Now connect a hose, which pumps the glycol-
water mixture from the filling station into the
system, to the connection (9). The ball valve
at connection (9) is opened - see figure 4 // 10.
The tap (8) is closed - see figure 4 // 10.
A hose is also connected to connection (7).
This leads back into the container of the filling
station. The ball valve on connection (7) is
opened - see figure 4 // 10.
Now pump the glycol-water mixture with
the filling station into the system until liquid
emerges at connection (7). Switch off the filling
station and close the ball valves at connection
(7) and (9).
Step 1: Filling of the installation
Now open the tap (8) and let the system run
in manual mode for approx. 15 minutes - see
installation instructions for the controller - in
order to trap any air pockets from the system
in the SolBox.
