(Note)
1. Performance of operation to top up in intermediate season shows the capacity measured under the conditions that outdoor air temp is 16°C
DB/12°C WB, water inlet temp is 17°C and hot water outlet temp is 65°C.
2. Performance of operation to top up in cold region shows the capacity measured under the conditions that outdoor air temp is –7°C DB/–8°C WB,
water inlet temp is 5°C and hot water outlet temp is 90°C excluding heater for anti-freezing water (345W).
3. Operating sound shows a value measured at 1m in front of the unit and 1m above the floor in anechoic room where the sound is resonated a little.
Accordingly if the unit is installed on actual site, it is normal that the measured sound there is higher than the value shown above, because it is
influenced by surrounding noise and echo in the room.
4. The actual hot water outlet temp may vary ±3°C from target temp according to the change of outdoor
air temp and water inlet temp. And then if feed water inlet temp is 30°C or higher and outdoor air temp
is 25°C or higher, hot water outlet temp may be controlled not to increase too high.
5. Please use the clean water. The water quality should follow a guideline of JRA-GL. 02:1994.
If the water quality is out of the standard, it may cause troubles such as scale buildup and/or corrosion.
6. These articles mentioned above may vary without any notice according to the development status.

According to the installation conditions,
please take a measure to prevent from
falling, cross wind and heavy snow.
