before operation. Connections can become loose during
shipment and installation.

Warning
This appliance must be grounded and all field wiring must
conform to all applicable local and national codes. Refer
to rating plate for proper voltage. It is the responsibility of
the end user to provide the disconnect means to satisfy
the authority having jurisdiction.
• Salad and Mega top 4460, 4464, and 4472 models are
equipped with a power disconnect switch located at
the rear of the unit just below the thermostat control
knob. Switch must be in the “on” position for the unit to
operate.
• All electrical work, including wire routing and grounding,
must conform to local, state and national electrical codes.
• The equipment must be grounded.
• A separate fuse/circuit breaker must be provided for each
unit.
• The maximum allowable voltage variation is ±10% of the
rated voltage at equipment start-up (when the electrical
load is highest).
• Check all green ground screws, cables and wire
connections to verify they are tight before start-up.
GROUND FAULT CIRCUIT INTERRUPTER
Ground Fault Circuit Interrupter (GFCI/GFI) protection is a
system that shuts down the electric circuit (opens it) when it
senses an unexpected loss of power, presumably to ground.
Welbilt does not recommend the use of GFCI/GFI circuit
protection to energize our equipment. If code requires the
use of a GFCI/GFI then you must follow the local code. The
circuit must be dedicated, sized properly and there must
be a panel GFCI/GFI breaker. We do not recommend the
use of GFCI/GFI outlets to energize our equipment as they
are known for more intermittent nuisance trips than panel
breakers.
RATED AMPERAGES, HORSEPOWER, VOLTAGE & POWER
CORD CHART
Maximum 6ft (1.8m) cord with three-pronged plug. Plug
into a three-pronged wall outlet for proper grounding of the
