Help changing filter for CMC431 mastercool evap cooler

Have removed inlet panel, but instructions then say "remove wet section top" which is not pointed on in the exploded view of the system. the filter is very rigid and not sure if it was compressed to get put into place, but calcium and lime build up is making it too rigid now.

SOURCE: 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.

Jerry,

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: 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.

I am a single woman trying to prepare my mastercool for winter. I don't know how to remove the pads, so if insructions could be sent, it would be greatly appreciated. I don't know the size of the cooler,...


Is it a side draft or downdraft cooler? My instructions simply say to cover the unit, disconnect the power and drain the water for winter. They don't suggest removing or cleaning the pads until spring. If you're ductwork also is connected to your furnace, and you don't have a cookie sheet(piece of sheet metal that fits in a slot beneath mastercool unit or along the inside if it's a side draft cooler) then besides covering the entire unit you cn probably cover the blower, also called the squirrel cage, with a canvas cover.

Does it need to be cleaned, if so. how is that done? AdobeAir /Mastercool model P700 serial number B150809633


Yes, it needs to be cleaned. Go to your local home store and (in the evap cooler section) pick up a bottle of evap cleaner/scale remover. Just follow the directions on the bottle. It will last MUCH longer with proper care and cleaning.

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.
