Align the storage tank before it is filled: Adjust plastic
feet on the side flat areas using a size 30 open-ended
spanner. Check using a spirit level.
The average distance between the lower edge of the vertical ring
and the floor must be 40 mm to allow the insulation to be fitted!
The surface pressure by the feet is between 2.0 and 3.5
N/mm² depending on the storage tank size. Check the
floor structure - if necessary, the local pressure must be
reduced by increasing the contact surface:
After installing the storage tank (see p. 2), push the
round floor insulation under the cylinder (tilt the storage
tank slightly):

Hydraulic connection
The storage tank is connected to the different circuits in
accordance with the planning aids and a connection dia-
gram described in the technical documentation of the
CONTROL unit.
Connection: Comply with regulations of the local water
supply companies and DIN standards. Make all connec-
tions pressure resistant. All circuits must be completely
sealed, so that no atmospheric oxygen can enter the sys-
tem.
8.5.1
Boiler and heating circuit
The connections can also be piped to the side: with 90°
bends, e.g. with union nuts and flat gaskets.
Recommendation: Sludge filter on the heating circuit re-
turn.
8.5.2
Solar circuit
Do not connect the solar circuit and operate the solar
pump until the storage tank has been filled.
Recommendation: Smoothing section at the lowest point of
the solar circuit supply, so that corrosion products caused
by oxygen leaks are deposited there.
8.5.3
Cold and hot water connection
Make all connections in accordance with the respective
regulations, in particular in accordance with the DIN stan-
dards (see the diagram and designations below).
The cold water connection bend is enclosed with models
SOLUS II 560 L, SOLUS II 800/850 L and SOLUS II 1000
to prevent transport damage. Remove the protective sleeve
(in the centre on the upper cylinder lid), fit the connection
bend with the clamp screw fittings. Align with the other
connections.
Safety devices: Install the component-tested safety devices
in accordance with DIN 4753 Part 1 Par. 6.3.1 in the cold
water supply pipe.
Venting valve
The venting valve is fitted to the 3/8" connection provided
for this purpose via the armoured hose (incl. 2 x flat seals)
included in the scope of supply. Insert the venting valve
between tank and insulation before fitting the insulating
lid.
