any advice, tips and tricks, and all the like would be sincerely appreciated…
I work with a “Rainier” from OSS and recently i have ran into a pickle with what i think to be are clogged lines. For years prior to 2018 i ran a upright standing Terp style extractor with the material columns sitting on top of collection base, a MKIII to be exact. During my time w/ that system i never ran into issues regarding clogging but, after i made the upgrade and switch over to the Rainier w/ dual columns connecting the 12" collection with 3/8" lines, up until recently in the last 3-4 months i haven’t had any issues.
a brief description of my problem --> with having the system vac’d down and ready for injection, i open the tank and begin to flood columns with bottom valves closed. the columns fill up and as expected i open valves and dump into collection as it should happen… my recent issue, and my problem tonight… when i opened valves after flooding, nothing came out but tiny loogie sized portions…thankfully tonight i had only flooded 1 of the 2 columns so i was able to warm up column with jacket using warm water and move solvent up into the other column passively to be recovered…
i would think i could clean out the lines and polish off the interior by shooting clean solvent through and recovering as i normally would, which i have done once before and usually do when i fill the RC tank bi-weekly… BUT if a full columns worth of solvent (~11#) won’t dump into the collection; aside from taking apart the lines to soak overnight and clean with iso which i have already done this evening… how else would you deeter this problem in the future? how would i correct this issue?
regular weekly flushes with clean solvent? N2 assist to push lingering gas/oil from columns/lines into collection?
i have also be struggling to find a method to keep my pour spout clean after pours, as well as the ease of using a pour spout… i understand if you leave more solvent in the solution you will have less “left overs” but inevitably there is still oil left… is it just me being new and unfamiliar to the system or are there just some obstacles that will never be excused?
im in dire need of some advice and some help to push me in the right direction… anyone who has worked with, or currently works with the rainier or other like systems with lines connecting multiple spools who have any useful and beneficial pointers would be a saint to me.
i greatly appreciate the good looks!
