra-Low not equipped LGH-

150RX

5 and 200RX

5).

Multi Ventilation Mode should set on LOSSNAY unit or remote controller (PZ-60DR-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 By-pass ventilation is set by remote controller.

Remote controller continue to show "By-pass 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)

Attention

1.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 prop-

erly 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 (450

450 or 600

600mm)must be installed on the filter and LOSSNAY core removing side.

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 presticide,

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.By-pass ventilation

In the case of "By-pass" 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 sup-

ply 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.Leaving sufficient space for maintenance purpose.

3.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.

4.Take precautions when using the product in quiet location.

5.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 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.

6.Prevent entry of rainwater into LOSSNAY unit

Install weather louvre 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.

1)Install the anchor bolts to ensure the product's weight or earthquake load. (Correctly rated wire/chain may also be used)

2)Do not install this product in a place where it is exposed to ultraviolet light. (UV may be damage covering insulation.)

7.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)
