around or underneath the oven.
I. UNLOADING/UNPACKING
YourMiddlebyMarshallOvensareshippedpartiallyassembled.
Each oven section will arrive in its own crate of the following
size and weight:
PS360U/PS360L PS360WB-U/PS360WB-L
Length: 72 (183cm) 66 (167cm)
Width: 48 (122cm) 57 (144cm)
Height: 60 (152cm) 50 (127cm)
Weight: 1675 lbs. (760kg) 1750 lbs. (780kg)
If you ordered stands for your ovens, they are shipped in
separate crates.
When your common carrier or truck line notifies you of delivery,
you must have a forklift at the facility to unload the crate(s).
If you have a door that is wider than the ovens, simply move the
ovens into your facility and set up an appointment with your
Middleby Marshall Authorized Installer.
NOTE: The width of each oven can be reduced by about 1"
(25mm) by removing the window from the oven. Window
disassembly instructions are in the Cleaning section of this
Owners Manual.
If the ovens are wider than your door opening, the oven will
have to be dismantled according to the directions in the Pre-
Installation Procedures Manual.

II. INSTALLATION, PREPARATION, AND
SUPPLY
When preparing the oven for installation at a location, the latest
International, National or Local Requirements should be
adhered to.
The ovens must be installed on an even (level) non-flammable
flooring and any adjacent walls must be non-flammable. The
minimum allowed distance from the rear of the oven to the wall
is 12 (30cm).
The ovens can be supported only by legs. No casters are
allowed. Itshouldbemadecertainthattherearenoobstructions
located around or underneath the oven that interfere with air
circulation.
The ovens must be installed under a ventilating hood with
electrical exhaust air sensing control.
The gas supply connection should be according to applicable
ISO-228-1 or ISO-7-1 recommendations.
Normally, the oven is preparted and adjusted to the specific
gas type used by the customer. Before operating the oven,
check the label on the oven and also on the packaging that the
gas type indicated matches the local supply at the installation.
If not, refer to Section VI, PREPARATION FOR VARIOUS
GASES, in this chapter and convert as directed.
All installations, conversions and service work must be
performed by an Authorized Service Agent according to the
instructions supplied by the manufacturer.
When converting from one gas type to a different type, the
orifices supplied with the conversion kit must be checked for
proper size as specified in this manual to assure that the oven
is operating at the nominal rated input.

III. VENTILATION SYSTEM
IMPORTANT
Where international, national, or local codes require
the installation of fire suppression equipment or other
supplementary equipment, DO NOT mount the
equipment directly to the oven.
MOUNTING SUCH EQUIPMENT ON THE OVEN MAY:
 VOID AGENCY CERTIFICATIONS
 RESTRICT SERVICE ACCESS
 LEAD TO INCREASED SERVICE EXPENSES FOR
THE OWNER
REQUIREMENTS
A mechanically driven ventilation system is required for the
oven.
PROPER VENTILATION OF THE OVEN IS THE
RESPONSIBILITY OF THE OWNER.
RECOMMENDATIONS
NOTE THAT THE HOOD DIMENSIONS SHOWN IN FIG-
URE 2-1 (PREVIOUS PAGE) ARE RECOMMENDATIONS
ONLY. INTERNATIONAL, NATIONAL, AND LOCAL
CODES WILL VARY, AND MUST BE FOLLOWED WHEN
INSTALLING THE VENTILATION SYSTEM. ANY AP-
PLICABLE INTERNATIONAL, NATIONAL, AND LOCAL
CODES SUPERSEDE THE RECOMMENDATIONS
SHOWN IN THIS MANUAL.
The rate of air flow exhausted through the ventilation system
may vary depending on the oven configuration and hood
design. Consult the hood manufacturer or ventilation engineer
for these specifications.
To avoid a negative pressure condition in the kitchen area,
return air must be brought back to replenish the air that was
exhausted. A negative pressure in the kitchen can cause heat-
related problems to the oven components as if there were no
ventilation at all. The best method of supplying return air is
through the heating, ventilation and air conditioning (HVAC)
system. Through the HVAC system, the air can be temperature-
controlled for summer and winter. Return air can also be
brought in directly from outside the building, but detrimental
affects can result from extreme seasonal hot and cold
temperatures from the outdoors.
NOTE: Return air from the mechanically driven system must
not blow at opening of bake chamber. Poor oven baking
performance will result.
OTHER VENTILATION CONCERNS
 Special locations, conditions, or problems may require the
services of a ventilation engineer or specialist.
 Inadequate ventilation can inhibit oven performance.
 It is recommended that the ventilation system and duct
work be checked at prevailing intervals as specified by the
hood manufacturer and/or HVAC engineer or specialist.

JOINING THE OVEN BODIES
For TANDEM and DOUBLE TANDEM installations, perform
Steps 1-7 to join the ovens.
For TRI TANDEM installations, perform Steps 1-7 to join two of
the ovens together, and ensure that they are level; then, repeat
Steps 1-7 to join the third oven to the two that are assembled.
For QUAD TANDEM installations, perform Steps 1-7 for EACH
PAIR of ovens, producing two sets of two joined ovens. Do not
assemble the center bridge section at this time.
1. Determine the proper position of the ovens by referring to
Figure 2-15. Then, move the ovens to their approximate
final locations.
NOTE: The Sealing Gasket Assembly is shown attached
to the left oven in Figure 2-15, but may be pre-mounted to
EITHER of the two ovens.
2. Remove therearaxialcooling
fans that are adjacent to the
mating sides of the ovens, as

10. Attach the two angled support
brackets between the two
center ovens, as shown in
Figures 2-22a and 2-22b.
Note that a LOWER OVEN
(PS360L, PS360WB-L) uses
different support brackets for
the front and rear, while an
UPPER OVEN (PS360U,
PS360WB-U) uses identical
brackets on the front and rear.
