• Do not use food pans deeper than 6” (15.2 cm).
• Do not place any hot items on the top surface.

Function And Purpose

This unit is intended and designed to keep food at proper serving temperatures. This unit is made for use in an ambient temperature below 86 °F (30 °C). Using in warmer temperatures will take unit out of NSF compliance. Modifying refrigeration parameters may void the warranty.

Hot food stations are not intended or designed to cook raw food or to reheat prepared food. Cold food stations are not intended or designed to cool or chill food. Food must be prepared and placed in food stations at proper serving temperatures. Refrigerated cold stations are best used for holding periods up to four hours. For best performance, stainless steel containers are recommended.

This equipment is not intended for household, industrial or laboratory use.

Unpacking the Equipment

1. Remove all packing material and tape, as well as any protective plastic from the equipment.
2. Clean any glue residue left over from the plastic or tape.
3. Dispose all packaging materials in an environmentally responsible manner.

Installation

This unit must be installed on a dedicated electrical circuit in accordance with local codes. Installation must be qualified service personnel.

Clearance Requirements

• One, two and three well drop-ins are zero clearance on all sides.
• Four well drop-in requires zero clearance on sides and 1 1/2” clearance at the bottom.

Venting Requirements

The Hot/Cold Drop-ins must have adequate ventilation. Minimum requirements are listed in the table below.

Drop-in

| Number of cutouts|

Size

---|---|---
Intake| Discharge
One Well| 1| 1| 8″ x 10″
Two Well| 1| 1| 8″ x 10″
Three- Well| 1| 1| 8″ x 10″
Four-Well| 2| 2| 8″ x 10″

The preferred location for the venting cutouts is on the short ends of the cabinet. If the short end are not available the long sides can be used. See drawings below. When louvers are installed in the long sides, Vollrath recommends using a fan to assist air movement.

Control Box Mounting

Controls must be mounted on the operator side (raceway side) for proper orientation with wells. The control box requires 3″ of depth in the cabinet when using the included frame. Without the frame, the control box requires 4″ of depth in the cabinet.
