Product Description
Installation
This oven was crated and packaged for long-distance shipment. Exercise care in
removing the oven from the wooden crate.
After oven is in final location, anchor as required, open the oven door and remove
packing material, manuals and loose parts.
Wiring
Check type and voltage on nameplate.
750HT (3/240V AC only)
750HT (3/480V AC only)
For 240V Wiring
Connect to a 240V, 50/60 cycle, 3 phase power source. Conduit openings (1/2")
are provided in the wiring compartment for this purpose. A three-pole disconnect
switch should be provided since there is no power switch in the oven itself. Use
30-amp fuse. A schematic diagram of internal wiring follows.
For 480V Wiring
Connect to a 480V, 60 cycle, 3 phase power source. Conduit openings (1/2") are
provided in the wiring compartment for this purpose. A three-pole disconnect
switch should be provided since there is no power switch in the oven itself. Use
15-amp fuse. A schematic diagram of internal wiring follows.
Amp Draw
Ovens operating on 240 AC voltage draw 25 amps. Those operating on 480 AC
voltage draw 12.5 amps.
Grounding
The 750HT ovens have a grounding lug in the upper control box.
Operation
1. A. Start-up (switch in “OFF” position)
2. Turn on power to the oven.
3. If red light is on, push the reset button to reset high limit control.
4. Set temperature controller at desired temperature by pressing the UP/DOWN
keys and then pressing ENTER.
Description of Controls
The controller in this oven is a full-indicating, PID (proportional, integral,
derivative) controller using a Type J thermocouple sensor. The controller is
factory set for optimum performance accuracy with a 400 pound load at
maximum temperature.
The high-limit control is a mechanical device with on-off control action. The
high-limit control will shut down the oven heat when the oven temperature
reaches the high-limit set point. In order to regain power to the heating
elements, the oven must cool down below the high-limit set temperature.
Controller
If any adjustments are required, they should be done by a qualified person with
the aid of the instructions contained in this manual or the Original Factory Setting
Guide (available upon request from Phoenix International). All instruments are
fully tested and adjusted for optimum performance prior to shipping the oven. If
the settings are lost for some reason, contact Phoenix International for the PID
Controller Original Factory Setting Guide.
Temperature Settings
Excess Heat: At maximum setting, the actual temperature in portions of the oven
near the heating elements may exceed the upper range.
Guide to Storage
Flux should be stored according to flux 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
• Disconnect power and make sure oven is cooled before opening
or servicing unit.
• Hot Surfaces! Use extreme care to avoid possible burns or personal injury.
Protective gloves and personal protective equipment are recommended.

For users of large DryRod oven quantities or users not in North America:
For normal daily operation, the following spare parts and quantities are
recommended to have inventoried.
Oven Fails To Operate: No Heat
1. If the indicator lights and controller do not illuminate, check power supply.
Manual reset of the high temperature limit switch may be necessary.
2. If indicator lights still do not illuminate, check indicator lights for continuity.
See Repair Parts drawing for access details. If defective, replace indicator
lights.
3. If power is being supplied to the oven, but not the controller, check the
transformer.
4. If power is being supplied to the controller, but there is no heat, check the
relay, contactor, switch and high limit control for proper operation.
5. If proper voltage is being supplied to the oven and all other equipment is
functioning properly, reset the controller and reprogram with factory settings.
6. If controller, switch and contactor operate satisfactorily, check continuity of
heating elements. Failure of one element may cause slow and/or uneven
heating.
7. Remove oven from power source. Replace all elements.
Oven Operates: Overheats
1. Check controller operation as in Step 4 (Oven Fails to Operate: No Heat).
2. Check contractor, relay and wiring.
Oven Operates: Temperature Setting
"OFF"
1. Check contractor, relay and wiring.
2. Check controller operation as in Step 4 (Oven Fails to Operate: No Heat).
CAUTION
• When replacing heating elements, always replace both elements. Pairing
of one new element with an old element may cause rapid failure of old
element.

Controller Programming Instructions
Initial Setting
From the initial setting menu temperature, units, control mode and ramp/soak
operations can be accessed. To access initial setting mode, press and hold the
ENTER key for at least three seconds. Parameters can then be cycled through by
pressing the INDEX (loop) key.
Select Input Sensor Type
Access initial setting menu until PV line displays InPt, press DOWN arrow until J is
displayed, press ENTER to accept setting. After changing input sensor type, you will
be returned to the main screen.
Select Temperature Unit
Access initial setting mode and press INDEX key until PV line displays tPUn. Press
UP/DOWN arrows until desired unit is selected. Press ENTER to accept change.
Control Mode
From initial setting mode press INDEX to CtrL. Default from factory is ON/OFF
control mode. Ramp/Soak profiles can be accessed here as well.
Heat/Cooling Mode
This selects heating or cooling operation. Set to HEAT.
Alarm Settings
Up to three alarms may be set for various conditions.
SALA
The System Alarm Setting selects which alarm output is used if a system alarm
occurs. The system alarm would be in Input Error or Process Control Failure. This
feature can be disabled by turning this parameter to off.
The following set of functions deal with RS-485 communications and can be found
in the controller operating manual. For the full controller manual, please contact
Phoenix International.

How to Set Temperature
If temperatures are not displayed, press ENTER key. The top line displays the
Process Value or the current temperature inside the oven. The bottom line displays
the Set Value or the desired temperature setting. To change the Set Value, press the
UP or DOWN keys until the desired temperature is displayed and press ENTER.
Security Features
The controller has two built-in security locks to prevent unauthorized personnel
from modifying parameter settings.
The LoC1 setting affects all parameters of the controller. If LoC1 setting is enabled,
the operator will have to unlock the controller to make any changes to the
controller parameters.
The LoC2 setting affects all parameters with the exception of the set point. If LoC2
setting is enabled, the only parameter that the operator will be able to change is
the set point. In order to change any other parameters, the operator will have to
unlock the control before making a change.
To unlock the control, the operator must depress the ENTER and INDEX keys
simultaneously.
To access the Lock control setting, press the INDEX key twice from the main
temperature display.
NOTE
• Unit is shipped with controller programmed for single temperature (in
degrees Fahrenheit) operation. Up to 8 ramp/soak control programs are
able to be programmed.
• Please see included insert for ramp/soak programming details

This guide explains proper storage and oven holding temperatures:
• Recondition/rebake procedures for electrode coatings exposed to moisture are included.
• Remove electrodes from cardboard containers before placing in ovens.
• Electrode coatings should not be exposed to the re-baking temperature without first being reconditioned at a lower temperature. Failure to do so may result
in breakdown of electrode coatings. After re-baking, lower temperature to holding level until reissued.
