4.1 Starting up a new installation: 

(See illustration on page 10 for references) 
 

 

1. 

Check that all connections are joined correctly and  

2. 

ensure that the pump (12V) is disconnected  

3. 

Fully open valves V4 an V5, V1 must be closed 

4. 

Water (without anti-freeze) is filled via valve V2 until water reaches the expansion tank 

5. 

Shut valve V2 and add water to via valve V3 until the water reaches the expansion tank 

6. 

Check if there are any leakages and open V1, shut V3 and let the air out by the red handle. 

 

 
4.2 Testing pump and circulation  
 

1. 

Connect the pump (take care to use correct polarity!)  

2. 

If the sun does not shine a 12V battery may be used to run the pump the yellow remark below on this page. 

3. 

Check the flow gauge when the pump runs. Output should be at least 1 L/min 

4. 

If the flow is below this minimum there is probably air in the system. 

5. 

A power drill pump may be inserted between valves V3 and V2 (V1 must then be closed) to force circulation. 

6. 

The pump sucks from valve V3 and blows into valve V2 

7. 

Run for some minutes until there is no evidence of air bubbling in the expansion tank. 

8. 

Test the system again with the ordinary pump 

9. 

Add water if the liquid level in the expansion tank is below minimum 

10. 

If there is flow in the system proceed to 4.3 Otherwise go back to step 5 

 

 
4.3 Adding anti-freeze (for locations with risk of frost) 
 

1. 

4,5 L of water mixed with anti-freeze (fluid) is pumped in at valve V2  

2. 

An equivalent volume is let out at valve V3 

3. 

Watch the liquid level in the expansion tank 

4. 

If the level is below minimum add water. When doing this turn off the pump to avoid any sucking in of additio-
nal air. 

5. 

Do not fill the expansion tank to overflowing.  

 

4.4 Re-starting your SV30AWX 
 

If you have turned off the fluid based part of your SV30AWX for a period, it is necessary to re-start it.  
Whilst the equipment is already filled with liquid, this will normally cause no problem.  
Please follow the instructions below: 
 

• 

Check the liquid level in the expansion tank. Add water if it is below minimum 

• 

Connect the pump 

• 

If there is sunlight, the circulation will normally start 

• 

Otherwise follow the instructions given above in 4.2. step 5 

Note:  If a battery is used as starting aid, the regulator should be bypassed and a 12V battery  
connected direct to the pump. As long as you do this you may use the highest speed level on  
the pump - step 5. This will normally enable the pump to push all air out of the collector and 
tubing. When finished set back the speed level at 1 or 2. Be sure that the flow is 1 litre pr minute  
or more.
