Installation Tips for Ultraloq U-Bolt Series:
Note: ANY WRONG STEP WILL LEAD TO THE WHOLE INSTALLATION ALL FAILED.
- Make sure the cylinder tailpiece is adaptive for the thickness of the door. After installing the cover plate, 2 pieces over the Assembly Mounting Plate hole is best. More than 3 pieces, the lock will have the Jamming, and the motor is working overload.
- Please DON'T insert the mechanical key during the whole installation.
- Keep the Bolt shrink and the cylinder tailpiece horizontal.
- Keep the knob of the U-Bolt in the Unlock position.
