About dripping
Because the faucet uses “the method of installing switch in the water inlet” (as shown below),
the following conditions will happen, but they are not abnormal phenomena.
After pressing the water stop/water run through button, the outlet
water will not stop immediately, and the main spout and drain outlet will
have dripping water.
( In case of low water temperature (in winter or when the underground water is used)
or if the air enters into the inside of the cartridge, this phenomenon will be relatively
easy to happen.
During and after the automatic cleaning, the water residing in the faucet will flow
out due to the bubbles generated by electrolysis.
This phenomenon is also easy to happen when the water pressure is relatively high.
At this time, please contact a dealer or subordinate service station of Panasonic.)
Compared with the early use period, the amount of drip has increased.
( It is due to the clogging of the cartridge with the increase of the using time.
If it is a concern, the cartridge can be replaced. The dripping phenomenon will recover
to that in the early use period when the water outflow stops.)
The so-called method of installing
switch in the water inlet
In this method, the main unit
(cartridge) bears water pressure only
when water flows out.
Therefore, this method can avoid major
damage caused by water leakage while the
user is not at home.

Please do not use piping that adopts the method of installing switch at the main spout.
In the so-called method of installing switch at the main spout, the main unit (cartridge) is
subject to water pressure all the time.
The water will stop immediately after pressing
