Outdoor unit with a centrifugal fan
It uses HITACHI high pressure vertical compressor, which guarantees the adjustable capacity coeff icients characteristic of VRF systems.
To ensure optimal performance, the following guidelines should be followed:
| Piping Length | Maximum (meters) |
|---|---|
| Between Outdoor Unit and Furthest Indoor Unit | 100 |
| Total Length | 145 |
| Vertical Height Difference | 30 (Outdoor above Indoor) / 20 (Indoor above Outdoor) |
Correct sizing and installation are crucial for achieving peak performance and efficiency.
