Measure

leakage

current

to

a

(water

pipe,

conduit,

etc.)

by

connecting

a

such

as

Simpson

or

equivalent

between

the

earth

and

all

exposed

directly

into

a

120V

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

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
