Frequently Asked Questions - MT-125 CATA

How to install the MT-125 fan in a duct?

Place the extractor in a rigid or flexible duct of 125 mm. Secure it using clamping collars for complete immobilization. Ensure that the arrows indicating the air direction match the direction from suction to exhaust.

What is the maximum distance between suction and exhaust?

The distance between the suction opening and the exhaust opening must not exceed 3 meters.

How to electrically connect the MT-125?

Loosen the cover screw, remove it, pierce the covers to pass the cables. Connect the power cables to the terminal strip, place the terminal strip between the lugs, replace the covers and secure the main cover. The device must be permanently connected to a fixed installation with a rigid cable of minimum cross-section 1 mm².

Is an earth connection required for the MT-125?

No, the device has double insulation. Earth connection is not necessary.

How to clean the MT-125 extractor?

Disconnect the device. Clean the blades and housing with a damp cloth. Do not use abrasive products or solvents. Never immerse the device in water.

What to do if the extractor does not turn?

Check that the power supply is present (230 V). Check the connection at the terminal strip. Ensure that the all-pole switch is in the on position. If the problem persists, contact customer service.

Can I use a speed controller with the MT-125?

The MT-125 is a single-speed fan. Using a speed controller is not recommended and could damage the motor.

How to fix the extractor without clamps?

For the version with bracket, use wall plugs and screws to fix the extractor to the wall or ceiling, respecting the air direction.

The extractor is noisy, what to do?

Check that the device is properly fixed and that the clamps are tightened. Make sure the blades do not touch the housing. Regular cleaning can reduce noise. If the noise persists, the motor may be defective.

Operation and maintenance instructions

INSTALLATIE AAN BUIZEN

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 100 mm. diameter for the MT-100 and 125 mm diameter for the MT-125.
B) The distance between the intake and exhaust openings should not be more than 3 m.
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.

ELECTRICAL CONNECTION MT-100 AND MT-125 WITH SUPPORT BRACKET

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 3 mm.

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 fo 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 1 mm² section. It does not require an earth connection as the unit has double insulation).
