Just finished my lineset (52ft)run.
To my Fujitsu 18rflcd.
I currently have 200psi of nitrogen and have been holding @ 200psi for the last 2 hours.
Do I need to get the psi higher? Didnt want to add too much and risk damage.
No where in the the install manual does it talk about nitrogren pressure test buy rather using the vacuum procedure with a micron gauge to check for leaks.
I am in no rush so I planned on leaving it overnight anyway. I did test for bubbles. I thought I saw one at the inside 1/2″ flare connection but perhaps it was my OCD. If pressure holds then no leaks right??
Single vacuum or triple vacuum tomorrow? Any thoughts on that?
