In case the template gets separated from the base plate, abide by the directions written on the instructions to rejoin it to the base plate.

  6. For Elongated toilets, situate the bolt center with the word “ELONGATED” written on the base plate instructions. For round toilets, position the bolt center with the word “ROUND” written on the base plate prototype.
  7. Secure the base plate to the bidet toilet seat by tightly gripping the base plate with your hand to refrain it from shifting its position. Use a Phillips screwdriver to tauten the screws into the latex bushings. The bushings will magnify inside the escalating holes of the bidet seat. Pursue compression until the bolts are tight. Be vigilant not to over-tighten the bolts with unnecessary strength.
  8. If you intend to remove the base template, pull up the base plate gradually.
  9. Pedestal the Washlet by supporting the channels underneath the main body with the ruts on the base plate. Slither the main body onto the base plate. Continue doing so until it clicks.
  10. Scrutinize the alignment of the Washlet after the completion of the installation process.
  11. Press the rapid release button to disconnect the Washlet bidet seat and slide the main body forward.
  12. Stiffen the screws gradually until the base plate gets into contact with the bowl of the toilet.
