CAUTION
Do not carry out a leak test when the installation is
exposed to direct solar radiation (risk of vaporisation) or
when it is freezing (risk of damage).
1. Fully open the flow valve (45° position) C1.
B2
2. Close the return valve C2 (position 90°).
3. Fully open the flowmeter valve A.
4. Connect the filling station to the solar station. The filling pipe must
C2
be connected to the filling valve B2. The draining pipe must be
connected to the drain cock B1 and to the heat transporting fluid
collection can.
B1
5. Open the filling valve B2 and the draining valve B1.
6. Switch on the filling station. Let the station run, making sure that
there is always enough fluid.
7. Vent several times with the vent plug D until the heat transporting
fluid comes out without any bubbles or particles.
8. To vent the pump part, open and slowly reclose the return valve
C2. .
9. Close the drain cock B1 and allow the pressure to rise to
5 bar (0.5 MPa) bar, then close the filling valve B2.
10.Open the return valve C2 and the flow valve C1 (0° position).
11.If the pressure in the installation drops, correct any tightness
problems.
12.When the test time has elapsed, allow the pressure in the system
to rise until it triggers the safety valve (operating check).
In the absence of air in the solar circuit, the test pressure must not
decrease.

n Filling
CAUTION
Before filling the installation, check the preload of the
expansion vessel according to the static height.
(Preload = static Height/10 + 0.3 bar (1.0 + 0.03 MPa)
(0.03 MPA)).
CAUTION
check the connection to the series of collectors and the
collector sensor connection.
