    8
  • 2. Mount a snowfall-hood onto the air inlet and the air outlet.

    8
  • 1. To install multiple outdoor units, arrange them with 20mm or more spaces in between. Fix each outdoor unit with M12 anchor bolts at 4 positions. 20mm projection is appropriate for an anchor bolt.

    8
  • 2. When drawing out the refrigerant pipe from the underside, set the height of the stand to 500mm or more.

    9
  • 3. Do not use 4 stands on the corner to support the outdoor unit.

    9
  • 4. Mount the vibration-proof rubber (including vibration-proof blocks) so that it fits under the whole clamping leg.

    9
  • 5. Be careful of the connecting arrangement of the header unit and follower units. Set the outdoor units in order of capacity from the one with the largest capacity. (A (Header unit) ³ B ³ C ³ D)
