You would be able to but that is no longer available.

My GPC25 was delivered today ON A PALLOT. It is due to be installed on Thursday. You mention that an installation and parts needed list is in the bottom of the BOX. Will I find this information in the actual unit----which is shrink wrapped and on a pallot?

A     Answered on 7/1/2015 by Lennox H.

Hi Larry, The instructions and manual is located in the box.

I have 12,500 gallon salt water pool in orlando Fl. pool temp is already up to 95 degrees during the day. I have solar that i run at night that gts it down to 87 but it quickly get back over 90 when the sun comes up. ot even sure the solar is doing much as the i think the pool temp would drop to that on its own at night. I have a semi dark pebble finish. Which unit would you reccomend?

A     Answered on 6/18/2015 by Dennis R.

HI Matt,  The manufacturer recommends going to the next larger size if you have a pebble finish and your pool size is close to the upper limit. At 12,500 gallons you should be fine with the GPC25 unit.

When the weather gets a little cooler I can by pass the chiller, right.

A     Answered on 6/15/2015 by Patrick P.

Yes we would suggest a diverter valve which would allow you to by pass the chiller.

How cold with this unit make my pool? Will it get it down to 50 degrees?

A     Answered on 9/17/2014 by Patrick P.

Glacier has advised me that their pool coolers will not drop water temperature down to 50°. You can get a 12° to 15° degree drop from hot water temps of 90° to 98°.

What is the pad footprint required for the GPC25? I see is shows width of 34", but wasn't sure if it required additional spacing, as I'm wanting to install in between 2 A/C units.

A     Answered on 6/30/2010 by Patrick P.

34" is the basin diameter, this unit fits on a 2X2 pad. You need to have at least 2 inches on each side for clearance.

Can this cooling system be used with a salt water pool?

A     Answered on 7/12/2009 by Patrick P.

All of the chillers we carry are salt water compatible. After a couple of weeks of usage, spray down the pool cooler with a garden hose to wash off salt residue if any.

?     Asked on 7/4/2009 by Guest

Our summer temperatures average 98-103. Our pool is extremely warm. How much of a drop in water temperature can we expect? Does the unit have to run continually to be effective and finally, what type of operating costs can be attributed to this unit?

A     Answered on 7/4/2009 by Patrick P.

The pool cooler will drop the pool 10 to 15 degrees. The operating costs are around a dollar a night on running the cooler 10 hours. It does not have to run continually, just run it at night when the sun is off the pool and it will perform and drop this pool down and be refreshing.

?     Asked on 8/12/2008 by Guest

Is this an evaporative cooler - or does it just cool water by running at night with lower temperatures? How does it work?

A     Answered on 8/12/2008 by Patrick P.

Yes, this system is based on evaporative cooling.  The manufacture has modified the technology to accommodate the swimming pool industry.  The pool water is circulated through the system while a fan cools the droplets and removes the heat from the water instantly.  The water is then pumped back into the pool lines and circulated back into the pool.

?     Asked on 7/16/2008 by Guest

What size breaker does this unit require and what is the running amp draw?

A     Answered on 7/16/2008 by Patrick P.

The cooler piggy backs off the pool pumps power, so the combined amperage will require a 20 amp breaker.  The cooler maxes at around 8 amps (when it is initially turned on) and averages 4 amps while it is running.

?     Asked on 7/16/2008 by Guest

Does the Glacier pool cooler have a thermostat? If not how do you regulate temperature?

A     Answered on 7/16/2008 by Patrick P.

The GPC does not come with a temperature control.  In most cases an owner will run their cooler at night along with their pool's cycle.  An owner may find that running the pool a longer or shorter amount of time will give them their optimal temperature.

?     Asked on 7/5/2008 by Guest

Can I install my self? What is the refrigerant? Must it be replenished?

A     Answered on 7/5/2008 by Patrick P.

Yes, anyone can install the pool cooler themselves. In the bottom basis in the box is the installation ,operation manual with diagram and parts list. You can go to a local hardware store and get the proper installation parts. There is no refrigeration, no freon or gas to operate. Electric 110 Volt 60 Hertz 8 Amps fan does the work. This unit hooks up with the pool pump breaker. The home breaker powering the pool pump and pool cooler must be 20 Amps or above.

from Houston, TX ()

Hello, I just purchased a pool chiller from your company. Prior to the chiller my pool has been unusable. It's temperature was 95 degrees before installation of the chiller. Now it is a refreshing 83 degrees. I cannot recommend your company enough. It is very rare that a product lives up to it's rputation, but yours certainly does. Thank you again.

 (5 out of 5 stars)  Does the job

from Wilmington, N.C. ()

Pros: Price, low operating costs.

Cons: Installation was not simple

In Wilmington N.C. we have a 17,0000 gal. pool with PebbleTech. In mid-June the water was 90 degrees by 4 p.m. Now, with the Glacier Chiller, in late July the water stays between 80 and 82. Installation was about $900 because the chiller was integrated with Pentair remote system. Would recommend the Glacier Chiller to anyone looking for a relatively economical answer to tepid pool water. The Glacier Chiller is great!!!

 (5 out of 5 stars)  Great Pool Cooler

from High Point, North Carolina! ()

The pool cooler exceeded my expectations! I live in North Carolina and have a beautiful dark bottom pool in full sun. When we have 90 degree weather the pool water would hit 90 degrees during July & August and not be usable. I have had the pool cooler for a month now and when we have had back to back 90 degree days the water stays at 78 degrees when I run it 12 hours a day. This is the best purchase I have made in years! Love it!

 (5 out of 5 stars)  Pool Chiller

from Little rock, Arkansas ()

Pros: Cools water, easy install, quality product, good customer service reps if you have questions

Cons: Have to switch off/on bc not on timer

Wonderful. Amazing product. This does for your pool what your ice chest does for beer. Our pool is in direct sun all day and the water temp would be in the mid to high 90's. The pool chiller will keep the pool temp in the mid 80's if you let it run more than 6 hrs a day. We try to keep our pool around 89 so the chiller runs about 4 hrs per day during the hot summer months. Building a new home and pool and buying our third chiller. Excellent product. Easy to maintain. Takes 5 minutes to drain if you winterize. Very easy to install. My husband has installed all of them. Very basic and easy to follow instructions.

 (5 out of 5 stars)  Works Quickly as Advertised. Solidly built.

from West Palm Beach,, FL ()

Pros: Works as advertised. Low initial cost and operating cost when compared to heat pumps with cooling cycles. Solid construction. Clear installation instructions

Cons: Some spatter and additional water loss due to cooling method and evaporation, not significant enough to be bothersome.

After my second summer in south Florida and with an inground pool hovering in the mid 90's from early July I broke down and ordered this unit. I've done the Pvc fountains in the outlets etc. but the cooling just never got it cold enough to carry through the day. I ordered the unit and some valves and actuators that would allow me to tie it in with my existing Aqualink system from a control perspective in order to maintain sanity when the spa and gas heater is used vs just the pool circulation and cooling. Ididthe install myself and the whole exercise took me around five days which included pouring an additional slab next to the existing one to accomodate the expanded footprint. The pool temperature on a 14k gallon salt water pool dropped the first night running from 8pm to 6 am from 94.9 down to 86.9. The second night it dropped further to 83.5. I ended up swithcing the unit off for the last two nights - the kids complained the pool was getting too cold. Our daytime temperatures have been hovering in the low to mid 90's with humidity around 90%+. overnight temps have been in the upper 70's to low 80's. I am extremely pleased with this purchase.

 (5 out of 5 stars)  It works!

from Houston, TX ()

Pros: It works!

In the summer my pool gets to 92+ degrees. Basically, from the middle of June to October, the pool was unusable. I did a lot of research and decided on the Inyo cooler. In one night it drops the temp five degrees and a few more the following night. I run it a few nights before the weekend and the pool is refreshing when it hits 100 during the day. I was a little skepical when I bought it but now can fully recommend this unit. CALL THEM AND GET A RECOMMENDATION AS TO PLUMBERS IN YOUR AREA FOR INSTALLATION!!!

 (5 out of 5 stars)  Awesome cooler

from Warsaw, Indiana ()

We live in northern Indiana and our pool water usually doesn't go over 90 degrees until late August...not this year; we had water that was 94 degrees mid-June! Purchasing this pool cooler was the best investment. We no longer have an 11,000 gallon bathtub! Even with the air temperature in the 70's at night, the water is cooled to 82. REFRESHING! Installation was a breeze as well.

 (5 out of 5 stars)  It simply works, period

from Oklahoma City, OK ()

Pros: easily integrated into my pool systems

We had a record hot 2011 summer here in Oklahoma. When I needed my pool most, the water was 95 degrees. Ugh! I bought and installed the Glacier. It simply worked exactly as advertised. Cooled the pool down to 85 degrees in one night. We took it down to a perfect 82 the next. We were easily able to keep our pool exactly where we wanted the rest of the summer, no matter how hot the days and nights. We enjoyed our pool through the final 30 days of 100+ degree heat. If you live in an area where you have hot days and nights and your pool gets too warm when you need it most, you need this device.
