Device Disassembly - M-system MSU-50 Mode D'emploi

ENGLISH
DESCRIPTION
The hood may be installed in the filtering or the ducting version. Filtering version (Fig. 1): The hood aspirates the
kitchen air saturated with fumes and odours, purifies it through the grease filters and charcoal filters and returns clean
air into the room. For constant efficiency, the charcoal filters must be replaced periodically. The charcoal filters are not
supplied. Ducting version (Fig. 2): The hood aspirates the kitchen air saturated with fumes and odours, passes it through
the grease filters and expels it to the outside through an outlet pipe. With this version the charcoal filters are not required.
Decide from the outset on the type of installation (filtering or ducting). For greater efficiency, we recommend you install
the hood in the ducting version (if possible).
INSTALLATION
ATTENTION: The appliance should be installed by a qualified operator.
INSTALLATION IN DUCTING VERSION:
1. Before fixing, the disposal duct for air evacuation to the outside must be installed. Use an disposal duct with:
– minimum indispensable length; – minimum possible bends (maximum angle of bend: 90°); – certified material (according
to the State); – an as smooth as possible inside. It is also advisable to avoid any drastic changes in pipe cross-section.
We recommend using a 150 mm diameter pipe. For air evacuation to the outside, follow all the other instructions given
on the "Warnings" sheet.
2. Prepare a suitable power supply. For the electrical connection, follow all the other instructions on the "Warnings"
sheet.
3. Cut a hole in the bottom of the pensile cupboard in order to settle the appliance (Fig. 3). The pensile cupboard
bottom must be 16 mm thick. Check that the fixing tabs (Fig. 4) to the wall unit are positioned at a height suited to the
thickness of the bottom of the wall unit. If this distance is less than the thickness, increase it by unscrewing the 2
corresponding screws inside the hood.
4. Insert the appliance in the hole (Fig. 3).
5. Tighten the 2 screws inside the appliance (Fig. 6) until it fits snug on the bottom of the wall unit. Do not tighten
the two screws strongly to maintain the two metallic clamps in the right position.
6. Connect the disposal duct to the air evacuation pipe of the hood. Use a flexible pipe and lock it to the air evacuation
pipe of the hood with a metal hose clamp (pipe and clamp are not provided). Make the electrical connections.
INSTALLATION IN FILTERING VERSION:
Proceed with installation, making reference to the instructions for the extraction version (see points 2, 3, 4, 5), and
then follow the instructions below.
Connect the hose to the hood air outlet so the air is conveyed to the top of the wall unit; secure the hose with a metal
clamp (hose and clamp are not provided). Make power connections.
Check whether the charcoal filter(or canister) is already installed; if not, assemble it as follows: open the metal panel
and remove the grease filter (Fig. 6); install the charcoal filter: rest the charcoal filter on the motor unit by making the
pins coincide; turn the charcoal filter until this is fast (Fig. 7).
Re-assemble the grease filter and close the metal panel.

DEVICE DISASSEMBLY

During the following operations always support the device.
Tighten the 2 screws inside the device (Fig. 5); moving the 2 small tongues toward the device inside using the right
carvings (Fig. 8); pull out the device from its side.
OPERATION
Depending on the model, the unit is equipped with the following controls:
Controls shown in Fig. 9:
A) Turns the lights off.
B) Turns the lights on.
C) Reduces the motor speed until reaching zero. If pressed for 2" when the Filter Alarm is active, the HOUR counter is
reset.
D) Drives the motor (calling the last speed used) and increases the speed until reaching maximum.
E) Activates/deactivates the sensor (AUTOMATIC or MANUAL mode). In Automatic mode the sensor is active and the
letter "A" appears on the display (L).
L) Display:
- signals the running speed
- signals Automatic mode by displaying the letter "A". When the motor speed is changed, the running speed is displayed
flashing 3 times, and then the letter "A" reappears.
- signals the filter alarm (with motor off) by displaying the central segment for 30".
