Henkel K-900 - Manual (Page 5)

Temperature Setting
The thermostat is adjustable from 150
°F (37.8°C) to 550°F (287.8°C). Turn thermostat knob to
desired temperature by aligning with red line on chrome bezel. Pilot light indicates when power supply is
supplied to the heating elements. The thermostat is accurate to
±25°F (14°C) a the sensor. Temperature
variance is minimal throughout the oven due to the heat exchanging qualities of the Keen shelving
system.
***CAUTION: DO NOT USE ON D/C POWER SUPPLY! ***
Venting
The models K-900 and the K-1000 ovens are vented through two screen plugs at the rear of the oven.
*** CAUTION: SURFACE TEMPERATURE OF HEATING ELEMENTS WILL EXCEED 550
°F.
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 to hold large amounts of electrodes at moderate optimum
temperatures providing protection from harmful moisture. The unique diagonal shelf design allows the
storage of 50lb. electrode containers eliminating the need to remove rods from containers. The individual
shelf compartments also facilitate the storage of different type rods in the same oven without disorder.
Scheduled Maintenance
The manufacturer recommends that the unit be unloaded and cleaned of debris and dust every six
months. It is also recommended that a temperature probe be placed inside the unit and the thermostat
calibration checked at this time.
Troubleshooting
The Keen oven models K-900 and K-1000 require a minimal amount
of electrical knowledge to repair if necessary.
