The ball valve allows the flow circuit line to be divided between the 
collector  and  the  heat  accumulator.  As  required  by  safety 
regulations,   the   connection   between 
the collector and safety valve 
not interrupted in any of the b 
valve positions.

through the tank. 

The venting tank can hold up 
2.5 dl of air and has a bleed 
releasing the air. 

 

The  bleeder  valve  is

means  that  it  can  be  acce 
when  the  insulating  casing 
outlet  has  a  suitable  fitting 
attachment of a hose. 

The   frequency   and 
collected air can be used to 
leak tightness of the system 

Pressure gage

 

 

The pressure gage  with a  range from 0 to 
10 bar indicates the system pressure. 

Thermometer

 

 

The  thermometer  with  a  range  from  0  to  160ºC  constantly  indi- 
cates the medium temperature in the flow circuit. The temperature 
is recorded directly in the medium to minimize the reaction time. 

The  sensor  is  inserted  in  a  protective  pipe  so  that  it  can  be 
exchanged without having to empty the system. 

The ball valve allows the return line to be split between the collector and the heat accu- 
mulator. The special ball cock design provides various functions. If the handle is pointing 
in the direction of flow the system medium can circulate. An integrated check valve stops 

osite direction and also acts as a gravity brake. 

right closes the ball cock in the direction of  the medium 

tem part  (collector) to be filled and emptied  using the fill 

 

ndle 90º to the left closes the ball cock in the direction of 

dium  flow  and  allows  the  lower  system  part  (reservoir)  to 
e filled using the fill and drain cock. 

A male thread G 

3/4” is provided on the fill and drain cock 

for connecting a hose. Holes are provided in the handle of 

ball  valve  so  that  it  can  be  sealed  to  protect  against 

nintentional closing. 

 

WILO ST 25/6-3 circulation pump, solar version

 

 

This circulation pump, included as standard in the scope 
of  delivery  and  integrated  in  the  hydraulic  kit,  covers  a 
large delivery range. 
The  required  operating  point  can  be  preselected  using 
one of the three levels. 
A  defective  pump  can  be  replaced  without  having  to 
empty  the  system  using  the  stop  cocks  on  the  suction 

side (Setter Inline UN) and the pressure side (ball valve). 

 

SETTER Inline UN balancing valve

 

 

stment at the balancing valve allows the required delivery 

adapted to system requirements. The proven combination 

alve and flow indicator in one housing in the  hydraulic kit 

es  means  that  no  additional  measuring  components  are 

e SETTER Inline UN. Flow rate indication is constant, i.e. 

t can  be  immediately verified  by  means  via  the  flow  rate 

indicator  is  pre-calibrated  for  a  medium  viscosity  of  2.3 

his does away with the need for correction curves. 

nection  flange  on  the  outlet  side  is  directly  screwed  onto 

” pump connector fittings which means there are no seal 
for further adapter components. 

ctor ADG

 

 

The  connector  fitting  with  G 

3/4”  connecting  thread  for  the  expansion 

vessel is connected in series with the circulation pump. This arrangement 

prevents negative working pressure conditions in even critical systems and avoids reduc- 
tions in the working pressure, one of the main causes of early evaporation of the medium. 

Thermometer

 

 

The thermometer with a range from 0 to 160ºC constantly indicates the medium tempera- 
ture of the flow circuit. The temperature is recorded directly in the medium to minimize 
the reaction time. 
The sensor is inserted in a protective pipe so that it can be exchanged without having to  
empty the system.
