Master electronic 1073.090

Roger,

I just purchased this and I beilieve it dropped shipped from you the other day. I have a couple questions.

Both connections are threaded with an O-ring at the base. Will a standard US 1 1/2 threaded union work with these or is there a special conversion to go to US 1 1/5 pvc?

I was reading in the documents that this pump can be submerged. Is this true and OK for saltwater? Also if it's safe, how much heat will it put off?

Thanks
Tony (Anthony)

This one can be submerged- even in saltwater. The bigger ones cannot due to an aluminum heat sink. It is standard 1.5" PVC. I couldn't tell you exactly how much heat it would put off, I could guess 4 degrees per 100 gals. That is only a guess based on what other pumps of similar wattage do.

Roger, I dry fitted by hand the threaded 1 1/2 unions and they do not want to go all the way down. Actually stop halfway. Is this a problem?? Especially if I decide to go external? Also do you know how much the temp, if any, rises if used extenal? Just going thru my options here.

Lastly, if I go internal. Are there suction cups or a pad for the pump to rest on since my sump is glass?

There are no pads or cups and I would recommend external mount. I think the union probably has a slight pitch to the thread. If you used some teflon tape or paste it should be OK. In testing them I used a thread to slip adapter from Lowes and that did screw down all the way but some fittings and some brands have a taper and will only thread on so far. I can only guess the heat increase, it is a 150watt pump Approx and that is going to produce some heat, no way around it. I think the difference between submerged and external will be nominal, it is a water cooled pump some heat will dissapate into the air but since it isn't air cooled it won't be a huge difference, maybe .5 degrees.
