Testing new pump and filter

[domct203]

I've recently took advantage of the crazy price at Amazon and bought a new 1.5HP Hayward pump & 21" sandfilter. Next spring I will need to create a proper equipment pad for this much larger system.

I would like to at least try the filter and pump this weekend before I close the pool to make sure everything works and there are no defects. I do not want to add the 200lbs of sand as I will need to move this filter to pour a slab in the spring, then move it back onto the pad for opening.
Are there any concerns with running the sandfilter empty? I know that centrifugal pumps work easier if there is back pressure on the pressure side, I planned to close the return valves a bit to simulate the backpressure experienced with a sand-filled filter.

I only plan to run for 5-10 minutes this way.

Anything I should be concerned with? Will this damage anything?

Thanks.

I don't know anything about running a sand filter with no media in it. The only thing I can think of is that it might blow the laterals off and damage them. So, maybe enough sand in the bottom to keep it all together?

I was worried about the laterals as well. I am thinking of leaving the entire stand pipe/laterals assembly out. I'll manually fill the filter with water too.

That sounds good. Just to test the valve and make sure the housing doesn't leak.
