Receptacle
 The Auto-Line circuitry in this
unit automatically links the
power source to the primary
voltage being applied, either
115 or 230 VAC.
An individual branch circuit capa-
ble of carrying 30 amperes and
protected by fuses or circuit
breaker is recommended. Rec-
ommended fuse or circuit break-
er size is 30 amperes.
 Unit is supplied with a 115
VAC plug (CE models are
not supplied with a line
cord plug). For 230 VAC
operation, have a qualified
person obtain a proper
plug that meets all applica-
ble codes, and install the
plug according to the
