charging 404a system

[cannedheat]

when charging a walk in freezer, is it ok to charge to a full sight glass. there isnt a receiver. 404a.

If the SC looks good and the glass is still flashing, stop charging. You are more concerned with the SC than the sight glass.

I've been told by my more learned colleauges that a system with txv and no reciever is pretty sensitive to charge. If it's not in right temp area. Charge'til it almost no flash. When close in themp it will stop flash and become clean sight glass. This is what i've performed on a pair of coolmax freezer units w/no reciever. Success every time. Ah... Subcool... let it be 'bout 5-6degF

No receiver, that could be a problem when it satisfies and pumps down. It does pump down, right?

That would depend on a number of factors.

Length of the liquid line being pumped down would be the biggest.

Walk in freezer with no receiver? Flashing sight glass is OK? Umm no!! TXV must have full colum of liquid. You cannot adjust TXV to proper superheat with out a full colum of liquid feeding it. It will hunt and never stabilize. Are you sure there is not a receiver?

Very bold statement to be making.

Got proof?

[rmitch78]

well, companies that use sporlan and danfoss told us that's why manufacturers are *trying* to do away with them on their systems. maybe not weed out the suckers like i mis-spoke, but to try to differ people from relying on them i should have said.
