HPB SERIES PROOF BOXES

SAVE THESE INSTRUCTIONS

GENERAL

The HPB Series Roll-In Proof Boxes are one-, two-, or four-rack cabinets for proofing dough. The Proof Box’s AirWash™ Humidification System provides ideal proofing conditions and includes accurate controls for temperature, humidity, and time.

Interior and exterior construction is 300 series stainless steel throughout. Interior bumper guards are provided for the left, right, and rear walls.

Glass door is an option on the single rack model only. Door hinging on the single door unit can be reversed, if necessary, by a service technician (but a new ramp is required). Two-door units are hinged on the side walls and open out from the middle. There is no center post. A door closer is provided above the right hand door.

Proofers may be ordered with either the Proof Box control or with the Thaw Proofer control:

• The Proof Box control is a single-stage control which controls temperature, humidity, and time.

• Thaw Proofer control is a two-stage control that can work just like the Proof Box control; or, it can also allow an initial Thaw stage to be automatically followed by a Proof stage. Each stage independently controls temperature, humidity, and time.

Immediately after unpacking, check for possible shipping damage. If the cabinet is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.

Prior to installation, test the electrical service to verify that it agrees with the data plate located in the upper left corner inside the cabinet.
