Installation, Operation, and Care ofHPB 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 ProofBoxs AirWash Humidification System provides ideal proofing conditions and includes accuratecontrols for temperature, humidity, and time.
Interior and exterior construction is 300 series stainless steel throughout. Interior bumper guards areprovided 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 bereversed, if necessary, by a service technician (but a new ramp is required). Two-door units are hingedon the side walls and open out from the middle. There is no center post. A door closer is provided abovethe 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 canalso allow an initial Thaw stage to be automatically followed by a Proof stage. Each stageindependently controls temperature, humidity, and time.

REMOTE CONTROL Proofer and Thaw Proofer (Fig. 8, When Equipped)
Fig. 8
The Remote Control is used in conjunction with either Proofer Controls or Thaw Proofer Controls
described on the previous two pages. The MODE key is used only on Thaw Proofer models.
PROOFING
Controlled temperature and humidity in the proofer promotes yeast fermentation which generates gasand causes the dough to rise. Proofing takes from 45 60 minutes depending on the product. Atemperature setting of 95F and humidity at 85% are typical but will vary slightly depending on theproduct being proofed. Ask your dough supplier for information so you can make a chart with theTemperature, Humidity, and Proof Times required for the products you will be baking.
