Re: I have a portable Honeywell Evap Cooler Tower where...
There are a couple of things to check. There is a water pump in the unit that draws the water and pushes it through a tube into the pad area. The tubes can get plugged or the motor on the pump can fail.

Make sure its on cooling not just on fresh air / vent setting. If the pads are not getting wet and the control is on cool fresh air, either A/ The machine is not filling with water or B/ The pump has failed.
I hope this helps. Note: the manual covers a few different models. You should ignore any section about the HCE323; that model has a remote and a few other extras.
Your unit may have a wall control which can set the Evap cooler to a pre fill mode time which fills the base with water then there is a pre wet mode which starts the pump to wet the pads. After both these functions have completed the fan will start. This could take up to 4 minutes before the fan starts and can be programmed out if not required.
Open the waterline tap valve or may have to clean small orifice
that is in line where 1/4" line meets humidifier. Need to shut water off
and in screw nut holding copoet line to humidifier
paula298, A new unit will take a while for the pad to become wet and more efficient. Remember, there may be two switches: fan and water pump. The unit must be full of water and the pump ON to work correctly.
If the unit has a water pump only setting, run the pump without the fan for about 20 minutes. That will get the pads nice and wet and you should get a good result. A rule of thumb in the desert is 20 to 25 degrees of cooling compared to the ambient air.
Don't use a cooler in closed area. The cooler will simply act like a room humidifier. Use in an open garage or porch for the best result.
Just found at least one problem with mine. I pulled off the back screen and then pulled off the back cover by undoing the two screws at the top. There is a pad in there that rotates through the water reservoir. If this pad doesn't get wet, you won't get any cooling. My pad was bone dry. Turns out the wire for the motor that rotates the pad was disconnected from the front control panel. I reconnected the wire and now the pad rotates through the water reservoir. We'll see how this works.
