Operation

Step

Step

Description:

Step

A.

The

Compressor,

pumps

the

air

pressure

inside

a

storage

tank,

located

under

the

Compressor

Motor.

StQp

B.

NQxt

in

line

is

a

storage

tank.

(to

hold

a

large

volume

of

air)

Step

C. The

air

is

piped

through

an

Air

Dryer,

this

removes

moisture

from

the

compressed

air.

Air

Filters

may

have

been

placed

before

and

after

the

Air

Dryer.

Step

D.

After

the

Air

Dryer,

the

air

is

piped

to

the

Platform,

"Wack-A-Demon"

and

the

"Balloon

Blow

Up".

Step

E.

(Refer

to

Drawing

Page

3-014)

Upon

reaching

the

platform,

the

air

is

first·applied

to

a

main

line

shut

off

valve,

then

to

the

Dual

Pressure

Manifold

System.

It

consists

of

first,

an

Air

Filter

(A),

to

remove

any

impurities

from

the

air.

Then

it

goes

through

2

air

Regulators

that

control

the

amount

of

air

pressure

allowed

to

pass

through

them.

(Regulator

(B)

is

set

at

40

P.S.I.

and

Regulator

(C)

is

set

at

80

P.S.I.)

The 2

air

lines

are

next

applied

to

an

electronically

controlled

4

way

valve.

This

valve

will

decide

whether

the

show

is

operated

at

a 80

P.S.I.

pressure

or

at

a 40

P.S.I.

pressure.

The

last

stop

in

the

Dual

Pressure

Manifold

System

is

a

Shuttle

Cock.

When

the

40

P.S.I.

mode

is

selected,

it

will

quickly

allow

the

40

P.S.I.

pressure

to

pass

by

while

closing

off

the

80

P.S.I.

line.

Step

F.

The

next

step

in

the

air

system

is

a

Distribution

Manifold.

It

simply

allows

you

to

branch

off

your

main

line

into

several

smaller

lines,

these

ate

your

individual

character

lines.

Step

G. The

air

is

now

run

under

the

stage

to

the

"In

Line

Lubricator".

It

will

put

a

vapor

of

10wt.

oil

into

the

air

flow.

It

is

located

at

the

Character's

Trap

Door

in

the

platform.

To

set

the

lubricator,

close

it

until

it

lightly

seats,

then

open

it

approximately

1/4

turn

of

the

adjustment

knob.

The

lubricator

should

not

use

more

than

one

bowl

(filled

to

the

"Full

Line")

every

2

to

3

weeks.

Step

H. The

Character

Valve

Bank

is

a

grouping

of

several

individual

4 way

valves,

with

common

air

supply

and

air

exhaust

internal

ports.
