| Instructions for unloading on the site as well as installation and connection
I.2.2 Supporting surface
Caution
Duct work must be sound insulated and must not be mounted directly on beams, trusses or other critical
building parts.
Caution
The surface beneath the unit must be level, horizontal and vibration-free. The surface must be able to
withstand the load of the AHU. Weights of the sections are written in Annex 2.
I.2.3 Adjustable feet under legs or base frame and transport of sections
Adjustable feet are provided in a carton box placed inside the unit. Adjustable feet are delivered for indoor units and
not for outdoor units.
Sections can be transported on the site by hand manual forklifts or similar. The frame profiles in the edges of the sec-
tions have carrying capacity for lifting by the hand manual forklifts.
I.2.4 Base frame assembly
Base frame is delivered unassembled for the indoor units that are delivered in sections on pallets. Assembly of the base
frame is illustrated on 4 pages in a manual in a plastic bag which is attached to one of the large base frame parts.
The 4 pages with the illustration regarding the assembly of the base frame are also available in this user manual in An-
nex 4, 5, 6 or7.
There are two types of base frames:
1. 118 mm high base frames
2. 218 mm high base frames
There are 4 different manuals and each of them illustrates the assembly of the 4 different types of base frames:
1. Manual about the 118 mm high base frames for AHUs in the sizes from Geniox 10 to Geniox 18. The name of this
manual is – Base frame 118 sizes10 - 18
2. Manual about the 118 mm high base frames for AHUs in the sizes from Geniox 20 to Geniox 31. The name of the
manual is – Base frame 118 sizes20 - 31
3. Manual about the 218 mm high base frames for AHUs in the sizes from Geniox 10 to Geniox 18. The name of the
manual is – Base frame 218 sizes10 - 18
4. Manual about the 218 mm high base frames for AHUs in the sizes from Geniox 20 to Geniox 31. The name of the
manual is – Base frame 218 sizes20 - 31
Mount adjustable feet with a distance of maximum 1500 mm between each foot under the base frame. The base frame
can now be levelled by the adjustable feet. The next step is to place and assemble AHU sections on the base frame.
I.2.5 Base frames for outdoor units
Outdoor units must be installed on 218 mm high base frames and are always fitted to the AHU sections. Hot-dip galvan-
ized base frames are recommended for outdoor units. Systemair delivers these base frames without the above men-
tioned adjustable feet.
I.2.6 Outdoor units — support under the base frame of the unit
The installer must provide a frame that supports the base frame of the unit under the inspection side and under the
back side of the unit. The frame must support the base frames of the unit under the entire length of the unit.
