EVERY HOUR OR SO WATER IS POURING OUT OF THE DRAIN, WHY?


There is a float in the evaporative cooler that will let water in when the trough is low and then when it fills, should shut the water off. I would check to make sure that the float arm is not corroded or misaligned.

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.

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.

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.
