Section 2 Installation
Electrical Service
DANGER
Check all wiring connections, including factory
terminals, before operation. Connections can become
loose during shipment and installation.
DANGER
Units with two power cords must be plugged into
individual branch circuits. During movement, cleaning
or repair it is necessary to unplug both power cords.
n
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.
• Plug units with R290 refrigerant into a receptacle that is
a minimum of 14” (36cm) above the floor.
• 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.
