CAUTION

UNCRATING

The oven will arrive completely assembled inside a wood frame. Prior to uncrating move the oven
as close to its nal location as practical. This will protect it from damage associated with moving
(scratches, dings, dropping).

Some hardware, (i.e. casters, legs, stacking kits) may be shipped inside the oven. Please
remove any items before continuing.

It may be necessary during the installation to place the unit on its side (i.e. leg, caster installation, t
through doors, etc) follow these guidelines to lessen the risk of damage to the unit.

Placing the unit onto its side:

1. Have oven completely uncrated and sitting
on its shipping crate.

2. When using a dolly, place a piece of plywood
on top of the dolly to distribute the weight
evenly. Also have a piece of cardboard or
micro-foam between plywood and oven to
protect the nish from scratches.

3.

Carefully tilt the oven onto its LEFT SIDE

ONLY (or CONTROL SIDE UP)

NOTE: Turning the unit onto its right side will

damage the control panel.

4.

Avoid sudden drops.

CAUTION

NEVER lay oven with the control side down, this will damage the controls.

THE OVEN WEIGHS 520 LBS (238KG). FOR SAFE HANDLING, INSTALLER SHOULD
OBTAIN HELP AS NEEDED, OR EMPLOY APPROPRIATE MATERIALS HANDLING
EQUIPMENT (SUCH AS A FORKLIFT, DOLLY, OR PALLET JACK) TO REMOVE THE UNIT
FROM THE SKID AND MOVE IT TO THE PLACE OF INSTALLATION.

ANY STAND COUNTER OR OTHER DEVICE ON WHICH THE OVEN WILL BE LOCATED
MUST BE DESIGNED TO SUPPORT THE WEIGHT OF THE OVEN.

WARNING

INSTALLATION

The ovens are equipped for the voltage indicated on the nameplate mounted on the lower right side
panel of the oven. They will operate on alternating current (AC) only. A cord & plug is not provided.

Consult you local codes for proper plugs, receptacles, and wire specications.

For optimum performance have separate circuits breakers for each cavity.

DO NOT CONNECT TO DIRECT CURRENT (DC).

The installation of the electric oven should conform to the:

NATIONAL ELECTRIC CODE AND ALL LOCAL ELECTRIC CODES AND
ORDINANCES AND THE LOCAL ELECTRIC COMPANY RULES AND
REGULATIONS.

VENTILATION & CLEARANCES

Local codes prevail. These are the “authority having jurisdiction” as stated by the National Fire
Protection Association, Inc. in NFPA 96-Latest Edition. For further ventilation information see below.

A ventilation hood may be required to remove heat and cooking odors. The hood and HVAC
installation must meet local codes to gain approval by the authority having jurisdiction. Requirements
may vary throughout the country depending on the location by city, county
information from the authority having jurisdiction to determine the requirements for your installation.
Obtain information and review copies of codes or documents that will be used to inspect and approve
your installation. Your ventilation hood supplier and HVAC contractor should be contacted to provide

guidance.

27" Legs

The legs supplied with the unit must be installed.

Legs are available for both the single and double deck installations.

SINGLE: require 27” legs or stands
DOUBLE: require 6” legs or casters.

To install the legs, place some cardboard on the oor and gently tip the oven onto its-back or non­control side. Fasten all four legs to the oven’s corners using the sixteen 5/16” bolts provided in
the leg kit. Once legs securely in place, with assistance lift the unit upright, the adjustable feet can
adjusted to level the unit. A torpedo level placed on the oven rack will assist in leveling the unit.

These units may be placed on a curbed base.

CAUTION

CAREFULLY TILT OVEN ONTO ITS LEFT SIDE (CONTROL SIDE UP) WHEN INSTALLING
LEGS, FEET OR CASTERS. TURNING OVEN ONTO ITS RIGHT SIDE (CONTROL SIDE
DOWN) WILL DAMAGE THE CONTROL PANEL.

the top of the lower oven, and install
a 1” plastic electrical bushing. With
assistance, lift the top oven and place it in
place on top of the lower oven.

Connect the two ovens by installing
the strapping plates to both the left and
right sides of the ovens. Attach the

oven earthquake strap (not-supplied) to

the eye bolt (supplied) at the bottom right
rear corner of the top oven, and secure
the strap to the wall once the oven has

been carefully placed into position.

CAUTION

ANY STAND COUNTER OR OTHER
DEVICE ON WHICH THE OVEN WILL
BE LOCATED MUST BE DESIGNED
TO SUPPORT THE WEIGHT OF THE

EARTHQUAKE STRAPS

If the oven is to be installed with casters, it must be secured to the building structure. To do this,
attach an oven earthquake strap (not supplied) to the eye bolt (supplied) at the bottom right corner
of the oven. For stacked ovens, attach the strap to the eye bolt of the uppermost oven. Connect
the earthquake strap to the wall or other structure per instructions supplied with the strap.

DRAIN CONNECTION

Attach drain plumbing to the ¾” NPTM oven drain tting located at the lower rear right hand corner
of the oven.

Drains need to have a vent pipe attached. Typical venting is accommodated by using a “T” off
the drain pipe with an 8” to 10” open pipe in the top part of the “T”. for stacking, the drains can be
manifolded together with only the top drain vented.

WATER CONNECTION

It is vital that the water supply line be thoroughly ushed with clean water before being connected
to the oven’s water manifold.

After your water has been tested and meets the minimum requirements (see water requirements).
Connect water supply to 3/8” NPTM tting located at right rear corner of the oven. Once the water
manifold and water supply are connected to the oven turn the oven ON and press the 1-shot steam
button for 1 minute to remove the air and any impurities from the system.

The water must continuously be within the specications (for this application) while this unit is in service.
Periodic testing may be needed to verify any changes in water conditions.

- IMPORTANT -

IF A SINGLE POWER SOURCE IS TO BE CONNECTED TO BOTH OVENS, REMOVE THE
CONTROL SIDE PANELS AND RUN THE INTERCONNECTION WIRES THROUGH THE 1”
PLASTIC ELECTRICAL BUSHING RUNNING BETWEEN THE TWO OVENS.

The electrical service entrance is provided by several knockouts in the top right rear corner of each
oven. The 208/240 volt oven is a dual voltage oven and is shipped from the factory ready to run on
either voltage without modication

Supply wire size must be large enough to carry the amperage load for the number of ovens being
installed. Line current information for individual ovens can be found on the oven DAT

Follow the ELECTRICAL SPECIFICATIONS (in the front of the manual) as a guide to select proper

wire sizes.

PHASE CONVERSION

The ECSF 208V / 240V ovens are shipped
from the factory wired for either single-phase or
three-phase, per the customer’s specications
on their order. Factory settings for Voltage and
Phase can be veried on the unit’s data plate
afxed to oven exterior.

If the phase requires modication, it can be
accomplished by rearranging the element wires
at the service entrance terminal block. Correct
connections are shown Below.

The ECSF 480V ovens are three phase only.
