ELECTRIC WIRE CONNECTIONS
1. Be sure to cut off the main power supply switch every time before starting any electrical work
Use dual insulated wire with at least 4 square meters cross-section (WH-236E, WH-239EP).
Use dual insulated wire with at least 6 square meters cross-section (WH-246E).
Connect electric wire to the unit from the main switch board through the main breaker which is
located outside the bathroom. Wire connection must be permanent.

2. Electric wire connection to the unit can be done by 2 methods. (as illustrated) Drill a small hole at the
rubber to insert the wire on side or at the rear of the unit.
Peel the wire and connect to the ELB checker by connecting the high voltage cable to the terminal “L”
and connect neutrons wire into the terminal “N”. Use screwdriver to tighten the wires. (Force gauge
approximately 12 kgf.cm). If the wires are connected into the wrong terminal, the unit will not work
properly. It may result in damage to the circuit or may cause danger to the user.
Connect the wire at rear of the unit.
