F. Electrical Connection / Installation
Note: All wiring must be completed prior to finishing
the unit.
All electrical connections shall be performed by a
qualified electrician.
WARNING! Risk of Fire, Electrical Shock and Injury!
Electrical wiring must comply with local building electri-
cal codes and the latest edition of the NFPA 70 National
Electric Code (NEC) other applicable regulations.
WARNING! Risk of Shock!
Label all wires prior to dis-
connection when servicing the appliance. Wiring errors
can cause improper and dangerous operation. Verify
proper operation after servicing.
This appliance is designed to be hard-wired for 120VAC
or 240VAC. A supplied plug-in kit is also available for use
with a 120VAC grounded receptacle. The AC voltage sup-
ply wiring should be properly grounded. A dedicated cir-
cuit is recommended. Other appliances on the circuit may
cause the breaker to trip or fuse to blow when the appli-
ance is operating.
Hard-Wired Installation
:
A 15 AMP circuit with a properly grounded outlet is
required for both 120VAC and 240VAC installations. Use
minimum size 14AWG Romex cable for the AC sup-
ply connection to 120 -240VAC, 60Hz, 15 AMP branch
circuit. Use copper wire only.
Note
: The appliance must be electrically connected and
grounded in accordance with local building elec-
trical codes.
1. Remove terminal block cover plate located on the
right end of the appliance.
2. Install a wire strain relief bushing into the cover
plate.
3. Terminate type NM-B wire to the terminal block,
ensure connections are secure, and tighten the
strain relief. Use 3/32 slotted heat screwdriver, or
equivalent, to depress the spring loaded terminals
for the conductors.
For 120VAC Applications:
The following instructions must be followed to install
a 3-wire NM-B Romex cable to the terminal block
shown on Figure 4.4.
a. Connect the ground wire (green) to the ground
terminal.
b. Connect the line input neutral wire (white) to the
N terminal.
c. Connect the line input voltage wire (black) to the
L1 terminal.
d. Tighten each terminal screw firmly and make
sure that they are tight.
e. Make sure that no wire is connected to the L2
terminal.
Power Cord Installation
The appliance power cord has a 3-pin NEMA-5-15P
plug. The power cord should not be used unless a
grounded receptacle is available.
1. Remove the terminal block cover plate located on
the right end of the appliance.
2. Disconnect the terminal block from the four wires
inside the appliance. Wires are released by discon-
necting the conductor wire connector. Discard the
terminal block cover plate.
3. Connect the conductor wire connector to the
connector on the block supplied with the power cord
kit. See Figure 4.5.
4. Inspect that the correct voltage is selected on the
selector switch located behind the glass on the
ceiling of the unit. Failure to do so could damage the
product. See Figure 4.6.
5. Replace cord kit terminal block cover plate
and retaining screws.
For 240VAC Applications:
The following instructions must be followed to install
a 4-wire NM-B Romex cable to the terminal block
shown on Figure 4.4.
a. Connect the ground wire (green) to the ground
terminal.
b. Connect the line input neutral wire (white) to the
N terminal.
c. Connect the line input voltage wire (black) to the
L1 terminal.
d. Connect the line input voltage wire (red) to the
L2 terminal.
e. Tighten each terminal screw firmly and make
sure that they are tight.
4. Ensure all connections are tight and there are no
exposed wires. Tighten Romex strain relief and reat-
tach junction box cover plate.
5. Inspect that the correct voltage is selected on the
selector switch located behind the glass on the ceil-
ing of the unit. Failure to do so could damage the
product. See Figure 4.6.
6. Replace terminal block cover plate and retaining
screws.
