If the Adjust Holder needs to be cut due to different
wall height make sure the Adjust Holder is touching
to the wall or tiles to prevent possibility of water
leakage at the Filter Body Assembly.
• The Unit must be earthed.
• Select suitable place to bury the optional Earth Rod (DQ-6H) for at least 70 cm below ground surface.
• Ensure that the ground resistance is less than 100 Ω. If it is not, drive the Earth Rod deeper into ground surface or use 2 or 3 Earth

③ Connect wires in correct polarity (L,N).
• Connecting the wires in wrong polarity (L,N) causes an abnormal condition which may lead to
electric leaking, burning and such.
• Before wiring, please check polarity (L,N) with voltage range of a tester or voltmeter by connecting
one terminal of the meter to earth while the other to one of the Power-Supply Terminals.
• When the needle of the meter deflects greatly, the polarity of the Power-Supply Terminals is ‘L’.
