Pentair pump wiring Line 1 Line 2?

On a 230v motor install my wiring diagram shows Line 1 as the top post and Line 2 as the bottom post. What color wires are typically associated with which or is there a way to tell what wire should be my line 1 vs line 2? This is a pentair whisperflo.

basically either or as long as you follow the diagram on the side of motor it does not matter when hooking it up to the timer.

I have seen black-black, white-black, red-black & all have been different.

On a 230 line typically you will have two current carrying wires and a ground. The "hot" wires are normally black or red. Like MrClean said, doesn't matter which hot wire goes to line 1 or line 2. The ground wire should be green and connect to the ground screw.

Ok I was confused because I didn't look at my clock diagram first. There it clearly labels the L1 and L2 posts. Thanks!

I replaced my pentair booster pump over the weekend. The shaft is turning counterclockwise, when facing the pump intake. According to pentair this is backward, what did I do wrong?

I think I have the same 2HP pump and was wondering where the neutral wire is supposed to go?

After thinking about it some more, can someone please confirm that I'm supposed to use 14-2 wire enclosed in metal conduit, run both the black and white wires to my HOT leads from the timer relay and then the bare ground goes to green. Then there really is no neutral in this diagram?

According to the electrical requirements diagram, I can use 14 AWG for 230V on 2HP less than 50'.

Hi,

What voltage is your time clock? Normally you would have 2 hot wires coming to the clock (black or red) and then you run 2 hot wires and ground to the pump motor.

I like to use sealtite flex conduit to run from the clock to the pump motor.

Thanks for your feedback Denali.

I'm using a "Fiberstars WPC-2" Wireless Pool Control Unit with a timer that can be wired for either 110V or 220V with a max load of 3HP@8AMP continuous load.

I'm extremely disappointed with the so called "Technical Support" for Pentair. They refused to discuss anything about the wiring to the pump and wouldn't even confirm that there is no neutral wire to be installed on the pump.

I'll definitely buy the pvc flex line since that sounds like it's a lot easier to work with and use some 14-2 romex that I have left over from wiring my shed.

Thanks Again!

Okay now I seem to have confused myself some more. I was originally thinking that I've got a single speed pump, but after looking at the wiring diagram on the side of the housing, it's making me think that it's a dual speed pump:

I say this only because it lists a LOW VOLTAGE and a HIGH VOLTAGE, but if it's a dual speed pump, then the wiring diagram for the WPC-2 shows 4 inputs to the pump and there is only room for 3 inputs.... :crazy:

The low and high voltage are just the diagrams for 110v and 220v. Normally they come wired for 220v so if that is what you are using from the time clock no need to change the wiring inside the motor.

I went ahead and wired it as a single speed pump and all seems to working fine, minus a few leaks on the slip joints that had to be repaired. There's also a minor leak on the check valve through the clear glass sight. I've tightened the screws down as hard as I can manually, however the leak is still there. Does anyone know of a special gasket that might be missing or should I use my impact drill to tighten them down a little more?

Hi,

Id like to confirm a US pool pump wiring concept. The average US pool pump has;

Three wires -
Active 1 (HOT/RED) - Phase 1 110V (0 Degrees)
Active 2 (HOT/RED) - Phase 2 110 V (180 dgrees)
Ground.

How this works is, by using two phases out of sync, both hot wires become a potential of around 230VAC, but alternating between active and neutral on each of the hot wires (thus their equal ambiguous red active colour).

Ground is ground.

Does this sound correct?

I will be cabling a new very sexy pentair VF pool pump here in Australia, and I need to confirm how this should be done. We have a clean single phase high current 240VAC Active, Neutral and Earth set up. Earth is used primarily as a reference to detect leakage (to shut of active during faults). Neutral is bonded to earth at the fuse box and is used as a current return for active. Active is a fat 240VAC/16A single phase hot supply. Although the US pump will receive a 230V supply, its active and neutral polarity will not be changing with phase - its this bit I need to confirm is ok.

Anyone experts have any suggestions or idea's?

Thanks,
Steve

Here it is - works a treat!

I have a new pump w/ 115/230. My wiring used to be for a 2 speed pump. I have 2 black wires, 1 red wire and 1 green wire. Do I just hook up the 2 power wires and the green ground wire or do I need to hook up the red wire as well? I guessing that the red wire may have been used for the 2 speed option on the last pump.
