I have a 1 1/2 hp Flotec model #AT 251501--failry new--when hooked to pool ( 1 1/2 lines ) on 220v hookup--does not build up full pressure--water surges & never fills trap up full. When I replace with a 1HP Starite maxiglas-everything works fine. I bought the Flotec used & checked out the Impeller ect. all appears fine. Was replacing the Starite which I wanted to use on a spa. Any suggestions for the problem with the Flotec ??

Re: low water flow
Sounds like air is trapped in the system somewhere. that is why any pump will surge. check the lines going in to make sure it isn't sucking air somewhere along the way and make sure the discharge line is clear so it can pump out fully.

You can check the inlet line where it comes from the pool... Their is a little sreening/filtering system in the the parts that screw together and connect the valve to the pool... When I unscrewed mine, it was jammed with bugs, leaves, green algea... That did the trick for me... I am sure you already changed/cleaned the filter in the filter/pump that comes before the Salt water system... That will cause low flow as well...
your pump should be just fine once the water starts flowing again. You may have run it too long without enough water to cool the seal. If it is leaking water between the Jacuzzi Pump housing and the motor then you will need a new pump seal. Those are common pool parts.
Yes you can. The saltwater chlorinator is connect to the outlet water pipe from the sand filter before the water returns to the pool. Depending upon the model of the saltwater chlorinator It may need to be mounted horizontally or vertically, check with the installation instructions..
this pump needs about 21/4" of water to operate properly, this pump will not remove all the water from the cover and will cycle on and off as it looses prime. If the motor turns completely off, it may be a an issue with low line voltage. you can try using a lager gauge extension cord to try and fix it, otherwise have an electrician test the line voltage.
Here is a pdf of the manual: http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000049529.pdf
Code 90 is supposed to be indicating there is a low or no water flow condition. I have had this happen when my filter got dirty and it's water flow was reduced and when the electrolytic cell had a lot of deposits and blocked too much of the flow.
The water flow is detected by the flow sensor. The flow sensor is contained in the tube located immediately behind the square transformer housing. It has a cord coming out of the top of it.
Make sure your water is flowing in the correct direction. It should flow in the right side of the 8110 and out the left side of it. If you detach the hose on the right side of the unit, you will see a small basket which is supposed to catch debris before it can enter you electrolytic cells. Make sure this small basket is clean. After the basket is the actual flow sensor. It has a paddle hanging down which gets deflected up as the water flows through the tube. Make sure the paddle pivots freely and does not have any kind of build-up on it. After the flow sensor is the electrolytic cell. If the space between the plates has a lot of build up you will need to clean the plates (I pressure was them).
1. If your filter hasn't been backwashed, that's a good place to start.
2. If you haven't done a seasonal disassembly and washout of your filter, that will allow a residual to build up and keep your flow low.
3. The control selector valve...you may want to open that up and make sure there's no blockage in there as well... only as a last resort.
4. Also, remove the basket in the pump and reach in to the intake port and check for debris...that'll do it too.
Let me know if you get the pressure back up!
