The following instructions amongst others must be observed when
dealing with solar installations:
n The supply line should be installed in an ascending position and the
return flow should be in a descending position, thus allowing the
system to be drained.
n When draining, the heat carrying medium must be collected in a suit‐
able container.
Only pipe clamps with noise insulation inlays should be used.
Observe the general rules of fixing technology:
n Fixed pipelines should not be used as support for other pipelines
and components.
n Do not use pipe hooks.
n Observe distance to connectors.
n Observe the expansion direction – plan fixed and gliding points.
Affix the pipelines in such a way as to de-couple them from the installa‐
tion body, so that they cannot transfer any structure-borne sound,
resulting from thermal expansion or possible pressure surges, onto the
installation body or other components.
Observe the following fixing intervals:
Interval between the pipe clamps

the pipe clamps [m]

35.0 2.75
Pipelines expand with heat. Heat expansion is dependent on the mate‐
rial. Changes in length lead to tension within the installation. These ten‐
sions must be equalised with suitable measures.

2.3.3 Press connectors
Press connectors are available in a number of shapes. An overview of
the press connectors suitable for the system can be found in the cata‐
logue.
The press connectors in the Profipress S system consist of the following
materials:
n Copper
n Gunmetal/silicon bronze
Fig. 3: Press connectors
The press connectors have a circumferential bead in which the sealing
element lies. The connector is deformed upstream and downstream of
the bead and permanently connected to the pipe during pressing. The
sealing element is not deformed during pressing.
Fig. 4: SC-Contur
Viega press connectors are equipped with the SC-Contur. The SCContur is a safety technology that is certified by the DVGW and ensures
that the connector is guaranteed to be leaky in an unpressed state. In
this way, inadvertently unpressed connections are noticed immediately
when filling the system.
Viega ensures that inadvertently unpressed connections during installa‐
tion become visible when the system is filled.

2.4 Information for use
2.4.1 Corrosion
Galvanised components may not be used in solar installa‐
tions.
Overground pipelines and fittings in rooms do not normally require
external corrosion protection.
There are exceptions in the following cases:
n Contact with aggressive building materials such as nitrite or mate‐
rials containing ammonium
n in aggressive surroundings
If external corrosion protection is required, observe the pertinent guide‐
lines, see Ä „Regulations from section: Corrosion“ on page 6.

3 Handling
3.1 Transport
Observe the following when transporting pipes:
n Do not pull the pipes over the sill. The surface could be damaged.
n Secure pipes during transportation. Pipes may become bent due to
shifting.
n Do not damage the protective caps on the pipe ends and do not
remove them until immediately before mounting. Damaged pipe
ends may not be pressed.
In addition, observe the instructions provided by the pipe
manufacturer.
3.2 Storage
For storage, comply with the requirements specified in the applicable
regulations, see Ä „Regulations from section: Storage“ on page 6:
n Store components in a clean and dry place.
n Do not store the components directly on the floor.
n Provide at least three points of support for the storage of pipes.
n Where possible, store different sizes separately.
Store small sizes on top of larger sizes if separate storage is not pos‐
sible.
In addition, observe the instructions provided by the pipe
manufacturer.
3.3 Assembly information
3.3.1 Mounting instructions
System components may, in some cases, become damaged through
transportation and storage.
n Check all parts.
n Replace damaged components.
n Do not repair damaged components.
n Contaminated components may not be installed.
Checking system components
Handling
Profipress S 14 from 24

Do not use Teflon® tape to seal threaded connections in
solar installations, because the change in the creep behav‐
iour of the water glycol mixture may result in gradual leaki‐
ness.
Instead, use properly manufactured hemp packages.
3.3.2 Potential equalisation
DANGER!
Danger due to electrical current
An electric shock can lead to burns and serious injury and
even death.
Because all metallic piping systems conduct electricity,
unintentional contact with a live part can lead to the whole
piping system and components connected to it (e. g. radia‐
tors) becoming energised.
– Only allow electrical work to be carried out by qualified
electricians.
– Always integrate the metallic piping system into the
potential equalisation.
It is the fitter of the electrical system who is responsible for
ensuring that the potential equalisation is tested and
secured.
3.3.3 Permitted exchange of sealing elements
Important instruction
With their material-specific qualities, sealing elements in
press connectors are adapted for use with the corre‐
sponding media and/or the areas of use of the piping sys‐
tems and are generally only certified for them.
The exchange of a sealing element is generally permitted.
The sealing element must be exchanged for a designated
spare part for the intended application Ä Chapter 2.3.4
„Sealing elements“ on page 12. The use of other sealing ele‐
ments is not permitted.
Handling
Profipress S 15 from 24
Page 16
Exchanging a sealing element is permitted in the following situations:
n if the sealing element in the press connector is obviously damaged
and should be exchanged for a Viega replacement sealing element
made of the same material
n if an EPDM sealing element in Profipress connectors should be
exchanged for an FKM sealing element (higher thermal resistance,
e. g. for industrial use)

another onto a pipe without an interval, the pipe must not
be too short. If the pipe is not inserted up to the prescribed
insertion depth in the press connector during pressing, the
connection may become leaky.

3.4.2 Bending pipes
Copper pipes in the sizes d 12, 15, 18, 22 and 28 can be bent cold with
commercially available bending equipment (radius at least 3.5 x d).
The pipe ends (a) must be at least 50 mm long so that the press con‐
nectors can be mounted properly.
3.4.3 Shortening the pipes
NOTICE!
Leaky press connections due to damaged material!
Press connections can become leaky due to damaged
pipes or sealing elements.
Observe the following instructions to avoid damage to pipes
and sealing elements:
– Do not use cutting discs (angle grinders) or flame cutters
when cutting to length.
– Do not use grease or oils (e. g. cutting oil).
For information about tools, also see Ä Chapter 3.3.5 „Required
tools“ on page 18.
Cut the pipe properly using a pipe cutter or fine-toothed hacksaw.
Avoid grooves on the pipe surface.
3.4.4
Deburring the pipes
The pipe ends must be thoroughly deburred internally and externally
after shortening.
Deburring prevents the sealing element being damaged or the that the
press connector cants when mounted. Use of a deburrer (model 2292.2)
is recommended.

NOTICE!
Damage due to the wrong tool!
Do not use sanding disks or similar tools when deburring.
The pipes could be damaged by these.
Deburr the inside and outside of the pipe.
