Transport
WARNING: Observe enclosed safety instruc-
tion sheet.
NOTICE: During transport, ensure that the im-
peller is not knocked or distorted. Never fasten
transport equipment to the motor, directly to the
weather protection hood or impeller. Ensure that
the impeller can rotate freely around its axis dur-
ing transport and that there are no foreign bodies
hampering movement.
1. Attach suitable transport equipment
to the fan's metal base or pallet. Do
not load sensitive unit components
during transport. Note the centre of
gravity of the unit.
2. Carefully lower the fan or complete
fan pallet onto the roof, at the install-
ation site, using a crane.
Storage
• Only store fans in a dry location and resting
in a horizontal position on the metal base (at
-20 °C to +60 °C). Avoid storage periods that
are too long.
• Protect the fan from impact that could damage
it.
• Do not store the fan in an environment contain-
ing corrosive substances.
• Avoid the impeller remaining idle for long peri-
ods (both in storage and when already in-
stalled). During idle periods, regularly turn the
impeller by hand and check that it can move
freely to prevent damage to the bearings. Fail-
ure to comply with these requirements releases
the manufacturer from all guarantees and liabil-
ity.
• Before installation, check that the moving parts
(impeller, shutters) can move freely.
• Do not store the fans in the vicinity of running
and vibrating machinery. This would expose the
impeller bearings to excessive strain, which
could result in imbalance during operation.
• If stored for lengthy periods, protect the fans
from dust, moisture and sunlight.

9 Installation site

Only install the fan in locations suitable in terms
of load-bearing capacity, condition, ventilation,
protection against temperature and fire → plan-
ning documents.
When selecting the installation site, note the
following conditions
• The installation site must be level and capable
of supporting the static and dynamic load as
well as the fan's natural frequency in order to
avoid deformation and damage to the fan. Re-
verberations caused by the fan's natural fre-
quency must be avoided. Follow the planning
documents. If necessary, modify the fan install-
ation. For high-speed fans, plan the installation
on a reinforced concrete base.
• Note that the roof's permissible load-bearing
capacity must be a min. of 200 kg/m² or for
heavy units a min. of 300 kg/m².
• If installing on steel beams, it is absolutely es-
sential that these structures have a natural fre-
quency > 50% of the fan speed. To prevent vi-
brations from spreading via the foundation, we
recommend using vibration-damping support
plates. These are to be mounted at the points
intended for them. The housing and internal
structure must not be deformed.
• Note the permissible distances from building
components (for air ducts on the inlet and outlet
side):
1.5x impeller diameter as distance from wall for
applications without air ducts.
2.5x impeller diameter as distance for first curve
of the fan outlet.
Internal minimum curvature radius of curves
should equal the duct diameter.
• The fan must not blow out air into areas
where there are people or animals so that
neither injury nor damage to persons can result
from either hot, expelled air or dirt and other
small particles flying around.
• Take account of the minimum distances for in-
stallation and maintenance work. Ensure that
there is enough space for installation, cleaning
and maintenance work. Limited available space
may present a source of danger.
• Observe the distances to other façade compon-
ents to avoid sound bridges to the building
structure. If necessary, use decoupling ele-
ments.
