Mastercool Cooler Owner Manual – Where To Find One

The Mastercool cooler is popular in Arizona, and Mr. A receives requests to install them occasionally as they are said to cool better than typical evaporative coolers. These units apparently also last longer than most, so it is not uncommon to learn that the home owner has already acquired a used model, and of course the owner manual or installation guide is not included with these units.

AJ and I are skilled at searching the Internet but this Mastercool search had us stumped.

Luckily I happened to find this post at FixYa: Problem for Mastercool 67471 Evaporative Cooler Air Conditioner I need a wiring diagram for a mastercool which explained “Symphony is the new name for the old Adobe Air brand’s Mastercool.” No wonder I’ve had such a difficult time finding information on the Mastercool cooler. Apparently they are being sold under this new name.

Upon opening the PDF file I discovered a company name at the bottom: Impco, and thankfully they had included their website address.

As it turns out, the PDF linked to at FixYa was not exactly the model I needed to know about.

I decided to put in a call to the company when I saw that it is located in Phoenix, Arizona.  The nice woman I spoke with helped me navigate the website so that I could find the proper unit which is the Ducted Symphony Aspen.

This page here contains all the owner manuals for the Symphony series coolers.

If you own your own home, and you’re looking for a way to save money on your electricity bill, check into having an evaporative cooler installed. 

I speak from experience: I have lived with evaporative cooling for 32 years of my life.  It is definitely an effective way to save money during the hot summer when we’re experiencing that famed “dry heat” that everyone brags about.  My electricity bills were always under $100 when we had only evap cooling (and a gas stove and water heater), now our bills can run as much as five times that amount during the hottest months of the summer.

The best solution is to have both air conditioning and the evap unit since it does get uncomfortable during our monsoon using the evaporative cooler. If you have both, never use them at the same time.  Please see my tips for using home air conditioning to learn more.

  1. Gosh. Every time I hear about your AC bills, I get scared. Between the heat and the humidity, the bill that comes this month should be a shocker…this month my unit has been thumping away all day and night, almost nonstop. Except for those two wonderful 80-degree days. And right now: it’s raining!! 🙂 🙂
