If not, then the problem is due to excessive load. If the voltage differ substantially, they you might have the wrong kind of wire. Use protective wear like isolating gloves and boots, so you won't sue me in case of accident. Also, measure the voltage at the other end of the wire (away from the motor). When calculating the wire gauge, you have to take into accout the length that you use.įirst thing, measure the voltage at the motor terminals with the motor running. Using heavier gauge might not be enought, if you are looking for the amps. If the sum of the windings has a resistance of, say, 6 Ohm, the wire should have a resistance smaller than 0.6 Ohm. Also, tell me the flow you have in the pump (litres per second).Īlso, as sugested before, this could be due to having the motor running below the nominal voltage, and this situation might overheat the motor as the motor at lower voltages will have much less speed, thus drawing more current (has the same effects of applying too much load). Believe me, I'm graduating as a chemical engineer and have some experience. You should check for the outflow load and for incrustations in the pipes. One question, what kind of motor it is? Is it from a centrifugal pump? Or form a piston pump? (should be centrifugal). If you read the 18.6A from the plate (seems to be a nominal value to me), then your motor is probably with too much load, that is, you are demanding too much from the motor in terms of load. In a series circuit, the current is equal at any point.Īn 1.5hp motor should have 1125W of output or shaft power, but depending on motor efficiency, it will consume more than that (more than 9.375Amps). Set the pool timer to "Automatic," and it will turn your pool pump on for the time interval you selected, and off when the timed run has been completed.Click to expand.This doesn't has to do with distance. You don’t have to spend a lot of time using smart board Easy to Use: 12/24 hours can be switched according to your needs The timer is anti-interference and easy to use. Step 12: Turn the Pool Timer Switch to Automatic Clear: Electric timer uses a high-definition display design, you can view it at a glance, and smart timer for pool pump is very convenient to use. To save money run the pool pump on the timer during off-peak hours, such as before 6 a.m. The pool timer should always run the pool pump while people are swimming in the pool, for maximum aeration and cleaning of the water. Be sure to program the timer for at least 5 hours of continuous operation. Step 11: Program the Timerįollow the directions in the pool timer user manual to program the timer. Set the pool timer to manual control, and ensure it turns on the pool pump according to the directions on the user manual for the timer. Step 10: Activate the Manual Control of the Pool Timer Use a voltmeter to test that the correct voltage is running through the pool timer. T urn the circuit breaker switch to the "On" position. Step 8: Restore Electricity to the Pool Timer Circuit Step 7: Close and Seal the Timer Boxįlip down the plastic lid cover of the timer box and secure it with the small screws supplied. Make sure they are covered completely to prevent corrosion and exposure to the pool water. Step 6: Wrap All Wire Ends in Electrical TapeĬover all exposed wire ends with 2 rounds of duct tape. Wrap the loose end of the white wire around the terminal 1 screw. Step 5: Attach the White Wire to Terminal 1 ![]() Wrap the green ground wires around the ground terminal screw labeled inside the timer box. The last length of black wire will continue from the timer to the pump, labeled as "Load." Step 4: Ground the Pool Pump Timer The white wire will be labeled "Load," and the black wire will be labeled "Hot." Step 3: Wire the Terminals of the Pool Pump Timer and the PumpĬut a short piece of wire, 6 inches long to wrap around the second and third terminal screws inside the timer. Step 2: Attach the Pool Pump Timer to the Electrical SourceĪttach the black and white wires to the electrical source. Step 1: Turn Off the Circuit Breaker / Fuse to the Electricity Sourceįlip the circuit breaker switch to the "Off" position, or detach the fuse from the fuse box as needed to disconnect electricity to the power source for the pool timer. Learn how to install a pool timer following the directions below. Regular pool pumping for between 5 and 8 hours a day keeps your pool healthy and ready for swimmers throughout the summer months. Using a pool timer on your pool pump for a fixed amount of time daily can save you energy and money.
