Sorry, we couldn't find any existing installation instruction that matched.

Tank took too long to fill as the relief valve bled off air during fill cycle. Replacing relief valve fixed the problem.

Wrench set
Parts Used:
PS2020RV
Unplug compressor, release air and drain tank by loosening petcock. Unscrew solenoid cover, remove cover and set aside. Using a 9/16\" wrench, remove compression fitting at bottom of relief valve. Using a 1/2\" wrench and a 3/8\" deep socket, remove old relief valve from mount under solenoid cover. Discard old valve.

Install new relief, being careful that you do not over tighten. (Valve is soft brass and will snap if installed too tightly) Reconnect compression fitting at bottom of valve, reinstall solenoid cover, tighten petcock and start compressor and check for leaks.
