TUNING

 

A

 

DUMP

 

&

 

FILL

 

MACHINE

 

SECTION

 

Tuning

 

is

 

essential

 

for

 

proper

 

cleaning;

 

do

 

not

 

skip

 

this

 

IMPORTANT

 

PROCEDURE

 

The

 

key

 

to

 

understanding

 

proper

 

tuning

 

is

 

to

 

realize

 

that

 

the

 

drain

 

sequence

 

cannot

 

be

 

changed.

 

It

 

is

 

a

 

fixed

 

time

 

function

 

and

 

the

 

regulator

 

of

 

the

 

cycle

 

between

 

wash

 

and

 

rinse.

  

Therefore,

 

all

 

tuning

 

is

 

accomplished

 

by

 

setting

 

or

 

adjusting

 

the

 

fill

 

cam

 

in

 

relationship

 

to

 

the

 

fixed

 

drain

 

cam.

 

The

 

goal

 

of

 

tuning

 

is

 

to

 

eliminate

 

all

 

soiled

 

wash

 

water

 

through

 

the

 

drain,

 

before

 

the

 

drain

 

closes.

  

A

 

sign

 

that

 

soiled

 

wash

 

water

 

has

 

exited

 

the

 

tank

 

will

 

be

 

the

 

typical

 

hollow

 

sound

 

of

 

a

 

pump

 

running

 

without

 

water.

   

 

It

 

is

 

at

 

this

 

point

 

that

 

the

 

H2O

 

(FILL)

 

cam

 

should

 

be

 

adjusted

 

so

 

the

 

water

 

solenoid

 

turns

 

the

 

fill

 

water

 

on.

 

That

 

function

 

is

 

controlled

 

by

 

the

 

adjustment

 

of

 

the

 

fill

 

cam.

  

For

 

optimum

 

results,

 

allow

 

the

 

fill

 

water

 

to

 

flush

 

the

 

interior

 

of

 

the

 

machine

 

for

 

a

 

few

 

seconds

 

before

 

the

 

drain

 

closes.

  

Once

 

the

 

drain

 

is

 

closed

 

the

 

fill

 

cycle

 

begins.

 

Fill

 

must

 

continue

 

until

 

full

 

spray

 

arm

 

pressure

 

is

 

reached.

 

This

 

can

 

be

 

verified

 

with

 

the

 

use

 

of

 

a

 

spray

 

arm

 

pressure

 

tester

 

(Kit

 

#088

1048)

 

attached

 

where

 

one

 

of

 

the

 

end

 

plugs

 

are

 

usually

 

screwed

 

into

 

the

 

lower

 

wash

 

arm.

 

The

 

tester

 

gauge

 

will

 

indicate

 

full

 

spray

 

arm

 

pressure

 

when

 

the

 

needle

 

stops

 

fluctuating

 

and

 

remains

 

steady.

 

Adjust

 

the

 

fill

 

cam

 

to

 

turn

 

the

 

water

 

OFF

 

when

 

this

 

point

 

of

 

steady

 

pressure

 

is

 

reached.

 

It

 

is

 

important

 

that

 

the

 

machine

 

is

 

not

 

overfilled.

  

Use

 

just

 

enough

 

water

 

to

 

reach

 

Full

 

Spray

Pressure

 

(FSP),

 

no

 

more

 

than

 

that

 

is

 

needed

 

for

operation.

If

 

a

 

pressure

 

gauge

 

tester

 

is

 

not

 

available,

 

an

 

approximation

 

of

 

full

 

spray

 

arm

 

pressure

 

could

 

be

 

determined

 

by

 

the

 

sound

 

of

 

the

 

spray

 

arms.

 

There

 

would

 

be

 

a

 

typical

 

continuous

 

swishing

 

sound

 

of

 

the

 

water

 

spraying.

  

Again,

 

when

 

this

 

sound

 

is

 

heard,

 

that

 

would

 

be

 

the

 

point

 

to

 

turn

 

the

 

water

 

OFF.

  

Seven

 

seconds

 

of

 

full

 

spray

 

arm

 

rinse

 

pressure

 

is

 

required

 

by

 

health

 

code.

 

In

 

the

 

event

 

that

 

air

 

is

 

trapped

 

in

 

the

 

pump

 

during

 

fill,

 

a

 

vapor

 

lock

 

can

 

occur

 

where

 

the

 

pump

 

is

 

turning

 

but

 

there

 

is

 

no

 

spraying.

  

 

If

 

this

 

vapor

 

lock

 

occurs,

 

check

 

incoming

 

water

 

temperature

 

and

 

reduce

 

the

 

temperature

 

if

 

it

 

is

 

above

 

140

150F.

   

Operating

 

temperature

 

of

 

120F

 

degrees

 

is

 

the

 

minimum,

 

130

140F

 

degrees

 

is

 

recommended.

 

If

 

the

 

problem

 

is

 

caused

 

by

 

low

 

water

 

pressure

 

to

 

the

 

machine,

 

then

 

see

 

the

 

Plumbing

 

Section

 

above

 

to

 

correct

 

that

 

condition.

 

If

 

vapor

 

lock

 

is

 

still

 

present,

 

electrically

 

stop

 

or

 

pause

 

the

 

pump

 

to

 

release

 

air.

   

This

 

machine

 

has

 

a

this

is
