18 INSTALLATION
WARNING
• This appliance must be connected to a grounded
metal, permanent wiring system, or an
equipment-grounding conductor must be run
with the circuit conductors and connected to the
equipment-grounding terminal or lead on the
appliance.
• The appliance has its own terminal block that
must be connected to a separate 240 VAC, 60-
Hertz, single-phase circuit, fused at 15 amperes.
(The circuit must be fused on both sides of the
line.) ELECTRICAL SERVICE FOR THE APPLIANCE
SHOULD BE OF THE MAXIMUM RATE VOLTAGE
LISTED ON THE NAMEPLATE. DO NOT CONNECT
THE APPLIANCE TO 110-, 115-, OR 120-VOLT
CIRCUIT.
• If the branch circuit to appliance is 15 ft. (4.5 m)
or less in length, use UL (Underwriters
Laboratories) listed No.-10 AWG wire (copper
wire only), or as required by local codes. If over
15 ft. (4.5 m), use UL-listed No.-8 AWG wire
(copper wire only), or as required by local codes.
Allow sufficient slack in wiring so the appliance
can be moved from its normal location when
necessary.
• The power cord (pigtail) connection between the
wall receptacle and the appliance terminal block
IS NOT supplied with the appliance. Type of
pigtail and gauge of wire must conform to local
codes and with instructions on the following
pages.
• Do not modify the plug and internal wire
provided with the appliance.
• The appliance should be connected to a 4-hole
outlet.
• If the plug does not fit the outlet, a proper outlet
will need to be installed by a qualified electrician.
• Connect the power cord to the terminal block.
Each colored wire should be connected to the
same color screw. Wire color indicated in manual
is connected to the same color screw in the
block.
• Grounding through the neutral conductor is
prohibited for: (1) new branch-circuit
installations and (2) areas where local codes
prohibit grounding through the neutral
conductor.
• This appliance is supplied with the neutral wire
grounded. This white ground wire MUST BE
MOVED to the neutral terminal when a 4-wire
cord is to be used, or where grounding through
the neutral conductor is prohibited.
Four-Wire Power Cord
1 Remove the terminal block access cover on
the upper back of the appliance.
2 Install UL-listed strain relief into the power
cord through-hole.
3 Thread a 30-amp, 240-volt, 4-wire, UL-listed
power cord with #10 AWG-minimum copper
conductor through the strain relief.

c UL-Listed 4-Wire Power Cord
4 Transfer the appliance's ground wire from
behind the green ground screw to the center
screw of the terminal block.
5 Attach the two hot leads (black and red) of the
power cord to the outer terminal block
screws.
6 Attach the neutral (white) wire to the center
screw of the terminal block.
7 Attach the power cord ground wire to the
green ground screw.
• A UL-listed strain relief is
required.
• Use a 30-amp, 240-volt, 4-wire, UL-listed
power cord with #10 AWG-minimum copper
conductor and closed loop or forked terminals
with upturned ends.
