A. O. Smith HEATMASTER User Manual

THE EVOLUTION CONTINUES...

“Great idea. Easy to sell. No brainer for the contractor. Why not use a higher ambient motor for all applications, plus it has a great
warranty at an affordable price.”

Dennis Cooney - Des Moines, IA

“The new A. O. Smith line of HeatMaster motors are the ticket. I can stock four motors that will replace most condenser fan applications.
And for only a couple of dollars more the customers gets a 70°C motor to reduce call backs and a 3 year warranty. It doesn’t get much
better than that.”

John Payne - Alexandria, VA

“With an ambient temperature rating of 158°F and a thermal overload set at an amazing 300°F, The HeatMaster line of motors is
providing unmatched durability and value. The bar has definitely been raised!”

Todd Hartson - Owosso, MI

“The HeatMaster motor is becoming very popular with contractors. The high temperature application, thru bolts and all angle mount is
preferred over other condenser motors. The three year warranty is a great bonus!”

Rich Snyder - Lansing, MI

“The HeatMaster motor line is a product offering that has been needed in the industry for a long time.”

Joe Gregory - Park Hill, KY

“United Refrigeration’s branch in Las Vegas, NV is stocking your HeatMaster. Our customers like all of the features of this motor and
the 3 year warranty. I think this motor is the best in the field.”

William Kerr - Philadelphia, PA

“The HeatMaster line offers a new level of service, protection and commitment to the HVAC/R industry with its class F insulation for
superior quality and a 3 year warranty which proves this motor is the real deal. Plus these motors are affordably priced so they won’t
cost you an arm and a leg.”

Brandon Clark - Denton, TX

“I tell my customers not to overlook the HeatMaster 70° motor. I tell them they need to supply their customers with a motor that can
withstand the Phoenix heat.

Wally Terry - Phoenix, AZ

“We have customers coming in looking for the 70°C motor. You guys hit a home run on this one.

Karl Weiss - Scottsdale, AZ

“I’m glad that we finally have a product that will not only compete with, but will send the competition back to the drawing board. And
the 3 year warranty is pretty tough to beat! Keep up the good work.

Frank Sulima - Mississauga, ON

“We have several contractors that will only carry the HeatMaster line on the service trucks. With south Texas 100° ambient days why
trust anything else.”

Darryl Loggin - San Antonio, TX

“Go to the head of the class A. O. Smith! The HeatMaster not only reduces wholesaler sku’s it also helps the contractor reduce the
inventory investment of each company’s service truck. First to the market with great products, leaders in the HVAC industry with
innovative ideas.
