300l variant:
• Fit the casing as follows:
Lay the strip with the holes on the retaining pins and
screw it down securely.
400l and 500l variants:
• Fit the jacket by positioning an aluminium rail with the
holes on the locking pins and fastening it with the
plastic screws. To do this, you need only snap in the
screws, not turn them.
• After fastening the two aluminium rails, attach the
cover cap and the front covers.
h
Note!
Check that the front covers are correctly seat-
ed, to prevent heat loss.
• Align the cylinder vertically with the adjustable feet.
5.4 Connecting
the
cylinder
VIH S:
Proceed as follows when installing the cylinder
(see Fig. 5.2):
• Connect the heating flow (
4
) and return (
6
) to the
cylinder.
• Connect the solar flow (
8
) and return (
10
) to the cylin-
der.
h
Note!
Observe the enclosed solar system manual!
• Install the cold water pipe (
11
) with the necessary
safety devices:
If the water pressure at the installation location is less
than 10 bar, a proof-tested DN 25 safety group can be
used.
• Install a T-piece in the cold water pipe between the
cylinder connection and the safety group for draining
the cylinder.
• Install the hot water pipe (
3
) and, if necessary, the
secondary return (
7
).
VIH R:
Proceed as follows when installing the cylinder
(see Fig. 5.3):
• Connect the heating flow (
5
) and return (
7
) to the cyl-
inder.
• Install the cold water pipe (
8
) with the necessary safe-
ty devices:
If the water pressure at the installation location is less
than 10 bar, a proof-tested DN 25 safety group can be
used.
• Install a T-piece in the cold water pipe between the
cylinder connection and the safety group for draining
the cylinder.
• Install the hot water pipe (
3
) and, if necessary, the
secondary return (
4
).
VIH RW:
Proceed as follows when installing the cylinder
(see Fig. 5.4):
• Connect the heating flow (
4
) and return (
7
) to the cyl-
inder.
• Install the cold water pipe (
8
) with the necessary safe-
ty devices:
If the water pressure at the installation location is less
than 10 bar, a proof-tested DN 25 safety group can be
used.
• Install a T-piece in the cold water pipe between the
cylinder connection and the safety group for draining
the cylinder.
• Install the hot water pipe (
3
) and, if necessary, the
secondary return (
5
).
h
Note!
As the use of a secondary return results in
standby losses, it should only be connected if
the hot water network is widely distributed.
If a secondary return is necessary, the circula-
tion pump must be fitted with a time switch in
accordance with the Heating Installation Ordi-
nance.
• Fit stainless steel caps to the unused connections, en-
suring they are pressure-tight.
• Carry out the electrical wiring if necessary.
h
Note!
Connect all the supply lines with screw cou-
plings.
H
Danger!
Risk of scalding!
Please note that a hot water thermostatic
mixer must not be installed in any secondary
return area that might be present, as the scald-
ing protection would no longer be guaranteed.
In such cases, install the hot water thermo-
static mixer downstream of the secondary re-
turn area.
