what is v2 used for if pump doesnt go automatically to it ..i see you can set the rpm and the timer but the pump doesnt cycle to it.

I guess that you have to turn on v2 manually, my pump run for 2 hour in v2 and then go to low rpm.I wish that it was more quiet on high speed, it is real noisy.
1850567
I wondered the same thing. Why set the rpm's and time in hours if it won't cycle?

You can manually put motor into v2 instead of v3. That is another weakness of this set up, but one wich does not affect me that's why I didn't mention it in my review.

It depends on the wiring for the pump. If the wiring is correct, there shouldn't be any issues. ... I can set this timer for different times each day. And there is a manual override

I believe it would be fairly simple to wire in a momentary contact (push-button) switch to allow you to manually trigger the pump. This should wire in to the same two terminals that the float switch connects to, and would momentarily bypass the float switch circuit, applying power to the switch motor.

Carl G I would like to know why you needed an oil lubricated pump? Changing to wet rotor may be an issue because of the clearances...if it stops it might only a small particle...I once had some system "goo" hat stopped one...it took washing it out with diesel to get it back running. Both engineering submitals indicate the NRF22 is about 2GPM less than the LR20BF at 10ft head...so here's the thing...depending on what system youre installing it on...most systems were designed for 160f DHW or 180f HWH water so by putting this in (I dont know your system but I would do it) you'll have a slighting lower flow rate...in DHW who cares as its no big deal...BUT in a HWH system your control valves will open more and this is a seriously good thing in modulating valves. There will be a larger delta T so I'd also lower my boiler temperature by at least 20f assuming youve some form of condensing boiler...this will help ensure youre in condensing mode. Circulate fluid...not temperature and you'll save a lot of money. Make sure your side stream filter is clean and check it a few times in the first 1-2 months because the more flow means the more crud is likely to get back to your HEX...if there isnt one put a Y strainer in and add a "sock" on the screen for a month or 2). A possible problem is how many zones open/ resistance decreases across too many different circuits/ zones...too many and there wont be enough. The system I installed this on it is actually the primary circulator through a 2xwall HEX serving the HWH off the DHW system...it works so well Ive been promoting it/ its been installed on 3 systems in this last year (its not my J.O.B but I do design energy and conservation projects as is my profession). Last, make sure the expansion tank is on the pump inlet side/ the return (DHWR or HWHR)...these high speed pumps cannot handle even a minimal bit of cavitation. All the best

Yes make sure pump timer is set to proper am or pm and running. Second that valve is installed properly under the sink. If this does not work do an exchange for a new valve.This is my second unit i have installed myself and instructions are very clear never had any problems.

You will need to plug it in to a timer if you want it on a schedule. Without a timer, this regulator is either on or off. You can adjust the flow rate, but that is all.

The pump is automatic, onceIt fills up, it automatically pumps it out. Or u can do it manually..

Hi Paul H,Is there any update ? Have you talked to your technician ? It's almost a week and that pump is still not doing anything, I really want it to work.Thank you.

So they just contract and stay contracted? Has the pump worked for you before or is this the first time you're using it? First, I'd make sure all the parts are connected properly (push firmly at each connection), especially the white valves underneath the flanges. If that doesn't help, inspect each part of the kit (valves, diaphragm, tubing) for any tears or holes. Do you have any spare parts you can swap out to see if it's one of your parts? If none of the above work, try using the manual pump with the kit for now and call Customer Service. It may be your motor. :( I had problems with suction a few times but it was always the result of forgetting to properly assemble some part, probably because of sleep deprivation. Hopefully it starts working for you soon!

I believe it says 2 he's less than your pump. Well that's why I do anyway. After you set the timer, it will come on shortly after your pump comes on, then cut off after the set number of hours.

I think you are better having it closer to the basin (above the pump of course) because when the pump cycles off, then there is less water between the pump and the valve. This water, after the pump cycles off, then evacuates via the small hole you are supposed to drill in the outlet pipe where it connects to the pump. This eliminates (water) pressure back into the pump when the pump starts the next time.

Do you want the automatic pump to run when the battery power is turned off? If so any single pole switch will work because your power to the float is wired direct to the battery. While the other power wire runs to the switch from battery controlling the manual operation. Did this help?

For the price I purchased two late last year. Not sure if it would be worth trying to get it fixed. The problem I had with the other one was an automatic shut off which constantly shut the pump off even when the tank I was filling was not full.

Yes... wire up the power to your timer, then wire off of your timer a standard plug. You can plug your pump into this plug and your timer will turn this plug off and on.

The manual is very minimal, but it is a very simple pump. I do not remember a labeled diagram of parts since the pump is small and inexpensive I would not try to repair the pump. I would simply replace it when it fails. The same goes for the maintenance. Just keep the pump inlet clean so the inlet does not clog or so that any debris gets into the pump. There is no routine maintenance needed on a pump this small that runs only a few times an hour.

This system is simple, no timer or timing needed. This is a simple pumping column that works with an aquarium air pump (you'll need to get the air pump separately if you don't already have one. If you need it on a timer, plug your air pump into a timer. You can pick up cheap timers here at Amazon, or Walmart, Home Depot, etc. I personally use them in hydro grows with no timers.

I own a variable speed pump, the circulator barely works at low speeds. The 1st one I purchased didn't work, the 2nd one worked for about 5 months and it has stopped. I contacted the company months ago and NO RESPONSE! Don't purchase it.
