I. INSTRUCTIONS FOR THE
GB
INSTALLER
Professionally qualified persons should carry out the installa-
tion in accordance with current local standards and regulations.
The following should be referred to in particular:
•
UNI-CIG 8723 – Safety regulations for kitchen gas appli-
ances.
•
ITALIAN LAW No. 46 of 5 MARCH 1990 – Safety require-
ments for electric and gas systems
•
LOCAL HYGIENE AND HEALTH REGULATIONS.
1. GENERAL
Two versions are supplied.
1. With built-in electric fan, the models:
-KFV with electric fan 220-240 V (1) 50-60 Hz, type 9/9, 550W.
-KLWV with electric fan 220-240 V (1) 50-60 Hz, "lowered" type
9/9, 420W.
-KLCV with electric fan 220-240 V (1) 50-60 Hz, type 7/7, 300W.
All the models with built-in electric fan are fitted with an "auto-
matic" fan speed control, which adjusts the extracted air flow
according to the percentage of humidity measured in the
environment by a sensor placed in the suction flow.
2. Without built-in electric fan, the models:
-KF
-KLW
-KLC
The models without built-in electric fan do not have any speed
control.
Only the models for the ovens (KF-KFV-KLW-KLWV) are fitted
with a labyrinth filter.
2. POSITIONING AND MOUNTING
2A - KF-KFV models for convection steamers.
The hood is mounted directly by "resting" it on top of the oven.
Before finally positioning the hood, remove the hinge cover to
be found on the right side of the top of the oven.
Fix the hood through the support "D", which should be secured
to the oven using the two screws "A" and to the hood using the
two screws "B" (fig. 1-2).
The screw "C" is applied to the hole previously used for fixing
the hinge cover.
2B - KLW-KLWV models for "Length Wise" convection steam-
ers.
The hood is mounted directly by "resting" it on top of the oven (fig.
3-4).
Remove the two rear screws to be found on the oven cover and
fix the hood to the oven using the same screws.
Two trims are provided (just one is used, the right one for oven
with hinge on right, the left one for oven with hinge on left), which
serve to cover the gap and should be positioned under the
filters.
2C - KLC-KLCV models for dishwasher with hood.
The hood should be wall mounted (the wall must be load-
bearing), using the four reversible brackets provided.
These brackets allow the necessary small adjustments for
levelling and for perfect connection to the dishwasher.
Refer to the assembly diagram shown in fig. 5-6, paying
particular attention to the brackets, which should be positioned
according to the type of machine being used (dishwashers with
capacities of 900 and 1200 dishes/hour).
With the models for ovens (KF-KFV-KLW-KLWV), the recom-
mended minimum size for the flue pipe is 300x300 mm.
With the models for dishwashers (KLC-KLCV), the recom-
mended minimum size for the flue pipe is 250x250 mm.
It is also recommended that a damper always be installed
immediately above the hood so that the air flow can be correctly
adjusted (thereby avoiding over-absorption by the extractor).
3. ELECTRICAL CONNECTION
The appliance should be connected to the mains supply by a
qualified electrician in accordance with current regulations.
Make sure that the supply voltage and frequency correspond to
the data given on the electric fan rating plate.
Carry out the electrical connection (for models with built-in
electric fan only) from the omnipolar (pole-independent) switch
powering the appliance (to be installed by the user) to the
relative EE junction box, using a flameproof cable with a mini-
mum cross section of 3x2.5 sq.mm, in compliance with the
wiring diagram.
The KLCV models for dishwashers are also fitted with a built-
in illuminated on-off switch on the front control panel.
4. STARTING UP
(hood model with electric fan)
•
When the omnipolar switch, which powers the appliance, is
put to "on" the electric fan is also powered at 80 V and the
indicator light inside the controller comes on (learning phase
lasting one minute).
• On the dishwasher hood, check that the switch-indicator light
located on the front control panel is on.
• If the humidity value measured by the controler falls within
operating parameters at the end of the 1
<80% RH), this value is stored and the indicator light goes out.
During the updating phase, the controller checks that the value
measured by the sensor is within + 6% RH (humidity increas-
ing) or - 6% RH (humidity decreasing) compared to the last
stored value, updating it in order to follow the normal climatic
trend.
• If the humidity increases by 1% compared to the last updated
value at any time, the controller increases the fan speed by 5%
for each RH degree (adjustment phase).
•
If the indicator light starts to blink after the 1
frequency of 60 times a minute), the appliance is in standby:
(a) start up of the system in a humidity-saturated or very dry
environment
(b) faulty sensor.
In these cases the electric fan continues to be powered at 80
V, while the controller continues to read the environmental
humidity values. When the measured value returns to within the
established parameters, the indicator light goes out and the
appliance enters into the normal operating phase.
If the indicator light continues to blink, this indicates that the
sensor is faulty and should be replaced.
•
The controller systematically checks the following param-
eters:
-phase
-voltage
-fan power factor (W)
-correct switching on of the TRIAC.
•
If one or more of the above-mentioned parameters is
abnormal for more than three consecutive times during this
check, the controller switches off the motor and the internal
indicator light blinks fast.
These parameters may be reset by putting the controller to
