I.1.12
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.1.13
Transport and pre-installation storage 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. During pre-installation storage the unit section
must
always be in the upright vertical position. The rotary heat
exchanger is not constructed for transportation and storage in a horizontal or tilted position.

Installation - mechanical
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 + 30
cm is kept free for service, inspection and also for replacement of fans, coils and exchanger, if needed.
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.
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.
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.
