Installation

The mounting plate is designed exclusively for the thermally insulated Maico MT-R125 thermal duct (hereafter MT ducts).

For mounting on wall:

Maintain an incline of 1 to 2 % towards the exterior wall.

  1. To protect against dust or plaster during the construction phase until the unit is installed, tape the MT ducts with the sealing foils supplied.
  2. Using the mounting plate, mark the position of the drill holes and then drill the holes.

The mounting plate can be used as a drilling template.

  1. Drill 180 mm core drill hole.
  2. For the opening(s) not required, straighten the tabs on the mounting plate, insert the MT ducts and fix them with the supplied screws.

  1. Fasten the mounting plate.
  4. Fix the MT ducts in the wall with mounting foam.

The recesses on the mounting plate are used to fill the cavity between the masonry and MT ducts with non-pressing construction foam using a foam gun.

  1. On the outer façade, adjust the duct length to the intended external wall coverings.
  2. Inside, affix the supplied sealing foils on the duct openings to prevent contamination during the construction phase.
  3. Before connecting the WS 120 Trio, remove the sealing foils from the MT ducts.
  4. Push the WS 120 Trio ventilation unit onto the two MT ducts.
  5. Fix the WS 120 Trio ventilation unit to the wall or ceiling → WS 120 Trio installation, commissioning and maintenance instructions.
  6. Remove the outer foils before fitting the external covers.
