Safety Information
This machinery must not be put into operation until prior to reading mounting
instructions
and
safety information. All fans are intended for transportation of air
in
air handling systems. If
installed
in no heated rooms, the fan casing has to be insulated in order to avoid condensation
.
They are meant to be used after building them into machines or duct systems or after contact
protection grid have been
installed.
Fans with duct connections must be connected to ducts on
both sides (inlet/outlet). When there is a risk of water entering the motor, via the ducts,
external protection is required. No moving parts shall be accessible after installation. The fans
are not to be used in hazardous environments or connected to flue ducts. The fans must not be
installed
outdoors
(with
exception of roof fans and fans with, for this purpose: corresponding IP
class). If the fans are installed without insulation in non-heated areas there is a risk of
condensation. Safety accessories (i
.
e. motor protection, safety grille) may not be dismounted,
short cut or disconnected.
CAUTION!
Before servicing or maintenance, switch off power, (all-
pole circuit breaker), and make sure the impeller has come a standstill.
CAUTION!
The fans
can have sharp edges and corners which may cause
injuries.
CAUTION!
Be careful when
opening the fans service-hatches (swing-out), the fan and motor assembled on the hatch is
relatively heavy.
Transportation and Storage
All fans are packaged at the factory to withstand normal transport handling. When handling the
goods
use
suitable lifting equipment in order to avoid damage to fans and personnel. Do not lift
the fans by the connecting cable, connection box, impeller or inlet cone. Avoid blows and
shock
loads. Store the fans in a dry place protected from weather and dirt until final installation.
Operation
Before initial operation, check the following:
- Electrical connection has been properly completed.
- Protective conductor has been connected
.
- Motor protection installed
.
- Safety devices in place (protection grid)
- Leftover
installation
materials and foreign materials have been removed from the casing.
When putting into operation, check the following:
- Connection data corresponds to
the
specifications on
the
nameplate
:
Maximum v6%,
-10%, according to IEC 38
.
Rated current must not be exceeded with more than 5% at rated
voltage.
CAUTION!
When speed regulating by reducing the voltage the motor current may
exceed the rated current at a lower voltage. In this case the motor windings are protected by
the thermal contact. The minimum static fall of pressure
must
observe
.
- The direction of rotation should correspond to direction of rotation arrow
- Smoothness of motor operation, (no abnormal noises)
- Fans must only be operated by a person that has sustainable knowledge or education within
this field or handling must be carried out with the supervision of such person.
