5 Set-up
–
Region with ground frost: Minimum depth: 900 mm
–
Region without ground frost: Minimum depth: 600 mm
▶
Calculate the height (B) in accordance with local condi-
tions.
▶
Create two concrete strip foundations (4). The recom-
mended dimensions can be found in the figure.
▶
Add a gravel bed between and beside the strip founda-
tions (2) to divert the condensate.
5.8.2
Installing the product
1.
Use the appropriate products from the accessories,
depending on the required installation type.
–
Small damping feet
–
Large damping feet
–
Raised base and small damping feet
2.
Align the product exactly horizontally.
5.8.3
Installing the condensate discharge pipe
Danger!
Risk of injury due to frozen condensate.
Frozen condensate on paths may cause falls.
▶
Ensure that condensate does not dis-
charge onto paths and that ice cannot
build up there.
Condition: Region with ground frost
▶
Connect the condensate discharge tundish to the pro-
duct's floor plate, and secure this in place by turning it by
a 1/4 rotation.
▶
Slide the heating wire through the condensate discharge
tundish.
▶
Ensure that the condensate discharge tundish is posi-
tioned in the centre above the downpipe. See dimension
drawing (→ Page 119).
Condition: Region without ground frost
▶
Connect the condensate discharge tundish to the pro-
duct's floor plate, and secure this in place by turning it by
a 1/4 rotation.
▶
Connect the condensate discharge tundish to an elbow
and a condensate discharge hose.
▶
Slide the heating wire through the condensate discharge
tundish and the elbow into the condensate discharge
hose.

Wall installation
5.9.1
Guaranteeing occupational safety
▶
Ensure that the installation position on the wall can be
safely accessed.
▶
If the work on the product takes place at a height above
3 m, install technical fall protection.
▶
Observe the local laws and regulations.

5.9.2
Installing the product
1.
Check the design and load-bearing capacity of the wall.
Note the weight of the product.
2.
Use the unit mounting bracket that is suitable for wall
mounting from the accessories.
3.
Use the small damping feet from the accessories.
4.
Align the product exactly horizontally.
5.9.3
Installing the condensate discharge pipe
Danger!
Risk of injury due to frozen condensate.
Frozen condensate on paths may cause falls.
▶
Ensure that condensate does not dis-
charge onto paths and that ice cannot
build up there.
1.
Connect the condensate discharge tundish to the pro-
duct's floor plate, and secure this in place by turning it
by a 1/4 rotation.
2.
Below the product, create a gravel bed into which any
condensate can drain.
5.10
Flat-roof installation
5.10.1 Guaranteeing occupational safety
▶
Ensure that the flat roof can be safely accessed.
▶
Maintain a safety area of 2 m to the fall edge, plus the
clearance that is required for working on the product. The
safety area must not be entered.
▶
If this is not possible, then install technical fall protec-
tion at the fall edge, for example reliable railings. Altern-
atively, set up technical safety catch equipment, for ex-
ample scaffolding or safety nets.
▶
Maintain sufficient clearance to any roof escape hatches
and flat-roof windows. When carrying out the work, use
suitable protective equipment (e.g. barriers) to prevent
you from stepping on or falling through any escape
hatches and flat-roof windows.
5.10.2 Installing the product
Warning.
Risk of injury due to toppling over in the
wind.
The product may topple over if there is a wind
load.
▶
Use a concrete base and an anti-slip pro-
tective mat. Screw the product to the con-
crete base.
1.
Use the large damping feet from the accessories.
2.
Align the product exactly horizontally.
