Coolant Contactor

[jttoner]

I ordered Tormach's 25A coolant contactor. Now, reading the owners manual I see there are two contactors Nos. 12,13, both with the same part number. I can't find out which is for the coolant motor. To make matters worse, now I learn that there is an external contactor upgrade kit. All I ordered was the contactor hoping it would be a plug in replacement for the original. Also, I've searched this forum, Google, and YouTube for instructions on replacing the contactor and came up with nothing.

If they have the same part No. wouldn't they be identical parts?
A contactor generally is not a complicated device.

True, but each might be for a different circuit.

I'm confused, if you order a replacement contactor you know what circuit it is for??
I would have to assume if they are identical part Nos. they each have the same function, regardless of where they are used?

It appears I ordered the wrong part. I intended to buy the 25 A contactor for the coolant part. I'll eat that one and reorder tomorrow.

A 25amp contactor will run a 120v 3hp-4hp motor, That must be one heck of a coolant pump!

I believe in flood cooling by way of nearly Biblical scale flooding

jttoner,

What pump are you looking into? I'm nearly complete with my coroplast/lexan full enclosure and now I'm looking into upgrading the flood coolant. I've been following this youtube video but I'm starting to think biblical flooding is the way to go.

Thanks!

Be verrrrry careful with that kind of container as a coolant reservoir.... Some of those translucent rigid storage containers are made of plastic that becomes brittle over time, and can literally shatter into pieces with little warning. You don't know what a mess is until you've had 15 gallons of soluble oil-based coolant flood your shop. The more "rubbery" plastics, like the Rubbermaid brand containers, are MUCH less likely to fail.

Good info Ray. Makes sense being that the curtains on my "shower curtain enclosure" only last about 1 year and they become brittle and crack. ($5 clear shower curtains from the hardware store)

Thanks for the heads up Ray. I couldn't imagine that mess so I'll look into the Rubbermaid.
