How To Test & Replace The Pelton Crane HP Autoclave Heating Element(s)
Thursday, October 22nd, 2009If you are experiencing heat related problems with your Pelton Crane HP Autoclave, the odds are pretty good you have a faulty heating element. Here is how to know for sure
The Pelton Crane HP originally had 2 heating elements, rated at 800 watts each. Testing them is simple and something you can do.
How To Test The Original Pelton Crane HP 800 Watt 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.
You will need a volt/ohm meter to conduct this test. The volt/ohm meter doesn’t have to be anything fancy or expensive. You can get one for less than $20.00 from Walmart, Lowes, Home Depot, etc
Disconnect the wires from the Pelton HP autoclave heating elements so you don’t get a false reading. Mark the wires so you know which wire went where, so when you complete the test, you can hook them back up correctly and quickly.
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).
It doesn’t matter which color probe goes where. Be sure to test both elements.
The range you are looking for is 16.2 – 19.8 ohms. If the readings on your elements are outside of this range, then they are faulty and need to be replaced.
The original 800 watt heating elements on the Pelton Crane HP Autoclave have been replaced with a single 1600 watt element. So, even if just one is bad, you will need to remove and discard both of them.
But don’t do it just yet. Leave them connected until you have the new HP replacement heating element in hand. This will greatly simplify the installation process and eliminate any confusion over the wiring of the new element
And, don’t be confused when connecting the wires to the new element. The old elements had 4 wires and the new element has only 2 terminals. Simply look at it as though the second element didn’t exist.
The two wires on the left become a single wire on the left and the 2 wires on the right become a single wire on the right
Your Pelton Crane HP Autoclave is a true classic, and you have just added a few more years to it’s life !
