When a multizone Breeze33 (generation 1) system is installed, sometimes additional refrigerant must be added. Multizone Breeze33 outdoor units are pre-charged for a line set length of 24.5 ft for each of the zones it can handle. (A 2-zone unit is pre-charged for 49 ft, a 3-zone system is pre-charged for 73.5 ft, etc) If the total amount of line sets is longer than what is allotted for the pre-charge, additional refrigerant must be added. Please see below on how to calculate the correct amount of additional refrigerant.
NOTE: The maximum line set length for each system is listed on each product’s spec sheet. These spec sheets can be found at Breeze33.com/resources.
