Thank you for purchasing a Furman Series II

Power Conditioner, and Congratulations on
your choice. The Series II power conditioners

feature Furman’s revolutionary Series Multi­Stage Protection Plus (SMP+) circuit, as well
as our exclusive Linear Filtering Technology
(LiFT). Together, these technologies comprise
what is, without question, the world’s most
advanced and comprehensive transient
voltage surge suppressor / conditioner.

SMP+ (Series Multi-Stage Protection
Plus)

Furman’s SMP+ surge suppression virtually
eliminates service calls. Traditional surge
suppression circuits “sacrice” themselves
when exposed to multiple transient voltage
spikes, requiring the dismantling of your
system, and repair of your surge suppressor.
Not so with SMP+. With Furman’s SMP+,
damaging transient voltages are safely
absorbed, clamped, and dissipated.

Unique to Furman’s SMP+ is its unparalleled
clamping voltage. While other designs offer
clamping voltages that are well above 330
Vpk, Furman’s SMP+ clamps at 188 Vpk,
(133 VAC RMS). This unprecedented level
of protection is only available with Furman’s
SMP+ technology. Additionally, Furman’s

trusted over-voltage circuitry protects against
all too frequent accidental connections to 208
or 240 VAC, by shutting off the incoming power
until the over voltage condition is corrected.

[For E versions: Furman’s SMP+ clamps at 376

VpK, (266 VAC RMS.)]

LiFT (Linear Filtering Technology)

Unfortunately, traditional AC lter - conditioners
have been designed for unrealistic laboratory
conditions. Prior technologies, whether
multiple pole lter or conventional series
mode, could actually harm audio and video
performance more than they help, due to the
resonant peaking of their antiquated, non-linear
designs. Under certain conditions, these
designs can actually add more than 10 dB of
noise to the incoming AC line! Worse still, lost
digital data, the need to re-boot digital pre-sets,
or destroyed digital converters are frequently
caused by excessive voltage spikes and AC
noise contaminating the equipment ground.
Furman’s SMP+ with LiFT takes another
approach, ensuring optimal performance
through linear ltering and no leakage to
ground.

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. Refer
servicing to qualied personnel only. The
lightning ash with an arrowhead symbol, is
intended to alert the user to the presence of
un-insulated dangerous voltage within the
product’s enclosure that may be of sufcient
magnitude to constitute a risk of electric shock.

(Please read prior to installation)

1. Please read and observe all safety and
operating instructions before installing your
Series II unit. Retain these instructions for
future reference.

2. Your Series II 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 Series II unit near heat
sources such as radiators, heat registers,
stoves, or other appliances that produce heat.

4. The PL-PRO II, PL-PRO D II, and PM-PRO
II should only be connected to a 120 VAC,
60Hz, 20 amp grounded electrical outlet. Do
not defeat the ground or change polarization of
the power plug. (E versions 220 – 240 VAC 50 Hz., J

versions 100 – 120 VAC 50 Hz.)

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
Series II unit. To prevent risk of re or injury,
damaged cords and cables should be replaced
immediately.

6. Clean your Series II unit with a damp cloth
only. Do not use solvents or abrasive cleaners.
Never pour liquid on or into the unit.

7. Your Series II unit should be serviced by
qualied 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.

• The “Protection OK” indicator is not lit.

• The unit has been dropped, or the enclosure
has been damaged.

• The retractable LED lights have failed. (not

applicable to the PM-PRO II)

8. Your Series II 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 invalidate the warranty.
