QUESTIONS & ANSWERSAsk a Question
If I have a triple zone mini split and already have two 9000 btu heads at 25ft each. I realize the outside unit comes precharged for only 75ft total of line. But can I add the 3rd head at 50ft from outside and add more coolant from a certified A/C tech, will that work?
Yes, that would be completely fine to do.
what gauge is the control wire?
Does this line set fit 9000BTU 3/4ton 19.5 SEER? Model WYS009AMFI19RL-16
For 9,000 BTU 19.5 SEER you would need to select the 1/4"-3/8" diameter option.
What are the sizes of the flare nuts on the ends of these copper line sets? That way I know what wrenches I need to purchase for my torque wrench
Piping Diameter vs. Flare Nut Size:
1/4" = 5/8"
3/8" = 13/16"
1/2" = 15/16"
5/8" = 1-1/16"
