INSTALLATION: 1) CREATING A HOLE: When drilling a hole, the distance from the ceiling must be at least 15cm. When drilling a hole, avoid hitting water pipes and electrical cables. The borehole must have a downward slope facing the outer wall. 2) INSTALLATION OF THE EXTERNAL PART: To install the outdoor grill, air duct must be pulled out in two parts. Mount the outdoor grille with the air duct on the wall from the outside. The grille needs to be fixed using an adhesive for outdoor use. Use a sealant where it's necessary. 3) INSTALLATION OF THE INTERNAL PART: To install the inner part, it is necessary to remove the diffuser from the air duct. Secure the air duct to the wall with four screws (Screws not included). Then refit the diffuser in the air duct. Set the required flow rate by rotating the diffuser front cover. through the wall air vent insulated sound passive fresh air intake vent fresh air exchanger for basement erv ventilation unit fresh air intake vent with damper thru wall vent
