Installation
Caution.
Risk of material damage due to heat trans-
fer during soldering.
▶
Do not carry out any welding work in the
area of the product's connectors.
▶
Before any welding work, insulate the wa-
ter-carrying pipes on the product's outlet
and the installation.
Danger!
Risk of scalding and/or damage due to
incorrect installation leading to escaping
water.
Mechanical stresses in the connection pipes
may lead to leaks.
▶
Ensure that there is no mechanical stress
when installing the connection pipes.
Caution.
Risk of damage in the pipelines due to
residue.
Residue from pipelines, such as welding
beads, scale, hemp, putty, rust and coarse
dirt, may be deposited in the product and
cause malfunctions.
▶
Flush the pipelines thoroughly before con-
necting to the product in order to remove
any possible residue.

Caution.
Risk of material damage caused by incor-
rect installation.
▶
Do not connect the product to extractor
hoods.
1.
Use only commercially available, insulated air ducts
with suitable heat insulation, to prevent energy loss
and condensation from forming on the air ducts.
Maximum length of the air pipes L1 + L2 (L1 = air in-
take pipe; L2 = air outlet pipe)

Note
In addition to the total
length, two 90° el-
bows can be added.

Note
In addition to the total
length, two 90° el-
bows can be added.
Note
In an installation with rigid pipes, elbows, at-
tachments and mesh create additional pres-
sure losses in the air duct system that may
correspond to five metres of straight pipe
length per element. Make sure that the max-
imum permitted lengths are not exceeded
with the elements used.
Protection devices must be installed at the openings
of the air ducts to prevent water or foreign bodies from
penetrating the pipelines (protective grille for vertical
walls, roof terminals).
Always protect the product against modification or
intervention in order to prevent water or foreign sub-
stances from penetrating as this may damage the
pipes or other components.
Use a circulation pump with a throughput between 0.5
and 4 l/min.
