DA 17K Tunnel Inlet
4 Mounting Guide
1 Product description
The DA 17K Tunnel Inlet, outside is used as an air inlet in houses with Tunnel Ventilation or Combi-Tunnel Ven-
tilation.
The tunnel inlet can be mounted directly on walls or sandwich panels.
The tunnel inlet is made of PVC (polyvinyl chloride) with insulation.
The inlet is supplied with the inlet flaps installed. The regulation set is installed on-site.
When mounting externally, the inlet is turned in the opposite direction in relation to when mounting internally.

433716 DA 17K tunnel inlet, highly ins. outside
DA 17K tunnel inlet, outside is highly insulated and used for external as-
sembly on the wall.
When you mount the tunnel inlet on the outside the inlet does not take up
space inside the livestock house. It also prevents the animals from getting a
grip of the strings or connectors.
The mounting parts are used for assembling the DA 17K outside.
DA 17K outside must always be protected against wind and weathering –
e.g. by placing the tunnel inlets in combination with either cooling pads, light
trap flex or the like.
433717 DA 17K tunnel inlet, semi ins. outside
DA tunnel inlet, outside is used for external assembly on the wall where in-
sulation is not necessary.
When you mount the tunnel inlet on the outside, the inlet does not take up
space inside the livestock house. It also prevents the animals from getting a
grip of the strings or connectors.
The mounting parts are used for assembly of the DA 17K outside.
DA 17K outside must always be protected against wind and weathering –
e.g. by placing the tunnel inlets in combination with either cooling pads, light
trap flex or the like.

less than -10°C.
Supplied with mounting set and mounting guide.
One per inlet.

3.2 Wall inlet positioning
The positioning of the inlet in a wall depends on the layout of the building and house. The positioning may there-
fore only be made according to directions communicated by or representatives of SKOV A/S.
3.3 Mounting of tunnel inlet
3.3.1 Preparing hole in wall
Mark out the correct number of holes according to mea-
surements.
Remember to use a spirit level at all times.

DA 17K Tunnel Inlet
Mounting Guide 9
Make a diagonal measurement.
Cut the holes.
3.3.2 Mounting in wall
Ensure that the inlet is placed in the middle of the hole.
Center the inlet in the hole with wedges.
Avoid pressing the inlet into place when mounting.
Make sure that the inlet flaps close tightly.

DA 17K Tunnel Inlet
10 Mounting Guide
Pre-drill the holes according to the instructions be-
low
Use a spirit level to ensure that the inlet has a correct
position.
Screw all 24 screws into the pre-drilled holes and mount
the inlet on the wall.
Center mark or 2mm hole when mounting in a sandwich
panel. Material thickness ≤ 1mm.
4mm hole when mounting in steel profiles. Material thick-
ness >1mm ≤ 2mm.
4.5 mm hole when mounting in steel profiles. Material
thickness >2 mm ≤ 4 mm.
Recommended screw: Tapping screw 4.8x70 A2.
Recommended tightening: 5.1 Nm.
Please make sure not to over-tighten the screws as they
are tightened directly against plastic.
Make sure that the internal dimensions still correspond
to those on the drawing.
3.3.3 Check the tightness
Press on the 5 inlet flaps at both ends.
No gaps = OK

DA 17K Tunnel Inlet
Mounting Guide 11
If there is a gap, use wedges to straighten the frame.
If necessary, use wedges from stacking blocks.
Break off the wedge.
Loosen the screws and insert wedges behind the inlet
frame until all flaps close tightly.
Tighten the screws again.

DA 17K Tunnel Inlet
12 Mounting Guide
Check that there are no gaps on both sides of all five in-
let flaps.
If only one flap has gaps, it may be because the flap is
twisted.
The flap is corrected by twisting the flap in the opposite
direction.

Mounting Guide 13
3.3.4 Foaming
The excess part of the wedges should be removed before foaming.
Wet the faces with water from a mist sprayer before proceeding with the foaming.
1 component Polyurethane foam is used for foaming.
A. Foam the entire depth of the inlet in the corners and approx. 100 mm to each side of the corners.
B. It is important to foam the edge only on the middle part of the inlet, otherwise the foam may cause the inlet to
warp.
