6 Mounting and commissioning
WARNING
Scalding due to hot solar liquid and escaping steam.
XXTake all necessary measures during mounting, commis-
sioning and
maintenance of the solar pump assembly to
ensure that hot liquid does not pose any hazard to per-
sons.
X
X
Install the solar pump assembly in such a way that no
steam can get into the expansion vessel during stagna-
tion.
X
If the expansion vessel is mounted at the same height as
the solar pump assembly or higher than the solar pump
assembly, install a heat trap siphon.

Mounting and commissioning
)$(.65'6$(1 13
X
X
During heating up, liquid must be able to escape via the
discharge line of the safety valve (no obstructions).
Install the safety valve in such a way that it cannot be
shut off.
Do not install shut-off valves, filters or similar equipment.
X
Install the solar pump assembly in such a way that no ex-
ternal forces can act on the components after it has been
installed.
X
Do not overheat the components by welding or soldering
work performed on the system. Install the solar pump as-
sembly after completion of such welding or soldering
work.
X
Thoroughly flush the pipes prior to installing the solar
pump assembly. Impurities such as weld beads, hemp or
metal chips cause leaks of the safety valve and the check
valves.
X
Verify that the nominal pressure of the solar pump as-
sembly corresponds to the specification value of the sys-
tem.
X
Verify that the liquid in the system and the application ar-
ea of the solar pump assembly are compatible.
6.1 Mounting (.65'6$
;Sealing surfaces have been check for cleanliness and
damage.
;All pipe ends are perpendicular and have been deburred.
(.65'6$ is delivered ready to be installed. Do not dis-
assemble parts.
1. Remove the upper insulation.
2. Hold (.65'6$ with the lower insulation to the wall
(align with a level) and mark two positions.

Mounting and commissioning

3. Drill holes (Ø 10 mm) at the position of the two marks and
insert the enclosed dowels. Screw the long hanger bolt in-
to the top hole, the short hanger bolt into the bottom hole.
4. Fit (.65'6$ with the bottom insulation and secure it
with a washer and a nut.
5. Connect the pipes of the solar circuit to the connections of
the fittings.
6. Refit the upper insulation.

6.2.1 Discharge line of the safety valve
The discharge opening is designated by an arrow on the valve
body.
WARNING
Injuries and hazard of scalding due to hot liquid or steam
escaping via the discharge opening.
XXInstall the discharge line in such a way as to avoid any
damage or injuries due to escaping liquid and that th
e liq-
uid can be safely collected in a suitable collector tank for
solar liquid.
Fig. 5: Discharge line with container or collector tank for solar
liquid
X
X
The discharge line must have a gradient; its cross section
must have at least the same cross section as that of the
discharge opening.
X
The length of the discharge line must not exceed 2 m; the
maximum number of elbows is 2.
X
The discharge line must be accessible and observable.

Mounting and commissioning
)$(.65'6$(1 17
X
X
Drain the liquid discharged via the discharge line into a
container that can hold the total capacity of the system.
The discharged liquid must be collected and returned to
the system or disposed of by a specialised company.
Do not drain the discharged liquid into the sewage sys-
tem.

18 )$(.65'6$(1
6.3 Electrical connection
;Mains voltage is interrupted and cannot be switched on.
1. Connect the circulation pump described in the enclosed
operating instructions.
2. Route the connection cable of the circulation pump
through a cable duct to the bottom and connect it to the
solar controller. Observe the operating instructions of the
solar controller.
3. Standard shielded cable 3 x 1.5 mm² and up to Ø 10 mm
can be used to extend the connection cable.
6.4 Commissioning (.65'6$
In the case of (.65'6$, filling is possible via the filling
and flushing valves at the flow meter.
1. Attach a label in the vicinity of the discharge line or to the
safety valve with the following text:
"For safety reasons, liquid must be able to escape via
the discharge line during heating. Do not shut off!"
2. Verify that all connections are tight.
3. Set both ball valves to 45° position.
