3. Using the Stove Guard
Safera Stove Guard observes the tem-
perature changes and the use of the
cooker. The Stove Guard automatically
gives an alarm and switches o the coo-
ker and the oven in a hazardous situati-
on based on temperature changes and
also if
• the cooker is left on for over 3 hours
without anyone using it,
• the cooker has been on for over 5
hours, or
• the oven has been on for over 12
hours without anyone using it.
3.1 Setting the Alarm Limit
To ensure safe and reliable operation,
you need to set the alarm limit to match
the location of the cooker in the kitchen.
The alarm limit may also be adjusted in
case of frequent false alarms. See Ins-
tallation manual for further information.
ѥWARNING
The Stove Guard controls the oven
only if the oven is connected to the
power control unit Ⓒ.
The cooker’s hot-hob indicators do
not work after the Stove Guard has
switched o the cooker. The hob may
still be hot.
⚐ATTENTION
The Stove Guard is designed to avoid
raising unnecessary alarms. This
means that it allows the temperature
to reach high levels during cooking
without raising an alarm.
It does not sound an alarm until it
looks like the situation may be dan-
gerous.
3.2 Other safety features
For safety reasons, the stove guard will
prevent the use of cooker and oven, if
• the sensor unit Ⓐis removed from
its original installation position:
place the sensor unit back on the
mounting bracket Ⓑ
• the batteries are empty: replace the
batteries (see chapter 4.3)
• if the sensor unit is Ⓐ faulty: see
chapter 5. Troubleshooting. Until
the fault is ixed, use of the cooker
is possible for three hours by remo-
ving the batteries from the sensor
unit Ⓐand the fuses from the coo-
ker for 10 seconds.
3.3 Cooker danger
This is a warning that the cooker is dan-
gerously hot, or when the cooker or
oven is left on for too long. An alarm is
sounded and the indicator light ❹las-
hes red. The Stove Guard switches o
the cooker and the oven in 15 seconds.
When you hear the alarm:
1. Check the situation calmly. If there is
no danger, you can prevent the coo-
ker power from being switched o
by pressing the OK button ❸during
the alarm and continuing to cook.
2. If you do not press the OK button ❸
during the alarm, the Stove Guard
will switch o the cooker and the
oven: after switch o a repetitive sig-
nal is sounded and the indicator light
❹blinks red for 15 minutes.
3. When there is no more danger, you
can return the power to the cooker
and oven by pressing the OK button
❸. First, turn the hob switches to the
zero position.
4. Ensure that the hazardous situation
will not reoccur.
ѧHINT
If the case of frequent false alarms,
you can raise the alarm limit, see 3.1.
Setting the Alarm Limit.
3.4 Water Leakage Detector
(optional)
Safera Stove Guard can be equipped
with up to four water leakage sensors.
When the sensors get wet for example
because water drips on them, the dete-
ctor will sound an alarm with far-spaced
signals and indicator light ❹blinks blue.
When you hear the water leakage alarm:
1. Reset the alarm by pressing the OK
button ❸.
2. Before continuing, make sure the
power supply for the cooker is turn-
ed o.
3. Find out what caused the alarm and
take care of the water leakage.
4. Clean and dry the sensor Ⓕ.
ѧHINT
If the sensor is left wet, the appliance
will give another alarm in 8 hours af-
ter signing o the previous one.

ditions. The warranty applies to the De-
fects (as deined in Section 6) covered
by the warranty, which are notiied to
Safera during the warranty period. This
limited warranty does not limit a consu-
mer’s right to claim the rights according
to the mandatory applicable consumer
protection legislation.
9.2 Start of the Warranty
Period
The warranty period starts from the date
of the irst purchase of the Product. In

ready to a new apartment, the date of
the purchase shall be deemed to be the
date of irst purchase of the apartment.
In case the Product is installed by the
end user, the end user shall inspect the
Product prior to the installation and wi-
thout delay inform the seller of the Pro-
duct about the defects or errors in the
Product or its delivery.
9.3 Warranty Period
The warranty period shall be twenty-four
(24) months.
9.3.1 Warranty to a Repaired
Product
Warranty for a Product that has been re-
paired or replaced shall be the original
warranty period of the Product which
was repaired or replaced.
In addition, Safera gives to the spare
parts used in the warranty repair of the
Product an additional three (3) months
warranty starting from handing over of
the warranty repair. Otherwise warranty
repair does not extend the original war-
ranty period.
9.4 Work Included in the
Warranty
Based on the warranty the Defects co-
vered by the warranty will be repaired
or the Product will be replaced (as Sa-
fera selects) without expense, provided

ranty claim during the warranty period.
The repair or replacement will be made
within a reasonable time during normal
working hours in Safera’s repair shop, in
a repair shop authorized by Safera or in
other place designated by Safera, such
as in the premises where the Product is
installed.
9.5 How to Act
For the warranty service, the end user
shall contact primarily the seller of the
Product. The end user may also contact
Safera or a repair shop authorized by
Safera. Information about the warranty
service is in the Product’s user manual
or on Safera’s website.
Safera, the seller of the Product or a
repair shop authorized by Safera (de-
pending on with whom the end user
is in contact) informs the end user of
how and when the warranty repair will
be performed. In case this has not been
informed to the end user within a reaso-
nable time, the Product shall be delive-
red to the nearest Safera’s repair shop
or a repair shop authorized by Safera.
The original parts which have been
replaced under the warranty shall be
Safera’s property and shall be delivered
to Safera.

Repair
Warranty is valid on condition that the
Product has a defect attributable to ma-
terial or manufacturing or it otherwise
does not substantially conform to its
written speciications (”Defect”) and

age conditions deemed normal and
it can be reproduced in such condi-
tions,
