AC-215 / AC-210 E AC Power Conditioner
Thank you for purchasing the Furman
AC-215 / AC-210 E Power Conditioner. For
over 30 years, Furman has pioneered the
development and manufacturing of AC power
products for the most demanding audio,
video, and broadcast professionals. Furman’s
Series Multi-Stage Protection Plus (SMP+)
delivers the purest AC power and the most
comprehensive protection available – going far
beyond what is found in traditional surge strips.
Today’s power grid typically experiences
numerous electrical surges and spikes on a
daily basis. At best, these irregularities can
degrade your equipment’s performance; at
worst, they can severely damage individual
components or your entire system. Furman’s
SMP+ circuit offers the highest degree of
protection available.
The AC-215 / AC-210 E is specifically
designed for today’s diverse power purification
applications. This compact unit can be
mounted behind a projector; LCD or plasma
screen; inside of a rack; on a wall or a
ceiling; or any other location where discrete
power conditioning is needed. Its compact,
streamlined design integrates easily into any
system, and the included brackets allow you to
mount it inconspicuously.

Safety Information
To obtain best results from your Furman
AC-215 / AC-210 E Power Conditioner, please
be sure to read this manual carefully before
To reduce the risk of electrical shock, do not
expose this equipment to rain or moisture.
Dangerous high voltages are present inside
the enclosure. Do not remove the covers.
There are no user serviceable parts inside.
Refer servicing to qualified personnel only.
The lightning flash with an arrowhead symbol,
(within an equilateral triangle) is intended to
alert the user to the presence of un-insulated
dangerous voltage within the product’s
enclosure that may be of sufficient magnitude
to constitute a risk of electric shock.
Important Safety Instructions
1. Please read and observe all safety and
operating instructions before installing your
unit. Retain these instructions for future
AC-215 / AC-210 E AC Power Conditioner
2. Your unit should not be used near water – for
example, near a bathtub, washbowl, kitchen
sink, laundry tub, in a wet basement, near a
swimming pool, etc.
3. Do not place your unit near heat sources
such as radiators, heat registers, stoves or
other appliances that produce heat.
4. The unit should only be connected to a 120
VAC, 60Hz, 15 Amp [230 VAC and10 Amp for
the AC-210 E] grounded electrical outlet. Do
not defeat the ground or change polarization of
the power plug.
5. Route the power cord and other cables so
that they are not likely to be walked on, tripped
over, or stressed. Pay particular attention to
the condition of the cords and cables at the
plugs, and the point where they exit your unit.
To prevent risk of fire or injury, damaged cords
and cables should be replaced immediately.
6. Clean your unit with a damp cloth only. Do
not use solvents or abrasive cleaners. Never
pour liquid on or into the unit.
7. Your unit should be serviced by qualified
service personnel when:
• The power supply cord or the plug
has been frayed, kinked, or cut.
• Objects have fallen or liquid has
spilled into the unit.
• The unit has been exposed to rain or
other moisture.
• The unit does not appear to operate
normally or exhibits a marked change
in performance.
• The unit has been dropped, or the
enclosure damaged.
invalidate the warranty.
9. Do not attempt to service yourunit beyond
what is described in this manual. All other
servicing should be referred to qualified service
While the AC power delivered by today’s
overworked and outdated power grid may be
adequate for typical lighting and consumer
products, it is well below the level of quality
needed for connecting sensitive audio and
video equipment. With the average investment
in home theater equipment steadily rising, it’s
more important than ever to purify or clean
your incoming AC power.
Furman’s Series Multi-Stage Protection Plus
(SMP+) circuitry incorporates Linear Filtering
Technology (LiFT) to insure that flat screen
televisions, projectors, processors, and other
sensitive audio/video components are fed
linearly-filtered AC power. This dramatically
reduces noise, ensuring consistent, peak
performance from your equipment. The result
is better performance, a better quality picture,
and less wear on your components.
Another feature unique to Furman’s SMP+
circuit is automatic Extreme Voltage Shutdown
(EVS) with a TVZ MOV. Extreme voltages are
statistically the most common, damaging AC
event. The Extreme Voltage Shutdown circuit
automatically turns off the AC-215 / AC-210 E
when it is fed 137 volts [270VAC for the AC-210
E or 260VAC for the AC-210 E UK] or higher,
protecting itself and connected equipment from
the extreme voltage. Only Furman offers this
advanced degree of protection.
8. Your unit requires that a safety ground be
present for proper operation. Any attempt
to operate the unit without a safety ground
is considered improper operation and could
AC-215 / AC-210 E AC Power Conditioner
Extreme Voltage Shutdown Indicator
The AC Series SMP+ circuit senses voltages
that are high enough to cause damage to your
components, and shuts the power down before
damage can occur.
The Extreme Voltage Shutdown LED is
normally off. If an input voltage in excess of
137VAC [270VAC for the AC-210 E or 260VAC
for the AC-210 E UK] is sensed, either on initial
power-up or during normal operation, the AC215 / AC-210 E will shut off power and this
indicator will light.
NOTE: If the mains power is above the high
cutoff voltage and has caused the unit to
remove power from its outlets, it cannot restore
power without the operator manually turning
the unit off, then on again. Avoid turning the
unit back on, without first checking the source
of the problem, and perhaps changing the AC
Protection OK Indicator
Although the Furman SMP+ circuit assures
protection from transient voltage spikes and
surges, nature has a way of occasionally
creating electrical forces that are beyond the
capabilities of any TVSS device to absorb
without some degree of damage. In the rare
instance that this occurs, the green “Protection
OK” LED indicator located on your front panel
will turn off. If this happens, some level of
protection from voltage surges will remain,
but the Furman’s clamping voltage rating will
be compromised. The unit must be returned
to Furman Sound, or an authorized Furman
Service center for repair.
Symptom: No power to the AC outlets.
Possible Cause: Circuit breaker has
tripped due to excessive load.
Action Needed: Unplug one piece of
equipment from the AC-215 / AC-210
E, and push the re-set tab into the
Circuit breaker bezel.
Symptom: No power to the AC outlets, even
after the Circuit breaker has been re-set.
Possible Cause: Protection devices
are damaged.
AC-215 / AC-210 E AC Power Conditioner
The AC-215 / AC-210 E can be conveniently and inconspicuously mounted within an equipment
rack or on the rear panel of your video display, using the included brackets.
Refer to the illustrations below for instructions.
The brackets can be positioned facing in or out as shown to best allow for different types of installations.
