Rated conditions
• (Low*): When the supplied external static pressure line switching connector is connected.
• The numerical value within the parenthesis of fresh air conditioning load throughput is value of the heat recovery amount due to total heat
exchange.
• As for the Direct-Expansion Coil efficiency, when it is run under the test conditions stated below
Cooling: Direct-Expansion Coil port temperature 27 °C DB and 19 °C WB (discharge air), Outdoor air inlet temperature 35 °C DB and 24 °C
WB (charge air).
Heating: Direct-Expansion Coil port temperature 20 °C DB (discharge air), Outdoor air inlet temperature 7 °C DB and 6 °C WB (charge air)
• Efficiency of the total heat exchanger depends on the following conditions.
Summer: Indoor temperature 27 °C DB & 20 °C WB (discharge air), Outdoor temperature 35 °C & DB 29 °C WB (charge air).
Winter: Indoor temperature 20 °C DB & 14 °C WB (discharge air), Outdoor temperature 5 °C & DB 2 °C WB (charge air).
• The operation sound is measured when the unit is connected to the duct and operated in the anechoic room, associated with the value
measurement directly 1.5m from under the unit.
Once true installation effects taken into account, the actual levels will exceed the indicated values due to reflections off adjacent surfaces and
peripheral noise.
• The changes of H/L of external static pressure depend on the plug equipped connector. However, it will not affect the remote control indication
and will display the HIGH mark.
• This unit has no solvent resistance. Please pay attention to the installation site.
