NEOREST® Installation Instructions <Bowl>
The installation of the toilet bowl for the NEOREST® differs from installation
of conventional toilet bowls. Be sure to read the following installation
instructions and install the product only as described in this manual.
✲ Before installation, confirm that the parts listed below are included in the
kit.
Before installing the NEOREST
®
, be sure to read the safety instructions in
"Always Follow This Precaution" and install the product only as described
in the instructions. Precautionary symbols are used in these instructions to
ensure safe and proper installation of the product and to prevent injury to
the end-user and damage to personal property. The definitions of these
precautionary symbols are as follows.
■ Confirm that there is enough floor space to install the toilet unit and
that the bathroom door will open/close without obstruction.
■ Confirm that the position of the drain hole and pipes are properly lined
up as designated in the drawing.
■ Water Pressure.
The NEOREST
®
is designed to operate under a minimum working
pressure of 10 psi flowing. It should be noted that the standard range of
working pressure allowed by model codes is 20 to 80 psi static.*
It is necessary to install the water shutoff valve (angle stop) provided
with the NEOREST
®
. This will assure the proper flow ratio is achieved
and allow for optimum performance of the unit.
*See warranty for details.
There are two types of precautionary symbols. The symbols and definitions
appear below.
When this symbol appears, precaution should be
taken to ensure proper and safe use of the
product. Ignoring this precaution could result in
injury or damage to personal property.
This symbol indicates a
prohibited use of the

Parts and Installation instructions
Installation Procedures
1 Installing the water shutoff valve
① Before installing the water shutoff valve, be
sure to remove any dirt or sand that may
have become lodged inside the valve.
② Wrap the sealing tape around the fitting on
the water supply pipe of the water shutoff
valve.
③ Please make sure that the water supply
from the water shutoff valve faces
downward at a 60° angle and toward the
side of the toilet.
2
Positioning the installation holes with the template
① Align the template with the centerline of the drain pipe on the floor.
② Mark the installation position for the mounting block and the outlet
connection.
Installing in the wrong direction
could lead to twisting of the
hose, causing flushing
problems or leaks.

3 Fixing the outlet connection and the mounting blocks
① The hex bolt should be placed in the hexagon shaped hole. The mounting plate should be placed over the bolt and screwed into the floor with self
tapping screws.
② To attach the front part, mount to the floor flange withTbolts, washers and nuts (Not included).
③ The front mounting block is then attached with self-tapping screws.
4 Toilet Installation
① Remove debris from around the periphery of the rubber joint on the outlet connection and the drain horn underneath the toilet before inserting the
drain horn into the outlet connection.
② Affix the installation holes (two holes) at the back of the toilet to the outlet connection with the washers and nuts and put the decorative caps on.
③ Insert the pan head screw into the installation hole at the front of the toilet and secure the toilet to the mounting block. Press the screw cap into the
screw head.
Please place the head of the hex bolt securely in the
hexagonal hole in the outlet connection.
If it isn't placed securely in the hole, the toilet could wobble.
Always
Do
Please be sure to secure the
rear of the toilet first. If the
front end is secured first, the
toilet could slide rearward,
resulting in leaks.

For Better Results
The manufacturer recommends that silicone caulking be applied around the bottom of the toilet bowl base to prevent
water and urine from seeping under the flooring material, resulting in a stained floor.

Installing the Washlet units
Refer to the installation instructions included in the packaging for the Washlet unit.
When checking the water flow the first time, if you
are making the check with the "manual flush handle",
be sure to turn it toward the front (toward the rim).
If you turn it "towards the rear," there is a
chance that air in the pipes will cause the water to
continue flowing.
