Installation, Operation, and Care of
AHP SERIES PROOFERS
SAVE THESE INSTRUCTIONS
GENERAL
The AHP Series Roll-In Proof Boxes proof racks of dough products under controlled temperature and humidity 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 to re-awaken frozen dough; and Proofer-Retarders (AHPR models) are equipped to proof the dough and then chill it or slowly thaw and then proof the dough prior to delayed baking. A programmable 7 day time switch controls proof and retard cycles on AHPR models; two individual timers, operating sequentially, 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:

INSTALLATION
ASSEMBLY
Models AHP1S, AHPR1S, and AHTP1S are shipped completely assembled from the factory. Other AHP Series Proofers are shipped knocked-down for installation on the job site. Ceiling and wall panels are 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. Insert the hex wrench in the lock hole and turn clockwise until the locking arm strikes the pin in the adjacent panel, locking panels together. If lock fails to engage, turn wrench counterclockwise and again turn wrench 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 them together with the cam lock by turning the hex wrench clockwise. Make sure top and bottom edges of 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 wall panel [S1] by turning the hex wrench clockwise; then, lock the roof panel [C] and the right side wall panel [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 hex wrench 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 R134 refrigerant and install the condensing unit cover to the front at the top of the cabinet. For all models: 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 approved silicone sealant, provided. Slide the humidifying unit into place and fasten it to the ceiling and the floor; the top and bottom cover plates of the control panels should be removed to allow access to the mounting slots. It is recommended that the side cover of the humidifying unit be removed during installation. On completion, seal humidifying unit at ceiling and floor using an NSF approved silicone sealant, provided.
–4 –
Steps 11 - 22 apply to all models:
11.Mount the bumper(s) at the upper part of the humidifying unit; fasten at front and back of control panel by screwing bracket(s) to the wall with two stainless steel screws, each. Also mount the bumpers on the back and side panels. Seal bumpers to walls and doors with an NSF approved silicone sealant, provided.
12.Mount the hinge pin assembly to the front side wall(s). Place one nylon spacer behind each hinge pin assembly.
13.Mount the white plastic halves with spacers on the door(s) but do not tighten screws.
14.Hang the door on the hinge pin assemblies: Carefully align the door with the door frame; press against the door to make sure the seals are tight against the frame; and, tighten the white plastic halves of the hinges making sure they are straight. If there are two or more doors, mount them in the same way.
15.Mount the outside door handle/bumper and the inside bumper by screwing to the door and sealing with an NSF approved silicone sealant, provided.
16.Mount the bracket for the door closer on the top of the door. Mount the hydraulic door closer (see Fig. 47 on page 33.
17.Place the drain pan at the bottom of the humidifying unit. Fasten the plastic hose to the drain pan with a hose clamp. Remove insulation from the knockout on either the left or right side wall panels; pass the hose through the hole and continue to a floor drain. Refer to page 6.
18.Install the water supply line and solenoid assembly. A water filter (not supplied) is recommended to remove particulates ahead of the spray nozzles in the humidifier. The water pressure should be at least 43 psig (2 kg/cm2). Refer to page 6.
19.Install ramp(s).
20.Refer to page 6 for Electrical Connection information.
21.When the proofer has been set and leveled in its final installed position, seal all around the proofer perimeter where it contacts the building floor with an NSF approved silicone sealant, provided. Wipe off any excess sealant.
Refer to the drawings for your proofer:

PLUMBING CONNECTIONS
WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY, AND PLUMBING CODES.
WATER SUPPLY
Water must be proper hardness and pH. The recommended hardness is 4 – 6 grains per gallon. The recommended pH is 6.5 – 8.0. Consult your local water company and/or water conditioner dealer before installing the AHP Series Roll-In Proof Box to make sure the water supply meets these conditions.
Connect potable water supply to the 1/4" NPT supply connection; the flow rate is 2 gallons per hour.
DRAIN CONNECTION
The drain hose connects to the 1" O.D. fitting at the bottom of the drain pan on the humidifying unit. Overflow drain knockouts are provided on both ends of the cabinet to allow drain installation on either end. Run the hose to a floor drain.
ELECTRICAL CONNECTION
WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL ELECTRICAL CODES.
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE DISCONNECT SWITCH INDICATING THAT YOU ARE WORKING ON THE CIRCUIT.
