ACCESSORIES - HPC800 PROOFING CABINET
The HO300 Mini Rotating Rack Oven can be ordered with the optional HPC800 Proofing Cabinet. The
proofer is mounted on four casters (two front-swivel and two rear-fixed).
The HPC800 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. Temperature and humidity can be set independently to meet your
particular proofing needs. Air is circulated continuously to provide positive movement from bottom to
top, creating a uniform distribution of warm, moist air.
All HPC800 Proofers have easy-to-clean stainless steel interior and exterior panels with urethane foam
insulation.
PLUMBING CONNECTIONS
WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY
AND PLUMBING CODES.
The proofer should have its own water supply line, separate from the oven.
The proofer water supply should have a hardness of 4 to 6 grains per gallon, pH of 6.5 to 8.0 and
chlorides less than 30 PPM. Water condition outside of these requirements may void the warranty.
Please consult your local water company and/or water condition dealer before installing proofer.
Connect the cold water supply to the 3/8" NPT incoming water connection, located at the rear of the
proofer. Water supply should have a pressure of 30 to 75 psi.
DRAIN CONNECTIONS
Connect a 1/2" drain line to the 1/2" NPT drain connection located at the rear of the proofer. Route the drain
line to a floor drain, allowing a minimum 1" air gap between the drain line outlet and floor drain.
Provide a vent opening in the drain line above the oven drain connection location.
