① Lead the Flexible Cord connected to ELB terminal
inside the Unit: 2.5 mm², 3 core Flexible Cord.
② Unscrew the Cord Holder and fix 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.
③ 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 deflects greatly, the polarity of the Power Supply terminal is ‘L’.

4. Electric wiring
Proper size of Flexible Cord and electric wiring must be installed to avoid
smoke emission and fire hazards.
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 fixed wiring. This switch
must be clearly identifiable but out of reach of a person using a fixed bath
or shower.
