WHAT IS

CEFIONTECT®?

CEFIONTECT® MAINTENANCE INSTRUCTIONS

CEFIONTECT® glaze is TOTO’s patented super-smooth permanent

glazing that prevents debris from sticking to surfaces.

Toilets and lavatories are made of ceramic – a porous material that allows

mold and particles to stick to the surface creating stains, scaling and

build-up.

CEFIONTECT® glaze, along with regular cleaning, will keep your TOTO

products in pristine condition.

NOTE:

For regular cleaning of your TOTO product with CEFIONTECT®:

• Use a mild dish detergent to clean your lavatory.

• Use a gel-based toilet bowl cleaner.

• Use a soft cloth to clean your lavatory.

• Use a soft-bristled plastic brush to clean your toilet.

• Don’t use cleanser, polishing powders or detergents that

have gritty or coarse particles.

• Don’t use bleach, chemical thinners, or products that include

acid or alkaline detergents in their ingredients.

• Don’t use metal scrub brushes or steel wool.

Following these cleaning instructions will ensure that the CEFIONTECT®

glaze on your product will remain intact, keeping your TOTO product

beautiful for years to come.

BEFORE INSTALLATION

Read these instructions thoroughly before beginning work.

Please leave instructions for customers. These instructions contain

maintenance and warranty information.

If necessary, remove the existing toilet and if new construction, purge the

supply line.

Due to the powerful performance of our Tornado, G-Max, E-Max and Power

Gravity ushing systems, they are not specied for back-to-back installations.

The only means of installing these toilets in a back-to-back situation is when

the toilet drain connections incorporate a WYE tting. Please contact your

builder or contractor prior to this installation.

Make sure that the ll valve does not turn and

hit the tank while tightening.

8. Connect the water supply hose to the ll valve threads as

seen at the bottom of toilet tank (Ill. 7). Tighten this

connection ﬁnger tight.

The water supply hose must be connected

to the ll valve BEFORE the tank-to-bowl

installation. TOTO recommends using a

longer exible supply hose.

5. Install the side screws to the mounting blocks.

Cover the screw head with the provided screw

caps (ill. 4).

6. Install the tank-to-bowl mounting hardware to

the tank (ill. 5). Lay the tank down on its back.

Place a rubber washer onto a bolt. Reach

inside the tank and position the bolt through

one of the holes in the bottom of the tank. On

the outside of the tank, place a metal washer

and nut onto the bolt. Hold the bolt centered

in the hole and tighten the nut ﬁnger tight. Turn

the nut an additional 1/2 turn with a wrench.

Repeat this process for the remaining hole in

the tank.

Do NOT overtighten hardware,

as it may break the china and

cause personal injury or property

damage.

7. Place the tank upside down onto some

padding. Inspect the smaller ll valve nut and

larger ush valve nut for a secure connection

(ill. 6). Try to tighten the nuts with your hands.

If loose, tighten the nut hand tight and an

additional 1/4 turn for the smaller ll valve nut

and an additional 1/2 turn for the larger ush

tower nut.

9. Place the tank-to-bowl gasket onto the ush

tower nut (ill. 8). While pressing down, spread the

gasket over the nut until the gasket touches the

bottom of the tank. A slight gap between the

tank bottom and the gasket is allowable.

10. Pick up the tank and carefully guide the

water supply hose into the bowl’s ll valve

hole, align the tank-to-bowl gasket over the

inlet of the bowl, and align the tank bolts

over the bolt holes of the bowl. (ill.9)

11. Using provided hand-tight nuts, hand

tighten the nuts evenly until tank sets

snugly on each of the 3 contact points

on the bowl (ill. 10). Do not overtighten.

Overtightening may break the china and

cause personal injury and/or property

damage.

12. Flush the water supply line for a few

seconds to remove any debris that may

enter the new ﬁll valve. (For new home

constructions and/or additions, ﬂush the

water supply line for more than a minute to

help remove any residual PVC adhesives,

solder ﬂux, and/ or pipe sealants that were

used for the new plumbing.)

13. Install the exible water supply hose to the

angle stop (ill. 11). Make sure that the hose

is free of kinks.

14. Carefully place the lid on top of the tank.

NOTE: The water supply pressure should

be 20 to 80 psi static.

15. Flush toilet a few times to check for issues

and leaks. Make sure NO WATER LEAK on

bowl and tank.

CAUTION: Avoid using a wrench to tighten

the connection as you may damage the

plastic threads and/or cause the ﬁll valve to

rotate inside the tank.

valve. Remove the old ll valve.

2. Install new ll valve by sliding the threaded portion

of the shaft through the hole in the bottom of tank.

end of the ll valve. Use a athead screwdriver to

make adjustments:

• To raise the water level: turn the screwdriver

clockwise, or towards the ‘+’ indicator.

• To lower the water level: turn the screwdriver

counter-clockwise, or towards the ‘-’

indicator.

CARE AND CLEANING

DO NOT USE IN-TANK BOWL CLEANERS.

The use of high concentration of chlorine or chlorine-related products can

seriously damage ttings in the tank. This damage can cause leakage and

property damage. TOTO shall not be responsible or liable for any tank tting

failure or damage caused by the use of in-tank bowl cleaners.

NOTICE

Use a detergent or non-abrasive toilet cleaner and a soft bristled

plastic brush to clean your toilet. To remove hard water stains, use

vinegar or lime dissolving cleaner and a non-scratch scour pad made

for porcelain. Allow a little contact time to allow the cleaner to dis-

solve the buildup.

Do not over-tighten.

4. Connect the water supply (Ill. 1). Pipe dope is not recommended. Attach the

rell tube to the ll valve and clip the other end to the overow pipe.
