Installation
22 English
To connect the water hoses to the faucets:
1. Connect one end of each water hose to
the Hot or Cold tap.
2. Turn the fittings by hand until they are
tight, and then tighten them by just an
additional two-thirds of a turn with a
plier. Do not overtighten the fittings.
You can damage them.
3. When done, pull the water hoses up
and down to check if they are properly
connected.
4. Put the other ends of the hoses into
a bucket and open the taps for 10-15
seconds to remove impurities. When
done, close the taps.
