Cooking

Area

The

CTX

Model

has

a

26"

(660

mm)

long

cooking

deck

(chamber)

with a

16"

(406

wide

conveyor belt.

3.

Controller

The

Controller controls

both

the

temperature

and

conveyor belt

speed

(cook

time)

of

the

oven.

Cook

temperature

can

be

set

from

200°F

to

950°F

(93°C

to

509°C)

and

cook time

can

be

set

from

Infrared Heating

Panels

Patented

heating

panels

are

positioned

above

and

below

the

conveyor belt

of

each

oven

deck

(cham-

·

ber).

When

energized these panels

emit

infrared

long

waves.

These

waves

do

not

heat

the air

through

which

they

pass.

Instead

the

waves

are

absorbed

by

the

outer

surface

of

the product transported

through

the

oven

on

the

conveyorbelt.

Using

this application

food

is

placed

on

the conveyor

and

the

unique

properties

of

the

infrared

waves

cause

it

to

cook

from

the

outside to

the

center

in

traditional

fashion.

5.

Heat

Zones

The

heat

zones

refer

to

individual

areas

of

heat

control within a cooking

deck

(chamber).

The

deck

contains

two

heat

zones

(top

and

bottom).

Refer

to

Figure

1-4.

6.

Conveyor

The

conveyor

is

used

totransport

the

product

through

the

oven

deck

(chamber).

The

conveyor

is

made

up

of

a

frame

and

a stainless

steel

wire belt

which

can

travel

in

either direction

around

the

frame.

The

con-

veyor

can

travel

at

variable

speeds

and

the

speed

is

controlled

by

the

Controller.

The

speed

of

the

con-

veyor

determines

how

long

the

productwill

be

in

the

cooking

chamber which

is

the

cooking

time.

The

oven

chamber

is

18-1/2"

(470

mm)

wide

with

a

16"

(406

wide

conveyor

belt.

B.

Placement of Oven

Some

very

important

considerations

must

be

made

when

choosing

the

place

where

the

oven

is

to

oper-

ate.

1.

This

oven

is

conveyorized

and

operates

continu-

ously.lt

should

be

placed

so

it

fits

into

the

"flow"

of

the

operation.

2.

Drafts

entering

the

oven

chambers

can

cause

inconsistent

cooking

results.

Check

the

area

sur-

rounding

the

oven

and

eliminate

sources

of

drafts

such

as

open

windows

or

door's

and

.fans

or

other

appliances

that

cause

air circulation.

3.

Oven

should

be

positioned

so

hot

air

from

an-

other

piece

of

equipment

cannot

enter

oven

cooling

fan

air

intake

on

the

control

compartment.

Serious

problems

could

occur.

NOTE:

To

validate

a

new

oven(s)

warranty a

factory

certifiedinstaller must verify that

Steps

C

thru

K

have

been

performedcorrectly.

Unpacking

Oven

The ovencomponents should be moved as close as

possible to final location before being assembled/

stacked. The oven setting on its bottom, requires

door openings wider than 26-3/4" (679 mm).

Open carton and remove it from around oven, then

remove the empty carton from the area. Directions

for removing the wooden skid are on the following

page.

All wiring and electrical connections required forthe oven(s) must be performed by a certified electrician. Each

oven must be wired according to the electrical specification for the oven rating. See chart below and electrical

schematics in Section 7.

The G-26 can bewired for 208

or

240VAC, 50/60Hz, 1 phase powersupply. 240V is recommended because of

voltage fluctuations from the local powercompa.ny. A drop in voltage will also cause the oven's wattage to drop.

Each oven must be on a separate 40 amp breaker. A 50 Amp-250V NEMA6-50 receptacle is required for each

oven to accept the oven plug. The receptacle is available (optional) through CTX, PIN ACRG24.
