INDUCER ASSEMBLY

When we put it all together, the

Performance™ 93 combines quality and

design to bring high efficiency and

comfort. You will enjoy the versatility

and ease of installation of this unit. The

Performance™ 93 is equipped for either

left- or right-side connections. Blower

speeds are easily adjustable with speed-

taps conveniently located on the control

center. A more efficient combustion

inducer allows for more use of 2-in. vent

and combustion-air piping, keeping

installation costs low.

As with other Carrier furnaces, this

model is designed to work as a part of the

total home comfort system which

includes elements for cooling, air

cleaning, humidification, ventilation,

and zoning.

THE PERFORMANCE™ 93

FEATURES/BENEFITS

ComfortHeat™ Technology

—The

Performance™ 93 has a 2-stage gas

valve to vary the amount of gas being

used from low-heat to high-heat stage.

The low-stage operation allows longer

running periods, which helps maintain

your most comfortable temperature,

prevents drafts, reduces noise, and

enhances the air quality of your home.

During the extreme cold, the high-heat

levels will run to ensure that you are still

comfortable.

Primary Heat Exchanger &

Serpentuff™ Secondary Heat

Exchanger

— The primary heat

exchanger is corrosion resistant and

maintains a proven track record for long-

term reliability and high-efficiency

performance. The secondary heat

exchanger is built with a patented

lamination process that bonds a

corrosion-proof lining of polypropylene

to a heavy, galvanized steel shell. The

unique secondary clamshell design

allows wider spacing between cells for

reduced air resistance through the

furnace, reduced load on the blower

motor, and reduced need for cleaning.

Power Heat™ Igniter

— Carrier’s

unique SiN igniter is not only physically

robust but it is also electrically robust. It is

capable of running at line voltage and

does not require complex voltage

regulators as do other brands. This unique

feature further enhances the reliability of

Performance™ 93 gas furnace and

continues Carrier’s tradition of

technology leadership and innovation in

providing a reliable and durable product.

ComfortFan™

— Improves comfort

all year long by allowing the

homeowner to select different fan

speeds during continuous fan operation

to achieve more or less airflow. This is

done right at the thermostat.

SmartEvap™

— This feature allows

your system to reduce summer time

humidity levels by nearly 10% over

standard systems.

Media Filter Cabinet

— Enhanced

indoor air quality in your home is made

easier with our media filter cabinet—a

standard accessory on all furnaces.

When installed as a part of your system,

this cabinet allows for an easy and

convenient addition of a Carrier high-

efficiency air filter.

Adaptive Logic Control Board

— This

self-adjusting control board contains a

microprocessor which automatically

calculates the precise amount of time

your furnace should run and whether it

should run in low-heat or high-heat

operation to obtain the best comfort and

energy efficiency. This control board

also includes an extensive

troubleshooting and component test

sequence that can monitor your heating

system to ensure that it is operating

properly.

4-Way Multipoise Design

— Allows

the Performance™ 93 to be installed in

an upflow, downflow, or horizontal

orientation. Factory configured for

upflow applications with only simple

drain connection changes required for

conversion to downflow or horizontal.

Warranties

— Limited Lifetime

Warranty on the heat exchangers for the

lifetime of original owner in single

family residence; 20 years in other

residential and commercial applications.

5 year Limited Warranty on entire unit.

Contact your dealer for details.

Direct or Non-Direct Venting

— The

Performance™ 93 can be installed as a 1

pipe/Non-Direct vent or 2 pipe/Direct

vent furnace. This provides added

flexibility to meet diverse installation

needs.

Two-Speed Inducer Motor

— This

motor works with the inducer fan to

optimize combustion efficiency and

exhaust the flue gases out of the house.

The motor has two speeds and an

incorporated fan to keep the motor cool

while reducing sound.

Permanent split capacitor (PSC)

Blower Motor

— The Performance™

93 has a PSC blower motor that has

several preselected fixed speeds which

can be customized to duct work

installation requirements. The motor has

a wide application of use, a basic control

scheme, and is extremely reliable.

Full Cabinet Insulation

— This

insulation completely surrounds the

internal furnace casing allowing for

reduced and dampened sounds and

maintained efficiencies.

Soft Motor Mounts

— These motor

mounts help to absorb shock, decrease

the vibration of the motor, and minimize

noise.
