NOTE
- CHOOSE THE GRILLE AMONG THE DEDICATED GRILLES.
- REINFORCE THE SUSPENSION BOLT FOR EARTHQUAKE-RESISTANCE AS NEEDED.
- FOR THE SUSPENSION BOLT. USE MIO OR W318. (PROCURED AT THE LOCAL SITE.)
- FOR DRAIN PIPE, USE VP-25(0.D. n1-1/4″(1 32) PVC TUBE). DRAIN PUMP INCLUSION. RAISE IS MAX 33-1/16,850mm) FROM THE CEILING.
- ELECTRICAL BOX MAY BE REMOVED FOR THE SERVICE PURPOSE. MAKE SURE TO SLACK THE ELECTRICAL WIRE LITRE BIT FOR CONTROUPOWER WIRES CONNECTION.
- THE HEIGHT OF THE INDOOR UNIT IS ABLE TO BE ADJUSTED WITH THE GRILLE ATTACHED.
- REQUIRES “E” OR MORE SPACE BETWEEN TRANSOM AND CEILING FOR THE INSTALLATION.
- WHEN INSTALLING THE BRANCH DUCTS, BE SURE TO INSULATE ADEQUATELY. OTHERWISE CONDENSATION AND DRIPPING MAY OCCUR. (IT BECOMES THE CAUSE OF DROPLET OR DROPLET DRIPPING.)
- AS FOR NECESSARY INSTALLATION/SERVICE SPACE, PLEASE REFER TO THE RIGHT AT FIGURE.
- FOR THE INSTALLATION OF THE OPTIONAL HIGH EFFICIENCY FILTER OR MULTI-FUNCTIONAL CASEMENT,REFER TO SPECIAL DRAWING.
