Notes:
1. The cooling conditions: indoor temp.: 27℃DB, 19℃WB, outdoor temp.: 35℃DB, water inlet temp. :30℃, equivalent pipe length:
5m, drop length: 0m.
2. The heating conditions: indoor temp.: 20℃DB, 15℃WB, outdoor temp.: 7℃DB, 6℃WB, water inlet temp. :20℃, equivalent
pipe length: 5m drop length: 0m.
3. Sound level: Anechoic chamber conversion value, measured at a point 1 m in front of the unit at a height of 1 m. During actual
operation, these values are normally somewhat higher as a result of ambient conditions.
4. Connection piping diameter of single-unit is the stop valve diameter of the unit.
Connection piping diameter of multi-unit is the main pipe connecting to the first indoor branch joint, is case of the total equivalent
liquid length is less than 90m. If the total equivalent liquid length is more than 90m, please refer to technical manual to choose the
connection piping diameter.
5. The farthest equivalent pipe length should be equal to or shorter than 40m, but it can be up to 90m if meet the required
conditions following part 4 installation sections.
The above data may be changed without notice for future improvement on quality and performance.
