Electrical connection
Although the appliance has two dryers which operate independently, there is only one electric connection.
Make sure that the characteristics of the available power supply correspond to those of your dryer,
indicated on its identification plate, and that the cable section and other line accessories can supply the
necessary power.
The machine leaves the factory with the complete electrical installation, therefore, it will be sufficient to
remove the cover located at the rear of the tumble dryer and connect each terminal to phase L1, neutral
N and the ground connection at the terminals connection or main switch.
A circuit breaker and differential switch
MUST
be inserted between the wiring and the mains, and the
sensitivity of the differential switch must be 300 mA. Higher sensitivity, for example 30 mA, common in
domestic installations may cause operating anomalies in the machine.
Connect the phase and the neutral in the main switch and the earth protection in the earth connection next
to the main switch according to the following table (section in mm2).
Correct earthing is essential to guarantee the safety of users and correct operation.
The dryer, when installed, must be electrically grounded in accordance with local codes or, in the
absence of local codes, with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical
Code, CSA C22.1
