First

 

start

up

 

The

 

electrical

 

protection

 

system

 

must

 

undergo

 

a

 

functional

 

test

 

before

 

the

 

appliance

 

is

 

put

 

into

 

operation.

 

The

 

appliance

 

must

 

be

 

installed

 

and/or

 

inspected

 

by

 

qualified

 

staff,

 

who

 

will

 

start

 

it

 

up

 

for

 

the

 

first

 

time

 

and

 

provide

 

the

 

relevant

 

operating

 

instructions.

 

 

Preparing

 

for

 

use

 

(important)

 

The

 

rinse

 

aid

 

dispenser

 

is

 

fitted

 

on

 

all

 

models,

 

the

 

detergent

 

dispenser

 

only

 

on

 

some.

 

If

 

both

 

dispensers

 

are

 

present

 

put

 

the

 

external

 

detergent

 

and

 

rinse

 

aid

 

containers

 

in

 

place

 

and

 

insert

 

the

 

respective

 

intake

 

hoses

 

on

 

the

Before

 

inserting

 

the

 

hoses

 

into

 

the

 

containers,

 

fit

 

the

 

weights

 

(needed

 

to

 

ensure

 

that

 

they

 

always

 

draw

 

in

 

liquid

 

from

 

the

 

bottoms

 

of

 

the

 

containers)

 

and

 

the

 

filters

 

onto

 

their

 

ends

 

as

 

shown.

 

If

 

the

 

detergent

 

dispenser

 

is

 

not

 

factory

fitted,

 

it

 

can

 

be

 

retrofitted

 

after

 

ordering

 

the

 

relative

 

kit.

 

 

 

As

 

an

 

alternative

 

an

 

external

 

dispenser

 

can

 

be

 

fitted,

 

making

 

the

 

electrical

 

connection

 

by

 

means

 

of

 

an

 

H05

 

RN

F

 

2x0.5

 

mm

 

electrical

 

cable,

 

which

 

can

 

be

 

laid

 

along

 

the

 

route

 

shown

 

in

 

the

 

TECHNICAL

 

DATA

 

diagram

 

and

 

connected

 

as

 

shown

 

in

 

the

 

wiring

 

diagram

 

supplied

 

with

 

the

 

warewasher.

 

The

 

dispenser

 

must

 

operate

 

on

 

230V/50

 

Hz

 

with

 

maximum

 

power

 

absorption

 

of

 

15

 

W

.

 

Connect

 

to

 

the

 

detergent

 

dispenser

 

outside

 

the

 

warewasher

 

using

 

the

 

red

 

hose

 

mentioned

 

above.

 

 

 

 

 

  

IMPORTANT:

  

 

 

Whenever

 

the

 

type

 

of

 

detergent

 

or

 

rinse

 

aid

 

is

 

changed,

 

it

 

is

 

ABSOLUTELY

 

ESSENTIAL

 

to

 

flush

 

out

 

the

 

peristaltic

 

pumps

 

by

 

placing

 

the

 

external

 

intake

 

pipes

 

in

 

water

 

for

 

a

 

few

 

cycles.

 

 

Always

 

use

 

only

 

products

 

specifically

 

recommended

 

for

 

use

 

in

 

a

 

warewasher.

 

 

Failure

 

to

 

comply

 

with

 

this

 

recommendation

 

leads

 

to

 

forfeiture

 

of

 

the

 

warranty

 

entitlement

 

on

 

the

 

appliance’s

 

water

 

system.
