Modular Drop-In: Four Well Hot
DESCRIPTION
The modular drop-in is designed for top-mount installation and
does not require hard-wiring. The drop-in comes complete
with a 6-ft. (182.8 cm) power cord with plug and a 4-ft.
(121.9 cm) control cord for remote installation.
Full-perimeter drip-edge contains spills and condensation
within the stainless steel countertop area of the drop-in.
Drip-edge adds additional strength to the flange area.
Drop-in can operate wet or dry, however, moist operation is
recommended for even heating of the food product. It meets
NSF4 performance standards when using moist heat.
High-density glass-fiber insulation allows zero-clearance
installation and use of 625W elements for lower energy
consumption and reduced costs. Also available with 1000W
elements.
Stainless steel wells are 6³⁄₈" (16.2 cm) deep to allow use of
full-size and fractional pans up to 6" (15.2 cm) deep while still
providing moist heat. Adaptor bars are recommended when
using fractional pans.
WARRANTY: All models shown come with Vollrath’s standard
warranty against defects in materials and workmanship. For full

AUTO-FILL OPTION
Field-installed option that efficiently maintains a constant water level. Eliminates the need to monitor wells and add water, reducing
operating and labor costs. Attaches easily to manifold drain assembly using simple tools. The check valve/siphon prevents cross
contamination of drain and potable water lines. NOTE: The auto-fill reservoir is approximately 6 x 17 (15.2 x 43.2) and requires
additional space in the cabinet.
DIMENSIONS
❑ Cutout Dimensions: 27½" x 25¼" (69.9 cm x 64.1 cm). Opening cutout must have a 7/8" (2.2 cm) corner radius.
