1. Features

(1) Normal body

) . Economic and convenient installation

---Several diffusers branch off from an indoor unit, adjusting the room temperature, which makes

many rooms to be air-conditioned with only one indoor unit.

--- All models feature thin design making them applicable to ceiling pocket that tends to be shallow

---Thinner body than the former, 298mm height is easier for installation and saving space.

* . A wild variety of optional accessories

---Including front clapboard, panel, canvas air passage, filter, etc.

Canvas air passage Clapboard

Panel

+ . A long-life and high-efficiency filter

, . Way of air intake and inserting air filter

---Air intake can be positioned either at the back or below the unit. Similarly, the air filter also can be

inserted either from the back or from the bottom of the unit.

YUHA 36 FT

YUHA 36 FT

YUHA 48 FT

Symbols:

MCA: Min. Circuit Amps.

MFA: Max. Fuse Amps..

FLA: Full Load Amps.

Kw: Rate Motor Output

Notes:

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

8. Maximum allowable voltage variation between phase is 2%

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

10. 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.
