Installation Instructions
Clean the inside of the RUBNS-OLC with cleaning cloth and alcohol fluids until the inside is
clean without dust;
Connect the pointed plastic mouth to the body of RTV silicone rubber adhesive bottle. Seeillustration 1 above.
Smear RTV silicone rubber adhesive all over the concave channel of the RUBNS-OLC
uniformly as showed in illustration 2 above
Uniformly smear the two flat fringes of the concave channel with RTV silicone
rubber adhesive as the illustration 3 shows
Connect the bulging part of the RUBNS-OLC on one side into the concave channel of the
other side and squeeze the connecting part from one end to the other as illustration 4 indicates
