Installation Procedure (continued)
7) Install the side screws to the mounting blocks. Cover the screw head with the provided screw-cap (see Ill. 6).
  IMPORTANT: If the side screw does not engage the mounting blocks, then either the 
toilet bowl is not fully inserted in the socket or the mounting block is not installed prop-
erly. 
If the toilet is not installed properly, it may slide out of socket or leak. Please ensure that 
both sides are properly fitted and secure. Be sure not to over-tighten the screws, as it may 
results in product damage.
CAUTION

8) Connect the water supply hose to the fill valve. The water supply hose must 
be connected to the fill valve BEFORE the tank-to-bowl installation. TOTO 
recommends using a flexible supply hose (see Ill. 7). 
Please be sure to connect the water supply hose to the fill 
valve before installing the tank to the bowl. If procedure is 
reversed, the water supply installation may be impossible.
FAILURE TO FOLLOW THIS INSTRUCTION MAY RESULT IN 
PERSONAL INJURY AND/OR PROPERTY DAMAGE.

9) Install the tank-to-bowl gasket over the flush valve outlet on underside of the 
tank (see Ill. 8). 
 Pick up the tank and carefully guide the flush valve hose into the bowl inlet 
hole on the bowl tank-shelf. Make sure the bolts on the bowl fit through the 
opening in the base of the tank.
10) For easy assembly, remove the top-portion of the flush valve by disconnecting 
the refill tube. Turn the upper portion of the flush valve counter-clockwise, and 
pull it up (see Ill. 9). Insert the rubber washer then metal washer on the mount-
ing bolt. Thread on the nuts, hand-tighten before releasing the tank. Tighten 
the nuts evenly until tank sets snugly on each of the three contact points on 
the bowl. Re-install flush valve and refill tube.
