ELECTRICAL SUPPLY
Fora1-phase208V~circuitwithneutral,
the unit must be connected according to the

LOCATION
The rotisserie must be installed on a level surface. The installation location must allow adequate
clearances for servicing and proper operation.
ATTENTION: All external connections to the rotisserie must be made according to
local, state and national regulations by skilled installers.

tricalpowersupplyusingexibleconduit,adequatemeansbeprovidedtolimitmovementof
the appliance without depending on or transmitting stress to the electrical conduit. This means
that, as part of the installation, the base or bottom unit of stacked models must be secured to
the building structure (typically either wall or floor) to limit the movement of the appliance
and, thus, helping to prevent damage to the conduit during cleaning, maintenance and service
operations.
