4. Electric wiring.
WARNING
Proper size of Flexible Cord and electric wiring must be installed to
avoid smoke emission and fi re hazards.
WARNING
The Home Shower must be permanently connected to the electric
supply through the ON/OFF DP (double pole) Switch having a contact
separation of at least 3 mm in all poles incorporated in the fi xed wiring.
This switch must be clearly identifi able but out of reach of a person
using a fi xed bath or shower.

Unscrew the Cord Holder and fi x the Flexible Cord.
Strip the lead wire (coating). Fasten the live wire (L)
and neutral wire (N) to the ELB (L,N) and earth wire
to the Ground Point with 1 N•m (10 kgf.cm) torque.
Fix back the Cord Holder to its position to clamp the
Flexible Cord.
Connect wires in correct polarity (L,N).

• Connect the wires in wrong polarity (L,N) causes an abnormal condition which may lead
to electric leaking, burning, etc.
• 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 defl ects greatly, the polarity of the Power Supply terminal is ‘L’.
Earth Rod.
WARNING
The Unit must be earthed.
Improper grounding could cause an electric shock.
• The Unit must be earthed.
• Earth Rod fi xing procedure. Select adapter 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 . If it is not, drive the Earth Rod deeper into ground surface or use 2
or 3 Rods.
