FINAL

CHECK

LIST

FOR

DISPENSER

INSTALLATION

1.

Is

the

dispenser

level?

2.

Has

all

internal

packing,

auger

shipping

block,

and

tape

been

removed?

3.

Are

all

electrical

and

water

connections

complete?

4.

Is

there

a

5"

clearance

on

all

sides

for

air

circulation?

(Required

when

an

ice

machine

is

placed

on

top.)

5.

Is

there

a

separate

drain

for

the

dispenser,

when

an

ice

machine

is

placed

on

top?

6.

Are

the

drains

vented?

7.

Has

the

ice

machine

(when

used)

been

secured

to

the

dispenser?

8.

Is

the

lower

back

panel

assembly

(Item

69,

Fig.

13)

on

the

dispenser?

This

should

be

in

place

before

the

dispenser

is

operated.

9.

When

the

actuator

is

depressed,

is

the

dispenser

operational.

10.

Has

the

dispenser

been

and

fastened

to

the

countertop?

11.

Have

the

carbonated

water

and

syrup

lines

been

checked

for

leaks?

NOTE:

When

installing

a

Manitowoc

ice

machine

on

top

of

this

dispenser,

it

is

important

to

correctly

set

the

ice

machine’s

ice

bridge

thickness.

The

thinner

the

ice

bridge

on

the

ice

machine,

the

better

the

ice

will

break

up

for

dispensing.

Too

thick

a

bridge

will

allow

ice

chunks

to

fall

into

the

bin

and

prevent

cubes

from

breaking

up

for

easy

dispensing.

This

will

cause

a

slower

dispensing

rate.

If

using

a

small-mouthed

glass,

2W

diameter,

or

smaller,

it

is

recommended

that

“dice”

size

cubes

be

used.

SERIAL

NUMBER

AND

ELECTRICAL

DATA

An

identification

plate

detailing

serial

number

and

electrical

data

is

located

on

the

dispenser’s

front

cover.

OPERATION

PRINCIPLES

(Countertop)

This

dispenser’s

electric

motor

is

coupled

directly

to

a

right

angle

gear

box

that

drives

through

a

W

pitch

positive

displacement

belt,

the

dispensing

auger,

and

an

agitator

auger.

The

dispensing

auger

turns

at

approximately

35

revolutions

per

minute,

and

the

agitator

turns

at

approximately

17

revolutions

per

minute

(see

Fig.

5).

The

dispenser

motor

is

activated

by

an

ice

delivery

switch

located

in

a

switch

control

box

enclosure

behind

the

upper

front

panel

of

the

dispenser.

The

ice

delivery

switch

is

closed

by

the

ice

delivery

actuator

lever,

which

is

activated

by

the

customer,

or

attendant,

when

ice

is

required

(see

Fig.

6A).

This

switch

controls

a

solid

state

relay

that

controls

power

to

the

dispenser

motor

(see

Fig.

9).

The

ice

deliver

rate

ranges

from

1.8

oz./sec.

to

0.8

oz./sec.,

depending

on

cube

size

and

bin

fullness.

NOTE:

Always

be

sure

electrical

power

is

disconnected

before

cleaning

or

performing

maintenance

on

this

dispenser.

on

the

Vt,

hp

capacitor

start

motor.

The

electronic

switch

(Item

57)

monitors

the

voltage

wave

forms

across

the

start

winding.

The

wave

form

displays

a

slight

dip

followed

by

a

rise

at

the

motor

shaft

speed

where

proper

switch

operation

should

occur

(75-80%

of

synchronous

speed).

The

electronic

switch

will

usually

fail

with

the

switch

(Triac)

in

the

open

mode

(nonconducting).

If

the

motor

won’t

start

and

run,

the

switch

can

be

tested

by

momentarily

jumping

the

device

across

OPERATION

THEORY

A

C0

2

cylinder

delivers

carbon

dioxide

(C0

2

)

gas

through

adjustable

C0

2

regulators

to

a

carbonator

tank

and

syrup

tanks.

None

of

the

above

are

furnished

with

this

dispenser.

Plain

water

is

piped

into

the

carbonator

tank,

and

the

regulated

C0

2

gas

is

also

piped

into

the

carbonator

tank.

A

pump

is

used

to

carbonate

the

water

with

the

C0

2

gas

and

is

then

pumped

to

a

cold

plate

where

the

water

is

cooled

by

use

of

the

ice

in

the

dispenser.

The

syrup

is

also

routed

through

the

cold

plate

to

be

cooled,

and

when

a

valve

is

opened,

the

syrup

is

forced

through

the

valve

by

the

regulated

C0

2

pressure

or

by

bag

in

box

pumps.

Syrup

and

carbonated

water

meet

at

the

dispensing

valve

resulting

in

a

carbonated

drink

being

dispensed

(see

Fig.

19

and

19A

for

plumbing

schematic).

CONNECTING

DRINK

LINES

Syrup

lines

and

water

line

have

been

connected

to

the

cold

plate

and

extended

out

the

rear

of

the

cabinet

(see

Fig.

13).

All

internal

syrup

and

carbonated

water

lines

are

internally

connected

between

the

cold

plate

and

the

dispensing

valves

at

the

factory.

NOTE:

Lines

can

be

routed

through

the

unit’s

base

by

removing

cover

inside

rear

panel.

Field

connections

of

the

syrup

lines

and

carbonated

water

lines

can

be

made

to

the

lines

extending

out

the

rear

of

the

dispenser

by

of

a

straight

hose

connector

and

crimping

tube

clamps

(O-clamps)

(see

Fig.

20).

Check

connection

for

leaks.

for

up

to

30

feet

of

line.

The

low

calorie

regulator

should

never

be
