OPERATION AND CARE OF
MB100/MB300 PROOFER
SAVE THESE INSTRUCTIONS
GENERAL
The MB100/MB300 Proofer cabinet proofs racks of dough product under controlled temperatures and
humidity prior to baking. The MB300 Proofer has a 16-pan capacity that accommodates 18" x 26" (45.7
cm x 66 cm) baking trays with 3" (7.6 cm) slide spacing. The MB100 holds 8 pans and can be used as
a holding cabinet. Temperature and humidity can be set independently to meet your particular proofi ng
needs. Air is circulated continuously to provide positive movement from bottom to top, creating a uniform
distribution of warm, moist air.
All MB100/MB300 Proofers have easy-to-clean stainless steel interior and exterior panels with urethane
foam insulation.
The MB100/MB300 Proofers are produced with quality workmanship and material. Proper installation,
usage and maintenance of the proofer will result in years of satisfactory performance.
It is suggested that you thoroughly read this manual and carefully follow the instructions provided.
INSTALLATION
The MB100/MB300 Proofer must be installed by authorized Bakery Systems trained service technicians.
ASSEMBLY
The proofer comes pre-assembled, but requires qualifi ed personnel to install and make connections. The
proofer must be installed with restraining means to guard against transmission of strain to the connector, as
specifi ed by the manufacturer. Adequate means must be provided to limit the movement of the appliance.
UNPACKING
This proofer was inspected before leaving the factory. The transportation company assumes full responsibility
for safe delivery upon acceptance of the shipment. Immediately after unpacking, check for possible shipping
damage. If the proofer is found to be damaged, save the packaging material and contact the carrier within
15 days of delivery.
Carefully unpack the proofer and place in a work-accessible area as near to its fi nal installed position as
possible. Remove protective covering from exterior surfaces prior to placing proofer in fi nal location.
