![]() ![]() These should be adjusted as needed throughout the season. Second, you need to set the on and off trippers. Just to be clear, the time pointer should always point straight down to what would be the 6 o’clock position on a standard clock face. On occasion in the field, I have seen some pool owners make this mistake. If you do this, the trippers will not operate at the correct time as they rotate around the pointer. It may be tempting to take out a screwdriver and adjust the time pointer to the correct time on the time dial. ![]() Pro-tip: Most of these mechanical clocks are 24-hour clocks so you want to double-check that it is correctly set to AM or PM Rotate the dial until the silver time pointer is pointing to the correct time. This will disengage the dial from the gear on the back and you can now rotate the dial. To do this, pull the yellow-faced time dial (clockface) toward you. Check The Timer Motorįirst, you need to set the time, which is good to know in case of a power outage, or daylight savings adjustments. In general, the trippers will wear out with time, and occasionally the motor will burn itself out. As the time dial rotates around the time pointer the on and off trippers are attached to the time dial and “trip” the switch on and off as they pass the time pointer.Īs I said, it’s a very simple and eloquent system with very few moving parts. The only true replacement parts are the motor and the on/off trippers.Īs the motor receives voltage it then turns the time dial around the time pointer. Your basic components are the motor, the clockface(or time dial), the time pointer, the on and off trippers, and the manual override. Whether the timer in question is for 110v or 220v there is very little that can go wrong. The reason the Intermatic mechanical timer has lasted so long and continues to be used is the simplicity of its design. Also, for the purposes of this discussion, we are only talking about single-speed controls. In the context of swimming pool pump operation, and this article, when we talk about Intermatic timers we are talking about the 24-hour mechanical time clock and we often do so interchangeably. However, the yellow-face mechanical timers have become so commonplace over the years for pool pump controls that it has almost gone the way of Kleenex and Band-Aid where the brand name has replaced the description of the product. And of course, they have applications beyond swimming pools as well. Their controllers can operate 2-speed pumps, variable speed pumps, multiple pump systems, as well as accessories and remote controls. The Intermatic brand actually has a whole line of mechanical and digital controllers for all sorts of applications beyond single-speed pool pumps. Intermatic Pool Pump Timerįor many years the Intermatic brand electro-mechanical 24-hour timer clock has been the most available option to control swimming pool single-speed pump operation. Third, set the on and off trippers for the correct run times. ![]() Second, set the clock to the current time. First, check the inspection window to make sure the clock is getting power and is operating. Mechanical clock pool timers have very few functions that you have to worry about. It’s a pretty simple process, let me explain how it’s done. I’m occasionally still surprised when I get a call from someone who doesn’t know how to set the pool timer or adjust the clock. Rather than try to remember to turn a pool pump on and off every day, pool builders and owners have traditionally decided to install timers on their pool pumps to establish some form of autonomy for their pool filtration.
