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 ventilation
In 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 air volume.
6) Do not use the heater outside the set air volume.
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.
