Do not store combustible material on or around the unit.
•
Do not operate this unit empty.

When using the unit at a distance where an extension cord becomes necessary, a 3-conductor
grounding cord of adequate size must be used for safety, and to prevent loss of power and
overheating. Use only a UL listed extension cord suitable for outdoor use. Make certain wire size is
large enough for A/C amperage rating of unit.
Installation
Remove wooden crating material from upper portion of oven. Pallet material is removed by
leaning oven slightly forward and backward, and removing bolts from underside using an adjustable or
socket wrench. When oven is free from pallet, place bolts back into oven legs for leveling. Oven should
be leveled with slight tilt to the back. Locate oven in an area free of flammable material and near
appropriate electrical source.
Operation
Load oven in an area free of combustible material and close to an appropriate electrical source.
(Check name plate for voltage.) Adjust leveling bolts on legs so that oven is level and tilted slightly to the
back. (Operator should read the enclosed “Controller User’s Manual” before placing oven in operation.)
Note: The controller is to be used in the “Proportional” mode.
Wire oven to a fused disconnect of proper voltage and amperage. Load oven with desired amount
of electrodes. Switch on power to oven. Set over temperature controller higher than temperature
controller’s set point. Adjust temperature controller set point to desired temperature. Refer to the
“Controller User’s Manual” for instructions in tuning controller. All units are supplies with a UL listed SJ
power cord and meet electrical code requirements when used with a grounded circuit.
***CAUTION: DO NOT USE ON D/C POWER SUPPLY!***
Venting
The KHT-900 oven is vented through two screened plugs at top rear of oven.
Temperature Setting
To adjust temperature set point press and hold the “Read Set PT.” Push button. The current set
point will appear in the digital display. Locate the “Set Point” knob beneath the door flap. Turn the “Set
Point” until the desired set point appears in the digital display. Release the push button. Digital display
will now read interior oven temperature. (Inserting a screwdriver in the set point knob and turning the
knob with the screwdriver may accelerate Set point adjustment.) Adjust over temperature controller to a
set point higher than temperature controller’s set point and press reset button.
Functional Description
These high temperature ovens are designed for rebaking electrodes. After the rebaking process is
complete, electrodes may be transferred to the job site, a holding oven, or stored in the high temperature
