PURY- (E)P200-550YNW-A2 If the CMY-R160-J1 joint is not used for P/M100-140, the capacity should be multiplied by the correlation factor 0.97.

Piping Length

Item| Pipe Section| Max Length
Total piping length| A+B+a+b+c+d| See Chart 1
Furthest piping length| A+B+d| 165 m
Length between OU & BC| A| 110 m (See Chart 1 on Page 8)

3. 90 m is available depending on the model and installation conditions. Please refer to design tool schematic & ‘Height Check’ document.
4. 60 m is available depending on the model and installation conditions. Please refer to design tool schematic & ‘Height Check’ document.
5. Distance of Indoor sized P200, P250 from BC must be less than 10 m.
6. Distance of Indoor sized P200, P250 from BC must be less than 20 m.

PURY- (E)P400-1100YSNW-A2
Outdoor Twinning Kits:

When outdoor units equal to or larger than size P950, please ensure to use BC controller CMB-P1016V-KA1.
If the CMY-R160-J1 Joint is not used for P/M 100-140, the capacity should be multiplied by a correction factor 0.97.

1. See chart 2 for maximum distance based on height difference (Page 8).

2. When P200 or P250 indoor units are connected to the system, the maximum distance from the BC controller to the farthest indoor unit is 40 m.

3. 90 m is available depending on the model and installation conditions. Please refer to design tool schematic & ‘Height Check’ document.

4. 60 m is available depending on the model and installation conditions. Please refer to design tool schematic & ‘Height Check’ document.

5. Distance of Indoor sized P200, P250 from BC must be less than 10 m.

6. Distance of Indoor sized P200, P250 from BC must be less than 20 m.

7. If height difference between BC Controller and indoor unit is zero, then 90 m is possible (Refer to Chart 3 On page 9). Increase the size of the high-pressure pipe and the liquid pipe between the main BC and sub BC by one size.
   When using P/M32, P/M40, P/M50, P/M100, or P/M125 model of indoor units, increase the size of the liquid branch pipe between the Sub BC and indoor unit by one size. When using indoor models P/M140 or larger and if height difference between BC Controller and indoor unit is zero, then the restrictions of 60 m cannot be exceeded.

8. When using 2 Sub BC controllers, max. height ‘’h3’’ is 10m.
