NOTE

  1. CHOOSE THE GRILLE AMONG THE DEDICATED GRILLES
  2. REINFORCE THE SUSPENSION BOLT FOR EARTHQUAKE-RESISTANCE AS NEEDED.
  3. FOR THE SUSPENSION BOLT, USE M10 OR W3/8. (PROCURED AT THE LOCAL SITE.)
  4. FOR DRAIN PIPE, USE VP-25(0.D. n1-1/4″( 32) PVC TUBE). DRAIN PUMP INCLUSION. RAISE IS MAX 33-7/16″(850mm) FROM THE CEILING.
  5. ELECTRICAL BOX MAY BE REMOVED FOR THE SERVICE PURPOSE. MAKE SURE TO SLACK THE ELECTRICAL WIRE LITTLE BIT FOR CONTROL/POWER WIRES CONNECTION.
  6. THE HEIGHT OF THE INDOOR UNIT IS ABLE TO BE ADJUSTED WITH THE GRILLE ATTACHED.
  7. REQUIRES “E” OR MORE SPACE BETWEEN TRANSOM AND CEILING FOR THE INSTALLATION.
  8. 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.)
  9. AS FOR NECESSARY INSTALLATION/SERVICE SPACE, PLEASE REFER TO THE RIGHT AT FIGURE
  10. FOR THE INSTALLATION OF THE OPTIONAL HIGH EFFICIENCY FILTER OR MULTIFUNCTIONAL CASEMENT, REFER TO SPECIAL DRAWING.
