Branching Requirements: Pipe connections between outdoor units require specific T-shape branching joints, while indoor-to-outdoor connections require Y-shape branching joints or headers.
Electrical Safety: The unit must be connected to an exclusive power supply via a switch with at least 3 mm of contact separation. 3416 - Toshiba MMY-MAP0802FT8-E.pdf - HOS BV
