How to Operate & Clean Your Tilt-n-Lock Window

Can’t tell which side of your window that smudge is on? When you own a Viwinco window with Tilt-n-Lock, you can easily clean both sides from inside your home! Viwinco’s patented Tilt-n-Lock technology allows users to unlock, lift, tilt and lock all with a single hand to make cleaning a breeze. Simple, one-handed use is the name of the game.  

1. Unlock the Window & Lift The Sash 

First, locate the Tilt-n-Lock latch (between the top and bottom sashes).

The latch should be at 0 degrees, as pictured. 

At this stage, the tilt latches are engaged into the window jambs. Turn it 150 degrees to the right, matching the following picture: 

The sash is now unlocked, but the tilt latches are still engaged in the jambs. Lift the window vertically, but do not attempt to tilt.  

2. Tilt-In the Bottom Sash  

Raise the bottom sash a few inches above the sill before tilting.

Push the Tilt-n-Lock handle to the 180-degree position to disengage the hidden tilt latches from the jambs, as pictured:   

Tilt the sash inward until it is fully open and resting securely (it will not fall out). If you have an Impact window, be aware that the sash will be heavier due to the impact-resistant glass.  

3. Open the Top Sash (Double-Hung Products Only)  

Once the bottom sash is secure, lower the top sash slightly, leaving a few inches of space between the two sashes. Press the two thumb latches inward to disengage the tilt locks, then gently tilt the top sash inward toward you.

4. Cleaning  

With the sash, or sashes, tilted in, you may now clean your windows with ease. Use a window cleanser and a soft cloth to ensure streak-free, beautiful glass.  

5. Closing Your Window  

For Single-Hung Windows: 

Tilt the bottom sash back into place and press it firmly until it clicks securely into place. Turn the Tilt-n-Lock handle back to 0 degrees, locking it 

For Double-Hung Windows: 

  1. Once you’ve finished cleaning the top sash, tilt it back into the frame and push it up until it is fully seated at the top of the window frame.
  2. Make sure the top sash is completely raised. If it isn’t, the lock may not align properly, making it difficult to secure the window.    
  3. Tilt the bottom sash back into place and press it firmly until it clicks securely into place. Turn the Tilt-n-Lock handle back to 0 degrees, locking it. 

Troubleshooting Tips  

  • If the sash does not tilt inward, double-check that the Tilt-n-Lock handle is fully in the 180° position before attempting to tilt. 
  • If the window does not lock properly, ensure the sash is completely seated in the frame and the handle is rotated fully back to 0°. 
  • For windows that are 36” or wider, they will have two locks: a cam lock on the left and a Tilt-n-Lock on the right, which is used to open and close the window. The same instructions apply to these wider windows.
