4.Be sure to connect the feed water hose to the faucet equipped with the sink.
Connection of the hose to the faucet
without sink equipment may cause
damage in the case of disconnection
or damage of the hose. Always
connect to the faucet equipped with
the sink.
5. When the sink is distanced from the faucet, use an optional “inlet unit” (see P.
24).
The “inlet unit” is of a construction in which the connection to the faucet is harder to loosen
than the standard feed water hose set even under fluctuating water supply pressure.
When the faucet is not available, select the appropriate coupling joint from
optional “connector coupler joints” (see P. 24).
