CAUTION
All the electrical connections must be carried out by qualified installers and all the wirings must be
connected according to the wiring diagram.
Make ground connection prior to any other electrical connections.
All power sources must be turned off before wiring work and do not turn on the power until you have
made sure all the wirings have been safety checked.
A main switch and circuit breaker or fuse must be installed, the capacity should be above 1.5 times of
maximum current in circuit.
An individual branch circuit and single socket used only for this appliance must be available.
Wire cross section is depending on the rated current and national, state and local electrical wiring
code. Consult local building codes and National electrical code for special requirement.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard.
The unit must be connected to the main power supply by means of a circuit breaker or a switch with a
contact separation of at least 3mm in all poles. Installation of a residual current device (RCD) having
a rated residual operating current not exceeding 30mA is advisable.
