Product Description
Wiring
Check type and voltage on nameplate.
Type 900 (240/480V AC only) single phase
Note:
240/480 volt models are wired at the factory for 240 volts. For 480 volt
use, change heating element jumper connections. Provide a plug cap of the
corresponding voltage rating for connection to the power supply. Refer to wiring
diagrams on page 6.
Grounding
The 240/480 volt ovens have a 10 foot power supply cord. When used with a
grounding plug cap and a grounded receptacle, these ovens meet all local code
requirements.
Amp Draw
Ovens operating on 240 AC voltage draw 10 amps. Those operating on 480 AC
voltage draw 5 amps.
Accessory Note
A Door Mounted Thermometer
(part #1250300) is available for
Type 900 ovens and can be easily
installed in the field. Factory
installation is available with original
order (see chart on page 1). 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.
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.
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 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. Required oven temperature setting is
obtained by rotation of 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 as 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.
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
DryRod Type 900 Series ovens are designed to be holding ovens. For high
temperature baking ovens, see Phoenix DryRod Type 40HT Ovens.
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.
