How do I know wheather I need the T101M or the T104M?

A  Answered on 3/9/2008 by InyoPools Product Specialist Patrick P.

T101 or T104 should be on the inside door of your current timer or somewhere on the timer. If you cannot find this information you can unclip the timer clock mechanism and on the back of the timer there will be a motor. If there is a part # of WG1570 or 120V marked on the back of the timer motor then you would require a T101M 120V timer mechanism. If there is a part # of WG1573 or 240V marked on the back of the timer motor then you would require the T104M 240V timer mechanism.

I think mine is a 110 V not sure. How hard is timer to install. Don't have plug in rec. Have a flip switch, Will timer work on 110V?

A  Answered on 5/3/2015 by InyoPools Product Specialist Patrick P.

We have a guide here showing How To Install a Pool Timer Mechanism and it is not too difficult. This timer will not work on 110V you would require the T101M 110V Timer Mechanism.

Timer was losing two hours a day.

Written on 4/26/2020 by Guest

I assumed that one of the gears in my timer was slipping on its shaft with no way to repair so ordered this and all it took to replace the old one was to loosen 5 screws reroute the wires and was done. Took about five minutes and timer works just great.

Shipping was really faster than I expected. I have found a new source for pool supplies.

Pool Timer Did Not Work

Written on 4/5/2019 by Guest

First, shut off power to pool. Removed wires one by one from the old timer and put them on the new timer. Put timer back together and turned on. It works perfectly.
