M-WRG-II DVU-E-…, M-WRG-II DVU-R-… Fitting the valve body
- Before installing the design valve, pull the glass front plate (item 1 in Fig. 4) away from the valve body (item 2 in Fig. 4).
The design valve can be used as a supply air or exhaust air valve and may be used directly in a DN 100 ventilation pipe.
- To do this, press the valve body (item 1 in Fig. 1) into the ventilation pipe (item 2 in Fig. 1), turning it clockwise slightly at the same time.
Removing the valve body
- Pull the valve body (item 1 in Fig. 2) out of the ventilation pipe (item 2 in Fig. 2), turning it clockwise slightly at the same time.
Fitting and removing the glass front plate
We recommend that you measure the air volume flow rate with the glass front
plate fitted.
- To do this, unscrew the wing nut (item 1 in Fig. 3) slightly.
- Now press the glass front plate (item 1 in Fig. 4) with the springs into the valve cone (item 4 in Fig. 4) until you hear it click into place.
- To remove, simply pull the glass front plate away from the valve cone (see Fig. 4).
Regulating the air flow
- Turn the glass front plate (item 1 in Fig. 4) anti-clockwise to increase the air volume flow rate.
- Turn the glass front plate (item 1 in Fig. 4) clockwise to reduce the volume flow rate.
We recommend that you use a suitable measuring device (capture hood) to measure the air volume flow rate.
- After adjusting precisely, remove the glass front plate and fix the valve cone in this position using the wing nut (item 1 in Fig. 3).
- Then refit the glass front plate by pressing it back into the valve cone (see Fig. 4).
Minimum distance between design valves and the wall and ceiling
— Minimum distance (A) for design valve with square front plate: 150 mm (see
Fig. 5)
— Minimum distance (A) for design valve with round front plate: 130 mm (see
Fig. 6)
NOTE
Increase these distances if possible if the design valve is to be used as a
supply air valve (acoustics).
