Sections connection is out of the standard offer of VTS. It is possible to purchase additional
option to connect to the section by Authorized Service VTS.
!
When the customer connect the section by himself should follow the separate instructions,
supplied with AHU in the mounting set.

During connecting the section one should pay attention on the applying glue on the casing
locks (section connection without using glue will result in a lack of casing tightness - warranty
claims because of this will not be considered).
!
Optionally, in the mounting set provided with AHU can be included butyl tape, to additional
seal the connection of section. Additional seal at the connection of section is recommended
especially for the external AHUs.
!
In case of assembly on site:
!
Assembly must be carried out on hardened and dry surface. Hardened surfaces are understood
as flat, leveled and hard surface, which does not change its properties under influence of
atmospheric conditions and is resistant to any damages relating to placing the AHU on it as
well as regular operation.
!
Assembly can be carried out in ambient temperature allowing to perform correctly all technical
procedures of the assembly, i.e. within temperature range: from +5 to +35ºC.
!
In case of outdoor assembly, the procedure can be carried out in precipitation-free conditions.
!
It is acceptable to start the assembly provided that all safety and security requirements are
met.
!
Minimum distance of an assembly location:
• AHU width + 4 meters (2 meters on each AHU side),

against the snow, and base frame should be placed on the level not lower than height of snow level in that region
and relevant regulations.
In condition of the low temperature, the heat lost is increased, It can affect rise of demand for heating.
Controls elements such as: a heat node of the heating capacity regulation, three-way valves, water pumps,
thermo-manometers, valves, as well as frequency converters should be placed in the room with temperature
higher than +5°C.
