Henkel KEEN OVENS K-450 - Manual (Page 4)

• 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.
Operation
Load oven with desired amount of electrodes. To turn on the unit, simply plug the power
cord into appropriate single phase A/C source and adjust thermostat to desired setting. (Check
nameplate for voltage.) The 120V units are supplied with a three conductor 8” power cord. The
240V and 480V units are supplied with an 8’ UL listed 16/3 SJ power cord (plug not provided).
All units meet electrical code requirements when used with a grounding plug and a grounded
receptical.
*** CAUTION!! DO NOT USE ON D/C POWER SUPPLY! ***
Temperature Setting
The thermostat is adjustable from 150ºF (37.8ºC) to 550ºF (287.8ºC). Turn thermostat
knob to desired temperature by aligning with red line on chrome bezel. Pilot light indicates when
power is supplied to the heating element. The thermostat is accurate to ±23ºF (14ºC) at the
sensor. Temperature variance is minimal throughout the oven due to the heat exchanging
qualities of the Keen shelving system.
** CAUTION!! Surface temperature of heating element will exceed 500ºF.
Electrodes adversely affected by high heat should be stored on upper shelves of oven. **
Guide to Storage
See the enclosed guide to storage. This guide may be used in the absence of storage
information from the electrode manufacturer. In critical situations, contact your electrode
manufacturer.
Functional Description
These models are designed for the small to medium shop. They allow storing at optimum
temperature, protecting electrodes from harmful moisture. These ovens are compact and energy
efficient, therefore an economical buy. All bench types are thermostatically controlled. The shelf
design accommodates 50lb. electrode containers eliminating the need to remove the rods from
the container. Loose electrodes may also be stored in shelf compartments.
