JANDY LOW pressure ref problem

Thu, 03 May 2012 17:23:44 GMT

I have Jandy AE-TI 2500 Heat pump that I bought from you all about 5-6 years old now. I just turned it on for the start of the season a couple days ago. Ran for couple hours and was producing warm water. Then it shutdown, ie. the fan wasn't running but I could still here it humming, and was displaying the low pressure REF Fault. Sound like compressor was on but fan wasn't spinning.

I recycled power a few times. Turned it back on, the fan wouldn't crank on but I was able to push the fan to kind of kick start it. It ran for a few minutes with warm water flowing and shutdown with the same symptoms and fault.

I notice that the coils were beginning to freeze/frost over as well. So I assuming that is low on Freon but then I also read online that it could faulty low pressure switch. I’m just trying to determine which to look at or try first. Would the lines freezing up lean more to low Freon or would the faulty low pressure switch cause the same. But I also questing whether or not it the fan motor.

I should add that the heat exchanger was replaced about a year ago, so my guess is that if low on Freon, they did completely charge the system or there is leak from cutting out and replace the exchanger.

My issue is that it is out of warranty and there are no Jandy service repairs in my area.

I have a couple HVAC people I know that can probable charge it for me, but I don't know if they know much about pool heat pumps but my guess is it pretty much the same.

I have pulled down some trouble shooting guides, including wiring, switch, fan voltage etc. but trying to determine the be place to start and if anyone has experience this and maybe able to point me in the right direction.

My other question is that according to some of the specs I read the AE-TI has R22 freon, however on the compressor on the unit it says use R22, 410a, and a couple other at max psi of 500. Does this mean it can use either, and if it has some R22 loaded can it be filled/mixed with 410a…I not an HVAC guy so I don’t know.

New heat pump

Fri, 30 Mar 2012 20:46:18 GMT

I had a new 130,000 btu Rome Heat and Cool heat pump installed in Phoenix earlier this year. I have had limited time to run it to find out if it is working properly but I have a couple of questions.

It seems that you have to have your water pump running all the time in order for your heat pump to work. Doesn't this defeat the purpose of the pump being energy efficient. Perhpas there is some way for the heat pump to turn on the water pump when it senses that more heat is required to the pool? if there is I am not aware of it.

Secondly when I did run the heat pump it did stop working and the display indicated that it may have been a problem with icing. I was of the understanding that the pump because it is a heat and cool model it would automatically defrost and keep on working. Is this not the case? For your info the ambient temp was about 50 degrees.

Any help would be appreciated.

Heat Pump Problem

Tue, 20 Dec 2011 17:52:32 GMT

Dear Marcus, an old Air Energy heat pump that came with the home we just purchased so I do not know any maintenance history. The fan operates but it does not sound like the compresser turns on. The pool did not get any warmer after 4 days of running the pump. I had a technician look at the pump and he said he was not familar with the old Air Energy pumps but he did state he thought the compresser is bad. Last thing is every 4-5 minutes while the pump operates I hear a short squeal from inside the pump. Do you have any suggustions for me?? Thanks Jeff

Temperature setting

Tue, 22 Nov 2011 00:13:52 GMT

I have a Rome s-95 electric heat pump. The display stays at 95 degrees all the time. I set the temp to say 80 degrees and then it goes to 95 and starts. Everything else seems to work fine. It would probably run until the pool water got to 95 if I let it. Is there a way to calibrate the thermostate?

New Heatpump Installation selection

Thu, 29 Sep 2011 07:13:54 GMT

I noticed a few others have a Macon heat pump from China and are having some issues. I am also in the Comox valley and the contractor is promoting this pump 045ZB (84,700 BTU) for a new installation of a 14 x 32 shallow draft San Juan pool with cover.. As our Spring and Fall temperatures are in the low 60s during the day I am concerned that the unit will freeze up in-spite of its short cycle defrost claims. What other units have reversing functions that have proved reliable. I do not know how much the contractor is saving on this unit but do not want reliability or warranty issues down the road that would impact up time for the pool.

Breakers keeps tripping hayward pump

Sun, 14 Aug 2011 19:16:26 GMT

Hi to everyone here, this is my first post

breaker keeps tripping every time I turn it on!!!

We had a 50,000 Hayward heat pump installed to my pool. We ran 10/3 wire with ground to the heat pump. it requires a dual pole 20 amp 240 breaker. It only needed two hot wires and a ground with no neutral! we hooked the wires up to the pump just like the manual says with no neutral but it trips the breaker every time we turn it on.

can it be wired wrong with only two hot wires?

Can anyone tell me what is wrong?

Thanks

Dedicated circuit for heat pump.

Sun, 14 Aug 2011 01:47:23 GMT

Good day. When I installed my pool three years ago I only ran a three wire 120V circuit, about 60 feet of which is buried. The wife now wants the pool heated so I think a heat pump is the best way to go. I am planning on getting about a 50000 btu unit ( 18 foot above ground with solar blanket). My pump and clorinator are 120v, no 220 option. To avoid running a new cable I was planning on changing the circuit to 220 and getting a 3000W step down transformer ( about 100$) for the pump and clorinator put it in a enclosure and run the heat pump, clorinator and pump off one 220 outlet.

Any issue with this or should I just bite the bullet and run a second dedicated 220 feed ? Another option would be a spa panel with two breakers but I would still need the transformer since I don't have a 4 wire circuit.

Acceptable Temp Difference

Fri, 12 Aug 2011 02:21:43 GMT

Hi All,

Just wondering what an acceptable temperature difference is from ambient pool water temp to what the heater is putting out of the return. Want to know if my heater is working up to snuff.

Thanks,
Jason

btw great forum!

Defective Compressor Heatsiphon DXG5.0hpx 3phase 50hz 380/460V Scroll Digital

Sun, 31 Jul 2011 16:36:04 GMT

Hello,

may be someone could help, otherwise I will give all the hint "don´t buy a heatpump from heatsiphon".

I ´ve bought the heat pump in October 2008 directly from heatsiphon, this year in April 2011 the compressor was defective, after contacting Miss Gianini (the tech-support from heatsiphon) via chat - here is an extract:

"OK, Part is in warranty, you will have to pay for freight to get it to you and labor to have it installed. I will email you shortly with freight quote and lead time to get the compressor in from our supplier.

Dr. Khalil:
on your homepage you write: Strongest Warranty in the Industry
In addition to our UNCONDITIONAL LIFETIME HEAT EXCHANGER CORROSION WARRANTY, HEAT SIPHON has the STRONGEST WARRANTY in the pool heating industry WHERE IT COUNTS

A FULL FIVE YEARS PARTS AND LABOR COMPRESSOR WARRANTY. Your compressor is the MOST EXPENSIVE PART TO REPLACE - at least THREE TIMES the cost of the next most expensive service part.

NO FINE PRINT - NOT PRO-RATED like our competition. At 4 years and 11 months you still get a new compressor and we pay for the labor to put it in, and we back it up with quick, hassle-free warranty service from our network of Factory Authorized Service Centers.
Dr. Khalil:
so why i have to pay for the labour?
Sue:
That is USA Warranty where service centers are set up with contracted rates. I will email you shortly
Dr. Khalil:
ok thank you sue"

That´s the last email on 12th April 2011:

LEAD Time to get compressor is 3 weeks.

Freight will be $258.95 Air 3-5 days.

Get a quote for labor and email it. Maybe we can give you the freight free to cover labor cost. Warmest Reqards, Sue Giannini

I contacted again and again, the CEO Mr.Bernardi as well and also by my solicitor

Up to now: I´ve got no compressor, no answer, nothing. May be the reason could be, that I´m living in Germany.

Best wishes Khalil

Question re used heat pump

Mon, 25 Jul 2011 23:39:18 GMT

I am considering buying a 1.5 year old used Focus Temp Insta pool pump for my 24 foot above-ground pool. The seller indicates he paid $1200 for it new. (I found an ad for one at $1196-although it was out of stock). I am concerned because the price for this pump is significantly less than any other heat pumps I have found. Do you know anything about this particular model and any reason why it is priced so low? Any input will be greatly appreciated.

Panama City Beach Heat Pump?

Thu, 21 Jul 2011 03:51:29 GMT

We are purchasing a home next month and I am looking into a heater for the pool. I thought gas was best until I started reading about heat pumps. Are they good for this area? It is an in-ground pool. Fairly large but I do not know the size at this time. Screened in, partial shade.

Wiring Question Run 8/2 or 8/3

Mon, 04 Jul 2011 18:46:42 GMT

Greetings

Great discussion boards here!

Quick question:

I will be installing heat pump (either a Hayward 85k or Waterco 85k) and am wondering if its common to have 1 hot or 2 hot wires plus neutral and ground to these devices. I have thoroughly looked over the online specs and wiring diagram which indicates two wires in (black and white, likely american diagram). Just need to know since I will be burying the line myself in conduit and need to know what to purchase.

Single phase 220v, operating amps 27.8

thanks kindly for any input

Heat Pump Icing Up

Mon, 30 May 2011 15:54:55 GMT

I have a MACON MALCRW045ZB Swimming Pool Heat Pump.

I live on Vancouver Island, Comox Valley. My heat pump is icing up even at temperatures around 13c. It does go through a de-icing mode, the ice melts but builds up again soon after when it resumes water heating. Is this normal?

The pressure guage indicates a pressure reading of 200psi and goes up to just above 300psi after it has run for a while. Is this normal? Sticker on front says normal operating pressures should be 300min to 600max.

I'm wondering if this is 2 problems or they could be linked - or maybe no problem at all.

Thanks, Ken

install and use of solarium 85k

Sun, 22 May 2011 21:45:54 GMT

Hi! We just bought a solarium 85kbtu heater for our above ground pool. Does it only work when the filter is on? We set the filter timer for 8hrs per night. How does the heater work when the filter is off? Also, do you know any installers in the Prt Jefferson, NY area?
