Intended use Technical description The Dust Reduction System 2 (DRS2) is intended for installation on the roof of towed vehicles such as caravans, camper trailers and horse floats. It is intended for vehicles with roof thicknesses of 30 mm to 65 mm. The product reduces dust ingress while driving by pressurising the vehicle with filtered air. Additionally it provides ventilation while stationary when air flow passes through a secondary air path.
Installation 2 Notes on installation ! CAUTION! Risk of injury Improper installation of the product can result in irreparable damage to the device and put the safety of the user at risk. A NOTICE! Damage hazard • Observe the structural engineering of the vehicle and seal off all openings made when installing the product. • Check whether the roof of the vehicle is able to support the weight of a person before climbing onto it. Ask the vehicle manufacturer about the permissible roof loads.

Installing the DRS2 There are two ways of installing the system: • Making a new opening (chapter “Making a new opening” on page 8). In this case the opening must be reinforced by an appropriate frame. • Using the existing roof hatch openings in the vehicle (chapter “Installing in an existing opening” on page 8). 7. Use battens to create a frame around the cutout made in the roof. 8. If needed, remove the insulation foam according to the width of your reinforcing battens. 9. Fit the reinforcing battens.
4. Position the top roof flange centrally within the opening and mark the two rear corners on the roof. A NOTICE! Damage hazard Overtightening of the screws can cause damage to the threads and lead to distortion of the product. To avoid compromised fastening use a hand torque wrench and observe the specified torque. 5. Remove the top roof flange and screw onto the product assembly in the four corners using the 10G x 34 mm screws and tighten to a torque of 1.5 Nm using a hand torque wrench. 8 6.

Operation a 2 Ventilation while driving Observe the following notes: • In extremely heavy or prolonged rain, a small amount of water is expected to reach the filter. • In that case no additional care or steps need to be taken. – Keep the filter in the filter holder for the water to evaporate. The product operates automatically from vehicle speeds of 25 km/h. The product is suitable for use in the rain. ➤Prior to travel ensure that the blocker plate is removed (fig. b, page 11).
1. To fit the blocker plate, open the interior ceiling cover by pulling on the edge marked “PULL HERE TO OPEN”. Maintenance 2. Remove blocker plate from the ceiling cover, which is held by magnetic strips. The time for the filter to reach full capacity can vary greatly based on the road conditions: 3. Insert the blocker plate upwards. 4. Close the interior ceiling cover by rotating the cover upwards and pushing gently until the magnets engage to hold the cover closed.
Changing the filter Cleaning debris inside of the DRS2 1. Depending on the discoloration, tap the filter lightly to remove excess dust. It can continue to be used for some more time. After a long period of time, the product may accumulate some dust and debris. d 1. Remove the debris from inside the filter and filter holder by following the steps in chapter “Inspecting the filter” on page 12. 2.
Cleaning the ventilation frame ! Cleaning the insect screen CAUTION! Health hazard • Not cleaning the ventilation frame may lead to the formation of harmful gases in the ventilation airflow. • Check the frame at least every 6 months or more frequently if travelling in very dusty conditions. • The check interval of the frame should match the one of the filter. ➤Often visually check the insect screen for dust, insects and debris and clean it if any are present.
