and
the
Force 40S
(Simutaneous
Coag
feature).
All
generators
are
configured
to
operate
at
220-240
V~
nominal.
A
kit
is
available
from
Valleylab
to
convert
the
generator
to
110-120
V-
operation.
The
differences
between

Responsibility of the Manufacturer
Valleylab
Inc
is
responsible
for
the
effects
on
safety,
reliability
and
performance
of
the
equipment
only
if:
—
©
assembly
operations,
extensions,
readjustments,
modifications
or
repairs
are
carried
out
by
persons
authorized
by Valleylab
Inc.
—
the
electrical
installation
of
the
relevant
room
complies
with
local
codes
and
requirements
such
as
IEC
and
BSI.
— the equipment is used in accordance with the instructions for use.
Environmental Conditions
Transport and Storage
Ambient Temperature: Between —40 and +70 degrees C.
Relative Humidity: Between 10% and 100%, noncondensing.
Atmospheric Pressure: Between 500 and 1060 millibar.
Operation
Ambient Temperature: Between +10 and +40 degrees C.
Relative Humidity: Between 30% and 75%, noncondensing.
Atmospheric Pressure: Between 700 and 1060 millibar.
Preparing the Generator for Use
The
electrosurgical
generator
may
be
placed
on
a
mounting
cart
(available
from
Valleylab)
or
be
installed
in
a
ceiling
mount
system.
It is
recommended
that
carts
have
conductive
wheels.
Refer
to
hospital
procedures
or
local
codes
for
detailed
information.
Provide
at
least
four
to
six
inches
of
space
around
the
sides
and
top
of
the
generator
for
convection
cooling.
Under
continuous
use
for
extended
periods
of
time,
it
is
normal
for
the
top
and
rear
panel
to
be
warm.
DANGER
Explosion
Hazard.
Do
not
install
the
electrosurgical
generator
in
areas
using
flammable
anesthetics,
gases,
liquids,
or
objects.

Power Requirements
The
Force

Electrosurgical
Generator
is
designed
to
operate
between
85
—
140
V~
or
170
-
280
V~,
50-60
Hz.
The
output
will
remain
constant
over
the
ranges
of
90-135
V~
or
180-270
V
~,
50-60 Hz.
Power Plug
The
Force
generator
is
shipped
with
a
hospital
grade
power
plug.
The
Valleylab
representative
in
your
country
will
equip
your
Valleylab
generator
with
the
proper
connector
for
your
operating
room,
if
different
from
that
supplied.
The
connector
meets
all
requirements
for
safe
grounding.
Its
purpose
should
not
be
defeated
by
using
extension
cords
or
three-prong
to
two-prong
adapters.
The
power
cord
assembly
should
be
periodically
inspected
by
qualified
personnel.
Cords
should
always
be
grasped
by
the
plug.
Do
not
pull on the
cord itself.
Proper Grounding
An
important
consideration
in
assuring
patient
safety
while
using
electrical
equipment
is
proper
grounding.
The
ground
wire
in
the
power
cable
is
connected
to
the
chassis
and
insures
that
no
dangerous
currents
will
flow
from
the
cabinet
of
the
generator
in
the
event
of
an
internal
electrical
failure.
Undesirable
50-60
Hz
leakage
currents
are
also
affected
by
the
polarization
of
the
input
50-60
Hz
power
to
the
generator.
It
is
the
responsibility
of
the
user
to
assure
proper
grounding
and
polarity
in
the
power
outlets
furnishing
power
to
the
Force
generator.
Preoperational Checkout
Refer to Section 5, Power Up Self-Test.
Routine Maintenance and Inspections
Valleylab
recommends
that
the
Force
generator
be
inspected
by
gualified
service
personnel
twice
a
year.
This
Service
Manual
describes
the
recommended
inspection,
testing,
and
calibration
procedures.
For
major
repairs,
the
generator
can
be
returned
to
Valleylab.
If
desired,
Valleylab
will
supply
any
parts
or
information
needed
to
repair
the
Force
generator.
Cleaning Instructions
Clean
the
generator
using
standard
hospital
procedures.
Use
a
mild
detergent
and
damp
cloth
to
clean
the
generator
cover,
keyboard
and
cord.
Do
not
allow
fluids
to
enter
the
chassis.
Do
not
use
alcohol,
caustic,
corrosive,
or
abrasive cleaning
materials.
The
generator
cannot
be
sterilized.

Directions
(For

Reusable
Handswitching
Pencils)
NOTE
These
directions
are
not
intended
for
electrosurgical
accessories
not
manufactured
by
Valleylab.
Refer to the instructions provided by the manufacturer.
Cleaning
1.
The
pencil
should
be
processed
with
other
delicate surgical
instruments
in
order
to
protect
the
electronic components.
2.
If
a
disposable
electrode
has
been
used
in
the
pencil,
remove
and
discard.
Remove
all
gross
matter
(blood,
mucus,
tissue)
by
wiping
the
entire pencil
with
a
cloth
or
gauze
pad
and
a
mild
cleaning
solution
or
blood
dissolving
detergent.
Remove
any
cleansing
agents
by
wiping
the
pencil
with
a
water-dampened
cloth.
Do
not
immerse
the
pencil
in
reprocessing
solutions.
3. Dry thoroughly.
4.
Sterilize
the
pencil
using
standard
hospital
procedures
for
Ethylene
Oxide
sterilization
or
steam
autoclave sterilization, following the handling recommendations below.
Ethylene Oxide (EtO) Processing
1.
Coil
the
cord
loosely
prior
to
inserting
the
pencil
into
an
EtO
pouch.
Tight
“bunching”
or
wrapping
of the
cord
will decrease
the useful life of
the
pencil.
2. Estimated number of uses when reprocessed by this method: 20
Steam Autoclave Processing
1. Do not autoclave the pencil unwrapped.
2.
Lay
the
pencil
body
in
the
center
of
the
wrapping
material
as
shown.
(Fig.
1)
3.
Fold
the
material
over
the
pencil
body
and
proceed
to
coil
the
cord
around
the
material
lengthwise
.
(Fig.
2)
NOTE
Keep
the
pencil
body,
dord
and
plug
connector
from
contacting
each
other
to
prolong
the
life
of
the pencil. Do not use rubber bands, string, or tape to secure the cord.
4.
Apply
a
second
wrapping
material
to
the
packet
produced
in
Step
2
above
(Fig.
3).
Tape
and
autoclave.
5.
Do
not
exceed
a
processing
temperature
of
135°C
(275°F
)
for
20
minutes.
The
number
of
uses
will be
reduced
when
this product
is steam
autoclaved.

Observe
the
generator.
If
an
error
code
(119-122) appears

Press
the

on
the

and
verify
that
the

illuminates,
discard
the
pencil.
NOTE
If
either

does
not
illuminate,
discard
the
pencil.
CAUTION
Inspect
the
pencil
and
cord
for
breaks,
cracks,
nicks,
or
other
damage
before
use.
If
damaged,
do
not
use.
Failure
to
observe
this
precaution
with
every
use
may
result
in
injury
or
electrical
shock
to
the
patient
or operating
room
personnel.
6. Place the generator in the Off mode until ready for surgery.

Classification
Class I Equipment per IEC 601-1
Protection
against
electric
shock
is
provided
by
connection
of
accessible
conductive
parts
to
the
protective
earth
conductor
in
such
a
way
that
they
cannot
become
live
in
the
event
of
a
failure
of
basic
insulation.
Type CF Equipment per IEC 601-1
The
Force
30,40
provides
a
high
degree
of
protection
against
electric
shock,
particularly
regarding
allowable
leakage
currents
and
has
a
CF
type
isolated
(floating)
applied
part.
The
applied
part
may
be
used
on
the
heart.
Defibrillator-Proof
The
neutral
electrode
terminals
of
the
Force
30,40
can
withstand
the
effects
of
defibrillator
discharge.
Drip Proof per IEC 601-1
The
Force
30,40
enclosure
will
prevent
reasonable
amounts
of
falling
liquid
from
interfering
with
the
generator’s safe and satisfactory operation.
Intermittent Operation
The
generator
is
cooled
by
natural
convection.
Under
maximum
power
setting
and
rated
load
conditions
(Pure
Cut,
300
watt
setting,
300
ohm
load)
the
Force
30,40
is
suitable
for
10
seconds
on,
30
seconds
off
operation
for
one
hour.
With
lesser
settings
and
other
load
impedances,
the
Force
30,40
can
be
used
for
greater
activation
durations
without
generating
excessive
internal
temperatures.
