If you were sent off for anything other than for 2 cautions or for foul and abusive language, you have 2 working days to submit an appeal through Whole Game, for example,  if you are sent off on a Sunday, you have until Tuesday night to confirm your intention to appeal. Anything over this time will not be considered and the dismissal will stand. You will then have a further 2 days to submit any evidence to Manchester FA in support of the appeal. The appeal will then be heard before the suspension begins, and the club will be informed of the result at the earliest opportunity.
