In need of a Coleman swamp cooler manual

Here is a photo of the unit, if you look at the roof air unit it sure looks like a normal AC unit but it's swamp cooler.

I did pull off the trim pieces and see the tank and on the outside just underneath the shroud I see 2 3/8 hoses poking out.

If your wondering why I'm guting this trailer I am making a ham shack out of it.

does it look like this one

the one I had years ago, the fan was direct drive, NO BELT

it did hold several gallons of water, and was suggested to use only while parked

it had a float valve in it, and could be connected to the RV water system
using small clear tubing on the exterior of the RV , up to roof

turn on pump, fill evap cooler, turn off pump, refill as needed

drain before moving

the filter would get dirty from the dust drawn in, being filtered and the foam filter was wet, like the mat in a residential evap unit

fan pulled about 4 amps at 12v, 48~60w vs 1400w for 120v roof A/C

Not much to a evaporative cooler.
Power source
Fan motor....check belt--should deflective roughly 3/4". A few drops of oil if bearings have oil caps
Fan..clean, rotates freely & oil if it has oil caps
Pump.....suction screen clear. Water flows thru dispersing tubing onto drip trays and soaks pads
Sufficient water level.....check routinely due to 'manual' supply

Roof installation with manual water..I'd pickup a float valve and install it with soft copper tubing water supply line and install an over flow tube with garden hose connected to drain off to ground VS manually adding water.
Those items available at Home Depot/Lowes/ACE

Old swamp cooler trick........and it works
Drop a bar of IVORY Soap in water. It helps with odor, lubes pump and helps wet pads.

Should do well up there in the high desert.
Lived in Baldy Mesa and only used swamp cooler for house

Just installed one couple weeks ago in current home....house is well insulated (6" walls) and can get temp down to 68*F (85*F outside) course the humidity is about 3%

Here is the manufacturers site, with all sorts of info plus contact info to e-mail them directly. You will need the model number or at least the unit name.
