Freshly fitted film needs a short settling period, so leave the windows up until your installer says otherwise; a little haze or a few small water pockets during that time are normal. After that, clean with a soft cloth and a gentle, non-abrasive cleaner, and keep scrapers, scouring pads and harsh solvents away from the inside of the glass. Your installer will give you the aftercare advice that applies to the film on your car. There is more general guidance here.
