Routine Care & Maintenance Tips: Marvin Ultimate Casement & Ultimate Awning

Operation and Maintenance

The powerful single-arm operator is the mechanism that you crank to open and close the Ultimate Casement and Ultimate Awning. To operate the window, first unlock it by pushing the lock handle ‘up’. Crank the handle to open the window sash.

To lock the window, crank the window sash closed. Press down on the lock handle. The lock pulls the sash tightly against the weather strip and seals the window.

To keep your Casement or Awning operating smoothly, clean the window track occasionally with a dry brush. To help prevent the sash from sticking, apply a small amount of dry lubricant to the track (available at most home improvement stores) if necessary. Do not use oily lubricants.

Using the Wash-Mode Feature

The Ultimate Casement and Ultimate Replacement Casement feature a wash mode system which allows the entire window to be washed from inside the home.

Crank the handle a couple times. Push down on the arm and push the window away. The arm can be disconnected anywhere within the first 45 degrees of opening. Crank the arm back to the closed position.

Swing the window all the way open and pull it across toward the lock. You now have access to the exterior of the window.

Window Opening Control Device (Casement)

Marvin offers a factory applied Window Opening Control Device for crank-out Ultimate Casement Products. See the Marvin website for safety and operating information for this optional feature.
