404a pressures in low

[steve wright]

I also have a 10 degree superheat where the liquid from the accumulator passes across the suction line, not sure what it's called but thought I would mention it.

Are you saying you have less superheat after the heat exchanger? Colder at the outlet of heat exchanger than the inlet?

What charging procedure did you use with this unit?

Units with low ambient control valves require a specific charging procedure to ensure the proper charge.




Explain. This would tend to cause the opposite problem, wouldn't you think?

I was talking about the possible reason for someone trying to adjust the Valve in the first place. Sorry for the confusion.

If adding or reclaiming 404, may be "off" cause its a blend??
