1. Features

(1) Low operation noise

---Streamline plate ensures quietness

---Creates natural and comfortable environment

(2) Efficient cooling

---Equal, fast and wide—range cooling

(3) The adoption of the most advanced 3- Dimensional Screw fan

---Reduces the air resistance passing through

---Smoothes the air flow

---Makes air speed distribution to the heat exchange uniform

(4) Fresh air makes life healthier and more comfortable.

(4) Improvement for easy installation and maintenance (only available for small four-way cassette)

---Little space is required for installation into a shallow ceiling

---Because of the compactness and weight reduction of the main unit and panel, all models can be

installed without a hoist

Notes:

1. Nominal cooling capacities are based on the following conditions:

Indoor temp: 27°CDB, 19°CWB; Outdoor temp: 35°CDB; Equivalent ref. Piping: 7.5m(horizontal)

2. Nominal heating capacities are based on the following conditions:

Indoor temp: 20°CDB; Outdoor temp: 7°CDB, 6°CWB; Equivalent ref. Piping: 7.5m(horizontal)

3. Actual noise level may differ, depending on the room structure, etc, since these noise values are from an anechoic room.

Symbols:

MCA: Min. Circuit Amps.

MFA: Max. Fuse Amps..

FLA: Full Load Amps.

Kw: Rate Motor Output

Notes:

5. Voltage range should not over the value of above table.

6. Maximum allowable voltage variation between phase is 2%

7. Selection wire size based on the larger value of MCA.

8. MCA/MFA

MCA = 1.25 × FLA

MFA ≤ 4 × FLA

(Next lower standard fuse rating min. 15A)

5. Instead of fuse, circuit breaker is also acceptable.
