B.S. Service KA7500, User Instructions

- 16 -

• Wear protective gloves before 

proceeding with the installa-

tion.

•  Electric Connection:

Note! Verify the data label placed inside the appliance:

- If the symbol   appears on the plate, it means that 

no earth connection must be made on the appliance, 

therefore follow the instructions concerning insulation 

class II.

- If the symbol   DOES NOT appear on the plate, follow 

the instructions concerning insulation class I.

Insulation class II

- The appliance has been manufactured as a class II, 

therefore no earth cable is necessary.

The plug must be easily accessible after the instal-

lation of the appliance. If the appliance is equipped 

with power cord without plug, a suitably dimensioned 

omnipolar switch with 3 mm minimum opening be-

tween contacts must be fitted between the appliance 

and the electricity supply in compliance with the load 

and current regulations.

- The connection to the mains is carried out as follows:

BROWN = 

L

 line

BLUE = 

N

 neutral.

Insulation class I

This is a class I, appliance and must therefore be con-

nected to an effiecient earthing system.

- The appliance must be connected to the electricity 

supply as follows:

BROWN = 

L

 line

BLUE = 

N

 neutral

YELLOW/GREEN

=   earth.

The neutral wire must be connected to the terminal 

with the 

N 

symbol while the 

YELLOW/GREEN

, wire 

must be connected to the terminal by the earth 

symbol  .

When connecting the appliance to the electricity 

supply, make sure that the mains socket has an earth 

connection. After fitting the ducted cooker hood, make 

sure that the electrical plug is in a position where it 

can be accessed easily. If the appliance is connected 

directly to the electricity supply, an omnipolar switch 

with a minimum contact opening of 3 mm must be 

placed in between the two; its size must be suitable 

for the load required and it must comply with current 

legislation.

•  

The minimum distance between the support surfaces 

of the cooking pots on the cooker top and the lowest 

part of the cooker hood must be at least 

65 cm

. If a 

connection tube composed of two parts is used, the 

upper part must be placed outside the lower part. Do 

not connect the cooker hood exhaust to the same 

conductor used to circulate hot air or for evacuating 

fumes from other appliances generated by other 

than an electrical source. Before proceeding with the 

assembly operations, remove the anti-grease filter(s) 

(Fig.9) so that the unit is easier to handle.

- In the case of assembly of the appliance in the suction 

version prepare the hole for evacuation of the air.

•  

We recommend the use of an air exhaust tube which 

has the same diameter as the air exhaust outlet hole. 

If a pipe with a smaller diameter is used, the efficiency 

of the product may be reduced and its operation may 

become noisier.

•  Fixing to the wall:

Make hole 

A

 respecting the shown dimensions (Fig.2). 

Fix device to wall and align it horizontally with the 

cupboards. When the appliance has been adjusted, 

definitely fix the hood using the screws 

A

 (Fig.6). For 

the various installations use screws and screw anchors 

suited to the type of wall (e.g. reinforced concrete, 

plasterboard, etc.). If the screws and screw anchors are 

provided with the product, check that they are suitable 

for the type of wall on which the hood is to be fixed.

•  Fixing the decorative telescopic flue:

Arrange the electrical power supply within the dimen-

sions of the decorative flue. If your appliance is to be 

installed in the ducting version or in the version with 

external motor, prepare the air exhaust opening. Install 

the upper decorative flue's support bracket and fix it 

on the wall using the screws 

A

 (Fig.3) so it is in axis 

with your hood and respecting the distance from the 

ceiling shown in Fig.2. Fasten the lower bracket 

P

 with 

the screws 

I

 (Fig.5). Connect flange 

C

 to air extraction 

hole via an air extraction pipe (Fig.6). Insert upper 

decorative flue inside the lower decorative flue and 

rest them on top of the frame. Extract the upper flue 

up to the bracket and fix it with the screws 

B

 (Fig.7). 

To transform the hood from a ducting version into a 

filtering version, ask your dealer for the charcoal filters 

and follow the installation instructions.

•  Filtering version:

Install the hood and the two flues as described in the 

paragraph for installation of the hood in ducting ver-

sion. Connect air diverter 

M

 (not supplied) to bracket 

and fix it with screws 

I

 as shown in Fig.4. The active 

charcoal filters must be applied to the suction unit 

inside the hood, centring them in it and turning them 

90° until they snap into place (Fig.8).

 USE AND MAINTENANCE

• 

We recommend that the cooker hood is switched on 

before any food is cooked. We also recommend that 

the appliance is left running for 15 minutes after the 

food is cooked, in order to thoroughly eliminate all 

contaminated air. The effective performance of the 

cooker hood depends on constant maintenance; the 

anti-grease filter and the active carbon filter both 

require special attention.

•  The anti-grease filter

 is responsible retaining the 

grease particles suspended in the air, therefore it is 

subject to clogging with variable frequency according 

to the use of the appliance.

-  To prevent the danger of possible fires, at least every 2 

months one must wash the anti-grease filters by hand 

using non-abrasive neutral liquid detergents or in the 

dishwasher at low temperatures and on short cycles.

-  After a few washes, colour alterations may occur. This 

does not give the right to claim their replacement.

•  The active carbon filters

 are used to purify the air 

that is sent back into the room and its function is to 

mitigate the unpleasant odours produced by cooking.

-  The non-regenerable active carbon filters must be 

replaced at least every 4 months. The saturation of the 

active charcoal depends on the more or less prolonged
