COMMISSIONING 

Commissioning must be carried out in accordance with these instructions, and 
must be conducted by designated, qualified and competent personnel. 

Maximum Temperature 

The  maximum  blend  temperature  obtainable  by  the  user  should  be  limited,  to 
prevent accidental selection of a temperature that is too hot. 
The VADO-PRO-100P is fully performance tested, and the maximum temperature is 
preset to 41

  under ideal installation conditions at the factory. Site conditions and 

personal  preference  may  dictate  that  the  maximum  temperature  has  to  be  reset 
following installation. 
Adjust  the  mixed  water  temperature  in  accordance  with  table  2,  the  method  of 
adjustment is covered in this COMMISSIONING section.

Mixed water temperature 

 

Washbasin

41 max 

Maximum Temperature Setting: 

Make  sure  that  an  adequate  supply  of  hot  water  is  available  at  the  hot  inlet  of  the 
Thermostatic mixing valve. 
The minimum temperature of the hot water must be at least 10

  above the desired 

blend, however during resetting this should be close to the typical storage maximum 
to offset the possibility of any blend shift due to fluctuating supply temperatures. 
Make sure that both inlet isolating valve are fully open. 
Temperatures  should  always  be  measured  using  a  thermometer  with  proven 
accuracy. 
1.

 

Use the 2 mm Allen key (supplied) to loosen the grub screw in the lever. 

2.

 

Move the lever to full hot, note its position and remove the lever. 

3.

 

Let the water run until the temperature stabilizes. 

4.

 

Insert  the  2  mm  Allen  key  into  the  grub  screw  in  the  centre  of  the  head 
assembly. 

5.

 

Rotate  the  grub  screw  as  necessary  until  the  required  maximum  blend 
temperature  is  achieved.  Rotate  the  grub  screw  anticlockwise  to  increase  the 
temperature or clockwise to decrease the temperature. 

6.

 

Refit the lever in its original position. If required the lever can be fitted in any 
position  that  allows  unobstructed  movement  of  the  lever  over  its  operating 
range. 

7.

 

Move the lever to the off position. 

8.

 

Use the 2 mm Allen key to tighten the grub screw.

accuracy)
