1. You want to make sure the pump is well below the level of the valve (actually below the liquid level) by a good amount (couple of feet).

3. Turn on pump.
4. Slowly open valve on pump suction. This valve should be connected directly to the pump discharge and not on tubing.
In order to get a prime, you may need a way to eliminate any vapor that may be in the pump and suction lines. But if you open the discharge valves before the pump is turned on, you will have a difficult time priming your pump and operating your pump at deadhead (zero flow) for a short period of time shouldn't cause any damage.
These are general operations that have been successful for me. I am sure those more familiar with March pumps (or similar) will chime in with their experience.
1. The pump is definitely below the valve and liquid level
2. So I should open the kettle output valve - I would have to open the valve on the pump as well to get the air out and let the BK drain to the pump correct? Then close it before turning the pump on?
3. Turn the pump on with the pump valve still closed, then slowly open it?
4. I don't have a discharge on my pump. I just have 2 hoses (with QDs) going to and from the pump.
Thanks for your help! I'm just a little confused about working this pump. It worked so easy for me going from HLT to MLT, then MLT to BK, but that was obviously a different scenario since it was draining into an empty vessel instead of one already full of liquid.
It sounds like I need to let liquid flow down to the pump, getting all of the air out of it, then hook it up the 2nd ball-valve on the kettle (while keeping it closed) then slowly open the inflow kettle valve while the pump is running.
I think for my next brew I'm going to use a hop-spider type setup to contain the hops while I'm still getting used to working the pump. Maybe eliminating one variable (hops floating around freely) will help.
Thanks again for the help!
