SOURCE: New Mastercool pads smell bad

The cellulose pads in a mastercool are glued together and usually the adhesive is what you smell. It may take a while for it to go away. Strange as it may seem, as the pads get more mineralization and you use it more the smell will go away. Do not use a cooler for your whole house without plenty of exhaust through a window or an updux. Coolers work best when there is plenty of freely moving air.

SOURCE: water pump size and over saturated pads

Louis, The cooling does not come from the volume of water running over the pads. It cools by cooling the air passing through the wet pads. So, Yours is an impeccably logical argument that leads to a false conclusion. Bigger is not better in this caThe fishy smell is from the matting (pads) when kept saturated, Molds and algae will form if there is too much water also.. Best you get the original size pump Good luck and stay cool - Ned

SOURCE: We have a Mastercool II & it was installed ~ 3

The pads you need are at least 8 inches thick. If you have the contractor model, then the pads will be 12 inches thick.
Find a distributor in your town that sells cooler parts, if they dont have them, some of the big home improvement stores carry the pads for your cooler.
Make sure you are using a bleedoff or a dump pump to eliminate the hard water out of the cooler. If you keep those pads clean, they wiil last for many years.

SOURCE: Mastercool pump runs when themostat is off.

Check the compressor relay (in the outside unit) Most likely it's stuck.

Just had my pad and pump replaced (12-inch pad) and now cooling is drastically reduced. The company said they installed a much higher capacity water pump usually used on large commercial units. Can too...

You may want to check to see if in fact the pads are wet. Sometimes the build up in the service tube along the top may be clogged not allowing the water to flow or perhaps the float is adjusted to low not allowing the pump to operate correctly. Once the pads are soaked it should cool nicely.

Squirrel cage installation.

If there is strong air flow blowing into the house the sq. cage should be OK. Possibly you need to replace the pads and make sure that the pump is not clogged and is distributing enough water to keep the pads wet.

AC pad not fully getting saturated with water

1. Make sure the pump is getting plenty of water.

2. Make sure the pump is working.

3. Check the pvc pipe with drip holes are not plug. (above the pads )

4. Check the pads directional arrow that should be facing up. When pads are initially installed you can see arrows on the pads. The arrows should be in the up direction. That will allow the pads to get saturated more efficiently.

I hope these steps help you.

Summer

If it was not drained for winter, do so and then remove all scale from the pan, pump inlet screen, etc. Replace the pads if they are scaled up and remove any scale from the louvered panels. WITH THE POWER OFF, check the belt for cracking and check to drive motor and blower wheel bearings for smooth operation, oil bearings with oil ports. With clean water in the sump, a good drive belt, clean pump screen and clean pads, the unit is ready to power up and run test the float action/shut-off, water distribution through the arms, belt tension (just enough to prevent slipping). These units work best when they can fully evaporate the water, so let the air flow out as fast as it come into the cooled space to maximize the evaporative effect. Also note, these unit must be level to work properly.
