ALL phases of this installation must comply with NATIONAL, STATE AND LOCAL CODES
IMPORTANT - This Document is customer property and is to remain with this unit. Please return to service informa-
tion pack upon completion of work.
These instructions do not cover all variations in systems or provide for every possible contingency to be met in connection with
the installation. Should further information be desired or should particular problems arise which are not covered sufficiently for the
purchaser's purposes, the matter should be referred to your installing dealer or local distributor.
Note: The manufacturer recommends installing only approved matched indoor and outdoor systems. Some of the benefits of
installing approved matched indoor and outdoor split systems are maximum efficiency, optimum performance and the best overall
system reliability.
Note: R-454B refrigerant is an "A2L" refrigerant meaning: A = non-toxic, 2 = flammable, L = low burning velocity.
The term "A2L" is used throughout this document.

Page 12: Section 14. System Charge Adjustment
Section 14. System Charge Adjustment 14.1 Temperature Measurements (Systems can be rated with TXV, EEV or Piston. Ensure charging method is correct). Important: Installer must mark/write the total refrigerant charge on the OD unit label after adjusting for indoor coil and lineset. Technicians must have their refrigerant cylinder on a scale during the charging procedure and measure how much additional refrigerant is put in the system (additional over the factory charge). - Page 13 STEP 2 - Determine the final subcooling target using total Line Length and Lift measured in STEP 1 and the charts below. 018 & 030 Models 024, 036 & 042 Models SUBCOOL CHARGING CHART CORRECTIONS TABLE (FOR LINE LENGTH AND RISE) SUBCOOL CHARGING CHART CORRECTIONS TABLE (FOR LINE LENGTH AND RISE) 1°...
