Preparation
Electrical Requirements The unit requires a 120V AC, 60Hz. 15A branch circuit. For future service, install
the outlet in an easily accessible location.
Mounting Requirements The unit must be mounted to the surrounding housing. See “General Information”
on page 3 for suggestions for determining hood height.
For best results, install the unit as far up in the housing or hood as possible. This
will improve the function of the appliance.
When calculating the load for the housing support system, be sure to include the
weight of the ventilation unit. See “Ventilation Unit Weight” on page 4. for unit
weight by model.
For proper performance, the housing must cover the entire cooking surface.
Build housing to correspond with Figure 7: Housing Cutout Dimensions - 20 7/8”
(53 cm) models or Figure 8: Housing Cutout Dimensions - 28 3/4” (73 cm) mod-
