press the up or down arrows to adjust the prime time from 0 minutes up to four minutes NexPress the display function button edit the speed setting for v1 you will notice the V1 LED is now blinking to indicate the pump is in the configuration menu the up and down arrows are used to adjust the speed between six hundred RPM’s and 3,000 rpm which are the minimum and maximum speeds for v1, v2 and v3 pressing the display function button again will display the speed setting for V2 use the Up and Down arrows to adjust when the display function button is pressed again you will see the timer setting for v2 to change press the up and down arrow buttons to adjust the time anywhere from thirty minutes up to 23 hours and 30 minutes next press the display function button to change the speed setting for v3 press the display function button again to change the timer setting for v3 when changes are complete Press that display function button to save settings now we can view our changes by pressing v1 v2 or v3 when we press v1 we first see the speed that is currently set pressing the display function button well display the current power consumption shown by the letter P when we have selected either v2 rev3 pressing the display function button once will display the remaining time left on that timer shown by the letter H pressing the display function button again will show the current power consumption for that speed when the run stop button is pressed at anytime during normal operation stop will be displayed on the screen the pump will come to a stop and will remain stopped until the run stop button is pressed again at which point the pump will resume normal operation to make a quick speed change to either v1 v2 or v3 while they are running press the up/down arrow buttons to increase or decrease the speed the LED for the change speed will begin to flash to save the speech change press both the up and down arrow buttons at the same time the LED should now be solid showing that speed has been changed after prime mode, the pump will automatically go to speed and time for v3 it will then change to v1 after the time set for v3 is complete v2 can only be engaged by pressing the V2 button the park does not automatically switch to v2 at any time here is an example of a possible installation for the max flow vs we can connect the pump to a switch time clock or filter control relay of a controller for daily start-up at v3 for speed and duration and then the pump automatically change to speed v1 at the end of the v3 timer as an example we could start up in v3 as a cleaner speed and then run v1 at a lower filtration speed this leaves v2 available for non-daily applications such as backwash we are now going to talk about basic troubleshooting when troubleshooting the pump it may be useful to run the pump without program functions being active this can be done in the service mode which only allows for motor RPM’s to be changed service mode is entered by removing power to the pump and then pressing and holding the display function button as power is turned back on test will then briefly be shown on the display and the LED’s for v1 through v3 will blink together to remind the user service mode is enabled the pump RPM’s can now be adjusted using the up and down arrow buttons to exit from service mode cycle the power to the pump off and back on if needed you can reset the pump to factory default settings remove power from the pump and then press and hold the run stop button while applying power back to the pump when the pump is turned back on the screen will display “reset” confirming that all settings have been reset to factory default settings the pump will then begin to operate in prime mode for professional help and service go to and select dealer locator which you will see if the top left of the website navigation bar next provide the zip code of where the pump is installed as well as 1.
