5.3 Filling solar heating
system
Note
No special safety measures are required when working with the diluted
glycol solution specified by the manufacturer. For more information about the
fluid, please contact the manufacturer.
Note
The filling procedure described in this manual is intended for the pump
system supplied by the supplier of the appliance. For any other system, you
should follow the procedure for that system.
Warning
To avoid contaminating the glycol, you should flush the solar heating system
through with water before filling.
5.3.1 Flushing with water
1. Connect a water supply to the filling point of the pump station.
2. Connect a drain hose to the drain point.
3. Open the taps of both supply and drain point.
4. Open the water supply tap.
5. Allow the system to spool through until no further contamination comes out
of the drain hose.
6. Then shut off the water supply.
7. Drain all remaining water from the system.
8. Now you can fill the system with glycol.
Warning
Before filling the solar heating system to replenish the heating fluid, make
certain that:
• The appliance is switched off (10.2 "
Decommissioning the water heater for
a short period").
• The solar heating system is switched off. Refer to the documentation of the
solar heating system.
• The appliance has cooled down sufficiently to prevent personal injury
(burns).
