Running D5 without coolant

[reaper7534!]

I assume this isn't a issue since it wasn't prolonged, just want to verify. I receeived a Photon 270 w/ D5 Vario and wanted to check it before everything is set up. I plugged it in briefly.....maybe a second if that. The pump works but just made a hell of a noise, squealing sound. I'm assuming this is from lack of fluid and will be fine when filled.

So I should just run with it I suppose ?

Yes

I feel like I've heard numbers like running dry up to 10 seconds or so is possible before killing the pump.

You are probably OK with one second. Just don't do it again. Running a pump like this dry is the fastest way to kill it.

Figured as much. I'll be building Thursday night as soon as I get the rest of the goodies from Performance PCS

Yeah, not great for ceramic bearings. Give it some fluid.

I always add some hose to the inlet and outlet and use some tap water to test it.

Before staring, put the pump under the water level of your bucket, and suck some water into it. If you then turn on the pump, it is in normal operation and cycles the water through your hose and bucket.

Don't run it dry.
