As we transition to the more efficient 22-21 SEER Multi Splits, please pardon our dust as we rebuild this wiki page to reflect our new units. All information on the 16 SEER units are now under the Legacy Support menu. Thank you.


This is the support page for the 22-21 SEER Air-Con Multi Split line. If you're looking for our 16 SEER models please visit the Air-Con Multi Split 16 SEER page.

  • Note: Each indoor unit combination is viewed as a column.
  • Note: Both quad zone outdoor units are capable of the same combinations but make your judgement on the correct one to use based on room size.
  • Note: There are more possible combinations than those listed above. Please use proper capacity judgment when making multi-split combinations.
