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 oor drain, allowing a minimum 1" air gap between the drain line outlet and oor drain.
If oven is being installed on an MB300 Proong 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 ood the proofer cabinet.
ELECTRICAL CONNECTIONS
Electrical and grounding connections must comply with the applicable portions of
the National Electrical Code and/or other local electrical codes.
Disconnect the electrical power to the machine and follow lockout / tagout
procedures.
Appliances equipped with a exible 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 OV310G gas model to the electrical supply until after gas
connections have been made.
The OV310E 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
Volts Hertz Phase Amps
208 50-60 3 50
240 50-60 3 43
480 50-60 3 22
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 MB300 Proong Cabinet, a separate 120 V supply is required for
the proofer.
