Install them on high points in the system, where air tends to accumulate.
In order to remove air from horizontal pipes, install AO-2 "air out", which will slow the flow velocity and effectively separate air.
We recommend TA-16CVA and TA-16CVS air vents, which do not inhale air if pressure at the inlet side becomes negative.
No, they cannot. They might inhale air but the performance cannot be guaranteed.
It is to introduce air into the valve smoothly.
Yes, they can.
Valve and valve seat might be jammed by debris. Please service the valve according to the manual.
Yes, no problem.
Please use TA-16CV series with check valve.
Lead the outlet to a drain ditch in case water leaks.
