GENERAL DESCRIPTION
Theory of Operation
The BAP Proofer is a controlled atmosphere chamber. Temperature and humidity can be set
independently to meet your particular proofing needs. In Proof mode air temperature is increased as the air
duct heater is energized. Humidity is increased as water is sprayed in the air duct. Air is circulated
continuously to provide positive movement from bottom to top, creating a uniform distribution of warm,
humid air.

Instructions for Installer:
Note: Assemble the proofer per the BAP installation instructions provided.
Step 1:
Remove the evaporator(s) from the shipping container. Remove the cover with the fan installed and inspect the evaporator,
noting any dents or loose screws. Repair as needed. Inspect the evaporator tubing for holes leaks or unsoldered joints. (It is
easier to do this inspection before you mount the evaporators.)
Step 2:
Refer to the table page 49 for the correct location of the evaporator in the cabinet.
Note: A 12” minimum air gap to front
Evaporator Locations.
Hold the evaporator (less the cover) against the ceiling and mark the location of the 4 mounting holes. Drill these holes with
a ¼” drill through the ceiling. Mount the evaporator(s) with the ¼” x 3” stainless steel screws, washers, lock washers and
nuts provided. Locate the approximate location of the fan connection inside the evaporator(s). Drill a 3/8” hole through the
evaporator(s) and through the ceiling at this location. Install the 3/8” plastic busing in these holes to protect the electrical
wires.

Step 3:
Locate the flexible electrical conduit and connectors provided with the retarder kit. Install one connector in the available
conduit hole in the back of the header assembly.
Locate (do not attach at this time) the ventilated electrical connection box over the 3/8” diameter hole(s) in ceiling with the
bushing(s) installed. Install conduit connectors in these boxes.
Note: If there are two evaporators provided, a box will need to be installed over each electrical connection hole.
Stretch the electrical conduit from the header to the first box. Cut conduit to size and install between header and first box.
Repeat this procedure between the first and second box if applicable. Locate the liquid line solenoid valve provided with the
retarder kit and install a conduit connector. Stretch a reasonable length of conduit (approximately 48”) from the last
connection box to the liquid line solenoid valve. Connect conduit between the last box and the liquid line solenoid valve. See
“Fig: Wire covers and conduit installation for evaporator and condenser” on next page.
Step 4:
Feed the evaporator fan wires through the ceiling and onto the top of the retarder/proofer. Be sure that these wires are
secured in the evaporator so that normal servicing will not put tension on any wire going through the ceiling. Feed the 18
gauge wire provided through the conduit and connect to wires 16 and 18 in the header. Connect one wire from each
evaporator fan and one wire from the liquid line solenoid to wire 16 in each electrical box cover. Connect wire 18 to the other
evaporator fan wire in each connection box and at the liquid line solenoid. See drawing # 61124-08 on page 51.
Note: Evaporator fans and the liquid line solenoid will both function at the same time.
Step 5:
Screw both ends of the electrical connection boxes to the ceiling. Reinstall the cover on the liquid line solenoid connection
box. Reinstall the cover on the header. See “Fig: Wire covers and conduit installation for evaporator and condenser” on next
page.

Step 6:
Units with local condensing unit only:
Place the condensing unit on top of the retarder proofer. Locate the condenser so that the refrigeration lines will easily
connect with the evaporator inside the retarder/proofer. Be sure that there is ample space around the condenser to allow
airflow at temperatures less than 90º F. Allow adequate space for air discharge to prevent air discharge from recycling
through the fan. Anchor the condenser to the top of the retarder/proofer through the mounting holes in the base.

Step 9:
Before the refrigeration system is connected and charged, check electrical power, water and drain to the retarder/proofer.
Turn on the retarder proofer and operate in normal operation (see proofer installation instructions and installation start-up and
training check list).
Turn on the “Hold” or “Retard” functions and verify the following:
• Both evaporator fans operate while the retarder is cooling.
• The liquid line solenoid valve is activated when the retarder is cooling.
• Both the evaporator fans and the liquid line solenoid turn off when the retard temperature is set above the actual
temperature.
Turn on the “Proof” or “Rest” functions and verify the following:
• The climitizer fan turns on and stays on after the first call for heat.
• The evaporator fan turns off when the climitizer fan turns on.
Have refrigeration technician hook up refrigeration system.
Step 10:
Set the control clock to the correct day and time. Refer to the retarder control operating manual for set-up and operation
instructions. Be sure to arrange for training the operator on programming and use.

INSTALLATION
Instructions for assembling, inspecting, charging and testing the refrigeration
system:
Must be completed by certified refrigeration technician.
5 Steps:
Verify that the retarder proofer is assembled and that the evaporator is installed per the first half of these instructions.
Unless otherwise noted or requested, this retarder/proofer is designed for use with R404a refrigerant. Throughout assembly
and inspection, reasonably accepted practices should be used in conjunction with the refrigeration system. If you have any
questions or concerns please the Factory or the local supplier of the provided components.
Units with local condensing unit:
See “Table: Condensing Unit Electrical Specifications” on previous page for condensing unit specifications
Step 1:
Condensers rates at ½ hp and less need a pressure switch to control the condenser motors. If not previously installed, install
switch in the suction line Schrader valve and connect the wires to the condenser electrical box per the condenser
manufacturer’s schematic. Condensers equipped with adjustable pressure switches should be set at approximately 50 PSIG
cut-in and 30 PSIG cut-out for a low minimum system temperature of 20 degrees F.
See Drawing No: 61124-08 on page 51.

Note: The condenser is pre-charged with refrigerant ample for the condenser.
Additional refrigerant will need to be added once the refrigeration piping is installed, tested and evacuated.
Step 2:
Connect electrical power to the condenser per the condenser manufacturer’s instructions. Note: the condenser requires a
separate power supply from the retarder/proofer circuit.
INSTALLATION
Instructions for all retarder/proofers
Step 3:
Piping
: Refrigeration components are thoroughly cleaned and capped by the manufacturer of the component. Take care to
keep these sealed and as free as possible from moisture.
Step 4:
Install the expansion valve in the evaporator(s) in a position that will allow for adjustment of the evaporator superheat.
Verify that the expansion valve is the correct size for the evaporator load (see parts list). Install the sensing bulb in
accordance with the instructions provided with the expansion valve(s). Secure the capillary line so that it can not be damaged
while servicing the evaporator.
Notes to refrigeration technician
Connect liquid line using copper tubing sized to match the solenoid valve provided.
If two evaporators are provided reduce line size to ¼” at the tee connection on the top of the unit.
Insulate the return suction line to provide compressor cooling. Be sure that the resulting compressor superheat is
between 25º and 40º F.
Adjust expansion valve to obtain 8º to 10º F of evaporator superheat. Obtain the superheat by measuring the
discharge temps at the TXV and the evaporator.
