OPERATION

 

1.Do not operate heater at voltages in excess of that stamped on the heater since excess voltage will shorten heater life.

2.Always maintain a minimum of 6 to 8” of liquid above the heated portion of the element to prevent exposure of the effective heated length. If the heater is not properly submerged, it will overheat and shorten heater life. DO NOT OPERATE HEATER IF DRY.

3.Keep heating elements above sediment deposits.

4.Low Megohm Condition — The refractory material used in elec- tric heaters may absorb moisture during transit, storage or when subject to humid environments that will reduce the cold insulation resistance (low megohm). Low megohm may result in a high leak- age current to ground and nuisance trips of ground fault protection equipment. Normally, the megohm value increases after heat-up. Typical insulation valves are 5 megohm or greater on complete

assemblies or 20 megohm on individual unsealed elements. It is recommended that heaters with 1 megohm or less be dried out before applying full power. If dried properly, low megohm will not effect heater life or efficiency.

To correct a low megohm condition, remove terminal enclosure cover, gaskets, and terminal hardware. Bake heaters in an oven at 300 to 500˚F for several hours or preferably overnight.

An alternate procedure is to cycle the heater in 10 to 15 minute periods at low voltage until megohm values are normal. Sheath temperatures should not exceed 350˚F.

NOTE: Low megohm on heating elements with epoxy or hermetic seals cannot be serviced in the field. Typical resistance val- ues when sealed are 200 megohm or greater. Contact Chro- malox service center at number listed.
