Installation Procedure
•For installation of the adapter P.C. board and removal of the relay cable, be sure to wait for a while (approx. 1 minute) after turning off the power supplies of the air conditioner and the collective control remote controller. If not doing so, the adapter P.C. board may be damaged.
In case of 4-way Ceiling Cassette (RAV-SM **0 UT-E)
No. | Procedure |
|
|
1 | Using the spacer (C), install the adapter P.C. board to the position of the electric parts box of the indoor unit. |
|
|
2 | Using the 2 pcs. Ø4 x 14 tapping tight screws, install X, Y relay terminal block to the position of the electric parts box. |
•When tightening the screws, be sure not to damage the cable.
3Using 2 pcs. Ø4 x 6
tapping screws, install the transformer box storing the transformer to the position at side of the bell mouth.
4Using the relay cable (A), connect the X, Y relay terminal block with CN03 (Red) of the adapter P.C. board, and remote controller terminal block (A, B) with CN02 (Blue) of the adapter P.C. board using the relay cable (B), respectively.
Perform cabling between the yellow connector of the transformer and CN309 of the adapter P.C. board, and between white connector to CN01 of the adapter P.C. board, respectively.
