Megohm precheck
During shipping and/or storage, the possibility of absorption by the insulation material
within the element is possible. To ensure proper megohm values a minimum 500 VDC
megohm meter (Megger) should be used to ensure that the megohm reading between the
heater terminal and the heater sheath is more than 10 megohms when the unit is at room
temperature.
If several units are interconnected, the megohm of the heater is obtained by taking the
reading and dividing by the number of interconnected elements. This reading should be
greater than 10 megohms.
If a low megohm value exists, two alternative methods can be used to remedy the situation.
The best method is to remove all terminal hardware including thermostat if provided,
and bake out the heater at no higher than 250°F (120°C) overnight or until an acceptable
reading is reached. The second method is to energize the unit at low voltage in air until the
megohm is at an acceptable reading. Care should be taken to prevent the heater sheath
from exceeding 750°F (398°C) for Incoloy® and steel elements and 400°F (204°C) for coper
elements. Both of these methods should be performed with the heater out of the tank. The
