Frequently Asked Questions - MT-100 CATA

How to install the MT-100 fan in a duct?

Place the extractor between the suction and discharge points, respecting the direction of the arrows. Use hose clamps to secure the unit to rigid or flexible 100 mm pipes.

What is the maximum distance between suction and discharge?

The distance must not exceed 3 metres to ensure optimal operation.

What type of electrical cable should be used for connection?

Use a rigid two-conductor cable with a minimum cross-section of 1 mm². As the unit is double insulated, earthing is not required.

How to connect the fan electrically?

Unscrew the cover screw, remove it, then pierce the covers (C) to pass the cables. Connect the wires to the terminals of the terminal block (D) and fix it between the lugs (E). Replace the covers and screw them back on.

Does the fan require a specific switch?

Yes, an all-pole switch with a contact gap of at least 3 mm must be provided in the installation.

How to maintain the extraction fan?

Clean the blades and housing regularly with a damp cloth. Disconnect the unit before any maintenance.

Can the fan be installed outdoors?

This model is designed for indoor installation, in an air duct. It is not intended for direct exposure to weather.

What should I do if the fan is noisy?

Check that the hose clamps are properly fastened and that the duct is rigid. Abnormal noise may be due to an imbalance of the blades or an obstruction.

What diameters are available for this model?

The MT-100 is designed for a 100 mm duct. There is also a model MT-125 for a 125 mm duct.

How to disassemble the fan to access the connections?

Loosen screw (A) and remove cover (B). Covers (C) provide access to the connecting terminal block (D). Follow the reverse steps for reassembly.

INSTALLATION IN THE PIPING

For installation of the extractor in the air conduit piping, an opening (A) has to be made in the piping where there is the outlet for the extractor connection cables.

The opening must be long enough so that there is no interference with the cables emerging.

The width of the opening will be equal to or greater than the diameter of the drilling cover trim.

To fix the piping to the extractor, use the clamp flanges (C).

A) This tubular extractor is designed to be installed in a flexible or rigid conduit of 100mm . diameter for the MT-100 and 125mm diameter for the MT-125.
B) The distance between the intake and exhaust openings should not be more than 3m .
C) The extractor (C) is placed between points A and B (intake and exhaust) and fixed to the conduits by clamps that hold it securely in position.
D) It should be placed so that the arrows indicating the direction of the air flow coincide with the direction of intake and exhaust.

MT-100 AND MT-125 WITH SUPPORT BRACKET

The extractor (C) is placed between points A and B (intake and exhaust) and fixed in position using the plugs and screws provided.

The extractor unit should be connected to a single phase supply network at the voltage and frequency indicated on the extractor characteristics plate.

The electrical installation must be fitted with a single-pole switch with a distance between contacts of at least 3mm

The unit should be connected to the power supply network before being installed in the conduit (MT-100 and MT-125).

1) Loosen the screw (A) and remove the cover (B).
2) Perforate the plug (C) and thread the power cables through the hole.
3) Connect the power cables to the terminals for the connection strip (D) and, once connected fix it firmly between the pivots (E).
4) Insert the plug (C) in the hole between the housing (F) and the cover (B).
5) Replace the cover (B) and fix it in place using the screw (A).

The appliance must be permanently connected to a fixed installation of tubing and power supply cable. (Rigid cable with two conductors of at least 1mm^2 section. It does not require an earth connection as the unit has double insulation).
