I have a Glacier Pool Cooler which doesn’t seem to be cooling the water. I noticed the fan at the top of the cooler is blowing the air up not down into the cooler basin. Is this the way the cooler works? I would think the fan should be blowing air down into the basin water to cool it and cause evaporation.

I know there are a few members with these installed. Let's see if this bump finds them!
so if you put your hand over the top of your cooler you feel the air being sucked down…. Not blowing up. I’m really confused. I see others from Houston (where I am) say the cooler lowers their temp by 5 to 8 degrees. My pool temp barely drops 2 degrees. Our pool is in full Sun pretty much sun up to sun down. The Cooler is also in the sun all day. Also I’m not sure if I have the water flowing in and out set right.
I have a Glacier chiller and it pulls air through the bottom screen and out of the top. I live in central SC and our humidity here is very high at night so I run mine during the day when the humidity is the lowest. My chiller will drop our pool temp 4-5 degrees which is perfect for us. It will keep the water temp in the mid 80s when air temp is in the mid 90s. our pool is in full sun all day. There are many posts on here discussing this especially in the Houston area.
One other thing. If you haven’t already done so, measure the temp on the pool return outlets. There should be a noticeable temp difference between the water coming out of the returns and the main pool water.

Checked my Glacier today and the fan definitely blows out through the top. Nearby in south Louisiana; it's noon right now, current air temp is 92, water temp is 89, and the chiller is outputting 84. That's only a 5 degree decrease, but is not surprising given the ongoing heat wave. Reminder that it's always best to run the chiller overnight to get maximum cooling. Earlier this morning mine peaked at 9 degrees before the sun got higher.
Also wanted to share the RPM table; you'll want to adjust the inlet valve to ensure the rotations are within the range for your model per this table for maximum efficiency:

Thanks everyone for the info. I just can’t understand why the temp in my pool is not dropping.
Ran it last night from 8 pm to 9:00 am pump speed 2400 and the temp did not drop even 1 degree. I’m stumped. I’ve read other threads from people who live in Houston and they seem to 4-5 degree temp drops regularly.

Did you happen to check how fast the wands are turning, and does the basin fill completely then drain completely when the sump pump starts? Believe this cycle should be about every 1.5 to 2 minutes or so, depending on your model.

Is the chiller plumbed correctly? The input to the chiller comes from the return side of the pump after the filter and the outlet of the chiller is connected to the suction side of the pump. At first glance, the plumbing seems counterintuitive but if you understand how the chiller works it makes sense. Many pool techs have no clue how the glacier units work and often don’t read the installation manual. It’s not uncommon for new glacier owners to post on here and the installation was done completely wrong.
Please post picture of the chiller and the equipment pad setup as well as the electrical setup.

Not sure I understand the above for wand rotation. Picture below of my model number.Checked my Glacier today and the fan definitely blows out through the top.

The pool builder had to replumb it 2x. We had to tell them how it needed to be plumbed. They didn’t have much experience with cooler installation and obviously did not read the manual. I believe it is now plumbed correctly.
Anyone in the Houston area know of a certified Glacier Pool Cooler installer. Would like to have an expert come check out the installation and operation of the cooler.

There are a series of spray heads on rotational wands inside the unit. They spray the warm pool water into a mist and the counter air flow upwards causes evaporative cooling of the water. If the wands rotates too fast then that means the internal pump pressure is too high and it will not efficiently cool.
I think you need to contact Glacier and describe the problem. Their technical support can probably walk you through a series of simple checks to determine if the unit is operating properly. I would not rely on pool techs to look at this, very few understand how these systems work and it will only waste your time.
Does any water leave the basin when the sumo pump is not pumping. I can’t seem to get the outlet set to fill up and drain in the 1-3 minutes it’s supposed to. It takes much longer than that for the basin to fill and pump to kick on and when pump does kick on it doesn’t always look like it drains far enough
I’m in Houston. Anyone know of any certified Glacier Cooler installers in Houston? My pool builder doesn’t have much experience with the Coolers. Would like to have an expert come take a look and verify it is plumbed correctly and I’m operating it correctly

@Treetopp based on your model number, the spray wands should make one full rotation 7-12 times per minute. You should have a sight glass on the side of the unit that you can pop off to time the rotations. You then open or close the inlet valve to adjust the speed. If water is splashing out of the basin, it’s too fast.
If your plumbing return line from the chiller basin is not directly to the pool and instead drains into the suction lines to the main pool pump, you may need to tweak that second ball valve a bit more open to make sure the sump pump drains the basin and pushes the water back into the filter system. Glacier recommends this valve at about 13% open.
As you have a salt water pool, it’s also a recommended maintenance activity to hose off inside the unit regularly to make sure salt deposits don’t clog the wands from being able to spray water down the membrane.

When you say spray wands do they actually spray. My wands have streams of water coming out when the fan is stopped. Does turning the fan on cause them to spray.
I really appreciate you taking the time to help me.
My wands look like they have streams of water coming out - not spray. Of course I’m seeing this with the fan off. Does turning the fan on cause the water to become a spray/mist?
