We offer a ten-year warranty for Velco thermostat valves. The manufacturing date of the valve can be found on the thermostat, so it is not needed to keep the purchase receipt.

1. Remove the hatch from its hinges so that drilling can be done horizontally. The easiest way to drill is, for example, on a sturdy box outdoors. Mark the installation point of the valve on the hatch with a pencil. It is advisable to position the valve approximately 150 mm down from the top edge of the hatch. Drill a pilot hole through the hatch with a thin drill bit, approximately 5–8 mm in diameter.

2. Follow the pilot hole with a hole saw (diameter 105 mm). Drill halfway from the inside and then continue from the outside to keep the surfaces intact 3. Fit the counterpart into the hole and shorten it if necessary. Attach the counterpart to the inside of the hatch with two screws.

4. Turn the valve plate counterclockwise to remove it from the valve, and attach the valve to the interior surface of the wooden hatch with three screws. Ensure that the valve’s sealing ring fits tightly against the inner surface of the counterpart.

5. Twist the valve plate back into place until it clicks.

6. Reinstall the ventilation hatch. Adjust the valve according to the user manual and complete the installation with a window filter (see instructions on the reverse side).

Velco filters are made from high-quality 3M Filtrete filter material. The filter’s effectiveness is based on its electrostatic charge, which attracts impurities like a magnet and traps them in the filter’s fiber structure. According to research by VTT, this exceptionally effective filter captures 100% of pollen and blocks a significant portion of ultra-fine particles that are highly harmful to health (VTT Research Report VTT-V88671-14).

1. Measure the size of the window opening. Ensure that the frame is dry and clean so that the tape adheres well.

2. Cut a piece of filter fabric to the appropriate size. If necessary, multiple pieces of filter fabric can be joined together by taping them tightly.

3. Attach double-sided tape to the edges of the insect screen or the window frame. Press the tape carefully to ensure it adheres well.

4. Remove the protective backing from the tape and attach the filter fabric by rolling it from the bottom to the top.

VALVE ADJUSTMENT INSTRUCTIONS In Velco valves, there is a self-contained thermostat that adjusts the valve opening according to the outdoor temperature. Upon delivery, the valve is in the factory default setting. In the factory default setting, the valve disc is fully open at an outdoor temperature of +10 °C and closes as the temperature drops to -5 °C. To ensure continuous ventilation, adjust the plate during installation to prevent it from fully closing when the temperature falls below -5 °C.

1. The plate is in the factory default setting when you hear a click while turning it.

2. When the plate clicks, turn the plate at least half a turn counterclockwise to open it.

3. After turning the plate half a turn, the valve will not close as the temperature decreases but will remain slightly open by approximately 2mm.

NOTE: The minimum valve opening can be adjusted as needed. For instance, in a building without mechanical exhaust ventilation, it is recommended to turn the valve disc one full rotation counterclockwise from the click position.
