So I just installed my new VS Pump (Hayward SP2602VSP) and I have a couple general questions:
1. I see in the manual there is a table that gives a maximum flow rate based on pipe size. I have 2" piping and the table says the max flow rate is 80 GPM. Does this mean that at the full 3,000 rpm speed the pump will do 80 GPM? If this is the case, can I assume that at 1,500 rpm the pump will do 40 GPM?
2. My old pump was a Hayward 1HP SuperPump and I would run it for about 13 hours a day. I have figured out the speed I need to run the pump on for my salt system to work (about 1700 rpm). Should I run the pump at 1700 rpm for the same 13 hours I used to run the old pump?
3. The SP2602VSP has a built in timer system that lets you program when you want the pump to run and at what speed. With that, I would think that an external timer system to turn the pump on and off is not needed. Is there something that I am overlooking that would call for the separate external timer?
