Introduction

The

Force

Electrosurgical

Generators

are

designed

for

ceiling

or

mounting.

The

models

available

in

this

Force

series

are:

Force

30,

Force

40,

and

the

Force 40S

(Simutaneous

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

the

two

major

models

are

the

maximum

power

settings

and

the

number

of

available

functions.

These

differences

are

summarized

in

the

following

tables.

Preparing

the

for

Use

The

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

rear

panel

to

be

warm.

or

170

50-60

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.

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
