Oh you mean RC and PC
They are in at the bottom out at the top.

Swap the rc around, the vapour enters from the bottom..

If you put the valves on the outlets, it puts the pump pressure into the condenser which helps with removing air bubbles/pockets, I run an additonal purge valve on the outlets with some clear tubing to bleed any air pockets out, the tubing lets me know if there is air there, makes setup much smoother when you know theres no trapped air.

I think scythe was talking the cooler tower, but i hadnt noticed your stills condenser connections before he mentioned it.

With the tower, What diameter of pipe are you connecting to with the garden hose on the top of the unit? The manifolds look like 19mm? Dose it neck down from that at all? If it's 10mm or under, you might have to do some bigger piping in there to get the flow rate up.

Oh and if you go to the rural irrigation section (usually next to copper/brass section) vs the garden irrigation section at big green shed, they sell better quality hose clamps cheaper in that isle

ah ok I haven't read that before always saw in at the bottom out at the top. I always assumed it was for the bleeding the air out and the heat rising out the pipe. Makes sense for the RC since its an upside down PC

ok I'll Remember that when I get it setup fully. It should work more efficiently if i can remove any more trapped air.

Yeah I thought he was talking about the cooling tower either way it may have helped. Once I can start measuring the temps I might even swap the way it runs in the cooling tower and see what happens.

13mm connectors and fittings through out, One manifold is 19mm other is 25mm. It splits up into 7x 10mm coils between the manifolds. Haven't measured my flow rate but looks pretty similar to how it ran through the T500 Alembic Pot with a 380L reservoir and short length of hose. I have the pump quite high and will be higher when I get it setup properly so will be less head(m) so will have slightly higher flow. at a guess id say its running at about 15L/m being that I run in summer for solar to cover my usage the water and air is always a decent temp so unless I force chill it with ice or something I cant really change the water temp if its getting cooled to the same temp it was.

Yeah it was a temp fix for cable ties just to get it all working. are you talking about metal hose clamps vs those plastic dripper fitting ones?

Yeah the metal worm gear ones like (used to be) on your car

The plastic irrigation ones work ok and i have used them a bit while im working out my plumbing (things keep changing lols), but on hot bits the SS ones would be much safer

15l/ min should be plenty but it will come down to heat soak at the end of a long run i recon
