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.
NOTE: Installation of Wolf Electric Cooktop must meet the following location requirements. All dimensions listed areminimum requirements for safe operation.
Location In Countertop: (Refer to Figure 2-2):
A. Minimum flat counter top surface. Must be equal to or greater than cooktop width.
B. Minimum 1” (25mm) wide clearance from the cooktop side edge to any combustible surface up to 18” (457mm)
above the cooktop (noted by shaded area).
FAILURE TO LOCATE THE COOKTOP WITHOUT
PROPER CLEARANCES WILL RESULT IN A FIRE
HAZARD.

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.

Timer Operation:
To start the timer: Press and release the timer ''+'' Key
(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.
When the timer counts down to 0 sec. the unit will beep
once every 5 sec. and the display will flash “00” until
CLEAR Key is pressed to stop the beep and clear the

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.
