ok,
got my 32,500btu mr slim online last dec.
by april something was wrong?
I took a few weeks break in the room
when it went back online with all 6000w fired up
no matter what the set temp was, room temps were in the hi 90s
big trouble.
this is what happened....
i did some repotting for the next bloom run in the room
and wet the promix/FFOF to keeep the dust down,
but not enuff i guess.
when i fired up the ac for the next round and potted more plants i noticed it didn't seem to cool as much
it went downhill quickly form that point and no matter the setting i was pushing hi 80s.
I checked the filters, dust had clogged the filters, but it didn't seem like that much.
BUT
it was enuff to affect the system trying to cool 6KW of heat,
the filters looked *kinda dirty* to me so i cleaned em and BAM, it cooled perfectly
those filters have to be kept---> CLEAN! even the users manual says to clean every 2wks
efficiency goes strait downhill when they start getting dirty *especially* with multi-1000w barebulb gro situation.
end of story, happy ending yeah yeah yeah.....
or so I thought
ok, here's the rest of this story.
i added another 24Kbtu mini for back up insurance.
but noticed my the fuggin mitsu mini was not cooling again 3-4wks later.
checked the filters but they were clean, every 2wks they get vac'd...?
crap!! what NOW?
checking everything, I should have been AOK,
but it was cooling less than when the filters were clogged.
so now I'm thinking i have to call HVAC
and check r410 level etc etc.while my 24,000btu mini is trying to cover the job of a 32,500btu
about to call hvac when i noticed something looking like ash blowing out the unit, not much,
hardly noticable,
i had been seeing it on the floor occasionally and wondered what it was and where it came from
checking inside the head unit I found this coating the inline blower assembly
.
mold was choking 80% of the airflow on the inline blowers fan blades!
reading further, like i should have the manual sez filters getting clogged can create a mold situation,
and also shutting down the unit
and not getting all the water out of the water collection tray below the fan will also contribute.s
o when i went off line in april with water in the tray
and with the dirty filter it looks like mold got a foothold and started growing on the fan blades,
then i started a new bloom run with my Rh 65-70% for the 1st 3whks of bloom then lower it as buds bulk up.
those 3 wks of Hi Rh were perfect for the mold and it took off and clogged up the fan blades.
now i have to bomb the room with trinity fungicide and spray eagle 20 on the plants i put into bloom a few days ago.
so anyways going online and found the service manual to see what it takes to remove the inline fan,
christ you have to pull everything apart to get it out.
called tech support before reading the service manual and while waiting I read all this crap i had to do to get the blower out.
he came on said screw the service manual
he could walk me thru it and have it out in 5 min with a phillips screwdriver
he was true to his word
keep your filters clean!! and if you have to service the unit yourself call tech support.
they turned a whole day job into a few hours.
I hope this helps another IC brother with their mini split down the road in the future
