The Wolf Electric Cooktops require a separate, grounded three-wire service with their own circuit breaker. These

appliances must be installed in accordance with National Electrical Codes, as well as all state, municipal and local

codes. The correct voltage, frequency and amperage must be supplied to the appliance from a dedicated, grounded

circuit which is protected by a properly sized circuit breaker or time delay fuse. The proper voltage, frequency and

amperage ratings are listed on the product rating plate.

Domestic cooktops are provided with a 48” (1219 mm) conduit consisting of two insulated hot lead conductors (cop-

per) and one insulated ground conductor (copper).

• APPLIANCE MUST BE PROPERLY GROUNDED AT ALL TIMES WHEN ELECTRICAL POWER IS APPLIED.

• DO NOT GROUND APPLIANCE WITH NEUTRAL (WHITE) HOUSE SUPPLY WIRE. A SEPARATE GROUND

WIRE MUST BE UTILIZED.

• IF ALUMINUM HOUSE SUPPLY WIRING IS UTILIZED, SPLICE APPLIANCE COPPER WIRE TO ALUMINUM

HOUSE WIRING USING SPECIAL CONNECTORS DESIGNED AND CERTIFIED FOR JOINING COPPER AND

ALUMINUM. FOLLOW CONNECTOR MANUFACTURES RECOMMENDED PROCEDURE CAREFULLY.

IMPROPER CONNECTION CAN RESULT IN A FIRE HAZARD.

SITE PREPARATION

COOKTOPS ARE INTENDED FOR INDOOR USE

ONLY.

TO ELIMINATE RISK OF BURNS OR FIRE BY REACHING OVER HEATED SURFACE UNITS, CABINET STOR-

AGE SPACE LOCATED ABOVE UNITS SHOULD BE AVOIDED. IF CABINET STORAGE IS TO BE PROVIDED,

THE RISK CAN BE REDUCED BY INSTALLING A RANGE HOOD THAT PROTECTS HORIZONTALLY A MINI-

MUM OF 5'' (127MM) BEYOND BOTTOM OF CABINETS.

For electrical installation attach the conductors to the

residence wiring in accordance with provincial, munici-

pal and local codes.

Multiple Cooktop Installations

If the Framed Electric Cooktop is to be used with any

combination of additional cooktop units or modules with

a filler strip, the cut-out width is calculated by adding the

corresponding units’ cut-out dimensions plus 1-1/4”

(32mm) for each additional unit (See Figure 2-3).

NOTES:• For Model CT15E, the cut-out width should be

increased from 13-3/8” (340mm) to 14” (356mm)when installed with multiple units.

• When multiple units are installed side by side, eachunit must have its own separate recommendedelectrical circuit.

• It is recommended that you operate the WolfElectric cooktop with either a Wolf cooktop ventila-tion hood, downdraft system or Pro ventilation hood.

When two or more modules are installed together, an

integrated module filler strip (IFILLER/S) is recommend-

ed. If a 30” (762mm) downdraft ventilation system is

also installed, an integrated module support for down-

draft ventilation (ISUPPORT) is also required. Contact your Wolf dealer for information on these accessory compo-

nents.

NOTE: Unframed electric cooktops Models CT30EU and CT36EU are not designed to be installed in combinationwith other cooktop units.

Ventilation Options

NOTE: It is recommended that you operate the Wolf Electric cooktop with either a Wolf cooktop ventilation hood,downdraft system or Pro ventilation hood. Contact your Wolf dealer for details.

The following is a list of ventilation units that can be used with the Electric Cooktops:

(see Figure 3-13).

NOTES:• The timer can be available to use in Idle, Showroom

and Operational Modes.• The timer can be set in minutes only.• The maximum minutes allowed is “99”.

Upon activation the timer display will display “01” (one

minute).

The unit will increment/decrement with the touch of the

''-'' / ''+'' Keys, one count every .5 seconds.

If the ''-'' or the ''+'' Key is held down for more the 3

intervals continuously and the count is divisible by 5, the

display will increment/decrement at a rate of 5 count per

every .5 seconds.

Likewise, if the ''-'' or the ''+'' Key is held down for more

than 3 intervals and the count is divisible by 10, the rate

of change will become 10 count per interval (i.e. 0, 1, 2,

3, 4, 5, 10, 15, 20, 30, 40, 50, …).

The timer is paused while entering the time and will start

3 seconds after the last change in value. Editing a run-

ning timer causes the seconds to be reset so that the

displayed time is what will be counted down. As a

result, if the minute time is counting down seconds, the

''-'' Key will stop the timer without an alarm.

Countdown: When the timer reaches 1 minute during

countdown the display will then switch to read 59, 58, ...

until 0 seconds is reached.

9. Refer to the Error Code Table on page 5- , for specific error code definition.

Page 34



Error Mode

Error codes are organized in a priority-based scheme which allows for different behavior based on the priority of the

error.

There are three priority levels, defined as follows:

Priority 1: Priority 1 errors are considered safety related or of such catastrophic scope that they control is considered

inoperable. These errors will continuously be displayed to the end user, indicating that a service call is required. No

user functions will be allowed, and any active functions will be cancelled upon generation of the priority 1 error. The

error can be canceled, but will re-generate if the condition which caused the error still exists.

Priority 2: Priority 2 errors will be displayed to the user only during an active cooking mode, or upon an attempt by

the user to enter a cooking mode. The criteria for these error is that they are likely to limit the proper functionality of

the system and would normally cause some customer dissatisfaction. These errors can be cancelled ([CLEAR] key

on keyboard) and will not be displayed again until the user again attempts to start a mode. Any active function on the

hob for which the error has scope will be cancelled upon generation of the priority 2 error. Errors with system scope

will apply to all hobs; errors with hob scope will apply only to the appropriate hob unless otherwise noted.

Priority 3: Priority 3 errors are defined as errors which could cause some possible or conditionally impaired function-

ality, most likely to be never noticed by the end user. These errors, although logged internally, will never be displayed

to the end user.

Error Clearing

If an error is corrected, the user or service technician may clear the error using the [CLEAR] key on the cooktop.
