Product Description
Wiring
Check type and voltage on nameplate.
Type 300 (120/240V AC only) single phase
Type 300 (240/480V AC only) single phase
Note: 120/240 volt models are wired at the factory for 120 volts. For 240 volt use,
change heating element jumper connections. Refer to wiring diagrams.
240/480 volt models are wired at the factory for 240 volts. For 480 volt use,
change heating element jumper connections. Provide a plug of the corresponding
voltage rating for connection to the power supply. Refer to wiring diagrams.
Grounding
The 120/240 volt ovens have a three blade plug with grounding prong (NEMA
5-15P) attached to a 10 foot power supply cord. When used with a grounded
receptacle, these ovens meet all local electrical code requirements and are ETL
listed.
The 240/480 volt ovens have a 10 foot power supply cord. When used with a
grounding plug and a grounded receptacle, these ovens meet all local code
requirements and are ETL listed.
Amp Draw
Ovens operating on 120 AC voltage draw 8.3 amps. Those operating on 240 AC
voltage draw 4 amps. Those operating on 480 AC voltage draw 2 amps.
Accessory Note
A Door Mounted Thermometer
(part #1250300) is available for
Type 300 Series ovens and can
be easily installed in the field.
Factory installation is available
with original order (see chart on
cover). This thermometer indicates
internal temperature range of
100˚ to 700˚F with an accuracy
specification of +/-10˚. Product
accuracy testing is conducted using
standards traceable to the N.I.S.T.,
USA.
Accessory Note
Stacking provision for Type 300
ovens is available with original
order. Stacking permits two Type
300 ovens to occupy the same floor
space as one. For each stack, only
ONE oven needs to be ordered with
the stacking lugs. Stacking lugs
(factory installed only) on lower
oven bolt to feet of any Type 300
oven, whether in the field or newly
ordered.
Electrode Placement
DryRod ovens have divided shelves to allow storage of more than one group of
electrodes. It is recommended to store different electrodes in separate ovens to
avoid contamination. Spread the electrodes evenly, allowing space over each shelf
for air circulation required to remove excess moisture. The maximum suggested
layer depth on any shelf is 5 inches.
Temperature Settings
Temperature range is 100°F (38°C) to 550°F (288°C). The thermostat dial (at rear of
oven) is calibrated from 100° to 550°F. Obtain required oven temperature setting
by rotating dial to line up desired temperature with indicator light in the thermostat
housing.
The indicator light illuminates only when voltage is being applied to the heating
elements. Momentary rotation past desired temperature setting may be necessary
to activate the indicator light in order to locate it for indexing purposes.
Thermostat is accurate to +/-25°F (14°C) at the sensing bulb; however, temperature
may vary slightly at different areas in the oven chamber because this is a
convection type oven.
At the maximum setting, the actual temperature in portions of the oven near the
heating elements may reach approximately 660°F (349°C).
Temperatures over 550°F (288°C) are not recommended. They may cause oven
damage and/or unacceptably high exterior surface temperatures.
Venting
For normal holding operation, set easily adjustable vent on the door about ¼ of the
way open. For replacement vents, see Replacement Parts section in this manual.
Guide to Storage
Electrodes should be stored according to electrode supplier recommendations.
In the absence of storage information from your electrode manufacturer, please
reference Phoenix's Guide To Electrode and Flux Stabilization for approximate
temperatures, found at www.dryrod.com/guide.

CAUTION
• To provide continued protection against risk of electrical shock, power
cord must be connected to a properly grounded outlet.
• To avoid damage, never place oven in contact with welding current.
• Store in dry location. Unit not to be exposed to rain or moisture.
