DESCRIPTION 

The VADO-PRO-100P is a lever operated sequential mixing valve for basins. It uses 

proven  thermostatic  technology  for  temperature  control.  A  single  lever  provides 

sequential  operation  from  OFF  through  COLD  and  WARM  to  a  maximum  blend 

temperature preset at 41 , which can be adjusted if required. 

The VADO-PRO-100P is designed for single or two hole basins. 

The supply connections are via flexible inlet tails and  check valve assemblies that 

incorporate check valves and filter. 

 

 

SAFETY: WARNINGS

 

The VADO-PRO-100P is precision-engineered  and should  give  continued superior 

and safe performance, provided: 

 

1.

 

They are installed, commissioned, operated and maintained in accordance with 

the recommendations given in this Manual. 

2.

 

Periodic  attention  is  given,  as  necessary,  to  maintain  the  product  in  good 

functional order. 

 

                                                                                                                               

 

The function of a thermostatic mixing valve is to deliver water consistently at a safe 

temperature.  In  keeping  with  every  other  mechanism,  it  cannot  be  considered  as 

being  functionally  infallible  and  as  such,  cannot  totally  replace  the  vigilance  of
