B
Turn the valves on the filling station so that they are in mixing position
(
Æ
Figure 24).

B
Start the filling station (pump) and mix the collector circuit fluid for at
least two minutes.
B
Turn the valves on the filling station to filling position and fill the circuit
with collector circuit fluid
(
Æ
Figure 25).

B
When the fluid level has fallen to 25% in the filling station, the pump
should be stopped and more collector circuit fluid should be filled and
mixed.
B
When the circuit is full and air no longer comes from the return pipe,
the pump should be run again for at least 60 minutes (the fluid should
be clear and should not contain any bubbles).
B
The circuit must be pressurized when venting is complete. Turn the
valves on the filling unit to pressure increase position and pressurize
the circuit to 2.5 to 3 bar (
Æ
Figure 26).

B
Turn the valves of the filling unit to normal position (
Æ
Figure 27) and
turn off the pump on the filling station.

B
Disconnect the hoses and insulate the filling unit.
If other equipment is used, the following is required, among other things:
•
A clean container with capacity for the amount of collector circuit fluid
that is required
•
An additional container for collection of contaminated collector
circuit fluid
•
Submerged pump with filter, flow capacity of min. 6 m
3
/h, pressure
height of 60 to 80 m
•
Two hoses, Ø 25 mm
Repeat the following steps for each circuit. One circuit at
a time is filled with collector circuit fluid. Keep the valves
closed in the other loops during the process.
