I.1.8 Roof unit with steel roof
Caution
For units with steel plate roof, the steel plates are delivered uninstalled on a separate pallet. Do not step or
walk on the plates.
I.1.9 Pre-assembly storage
The AHU must be protected from the weather and accidental impact. Plastic packaging must be removed and the unit
covered with tarpaulin or similar materials. In order to minimize condensation, sufficient air circulation must be ensured
between the covering and the unit.
I.1.10 Tilt less than 30˚ during transportation of the section with heat pump
During transportation, the unit section must always be in the upright position or tilted less than 30˚. If it is necessary to
tilt the unit more than 30˚, the suction pipe of the compressor must point upwards to prevent the escape of oil from the
compressor sump.
I.1.11 Transport of rotary heat exchanger — always in vertical position
During transportation, the unit section must always be in the upright vertical position and never in a horizontal or tilted
position. The rotary heat exchanger is not constructed for transportation in a horizontal or tilted position.

I.2.1 Free area in front of and above the unit
Important
When positioning the unit on the site, it must be ensured that an area with the same width as the unit is
kept free for service and inspection and also for replacement of fans and exchanger, if needed. The width of
the free area must be at least 900 mm.
Important
For safe access to the cabinet with electrical components, if the cabinet is placed on top of the unit, the free
area from the upper edge of the cabinet to the ceiling must be at least 700 mm.
