NOTE!
• Maximum wall thickness 430mm. Hole-punching Ø 105mm.
• Make sure to adjust the valve before use.
• Attach this operating manual to the apartment maintenance book.
• Remember to replace the air lter at least once a year, when the lter surface gets heavily polluted.
• Use the silencer only if necessary (if the wall with a valve is located directly on the street), since the
silencer reduces the ow of air.
• One supply valve must be installed on every 20 m² area (applies Ø100 mm size).
• Velco thermostat supply valves have a 10-year product warranty.
Placement
• As high as possible on the wall, however at least 10 cm below the ceiling.
• Above or in direct connection with a window and a radiator.
• Avoid installation in proximity to electric wiring and water pipes.
Installation
1. Use long drill to mark-up the installation spot.
2. Use Ø105 mm hole punch and drill from inside to outside so that the tube slopes very slightly downwards. (approx. 1 mm/100
mm.) In order to prevent damage to the wall surface drill halfway through from each side.
3. Fit the required number of extension tubes to extend through the wall and seal with sealing agent. Depending on the wall
thickness, an additional wall tube may be used. If necessary the tube can also be cut.
4. If necessary: insert the silencer in tube black side facing outwards.
5. Assembly the air lter by installing the frame wires (2 pieces) in the holes located at the back of the vent. The wires can be
shortened if necessary. Seal the vent holes and wires with glue in order to facilitate lter replacement in the future.
6. To assemble the air lter, turn the lter upside down so that the uffy side is facing out and thread it over the wires.
7. Screw the vent cover clockwise until a clicking sound is heard, then adjust the valve half a turn to the left. The tting of the
valve is now complete.
8. Fix the vent in place. The sealing ring holds the valve in place so no further sealing with glue is needed. The vent is now
installed.
9. When replacing the lter, just carefully pull the tube out.
