We are now going to disconnect the wires to the old pool pump. If you are uncomfortable with working with electricity, contact a licensed electrician for help in disconnecting and reconnecting the pool pumps. You can hurt yourself or damage the pump if you are unsure about what you are doing. Remove the two screws that hold the cover onto the end of the motor. Remove the cover.
This is a picture of the wiring on the old pool pump. Since the new pool pump is equivalent to the old pool pump, you will want to wire the new pump exactly like this. The first thing to see is that this pump has been wired for 230 V and not 115V. The white arrow on top of the 2 prong black plug is pointing at 230V. Three wires are coming to the pump from the circuit box: red, black and green. For 230V both red and black are load wires, there is no neutral. In this case red is going to the L1 terminal and black is going to the L2 terminal. The green wire is ground and is secured under the green screw to the far right.
Take the three in-coming wires (green, red and black) off their terminals.
Your next step is to identify where you have to cut the piping to remove the old pool pump.
Cut the pipe on the discharge side of the pump.
Lay the new Pentair Intelliflo pump where the old pump was. We want to hook up the suction side of the pool pump first so we know exactly where the new pump will be positioned.
Our first fitting will be the one connecting the pipe to the pool pump on the suction side. This pool had 1.5" plumbing so this fitting has 2" threaded end and a 1 1/2 slip end. The threaded end screws into the pool pump. To seal this joint, use Teflon tape. Make sure the fitting is thoroughly cleaned. When applying the Teflon tape to the threads, wrap the entire threaded portion of the male fitting with two to four layers of tape. Wind the tape CLOCKWISE as you face the open end of the fitting, beginning at the end of the fitting. DO NOT use Plumber's Pipe Dope.
Once the fitting is threaded into the intake of the Pentair Intelliflo, the suction line pvc can be glued into the fitting.
Make sure the pipe and inside of the fitting are clean. Glueing is a two step process. First apply a thin but even coat of purple primer on each surface to be joined: the outside of the pipe and the inside of suction fitting. After the primer dries, apply a thin even coat of glue to both surfaces. Immediately push the suction pipe all the way into the suction fitting.
Next we will connect the discharge side of the pool pump. Tape another 2" threaded fitting and screw it into the discharge port on top of the pump.
The next steps will involve connecting the power back to the new Pentair Intelliflo.
Note: The next steps will explain how the Intelliflo should be wired to a pool timer. Disregard the next steps and skip to step 33 if you do not have a pool pump timer.
The most common timer is the Intermatic T100 Series. For 220v models, the single speed pump is normally connected to terminals 2 and 4. You will need to move the lines from the pump from terminals 2 and 4 to terminals 1 and 3. The reason for this is that terminals 1 and 3 are always hot. This means there is always power running to whatever is hooked up to terminals 1 and 3. The display on the Intelliflo needs power to keep time and set programs.
The pump is now correctly wired so that the pump will always have electricity. Re-install the plastic insulator that covers the timer terminals.
If the pump has power there will be a green LED illuminated. At this point you will need to program the pump. This would include setting the minimum/maximum speed and run time. Since every application is different you will need to use the owner's manual in order to set the proper parameters for your pool.
