found, note this on the bill of lading (all copies) prior to signing.

If damage is found when the equipment is opened, immediately call the delivering truck line and follow up
the call with a written report indicating concealed damage to your shipment. Ask for an immediate
inspection of your concealed damage item. Packaging material MUST be retained to show the inspector
from the truck line.

Remove all packing from the interior and exterior of the oven.

Location and Clearance

The oven must be mounted on a level surface capable of supporting the fully loaded oven. Refer to Chart
1 for oven weight.

Adequate clearance must be provided around the oven for safety, proper operation and ventilation. Refer
to Chart 1 for required minimum clearances. Note that these are minimum clearances. If the oven is to
be permanently mounted near other immovable objects additional clearance must be provided for
connection and service of the oven on both sides.

All ventilation slots must be kept free from obstruction.

Extraction

Extraction is not a specific requirement for this type of appliance. Certain conditions, e.g./ installation in a
confined space, temperature controlled environment, continuous use or high volume production cooking
may require the need for extra ventilation or extraction. Consult your local ventilation/extraction air
conditioning company.

Wiring

Electrocution, equipment failure or property damage could result if an unlicensed
electrician performs the electrical installation. Ensure that a licensed electrician
perform the electrical installation.

Failure to restrain the oven when permanently connected could allow it to
move, possibly resulting in electrical shock.

Attach an ANSI Z21.69A compliant restraining
device (such as BKI part number FT0279)
according to the instructions provided by the
restraining device manufacturer in the location
shown at right.

General Guidelines

• In the absence of local codes refer to the latest edition of one of the following:

• National Electrical Code, ANSI/NFPA 70-20XX (USA) which can be obtained from:

The National Fire Protection Association
Batterymarch Park
Quincy, MA 02269

• I.E.E. Wiring Regulations (Europe)

• Verify that the power supply conforms to the electrical rating listed on the oven data plate.

• Ensure that the appliance is grounded (earthed).

Guidelines for European Appliances

Note: - A method of disconnection from the main supply having a contact separation of least 3mm in

all poles must be incorporated in the fixed wiring.

• It is recommended that an R.C.D. with a 30ma trip and contact rating to suit the appliance current
be installed adjacent to the appliance.

• Type C/ 3 circuit breakers or appropriate rated fuses are recommended for installation at the
supply end.

Note: - surge currents are present when this appliance is switched on from cold.

• Industrial plugs and sockets must comply with BS 4343/EN60309 (IEC309.2/CEE17).

Supply Cable Connection

• It is recommended that the power supply cable shall be an oil resistance sheathed flexible cable
to BS 6007 (code designation HO7 RN-F).

• It is required that the power supply cable connection to the appliance terminal block, the earth
conductor is to be made at least 50mm longer than the length of the live (L) and neutral (N)
conductors so that if the supply cable is strained the earth conductor is the last to become
disconnected.

• To gain access to the control panel and mains block connection, remove the 4-side panel
securing screws on the drive side of the oven.

• The mains block is sited toward the bottom right hand side of the control box. Cable entry is
provided through the base of the oven.

• Refer to the mains wiring diagram for correct connection.

Operating

Please read the operating instructions thoroughly and ensure all packaging has been removed before
switching main power ‘On’.

IMPORTANT: Ensure that whoever is operating this appliance is fully conversant with its working and is
made aware of the dangers of incorrect operation.

Safety Cut-Out

For added safety all COq ovens have a built in thermal cut-out to protect against over-heating through
component failure or incorrect use. If for any reason the thermal cut-out operates, the oven will
automatically shut down and should be switched ‘Off’, disconnected from the mains and allowed to cool.

NOTE: - The thermal cut-out will not re-set automatically.

The oven must not be re-used until a qualified electrician or BKI service agent has checked it.

Maintenance

Failure to comply with the maintenance below could result in a serious accident or
equipment damage.

Failure to remove power from this unit before performing maintenance may cause
severe electrical shock. This unit may have more than one disconnect switch.

Scheduled Maintenance

Oven Cleaning (Daily)

Cleaning is not only necessary for sanitary reasons, but will increase sales appeal and maximize
