I. MODEL IDENTIFICATION
The Middleby™ Series PS200-R68 Ovens may be used
singly or stacked for use as double ovens.
The Series PS200-R68 single oven is mounted on a base
pad with 6" extension legs and casters. A double oven is
stacked and the lower oven is on a base pad with casters.
The ovens in a double oven operate completely indepen-
dent of one another. Both ovens use identical controls
and components. One can be serviced while the other is
operating.
The Series PS200-R68 Ovens can be ordered with the
conveyor drive at either the right end or left end of the
oven. Each oven is equipped with a remote control box.

SECTION 1
DESCRIPTION
II. PRINCIPLE OF AIR FLOW
Air is heated and then pulled through the fan which
pushes the air into the oven plenum and delivers heated
air into the air fingers. The fingers contain an inner plate
and outer plate which columnate the air and evenly
distribute heated air across the conveyor belt on which
the product rides. Air is then pulled back into the blower
and the process continues.
A. Heat Transfer and How It Works
1. Heat constantly moves from a warm object to a cold
object. Heat moves using three different paths which are
conduction, radiation and convection.
Conduction:
This path utilizes surface to surface con-
tact. The pizza dough in contact with the pan is a good
example of conduction.
Radiation:
This path has to do with objects radiating
heat. Dark objects absorb heat whereas light or shiny
objects reflect more heat. This is the reason that the
inside of the Middleby Series PS200-R68 Oven is light in
color to reflect more heat back to the product.
Convection:
This path has to do with moving amounts
of air. It explains why hot air will rise and cooler air
replaces hot air. An industrial application of this principle
is to incorporate a fan to force the hot air movement which
in turn will increase the heat transfer to the product.
The Middleby Series PS200-R68 Oven has a large fan to
move the hot air through the air fingers and onto the
product so the most efficient bake is achieved.
2. Temperature is the intensity of heat at the point which
it is sensed. As discussed above, heat flows by conduc-
tion, radiation and convection. The speed at which the
heat flows is determined by the temperature difference
between the oven and the food product. The larger the
difference the faster the heat flows to the item that is
being baked.

DESCRIPTION
II. PRINCIPLE OF AIR FLOW Continued
B. Air Fingers
The Middleby Series PS200-R68 Oven is a conveyorized
hot air oven employing vertical air streams (Figure1-3) to
give uniform and intensive heating. The columnated
vertical streams of hot air provide an exceptional heat
transfer rate and generally bake faster and at lower
temperatures than convection hot air or infrared heating
ovens.

This is accomplished with use of hot air fingers inside the
oven. The oven can accommodate up to 4 bottom air
fingers and 4 top air fingers. Standard PS200-R68 Series
ovens have 4 bottom fingers and 2 top fingers.

DESCRIPTION
Should a flame outage occur the control will close the
main gas control valve within 0.8 seconds and attempt to
reignite the pilot.
D. Electric Heaters (Electric Oven Only)
There are six heater elements mounted on the inside of
the rear panel. Each element is connected to a separate
electrical contact which is energized by the temperature
controller.
E. Front Window
The front window is used for viewing items being baked
and provides access to the oven for items which do not
require full bake time, such as sandwiches, cookies,
small items or cheese melting processes.
F. Cooling Fan
A cooling fan is located in the back of the oven. This
cooling fan blows cool air in through the machinery
compartment across the fan motor and conveyor motor
and control cabinet. The air is then exhausted through
the side of the cabinet and also out the back of the oven
compartment. Refer to Figure 1-6.
Another cooling fan is located in the bottom of each
control box. Air is drawn in through the louvers in the rear
of the control box and out through the fan. Refer to Figure
1-4.
Figure 1-6. Cooling Fan
III. COMPONENT FUNCTION
A. Conveyor
The conveyor is driven by a variable speed electric motor
operating through a gear reducer (See Figure 1-5). The
motor speed is controlled by a digital control. The stain-
less steel wire belt can travel in either direction and at
variable speeds from 3 minutes to 23 minutes.
Figure 1-5. Conveyor Drive Motor
B. Fan
The fan is located at the rear of the oven. This fan forces
heated air through the fingers. The fan switch has two
positions and must be "on" for oven warm up and bake
and for the conveyor to run.
C. Gas Burner (Gas Oven Only)
With the heat and blower switches ON the gas burner
heats the air as the air enters the main blowers to
maintain the set temperature. The burner flame is ignited
and monitored by a solid state burner control device.

DESCRIPTION
G. Air Fingers
The Air Finger Assemblies are made up of three parts as
follows (See Figure 1-7):
1. Outer Plate - The Outer Plate is the removable cover
with tapered holes, which directs the air stream onto the
product to be baked.
2. Inner Plate -The Inner Plate is vital to forming the
columnated air jets. It must be assembled onto the
manifold with its holes lined up with outer plate holes.
The inner plate is also manufactured with no rows of
holes. This type of finger is a non-columnating air finger.
3. Manifold - The Manifold is the assembly which slides
on tracks into the oven plenum.
4. Blank Plates- The Blank Plates are installed on the
plenum where air fingers are not required.
NOTE: On a PS200-R68 Series Red Lobster oven the 2 upper fingers (M3) have 3 rows of holes in the outer plate
and a non-columnating inner plate. The 4 bottom fingers (M6) have 6 rows of holes completely across the inner and
outer plates.

INSTALLATION
NOTE: For U.S. installations the installation must conform with local codes or in absence of local codes, with
ANSI Z223.1-latest edition and electrical code ANSI/NFPA No. 70-latest edition.
NOTE: For Canadian Installations - The installation should be done in accordance with the CAN 1-B149.1 or .2
installation code and/or local code and the Canadian electrical code, Part 1, CGA C22.1 for the electrical features.
CAUTION: It is required that the oven be placed under a ventila-
tion hood for adequate air supply and ventilation.
CAUTION: A minimum clearance of 0" from non-drive end of
oven to wall, 18" from drive end of oven to wall and 6" from
rear wall to air openings at rear of unit must be maintained.
For servicing and cleaning a minimum of 18" clearance from
all walls and combustible materials is recommended.
CAUTION: Do not obstruct the flow of combustion and ventila-
tion air to and from your oven. Do not obstruct the ventilation
holes in the control panel, as these provide the combustion
air for the burner.
NOTE
There Must Be Adequate Clearance Between
Oven And Combustible Construction.
Clearance Must Also Be Provided For
Servicing And For Operation.
I. UNLOADING
Your Middleby Marshall Series PS200-R68 Oven(s)
is shipped partially assembled and it will arrive in a
carton.
Carton size for all Series 200-R68 Ovens is:
84"(2134mm) Long x
58" (1473mm) Wide x
44" (1118mm) High.
A Pre-installation Procedures Manual (MM P/N
88910-0009) is attached to the exterior wall of the
carton. This manual contains detailed instructions on
unpacking and moving the oven(s) into your facility.
When your common carrier or truck line notifies you
of delivery, you must have a forklift at the facility to
unload the carton(s).
Instructions for stacking the ovens are contained in
a separate manual issued to Middleby Marshall
Certified Installers.
If you have a door wider than the carton simply move
the carton into your facility and set up an appointment
with your Certified Middleby Marshall Installer.
If your door is narrower than the carton, then the oven
will have to be uncrated. Follow directions shown in
the Pre-Installation Procedures Manual.
Each crate must be examined before signing the Bill
of Lading. Report any visible damage caused by the
trucker in transit, and check for the proper number of
crates. If apparent damage is found, arrangements
should be made to file a claim against the carrier.
Interstate Commerce Regulations require that the
claim must be initiated by the consignee within 10
days from the date it is received.
