Availability

Before­installing­the­machine,­consider­the­avail-
ability­and­proximity­of­the­required­power­supply­
circuit.­ If­ an­ existing­ circuit­ does­ not­ meet­ the­
requirements­for­this­machine,­a­new­circuit­must­
be­installed.­To­minimize­the­risk­of­electrocution,­
fire,­ or­ equipment­ damage,­ installation­ work­ and­
electrical­wiring­must­be­done­by­an­electrician­or­ ­
qualified­service­personnel­in­accordance­with­all­
applicable­codes­and­standards.
Electrocution, fire, shock,
or
may occur if machine is
not properly grounded
and connected to power
supply.

Full-Load Current Rating

The­ full-load­ current­ rating­ is­ the­ amperage­ a­
machine­draws­at­100%­of­the­rated­output­power.­
On­ machines­ with­ multiple­ motors,­ this­ is­ the­
amperage­drawn­by­the­largest­motor­or­sum­of­all­
motors­ and­ electrical­ devices­ that­ might­ operate­
at­one­time­during­normal­operations.
Full-Load Current Rating at 220V .. 14.2 Amps
The­full-load­current­is­not­the­maximum­amount­
of­amps­that­the­machine­will­draw.­If­the­machine­
is­overloaded,­it­will­draw­additional­amps­beyond­
the­full-load­rating.
If­the­machine­is­overloaded­for­a­sufficient­length­
of­time,­damage,­overheating,­or­fire­may­result—
especially­ if­ connected­ to­ an­ undersized­ circuit.­
To­ reduce­ the­ risk­ of­ these­ hazards,­ avoid­ over-
loading­ the­ machine­ during­ operation­ and­ make­
sure­it­is­connected­to­a­power­supply­circuit­that­
meets­the­specified­circuit­requirements.

Circuit Information

A­ power­ supply­ circuit­ includes­ all­ electrical­
equipment­between­the­breaker­box­or­fuse­panel­
in­the­building­and­the­machine.­The­power­sup-
ply­circuit­used­for­this­machine­must­be­sized­to­
safely­handle­the­full-load­current­drawn­from­the­
machine­ for­ an­ extended­ period­ of­ time.­ (If­ this­
machine­ is­ connected­ to­ a­ circuit­ protected­ by­
fuses,­use­a­time­delay­fuse­marked­D.)
For your own safety and protection of
property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.
Note: Circuit requirements in this manual apply to
a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, con-
sult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
