How to restart sprite animations in the script

Hello, I want to play a sprite animation, several times during a game level. It does the job well for the first time but for the second time, it does not start from the first frame. How can I reset the animation to frame 0 after the first play.

By the way, as far as I understand, 'Animation' does not support sprite animations. It only can be used for 3d objects. Am I correct?

Thank you for your help in advance,

 void Update () 
 {
         if (SOMETHING == true)
         {
             //Start sprite animation from frame 0 ???
              anim.SetBool("myAnimation", true);    
             StartCoroutine (timer());    
         }
 }

       IEnumerator timer()
     {
           yield return new WaitForSeconds (2);
     }
 }
