* Please note that a water strainer is required for each condensing unit model and now must be field supplied (strainer specification = 50 mesh).
** Application rules apply below 48°F. Please contact your local Daikin office for design assistance and approval.
*** The minimum cooling EWT is 34°F when the condensing unit is located below the indoor units.
