FIRMLY FIX THE WATER SUPPLY PIPE
An impact applied to the hose due to high water pressure
may cause vibrations.
Fix the water supply pipe firmly so that it does not loosen.
There is a danger vibration or flooding.

HOW TO CHECK WATER PRESSURE
• When installing a flush toilet, check that the required water pressures (hydrostatic pressure and flow pressure) specified for
each appliance are secured.
• If the water pressure exceeds 0.75MPa, use a pressure reducing valve before installation for use.
[Water Pressure Checks]
Hydrostatic pressure and flow pressure checks are required for installing water supply appliances. If no water shutoff valves or
pressure measuring devices are prepared beforehand, connect the appliances as shown below to measure the hydrostatic pressure
and flow pressure. By using a pressure measuring device, it will be easy to check the installation availability of the appliance.
The flow pressure greatly varies, depending on the peripheral conditions including piping. Be sure to make water pressure
measurement with the water supply pipe where the appliance is installed.
[Hydrostatic Pressure Measuring Method]
Make water pressure (hydrostatic pressure) measurement in a state where valve 1 is fully opened and valve 2 is fully closed.
[Flow Pressure Measuring Method]
(1) First, check that valve 2 is fully closed and valve 1 is fully opened. Next, gradually open valve 2. Then the hydrostatic
pressure will gradually decrease (the flow pressure is the water pressure at the time of water supply).
(2) Adjust valve 2 so that the water pressure will set to the minimum required water pressure of the product. Then close valve 1.
(3) Empty the bucket. Then fully open valve 1 and measure the time until the water level reaches the scale of the bucket.
Calculate the flow rate from the bucket capacity divided by the period of time and check that the flow rate necessary for the
use of the product is secured.
• If the installed appliance is used simultaneously with the water supply appliance in the kitchen, washroom, etc., the flow pressure
and the flow rate will decrease. In that case, measure the flow pressure in a simultaneous operating state of the appliances.
