CAUTION
Connect the power cord and check L1/L2/N voltage. If the voltage is low, it may not heat
properly.
WARNING
• All U.S. models are designed for a 3-wire system connection. The dryer frame is
grounded to the neutral conductor at the terminal block. A 4-wire system connection
is required for new or remodeled construction, mobile homes, or if local codes do not
permit grounding through neutral. If you use the 4-wire system, you cannot ground the
dryer frame to the neutral conductor at the terminal block.
• Remove the terminal block cover plate. Insert the power cord with a UL-listed strain
relief through the hole provided in the cabinet near the terminal block.
