If the outdoor temperature is below 35 degrees F:

After completing the refrigerant line connections, leak 

checking the system, and evacuating the indoor section 

and all line connections (using proper methods), perform 

the following steps:

1. Determine the recommended charge addition (if applicable) 

for the system being installed. This information is in the 

unit’s QRD (Quick Reference Data sheet).

2. Calculate the amount of additional refrigerant needed for 

the line set length of the actual installation. This information

Data sheet).

3. Weigh in the additional charge amounts determined by 

steps 1 and 2 above.

4. Return to the system when the outdoor temperature is 35 

degrees F or higher and follow the steps defined in step 4 

of the “If the outdoor temperature is between 35 degrees 

and 65 degrees F" or "If the outdoor temperature is 65
