■ 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 (as detected by a sensor within the unit). It should be noted that the standard
range of working pressures allowed by model codes is 20 to 80 psi static.*
It is necessary to install the water supply valve (angle stop) provided with the NEOREST.
This will assure the proper flow rate is achieved and allow for optimum performance of the unit.
*See warranty for details.
The following water volume will ensure
sufficient water pressure.
If a pressure gauge is unavailable, the fill method
may be used as follows.
Water volume (for 10 sec)
1.5 Gallons (5.5 L) or more
How to check the water pressure:
(Measuring Procedure)
Allow the water to
flow into the bucket
for 10 seconds and
measure the water volume.
Prepare two buckets to
hold the water.
