Installation, Operation, and Care ofAHP SERIES PROOFERS

SAVE THESE INSTRUCTIONS

GENERAL

The AHP Series Roll-In Proof Boxes proof racks of dough products under controlled temperature andhumidity prior to baking. The proof boxes have three basic equipment options: Proofers (AHP models)are equipped to proof dough only; Thaw-Proofers (AHTP models) are equipped to proof and/or tore-awaken frozen dough; and Proofer-Retarders (AHPR models) are equipped to proof the dough andthen chill it or slowly thaw and then proof the dough prior to delayed baking. A programmable 7 daytime switch controls proof and retard cycles on AHPR models; two individual timers, operatingsequentially, control thaw and then proof cycles on AHTP models. All AHP Series Proofers have easy-to-clean stainless steel interior and exterior panels with sandwiched urethane foam insulation.

Different size proof boxes accommodate rack(s) as follows:

INSTALLATIONASSEMBLY

Models AHP1S, AHPR1S, and AHTP1S are shipped completely assembled from the factory. OtherAHP Series Proofers are shipped knocked-down for installation on the job site. Ceiling and wall panelsare locked together with cam-locks; the floor is fastened to the wall panels with stainless steel screws.

Correctly install proofers following these step-by-step instructions:

1. If there are two or more back panels, place the back panels [B] in vertical, upright position. Insertthe hex wrench in the lock hole and turn clockwise until the locking arm strikes the pin in the adjacentpanel, locking panels together. If lock fails to engage, turn wrench counterclockwise and again turnwrench clockwise until panels are properly locked together.

2. Tilt the assembled back panel(s) and lay them on the floor with the exterior side down.

3. Select the left side wall panel [S1]; place it in position with the back panel assembly; and, lock themtogether with the cam lock by turning the hex wrench clockwise. Make sure top and bottom edgesof side and back panels are flush.

4. Repeat step 3 with the right side wall panel [S2].

5. Fasten the floor to the bottom of the back and side panels with stainless steel screws.

6. Place the roof panel [C] in position with the walls. First lock the roof panel [C] and the left side wallpanel [S1] by turning the hex wrench clockwise; then, lock the roof panel [C] and the right side wallpanel [S2] by turning the hex wrench counterclockwise.

7. The proofer box can now be put in an upright position.

8. For AHP and AHTP models: Lock the roof panel [C] to the back wall assembly by turning the hexwrench clockwise.

9. For AHPR models:a. Unlock the roof and side panel cam locks and install the mullion module (see pages 19 21).

b. Lock the roof and side panel cam locks.c. Seal all joints between panels, ceiling, and floor with an NSF approved sealant, provided.d. Assemble brass couplers, sight glass, and filter to the refrigeration lines on the evaporator and

condensing unit.e. Install permagum around the refrigeration lines, add fiberglass insulation, and install sheet metal

covers on the ceiling (inside) and roof (outside) where refrigeration lines go through the ceiling.f. Set the condensing unit on the top of the cabinet with the condensing coil facing front and the

refrigeration lines aligned. Fasten the condensing unit in place.g. Connect the electric wires from the condensing unit to the controls: Pass wires through ceiling

to the opening for the controls and attach them to the terminal block. (220Volt: Wire 12 to TB12,Wire 16 to TB16, and Gnd to Gnd. 120Volt: Wire N to TBN, Wire 16 to TB16 and Gnd to Gnd).

h. After completing steps 11 - 21, charge the refrigeration system with appropriate R22 or R134refrigerant and install the condensing unit cover to the front at the top of the cabinet. For allmodels: Low pressure Cut-Out = 13 psig; High pressure Cut-In = 22 psig.

10. For AHP and AHTP models: Seal all joints between panels, ceiling, and floor with an NSF approvedsilicone sealant, provided. Slide the humidifying unit into place and fasten it to the ceiling and thefloor; the top and bottom cover plates of the control panels should be removed to allow access tothe mounting slots. It is recommended that the side cover of the humidifying unit be removed duringinstallation.

PROGRAMMING A PAUSE OR TIME DELAY BETWEEN TWO PROGRAMS

To program a pause between the stop time of one program and the start time of the next, set the stoptime prior to the next start time as shown in the following examples:

EXAMPLE MODE START DAY START TIME STOP DAY STOP TIME

1 P1: Proofer Monday 8:00 AM Monday 5:00 PM

2 P2: Retarder Monday 5:30 PM Tuesday 7:30 AM

3 P1: Proofer Tuesday 8:00 AM Tuesday 5:00 PM

Between the stop time for example 1 and the start time for example 2, a 30 minute delay has beenscheduled. Also, a 30 minute delay is scheduled between the stop time for example 2 and the starttime for example 3. During this time delay, the fans will continue to run for a maximum of 30 minutes.

PLANNING YOUR WEEKLY SCHEDULE

If several days of the week have the same schedule, they can all be in the same program. Whenselecting the start days of the week, merely repeat the selection (use the Day Shift key followed by the

Day Set / Reset key repeatedly). Then select the start hour and minutes only once since they are tobe the same. Do the same for the stop days of the week and the stop hours and minutes. For example,if the P1 Proofer function were to be the same as example 1 above for Monday, Tuesday, Wednesday,Thursday, and Friday the final set displays would look like Figs. 32, 33.

If scheduling example 2 for five overnight retarder mode functions, the final set displays would look likeFigs. 34, 35. Notice the removal of Monday and inclusion of Saturday in the stop day selection.

CLEANING

Clean the inside of the cabinet and the doors weekly with a warm water solution of mild household liquiddishwashing detergent (such as Palmolive green or Ivory). Do not use anything containing grit,abrasive materials, bleach, or harsh chemicals. Be cautious with new or improved formulas; use onlyproducts approved for stainless steel. Rinse thoroughly and dry with a clean soft cloth. Do not usesteel wool to clean surfaces.

Remove the filter and rinse clean weekly. Replace filter when necessary.

NOTE: Failure to follow use, care and maintenance instructions may void your Hobart warranty.

RETARDING

The retarder temperature is usually set at 38F. Defrosting frozen dough at retarder temperaturestakes 6 hours minimum; dough products can be stored for as long as 48 hours in the retarder using thecool humid air so dough products do not dry out. Dough should not be refrozen after thawing. Theretarder slows the yeast fermentation process, reduces gas formation, and inhibits raising of dough.

Products removed from the retarder should be left at room temperature for 5 7 minutes before beingput in the proofer. This will reduce moisture condensation when cold metal pans are placed in the warmhumid proofer.

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. The chart below is for guidelines only ask your dough supplier for technicalproduct reports to set up your own chart.
