6 Kitchen Fan Control Center
Power for Starters and Fans
The KFCC is equipped with contactors that may have
thermal overloads attached to them. Each fan should
have a designated power source. The breaker size
(amps), wire gauge, phase, and voltage for each fan is
specified on the KFCC wiring diagram. Two speed fans
will require two separate starters.

NOTE
Light circuit must not exceed 1400W maximum.
Hood lights may be directly wired to light switch,
creating unoccupied terminals B2, B3 and B4. Please
refer to the wiring diagram specifically created for the
panel on the inside door of the control center.
Electrical Connections
NOTE
All field wiring of electrical equipment must be done to
meet all NEC and electrical codes.
The extent of field wiring required will depend on the
options and general configuration of the KFCC. Each
option is broken out in the next portion of this manual.
Each option will either be factory wired or will require
field wiring. Use 14 AWG, 60°C copper wire unless
otherwise specified.
Power for KFCC
The KFCC needs a power source to operate all inner
components. This power source cannot be on a shunt
trip breaker; the power must remain constant to the
panel, even in the event of a kitchen fire.
Power for KFCC
• 120 VAC, 15 amp circuit to terminals H1 and N1
CONTROL INPUT:
120 VAC, 15 AMPS FROM BREAKER

Power for Hood Lights (Optional)
If the KFCC is configured for hood light control, a
separate power source for each light circuit will need
to be run to the panel as well to power the lights. The
KFCC can provide up to three light circuits.
Power for Hood Lights
• 120 VAC, 15 amp circuit to terminals H2 and N2
(first light circuit)
• 120 VAC, 15 amp circuit to terminals H3 and N3
(second light circuit)
• 120 VAC, 15 amp circuit to terminals H4 and N4
(third light circuit)
Hood Lights
• To terminals B2 and W2 (first light circuit)
• To terminals B3 and W3 (second light circuit)
• To terminals B4 and W4 (third light circuit)
LIGHT INPUT: 120 VAC,
15 AMPS FROM BREAKER
