OVEN DESCRIPTION

WIRING

Identify type and voltage on nameplate.

• Type 300, Models 16C & 16CST (120/240V AC only)

single phase

• Type 300, Models 15D & 15DST (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.

A laminated version and poster size version of the Guide To
Electrode and Flux Stabilization is available by contacting

Phoenix International, Inc.

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.

TEMPERATURE SETTING

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 since 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).

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.

GUIDE TO STORAGE

Electrodes should be stored according to electrode supplier
recommendations. In the absence of detailed storage
information from your electrode manufacturer, the Guide To
Electrode and Flux Stabilization section in this manual may be
used as an approximation of temperatures.

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˚.

Temperatures over 550°F (288°C) are not recommended. They
may cause oven damage and/or unacceptably high exterior
surface temperatures.

REPAIR: SPARE PARTS

These instructions contain wiring diagrams and a repair parts
list for your DryRod oven. For critical welding operations
requiring continuous holding, we would suggest carrying all the
parts listed in the Suggested Spare Parts section of this manual.

(Spare parts are available at www.phx-international.com or by
contacting your local distributor.)

HEATING
ELEMENT

OVEN FAILS TO OPERATE: NO HEAT/OVERHEATS

1. If the indicator light does not illuminate, check power supply.

2. Check plug at outer end of power cord and run continuity

check on complete power cord. If defective, replace cord
assembly.

3. Check indicator light for continuity. If defective, replace
indicator light.

4. Check thermostat at rear of oven. If indicator light
illuminates, power is being supplied through thermostat
to dual heating elements. Turn knob from low to high
setting and return. Definite “snap” should be heard at
low temperature end and indicator light should turn off
and on with each “snap” cycle. If “snap” is not heard and
indicator light fails to operate, replace entire thermostat. (See
Replacement Parts section in this manual.)

5. If thermostat operates satisfactorily, check continuity of
dual hairpin style heating elements at bottom center of oven.
Failure of one element will prevent oven operation on 480
volts. If operating on 120 or 240 volts failure of one element
will cause very slow heating.

6. If thermostat operates satisfactorily, recalibrate thermostat.
(See Checking Thermostat Calibration section in
this manual.)

TROUBLESHOOTING

DOOR WILL NOT CLOSE PROPERLY

1. Use screwdriver to adjust door latch.

2. If latch is broken, replace with Door Latch & Strike (Part

#1252200). (See Replacement Parts section in this manual.)

NOTE:

When replacing heating elements, always
replace both elements. Pairing of one new
element with an old element will cause
rapid failure of old element.

Type 300 Series Electrode Stabilization Oven

CHECKING THERMOSTAT CALIBRATION

Each thermostat is adjusted at the factory and calibrated on precision instruments to control temperatures
accurately. Adjustment or re-calibration is not needed unless the thermostat has been mishandled in transit
or changed or abused while in service.

To Check Calibration:

1. Use a high grade mercury thermometer to check
temperature. For griddle control, use a disc type
thermocouple. Drop a couple drops of oil on
griddle surface plate and place thermocouple disc
flat into the oil.

2. Turn the dial of the thermostat to the 325˚ mark.

3. Allow enough time for temperature to stabilize or

until several temperature readings are identical.

To Calibrate:

1. Remove knob from dial shaft by pulling knob
straight out.

2. With screwdriver, turn screw clockwise to decrease
and counter-clockwise to increase temperature. Do
not allow dial shaft to turn during this operation.
A 1/4 turn of the screw equals approximately 35˚.

3. Replace knob or control dial.

4. After calibrating, let the appliance operate until

the temperature has stabilized, then recheck to
determine if the calibration has been successful.

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.
