Electrical Safety

ENGLISH

Temporary Use of an Adapter

We strongly discourage the use of an adapter due to potential safety hazards. For temporary
connections, use only a UL-listed adapter, available from most local hardware stores. Ensure that the
large slot in the adapter is aligned with the large slot in the receptacle for a proper polarity connection.
To disconnect the power cord from the adapter, use one hand on each to avoid damaging the ground
terminal. Avoid frequently unplugging the power cord as this can lead to eventual ground terminal
damage.

WARNING:  Never use the appliance with a broken adapter.  

We strongly discourage the use of an extension cord due to potential safety hazards. For temporary
situations, use only CSA certified and UL listed 3-wire grounded extension cords, rated 15 A, 125 V.
