    digicool ak900 leaking hi side valve

    I was charging r410a liquid into the high side after evacuation, so I had it wide open my manifold was really cold just about frosty, after I close my hi side valve on the manifold i remove my common hose off the tank as its hanging I see my manifold start to ice up its bleeding through. has anyone had to replace the seals inside there ak900 yet???? im a little disappointed, it happened on my last call Friday maybe come Monday it had time to warm up and soften up to reseal. I think since it got so cold the gasket got hard and couldn't seal properly ill see.

    There is a Allen screw in each end. Tighten down on the high side one just a bit. Not much, maybe a quarter turn.

    This should take care of the issue.
