FOR A NEW WALL MOUNTING

PACKAGING INCLUDES:

VT-100 thermostat-controlled valve S-100 filter and structure wires

VR-100 wall pipe FR-125 extension pipe, 2 pcs

RE-97 silencer disc YG-100 outdoor grille. White

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. Mark the installation point and drill a pilot hole through the wall using a long drill bit.

2. Follow the pilot hole with a hole saw (approx. ø 105mm). Drill halfway from the inside, and meet the hole from the outside, in order to keep the wall surfaces intact.

3. Measure the thickness of the wall. Adjust the length of the telescopic pipes according to the wall thickness. If necessary, the pipes can be shortened. Install the wall pipe VR-100 and extension pipes FR-100 tightly into the lead through. Use glue if necessary.

4. Attach the wall pipe VR-100 to the wall using screws. When using the RE-97 sound damping disc, install it with the black edge facing inward into the pipes. Place the sound damping disc close to the exterior wall.

5. Turn the filter upside down so that its seams are on the inside.

6. Place the filter frame wires (2 pieces) into the holes at the back of the valve, opposite each other. If necessary, you can bend or shorten the wires. Install the filter according to the filter instructions (see instructions on the reverse side).

7. Install the valve into the pipe, ensuring that the sealing ring is in the position indicated by the instruction picture. Rotate the valve body within the pipe to secure the valve in place. Fit the external grille YG-100 into the lead through from the exterior wall side. It is recommended to attach the external grille to the exterior wall using installation glue.

8. Insert the valve into the pipe. Rotate the valve body slightly within the pipe to secure the valve in place. Adjust the valve according to the adjustment instructions (see instructions on the reverse side).

-FILTER REPLACEMENT GUIDE

ALWAYS USE THE VELCO ORIGINAL FILTER TO ENSURE PROPER VENTILATION SYSTEM FUNCTIONALITY

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.

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.

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

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 +20 °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.
