Hi guys.
I feel pretty stupid posting this, but I need advice please.
I have a Copeland model 8DHI-500X-BWM/D that has lost a large amount of it's oil charge. NOw, you'd think it would be simple to recharge, but no! There's oil sight glasses both sides of the sump, but no oil charge port.
On th eoil pump end, there are plugs either side of the oil pump that look like they may be fusible plugs.
Below, there are the internal PRV & the oil strainer.
The oil pump has one schrader connection to the high side. There is no external low-side connection on this model of compressor.
So the question is, where is the charging port?
My thoughts are either pump the compressor to atmospheric & then introduce the oil via the pump high side schrader, or via the compressor suction valve 1/4" port. I suspect that the former is out, as I'd need to force th epump into reverse, and I believe it's linked to the crank! And the latter I'm not over happy about as I do not know how easily the oil will flow through the suction, past the motor & into the sump.
Anyone done an oil change on these compressors? How do you introduce the new oil please?
A drawing can be found here: http://www.ecopeland.com/documentation.cfm?what=list2&prodtype=c&litbra=2&litdocid=20&sub=2&Famgrp=12 and click on the D8D compressor.
Thnaks for any help. :)
