※
Initially, the one-touch joint may be hard to insert and application of excessive force for
insertion may cause the insertion port to break. When this is hard to insert, carry out
connection in a state as removed from the resin installation plate while taking care not to insert
in the bent state.
※
Once the one-touch joint is inserted, pull on the hose to confirm connection and to make sure
that the coupler is not disconnected.
※
Direct the one-touch joint connected to the front ion exchange resin cartridge upward
or right (right side looked from front). If it faces downward, the joint will touch the back
plate of the door preventing the door from opening.
※
When removing the ion exchange resin cartridge, relieve the pressure before disconnecting
the coupler while referring to “Before replacement of the ion exchange resin cartridge and
pre
treatment cartridge ” of P.28. The coupler can be removed with ease by pulling on it while
pressing a black portion to the depth. For removal, reverse the order of installation and follow
the sequence of “
Front・IN→Front・OUT→Back・IN→Back・OUT .” Note also that water may drip
from the ion exchange resin cartridge when the one-touch joint is disconnected.
※
Reverse installation of ion exchange resin cartridges or wrong connection of IN and OUT of
each cartridge may cause failure, resulting in shorter service life of the cartridges.
