Wiring issue on mastercool 5 CFM 2 stage pump

I have a Mastercool 5CFM 2 Stage pump in which the cord was pulled out of it. It was still holding on slighty but decided to just replace the cord anyway. In removing the cord I have forgot where the wires go. I see different terminals(with numbers next to them) in the back but dont know which wires plug to where. The Model # is C55JXJFY-4450. I would really appreciate the help or where I could look to solve this issue. Thanks

    you are a chump Jim. that isn't even what he asked and you answeer with basic information that is completely unhelpful. I have the same problem with my pump and I am VERY aware of black being hot, white being neutral and green being ground. On the pump "circuit" board there are several places you can put the "hot" lead and that was the question asked. Next time dont be a ********* and waste everyones time by just keeping your fingers off the keyboard. As for the problem the original person had, I am not sure where they go, and am having a similar problem

I have a MasterCool II MC63/64B and the thermostat has gone out. Since MasterCool is out of business, what model/brand would I replace it with.


If you are just running the evaporative cooler any single stage thermostat will suffice. You can buy them at OSH, Home Depot or Lowe's and probably Ace Hardware.

Question is whether to get an Kobalt 80 gallon 14 CFM at 90 one stage or a 60 gallon IR 18CFM at 90 if the price is the same and CFM is not the issue, but the quality of the item?


your choice of an air compressor should be based on what you are going to be using it for first of all .single stage compressors are good for about 125 psi 2 stage up to 175.which whatever one you choose do not get a oilless they wont last .you want a cast iron pump which requires oil lubrication.pumps which are made of aluminum are throw a ways

How do i operate it?


Go to the Mastercool web site:
http://www.mastercool.com/pages/vacuum_pumps.html
Pick out your model number and then click on "instructions" to download a manual. The most important thing is to change the oil frequently. This unit is used in HVAC to draw a vacuum on an evacuated AC system after repairs were made to insure it is free of any condensables.

I need some help knowing the pump I need


Since adobe air is out of business, you will have to make one of the dial 230 volt pumps fit in its place. I cut a little notch into the media support tray to fit mine.
As far as the pump size goes, the orange 230 volt is somewhere around 11'000cfm or bigger and works just fine in my precooler.

Low voltage wires


I just tested a mastercool control box and found these 4 control wire colors:

Red (24v supply)
White (pump)
Green (low blower)
Yellow (high blower)

The yellow acted as a common for testing when the blower was not on high.

Blower on low just green has 24v.
Blower on high green and yellow have 24v.

If there was a fifth wire added hopefully it would be a ground wire.

There was also the low gauge wires that were black, white, and ground that were not control wires and delivered power to the control box.
