We provide a ten-year warranty for Velco thermostatic valves. The manufacturing date of the valve can be found on the thermostat, so there is no need to keep the purchase receipt.

INSTALLATION INSTRUCTION 1. Choose a suitable installation location up close to the ceiling line. Mark the installation point and drill a marking hole through the wall with a long drill bit (approx. ø 6 mm).

2. Follow the marker hole with a hole saw ø 130 mm. Drill in half from the inside. Meet from the outside so that the wall surfaces remain unbroken.

3. Measure the wall thickness. Adjust the length of the telescopic tubes according to the thickness of the wall.

The pipes can be shortened if necessary. Fit the extension pipes FR-125 and the mounting plate AP-125 together. Apply installation glue AP-125 to the back side of the mounting plate. The installation glue should be spread as a strip along the entire length of the mounting plate to prevent leaks.

4. Fit the assembly tightly into the lead through and press until the installation glue hardens. Install the silencer ÄV-123/18 with the black edge first inside the pipes near the outer wall. The silencer can be shortened if necessary.

5. Place the filter frame wires (2 pcs) in to the holes on the back side of the valve. Set the louvre silencer between the wires. If necessary, the wires and louvre silencer can be shortened. Install the filter according to the instructions (see instructions on the reverse side). Check that the sealing ring is in the position indicated in the valve manual section 5.

6. Install the valve into the pipe. Rotate the valve body to seal the valve in place.

7. Fit the soundproofed grille TS-125 to the lead through on the outside wall side. It is recommended to attach the grille to the outer wall with an intstallation glue.

8. Finally, adjust the valve according to the adjustment instructions (see instructions on the reverse side).

-FILTER REPLACEMENT GUIDE A LWAYS U S E T H E V E L CO O R I G I N A L F I LT E R T O E N S U R E P R O P E RV E N T I L AT I O N S YS T E M F U N C T I O N A L I T Y The Velco VS-100 filter is made of high-quality Filtrete™ material developed by 3M. The Filtrete™ material uses exclusive 3-in-1 technology to pull in and trap unwanted particles, allowing cleaner air to flow through. Filtrete™ filters have an electrostatic charge that acts like a magnet to attract and capture microscopic allergens. Remember to change the filter regularly.

The filter must be changed when its surface is blackened, but at least once a year.

1. Take a grip from the valve body under the plate and carefully pull the valve out. Remove the dirty filter.

4. Thread the filter over the frame. Pull the filter over the sealing ring up to the valve body.

2. Ensure that the O-sealing ring is in the position indicated in the image.

5. Push the excess filter fabric remaining above the valve into the gaps between the frame wires. Make sure the sealing ring is in place under the filter.

3. Turn the filter inside out so that its seams are on the inside.

6. Place the valve back into position.

Rotate the valve within the passage pipe to ensure a proper seal.

-VALVE ADJUSTMENT INSTRUCTIONS I T I S I M P O R TA N T T O A D J U S T T H E VA LV E ACCO R D I N G T O T H E I N S T R U C T I O N B E L OW T O E N S U R E CO N T I N U O U S V E N T I L AT I O N !

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.

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.

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.
