High efficiency dual flush toilet
• Observe all local plumbing and building codes.
• Carefully inspect the new toilet and components for damage.
• If the existing toilet installation area does not have a supply shut-off valve (see
Fig. 9) below the tank, you will need to install one before installing the new toilet.
• Ceramic toilets are very fragile, so please handle your new toilet with extra care
during installation.
• Once the toilet is removed from the packaging, always ensure it is placed on a
soft surface such as a towel or blanket before installation.
Tools required for assembly: safety goggles, hacksaw,
level, putty knife, adjustable wrench.
1. Check to make sure that the top surface of the floor
flange (see Fig. 1) is above the plane of the floor surface
on which the bowl will be installed. If the floor flange is
below the floor surface due to any reason (i.e. marble or
ceramic tiles, or improper installation, etc.), then you will
have to put on the outlet seal “I” (see Fig. 2) that is thick
enough to create a proper seal.
Note:
A professional plumber is recommended for this
type of installation.
2. Turn the toilet bowl upside-down and rest it gently on the
floor on something soft (i.e. a towel or piece of
cardboard). Then center the wax side of the outlet seal “I”
over the toilet bowl outlet and firmly push it down around
the bowl outlet (see Fig. 2).
3. Place floor flange bolts “AA” in floor flange, securing
them in place with the disk nuts “BB” to hold them in
place while installing the bowl (see Fig. 3).
4. Lift the toilet bowl, turning it right-side up, and lower it
over the floor flange while having the floor flange bolts
“AA” come through the floor mounting holes of the bowl.
Then firmly push down and twist the toilet bowl until it is
touching the floor and ensuring a proper seal of the toilet
bowl outlet with the floor flange. Be careful not to
damage the floor around the bottom of the toilet bowl
(see Fig. 4).
5. If required, place shims (not supplied) under the base of
the toilet bowl to prevent any rocking of the toilet bowl on
the floor (see Fig. 5b). On both sides of the bowl, place
the bolt cap bases “H”, floor flange bolt washers “DD”,
and the floor flange nuts “CC” onto the floor flange bolts
“AA”. Alternately tighten the floor flange nuts “CC” by a
couple of turns each until snug. DO NOT OVER TIGHTEN.
Snap the bolt cap “G” onto the bolt cap base “H” (see
Fig. 5a).
Note:
If the floor flange bolts “AA” are too long, then cut
the top of the bolt with a hacksaw to make room for the
bolt cap to snap into place (be careful not to damage the
ceramic while cutting). If desired, place a bead of
caulking (not supplies) around the base of the toilet bowl
where it contacts the floor (see Fig. 5b).
6. Turn the toilet tank upside-down and rest it gently on the
floor on something soft (i.e. a towel or piece of
cardboard). Install the tank gasket “K” over the bottom
threads of the flush valve, making sure that the tank
gasket “K” covers the flush valve nut (see Fig. 5c).
7. Lift the toilet tank, turning it right-side up, and place
the tank onto the back of the top of the toilet bowl,
lining up the 2 tank mounting holes. On both sides of
the tank, install the tank bolts “GG”, inside tank
rubber washers “HH”, outside tank rubber washers
“II”, outside tank metal washers “JJ”, and bolt nuts
“KK”. Tighten bolts alternately by a couple of turns
each, until the ceramic bottom of the tank is just
about to touch the top of the ceramic ribs on the top
of the bowl (
note:
it may be necessary to push down
on the inside bottom of the tank to make the
tightening easier). DO NOT OVER TIGHTEN (see Fig.
5d).
8. DUAL FLUSH BUTTON INSTALLATION
(i) Push button installation: The dual flush button mechanism will be shipped inside the
tank in a separate plastic bag and will need to be installed on the tank cover. Open
bag and carefully remove contents.
• Insert button mechanism through tank lid (see Fig. 6). The buttons should be
rotated so the smaller button is on the left.
• Securely tighten nut. DO NOT OVER TIGHTEN.
(ii) Push rod adjustment: To ensure both buttons flush the toilet correctly, the bottom of
each push rod must be flush with the top surface area of the flush valve cylinders. If the
rods are not flush with the top surface, adjust the length of each rod by turning the
adjustment nut on each push rod (see Fig. 7).
DUAL FLUSH VALVE TROUBLESHOOTING
Flush volume
If the push rods are too short and not fully connecting with the flush valves, this may
result in low flush volume. Readjust push rod height and ensure the bottom of the push
rod is flush with top surface of the valve cylinder (see instruction ii, Fig. 7).
Flush valve leaking
If the push rods are too long, this may result in the flush valve leaking. Shorten push
rods with the adjustment nuts (see instruction ii, Fig. 7).
Tank leaking from the valve (and for maintenance and cleaning)
To clean the valve seal or replace the entire unit:
• Turn cylinder counter clockwise and lift off
• Clean the bottom of the flush valve seal and the top of the flush valve seat
• Reverse this procedure to attach flush valve cylinder (see Fig. 8)
