Thread: Mastercool problem

  1. #1

    Default Mastercool problem

    I just powered up my Mastercool Evap for the summer. The motor, pump, blower, are all in good condition and are properly set up.

    However, the air flow seems to be restricted. I removed the duct plate, so there should be flow.

    It works fine if I leave a panel off of the unit. When I put it on, the air gets restricted. This hasnt happened before.

    Am I forgetting something?

    thanks for the help

    Sounds like it's time to replace the pads.

    the pad does have a good ammount of deposits. I guess Ill try rinsing/scrubing it out, see if i can get one more season out of it, but ill probably just replace it.


    Thanks for the help!

    Default Pads

    It is often recommended to replace the pads each season. They come in individual sizes for a couple of bucks, or you can buy a roll of the material and cut it to size.

    Yeah I got 10 years out of my Mastercool pad, it was the 6 inch thick one, it weighed a ton because of all the calcium. And it wasn't cheap to replace, I wouldn't do it every year, maybe more like every 5 years.

    Default pad

    Verdeboy, you have never replaced a Mastercool pad if you think they just cost a couple of bucks.

    Default Pad

    I'm just talking about the generic stuff that looks like straw with a plastic outer lining. Or do you have to use the OEM pad with Mastercool?

    Verde,

    The Master Cool pads are a honey comb design out of paper, kinda like the craft paper they used for grocery shopping bags, mine is a one pad cooler, it's about 36" X 36" and 8" thick. I replaced it last year, I think it ran me around $120.00. Maybe I'll replumb it with the house soft water, that would take care of the calcium build up, that took care of the problems I was having with my back porch fogger.

    I've worked on dozens of units and they all took the cheap pads. My customers (most of them very poor) would never by a unit that required a $120 pad.
