Dimensions (unit: mm)
Daikin indoor unit Duct type
Daikin outdoor unit Duct type
Design flexibility
Designed for long refrigerant piping
70 m maximum length and 50 m maximum level difference to cover medium- and large-scale building needs.
High external static pressure
The outdoor unit has been achieved high external static pressure up to 78.4 Pa, ensuring the efficient heat dissipation and stable operation of equipment in either hierarchical or intensive arrangement.
Nighttime quiet operation function
The nighttime quiet operation function automatically suppresses the nighttime operating sound by reducing operation capacity to maintain the quiet environment of the neighborhood. Three selectable modes are available depending on the required level.
*1. Initial setting is 8 hours. Can be selected from 6, 8 and 10 hours.
*2. Initial setting is 9 hours. Can be selected from 8, 9 and 10 hours.
*3. In case of RZUR250PY1 (4)..
Notes:
- This function is available in setting at site.
- The operating sound in quiet operation mode is the actual value measured by our company.
- he relationship of outdoor temperature (load) and time shown above is just an example.

Space required for indoor unit installation (Unit: mm)
Space required for outdoor unit installation (Unit: mm)
1. Heights of walls in case of Patterns 1 and 2:
Front : 1500 mm
Suction side : 500 mm
Side : Height unrestricted
Installation space to be shown in this drawing is based on the cooling operation at 35 degrees outdoor air temperature.
When the design outdoor air temperature exceeds 35 degrees or the load exceeds maximum ability because of much generation load of heat in all outdoor unit,take the suction side space more broadly than the space to be shown in this drawing.
2. If the above wall heights are exceeded then h2/2 and h1/2 should be added to the front and suction side service spaces respectively as shown in the figure on the right.
3. When installing the units most appropriate pattern should be selected from those shown above in order to obtain the best fit in the space available always bearing in mind the need to leave enough space for a person to pass between units and wall and for the air to circulate freely.
4. The units should be installed to leave sufficient space at the front for the on site refrigerant piping work to be carried out comfortably.
(If more units are to be installed than are catered for in the above patterns your layout should take account of the possibility of short circuits.)
Specifications
Note:
*1. Indoor temp.: 27°CDB, 19°CWB / outdoor temp.: 35°CDB / Equivalent piping length: 7.5 m, level difference: 0 m.
*2. Anechoic chamber conversion value, measured at a point 1 m in front of the unit at a height of 1.5 m.
During actual operation, these values are normally somewhat higher as a result of ambient conditions and oil recovery mode.
When there is concern for noise the surrounding area such as residences, we recommend investigating the installation location and taking soundproofing measures.
*3. The value is the external static pressure with standard pulley.
