Screw the AHU casing units evenly to the end
faces of the base frames and to the casing unit
connectors.
Installing AHU casing units on top of each other
Do not start assembling the upper units until you have
completed assembly of the lower units, including screw-
fixing the module connectors and the base frame.
Follow the assembly instructions carefully as otherwise
the unit may become damaged, the casing units may
start shifting or, if the unit is installed outdoors, water
may get into the unit.
Factory drilled holes indicate where the lower and
upper AHU casing units have to be joined. Align and
fix the casing units according to these holes.
Be sure to use all of the fixing points. If an assembly
point is difficult to access, check if it is possible to
assemble the units in a different order.
Ensure that the position is correct based on the
screw joints on the operating side.
Ensure that no water can get into the unit at the fac-
tory provided joints.
If in doubt, consult TROX.
