Tilt the bottom sash as described in the previous section. When the sash is in a horizontal position, lift both sides of the sash upward 2”- 3” (51-76 mm) raising pivot pins out of each clutch. Now rotate the sash until pivot pins clear the jambs and remove the bottom sash from the frame. Next, tilt the top sash using the same technique described in the previous section. When the sash is in a horizontal position, lift both sides upward 2”-3” (51-76 mm) raising pivot pins out of the clutch. Finally rotate the sash until the pivot pins clear the jambs and remove the top sash from the frame.

Hold the sash exterior side up with the top rail facing towards you.Rotate and insert the sash so the sash pins clear the frame and place it so the lower sash pin is 2”-4” (51-76 mm) above the clutch. Rotate the sash to the horizontal position and lower it down until the pivot pins are fully seated into the clutches. Simultaneously pull in on both tilt latches and tilt the sash up into place. Release the tilt latches and operate the sash to ensure that the sash is operating smoothly. Replace the bottom sash following the same procedure, except fully engage the tilt lever prior to lifting the bottom sash into place.

Some significant differences between the Magnum and other Marvin Double Hung windows are higher performance ratings and availability of very large double and single hung windows. Another difference is that when opening the Magnum window it will stop before it reaches the fully open position. Contact your local Marvin dealer for detailed instructions on how to safely tilt and/or remove the sash.
