Be sure your original NAPCO 704-7000 heaters are defective before replacing them by performing
the following test
Testing The NAPCO 704-7000 Heating Elements
This test consists of measuring the amount of
resistance in the element. To do this, first, turn the autoclave off
and unplug it from the wall
WARNING: CURRENT MUST NOT BE PRESENT WHEN MEASURING RESISTANCE.
Set your volt/ohm meter on 200 ohms (200 NOT 200k). The ohms range is located within the Omega (Ω
)(look for this
symbol) section of your meter. It is also the area with "k" ranges (ie: 2000k,. 200k, 20K and then 2000, 200).
Place a probe from the volt/ohm meter on each wire where it connects to the element (it really doesn't matter which
color probe goes where).
|For the heating element to be good, it must fall within the resistance range in this table (between 10.37 and 12.67 ohms) If your reading is outside of
this range, then it is defective and needs to be replaced.
||10.37 ↔ 12.67 ohms
