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.

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.

The drain hose pumps out too much water.


Yes it is if it is very humid and hot you know your unit is working very good. You can take the hose out farther from that spot. Set up a bird bath and let the birds enjoy a bath. just a idea.

This unit is a cooling unit only. I don't know what switch you are looking at but I don't think it's for the evap. cooler(swamp cooler). I am in the Phoenix, Arizona area and it's very common to have a evap. cooler and a seperate heat/cool system as on the hottest days the evap. cooler doesn't cool enough. I hope this helps. Please give me a positive rating. Thank you.

Evap Cooler motor not cutting in


Look for a reset switch on the unit, press it and try again.

If there is no reset switch, unplug the unit entirely if possible, wait a minute and plug it back in.

Sometimes electronics get confused and need to start over. Let us know if that works.
