I have an Alpine RW3000G evaporative cooler for the garage, and the pads were getting pretty bogged down with mineral deposits. They were changed out the pads a couple of months ago at the beginning of the summer, but it was definitely time for a new set.

The tools and materials used for the removal and installation of the evaporative cooler pads are:
- Pair of pliers
- Utility knife
- Replacement pad material (either aspen or synthetic)

First thing is to shut off the water going to the cooler. I did this because I planned on draining the existing water out of the system.
Next the panels holding the pads in place were removed.

Window Cooler Ready To Disassemble
For the Alpine unit I have, removing the pads from the window coolers starts with unhooking the top holder.

Pliers are used to remove the lower pad holders. I found it necessary sometimes to slightly bend the wire closer to 90 degrees to get these off.
Unhooking Bottom Holder
When cutting the new pads, I just used the one of the old ones as a template for the three new ones.
Cutting New Pads
Just before installing the new pads in the windows was as good a time as any to drain the old water from the system. Loosening the restraining nut from the bottom of the overflow drain was the only thing necessary to remove it.

The newly cut pads were reinstalled into the window coolers by just reversing the steps. These were placed back into the swamp cooler except for one, which allowed for installing the overflow drain.
The overflow drain was reinstalled once the water was drained out.
The water was turned back on to fill the system’s reservoir back up.

Once filled, scale guard was added to help prevent scaling and mineral build up on the pads.
The last pad holder was installed, and the system was turned on for testing.
