To open the Milgard vinyl double-hung window lift up on the smart touch lock and slide open the bottom sash.  The window sashes can tilt inward.  First locate the two tilt latches on the top of the bottom sash.  Slide the latches toward the center and pull towards you to disengage the sash from the window frame.  Now pull downward on the upper sash pull rail until the upper sash is about six inches above the open bottom sash.  Slide the tilt latches inward and pull the sash towards you.  You may rest the top sash on the open bottom sash.

To close rotate the upper sash until the tilt latches click back into the track. Push the upper sash up until it stops in a closed position. (Please note: Do not pull inward while closing, this might prevent the locks from engaging properly)The top sash must be fully seated in the track for the window lock to engage properly.  Now rotate the bottom sash until both latches engage in the track.  Close the bottom sash by pulling down until the lock engages.  When the window is closed, it’s locked.
