Mechanical Specifications
Quad Grille Outlet
Quad grilles are square multi-directional grilles that allow four different discharge directions by
rotating the grilles 90°. The quad grille construction is a black plastic material (NORYL-SE 1-731)
with a 15° angle on the discharge louvers. Quad grilles are recessed into the discharge panel to
prevent condensation from forming on the grille exterior. Quad grilles are available on all cabinet
style units.
Bar Grille Inlet/Outlet
Bar grilles are formed steel grille options available on the discharge of all cabinet units, the return
of vertical cabinet, vertical slope tops and low vertical cabinet units. The grilles have a black paint
finish with 18-gage steel construction. The louvers are formed at a 15° angle, and the discharge
grilles are recessed to prevent condensate formation on the surface of the grille. The bar grilles are
fixed in one discharge direction.
Sub-bases
Sub-bases elevate vertical cabinet or slope top cabinet units to a specified height; for example, to
reach the bottom of a window sill. The sub-base also provides a cavity through which to run piping
underneath the fan-coil unit. Sub-bases are 16-gage steel construction and have the same black
paint finish as the unit’s base. The sub-base is available in heights between 2”–7” in 1/2”
increments. The sub-base depth and width is identical to the unit’s dimensions.
