Every spring when I prepare the cooler for another cooling season I have
to get rid of the dirt accumulated in the blower during the winter. What
I do is hold an A/C filter over the cooler air output and start the
motor. This catches most of the dirt. I have remember to do it for the
next ten startups or so, a PITA.
What the blower needs is a large hole on its side at the bottom so you
could flush it out with a hose. No hole in mine, anyhow.
How do you clean yours out?
Also, I often wonder where all that dirt comes from? The cooler is closed
up and the cooling pads should stop dust from getting inside in winter.
You know it's time to clean the refrigerator
when something closes the door from the inside.
By "blower", do you mean the cooler housing itself? Or, on the
blades of the squirrel cage?
If your cooler does NOT have separate wet and dry sections,
consider carefully hosing it down (inside)?
We just drained the sump every season and rinsed it clean again
Surely you jest? :> The fine dust (think haboob) gets in damn
near EVERYWHERE! During cooling season(s), water flowing through
the pads helps capture the dirt so it doesn't get onto things
(though the sump gets cruddy).
There's not a drain for the sump? How do you "winterize" it?
Some coolers have a sump (reservoir) that fills the entire bottom
of the cooler. This can be a side-draft or down-draft cooler
(in the case of down draft like this, there's a "hole" in the
center of the sump through which the air exits into the house;
so, the sump is sort of like a "moat" around a castle).
[The down-draft often has pads on all four sides -- pull more
air through the pads without needing a physically larger cooler
For a wet-dry cooler, the pad is usually on one side of the cooler
with the sump directly beneath. The blower is located in the
"dry" side -- drafting out the side or down.
[In theory, the blower isn't subjected to as much corrosive
effects -- and, you don't have to fear the "mote" springing a leak...
directly INTO your ductwork connected from below!]
Well, there's the Elizabeth -- which connects to the Becky... which,
in turn, feeds the Betsy Sue. Unless, of course, you've got a European
model (in which case, the parts are named Hilda, Gertrude and Hermione!)
If you don't have a drain (??), take the feed tube from the outlet of
the pump and disconnect it from the spider (the distribution pipe
at the top of the cooler, above the pads) -- I guess this would be
called Charlotte! :>
Run the pipe (usually flexible hose) out the side of the cooler.
Turn pump on (but not blower!) and direct a gentle, FOCUSED stream
of water at any accumulated dirt (a sponge can be helpful).
Just make sure you don't get ahead of the pump's ability to drain
the sump as you're busy flushing water through it!
