Please explain where the sitch should be in the summer either up or down. Thanks

Fan should blow down in summer, and up in winter(thats what they say)? The switch is not always down for down.
Sometimes when switch is down fan blows up.
Fan direction important, not switch position.

Fan should always run counter clockwise in the summer.
