If you have a portable swamp cooler, make sure you drain the water outside and not inside your house. For window-mounted swamp coolers, you can leave it mounted in the window and let it drain outside the window. You may also choose to unmount it for maintenance and then put it back in the window.
Debris can get inside the water pan. This can cause blockages that stop up the cooler, and may lead to unclean water cycling through it.
When the time is up, drain the vinegar or soapy water into a bucket.
Check the pads every few months to look for cracks and overall poor condition.
Store the swamp cooler in a cool, dry area in the original carton.
