VELCO FIX-80
REPLACEMENT VENTILATION SOLUTION FOR THE STRING VALVE
PACKAGING INCLUDES:
VT-80 thermostat-controlled valve
S-80 filter and structure wires
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 old valve. Ensure that the cover plate fits well into the hole. If the diameter of the hole is approx. 80 mm, the cover plate may not be necessary.
2. The installation glue should be spread in a continuous line along the entire length of the cover plate to prevent leaks.
3. Fit and secure the pipe into the lead through. The pipe can be easily shortened if necessary.
4. 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).
5. Install the valve onto the pipe. Rotate the valve body in the pipe to ensure a tight seal in place.
6. 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 PROPERVENTILATION 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. 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.
2. Ensure that the O-sealing ring is in the position indicated in the image.
3. Turn the filter inside out so that its seams are on the inside.
4. Thread the filter over the frame. Pull the filter over the sealing ring up to the valve body.
5. Push the excess filter fabric remaining above the valve into the gaps between the frame wires.
6. Place the valve back into position. Rotate the valve within the passage pipe to ensure a proper seal.
-VALVE ADJUSTMENT INSTRUCTIONS
IT IS IMPORTANT TO ADJUST THE VALVE ACCORDING TO THE INSTRUCTION BELOW TO ENSURE CONTINUOUS VENTILATION!
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.
