Henkel K-450 manual Operation, Temperature Setting, Guide to Storage, Functional Description

•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.
