DRAIN CONNECTIONS
Connect a
1
/2" drain line to the
1
/2" NPT drain connection located at the rear of the oven. Route the drain
line to a floor drain, allowing a minimum 1" air gap between the drain line outlet and floor drain.
If oven is being installed on an HPC800 Proofing Cabinet, it is recommended that separate drain lines
be provided. If it is necessary to interconnect the oven and proofer drains, provide a vent opening in
the drain line above the oven drain connection location. Adequate drop must be provided such that the
oven drain will not flood the proofer cabinet.
ELECTRICAL CONNECTIONS
WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE
APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL
ELECTRICAL CODES.
WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AND FOLLOW
LOCKOUT / TAGOUT PROCEDURES.
WARNING: APPLIANCES EQUIPPED WITH A FLEXIBLE ELECTRIC SUPPLY CORD ARE
PROVIDED WITH A THREE-PRONG GROUNDING PLUG. THIS PLUG MUST BE CONNECTED
INTO A PROPERLY GROUNDED THREE-PRONG RECEPTACLE. IF THE RECEPTACLE IS NOT
THE PROPER GROUNDING TYPE, CONTACT AN ELECTRICIAN. DO NOT REMOVE THE
GROUNDING PRONG FROM THIS PLUG.
The wiring diagram is located behind the side service panel on the right side of the oven.
Do not connect the HO300G gas model to the electrical supply until after gas connections have been
made.
The HO300E is an electrically heated oven consisting of six W-shaped elements, each rated at 3.0 kW
for a total input of 18.0 kW. The electrical input is shown in the table below:
Heating Circuit Supply Voltage
Both gas and electric ovens require a dedicated 15-amp, 110 V 50 Hz or 120 V 60 Hz, single-phase
supply with ground, connected at the control circuit terminal block located behind the right side service
panel. If oven is installed in conjunction with an HPC800 Proofing Cabinet, a separate 120 V supply
is required for the proofer.
