chargeing with 404a

[cannedheat]

is it ok to charge walk in freezer to full sight glass . no receiver water cooled condenser

Should have a receiver if you have a tx valve.

Should have a receiver if you have a tx valve.

Not if it's not a pumpdown. Might just be using a t-stat to control compressor. A clear glass would be a starting point. SC & SH would be the proper way to go. Make sure the water regulating valve is set properly.

cycles on liquid line solinoid valve.compressor took a poop, was called to change out. copeland copelematic m. nrdi 031a tcf 800. going to change oil to ester before install. as well as ll drier and contactor. noticed someone has added suction drier canister with one core.no idea on history,not to familiar with low temp systems. thats why im asking about the charge.thanks

No receiver ??

Is this condenser indoor on top of freezer ?

[2sac]

You've got a receiver. Check under the condensing unit

[halsaydah]

Yeaa full sight glass is a good start but then after you notice the bubbles just starting to disappear, start doing SH and SC. You don't want to over charge..

[MicahWes]

Yeah, I bet there is a receiver under the unit.

[Phase Loss]

I bet the condenser is also the receiver.

looks like discharge line off compressor goes to vessel under compressor then liquid line exits vessel to drier and sight glass then to evap to freezer. vessel has water line going into it with water regulater. regulator has cap tube that senses pressure via discharge port, then another line exiting vessel dumping water to open sight drain. dont see any receiver.

have picture on iphone not sure how to post sorry

Someone correct me if I am wrong, but I believe based on the description this is a shell and coil type water cooled condenser and that the shell doubles as a receiver in this setup?

[cannedheat]

so the reciever is the vessel and the condenser water is basicly a coil in the vessel condensing hot gas into liquid and storage before entering liquid line and so on..
