3 Example of fixing outdoor unit by anchor bolts.
1. Max. 17 mm (After cut “A”)
2. Concrete
3. Anchor bolt

4 Provide an adequate drainage around the foundation. When installing the unit on a roof or a veranda, drain water may
turn to ice in a cold morning. Therefore, avoid draining in an area where people often use because it is slippery. In case
of installing such a place, provide the additional drainage around the foundation.
1. Drain hole (30x80)
2. Drain hole (3-30x80)
3. Front side
5 The whole of the base of the outdoor unit should be installed on a foundation. When using vibration-proof mat, it should
also be positioned the same way. When installing the outdoor unit on a field-supplied frame, use metal plates to adjust
the frame width for stable installation as shown in Figure.
1. Outdoor unit is unstable
2. Frame
3. Outdoor unit is stable
4. Metal plate
A. 57 mm. Base width of outdoor unit
B. 40 mm Frame width (Field-supplied)
C. 100 mm or more Metal plate
• Recommended Metal Plate Size:
– (Field-Supplied) Material: Hot-Rolled Mild Steel.
– Plate (SPHC) Plate Thickness: 4.5 T
