Height of lineset
Height is one thing(1/2 psi),tubing length is another (upto 3psi), LLFD is another(1 psi), elbows & fittings is still another( ???), LL Solenoid Valve is also figured (1psi). The pressure access fitting will give you what resistance you actually have. And the SGMI will let you see the SubCooling. PaulS w/ a picture of the T and SGMI, I will send you both. Don't forget the two press readings.0 -
Sub Cooling
In residential applications, until you can obtain the manufacturer's data, you most likely are safe with 10 degrees.0
