CHECK

Measure

leakage

current

to

a

known

earth

ground

(water

pipe,

conduit,

etc.)

by

connecting

a

leakage

such

as

Simpson

Model

229-2

or

equivalent

between

the

earth

ground

and

all

exposed

,

metal

parts

of

the

appliance

(input/output

etc.).

Plug

the

AC

line

of

the

appliance

directly

into

a

120V

and

turn

the

measured

must

not

2.PRODUCT

SAFETY

NOTICE

Many

electrical

and

mechanical

parts

in

the

appli-

ance

have

special

safety

These

are

often

not

evident

from

visual

inspection

nor

the

protection

afforded

by

them

necessarily

can

be

ob-

tained

by

using

replacement

components

rated

for

vol-

tage,

wattage,

etc.

Replacement

parts

which

have

these

special

safety

characteristics

are

identified

in

this

Service

Manual.

Electrical

components

having

such

features

are

identified

by

marking

with

a

A

on

the

schematics

and

on

the

parts

list

in

this

Service

Manual.

The

use

of

a

substitute

component

which

dose

not

have

the

same

safety

characteristics

as

the

PIONEER

recommended

replacement

one,

shown

in

the

parts

list

in

this

Service

Manual,

may

create

shock,

are

deliberately

shorted.

The
