Swegon BlueBox Tau SKY Hi HP Instructions For Installation, Use And Maintenance Manual page 36

The frame installation surface must be perfectly flat.
The frame installation surface must be capable of supporting at least 5 times the unit weight.
Screws, bolts and nuts must be tightened properly before the unit is installed on the frame. Check the tighte-
ning level periodically.
The frame must be anchored to the ground at all required points.
Below are the instructions for frame assembly.
1. Screw the 4 metal adjustable feet to the frame legs (Fig. F.3).
2. Adjust the feet until they are all at the same height: use a tape measure to check the height. Then tighten the nuts in the
feet using a spanner to lock them in place at the desired height (Fig. F.4).
3. Install two cross beams - one for each frame leg - and tighten the screws to the legs (Fig. F.5).
4. Use a tape measure to measure the distance between the external unit mounts on the long side of the unit - the distance
to be measured is that between the centres of the slots (Fig. F.6).
5. Join the legs using the cross beams. Adjust the cross beams making sure that the distance between the centres equals
the distance between the mounts of the external unit (Fig. F.7).
6. After cross beam adjustment, secure the beams using screws, washers and nuts and tighten them properly (Fig. F.8).
7. Install the 4 rubber anti-vibration mounts (two on each side) on the slots in the frame. Secure them from the bottom using
nuts and washers, without tightening them all the way down (Fig. F.9).
8. Use a tape measure to measure the distance between the external unit mounts on the short side of the unit - the distance
to be measured is that between the centres of the slots (Fig. F.6). Set the anti-vibration mounts at the measured distance
(Fig. F.10).
9. Tighten the nuts of the anti-vibration mounts using a socket spanner (Fig. F.11).
10. Put the frame in place in the installation area and mark the position of the holes for the frame feet on the installation
surface (Fig. F.12).
Check that the min. distances for external unit installation, as specified in section "External unit positioning"
in this manual, are complied with.
11. Pierce the surface at the marked points with the help of a drill with a Ø 8 mm bit (Fig. F.13).
12. Fit the expansion anchors in the holes drilled on the surface. Place the frame so that the holes in the feet match the
anchors. Secure the frame to the ground by tightening the expansion screws to the anchors (Fig. F.14).
13. Lift the external unit with the help of suitable lifting equipment and place it on the anti-vibration mounts (Fig. F.15).
For unit lifting operations refer to the section titled "Handling" in this manual.
14. Secure the external unit to the anti-vibration mounts using nuts and washers and tighten the nuts properly with a span-
ner (Fig. F.16).
After unit installation, use a bubble level to check that the unit is perfectly horizontal.
