Shipping

The fan is packed ex works in such a way that it is protected against normal transport strain. Carry out the shipping
carefully. It is recommended to leave the fan in the original packaging. The unit must be kept in the housing for trans-
portation or installation. Only use appropriate lifting equipment and fastening devices.
Do not transport fan on the connection cables, terminal box or impeller!
Do not stand under suspended loads!
2 .3

Receipt

The shipment must be checked for damage and correctness immediately upon delivery. If there is any damage,
promptly report the damage with the assistance of the transport company. If complaints are not made within the agreed
period, any claims could be lost.
2 .4

Storage

When storing for a prolonged time the following steps should be taken to avoid damage to the product, protection by
dry air and dustproof packing (plastic bags with drying agent and moisture indicators). The storage area must be free of
moisture, vibration and temperature variations. Storage temperature -20 °C to +50 °C, and these limits
must not be exceeded.
In case of storage or motor standstill for longer than three months, maintenance must be carried out according to
chapter 7 before commissioning.
When transhipping (especially over longer distances) check if the packing is adequate for method and manner of trans-
portation. Damages due to improper transportation, storage or commissioning are not liable for warranty.

Performance data

The unit must be installed correctly and proper supply and exhaust air flow must be ensured to achieve the optimum
performance.
– Electrical parameters
The motor rating plate provides information on the electrical data. This data must be examined for its conformity to the
local conditions.
– Air delivery
The fan performances were determined on a test stand according to DIN 24163, part 2. They are valid for the normal
design with free suction and discharge (straight duct section = 2x duct diameter). Diverging execution and adverse
installation- and operation conditions can lead to a reduction of performance.
– Acoustics
The noise data also refers to the above mentioned configuration. Adverse operating conditions etc. can lead to an
increase of the given data. Noise problems can be eliminated by using flexible sound attenuators (see Helios accesso-
ries).
2 .6

Noise data

The noise levels published in the catalogue can differ considerably after installation as sound pressure levels depend on
the absorption capacity on the room, the place of installation and other factors. Sound reduction is possible by using
attenuators and speed controllers (control).
2 .7

Air flow direction and direction of rotation

The motors have a fixed air flow direction and direction of rotation, i.e. they are not reversible. The air flow direction and
direction of rotation are indicated by arrows. (Fig.1).
2 .8

Protection against accidental contact

m
When installing observe the valid regulations for labour protection and accident prevention! Protection
against accidental contact according to DIN EN ISO 13857 must be ensured!
Any contact with rotating parts must be avoided. Make sure that no textiles or other materials which could be sucked
in (such as clothing of persons) are close to the suction area of the fan.
Fans protected by their installation ( in ventilation ducts or closed aggregates) do not need a protection guard, if the
installation guarantees the same protection. We emphasize that the installer will be held responsible for accidents
occurring as a result of missing protection devices.
2 .9 Motor protection device
The types MV EC 125-250 are equipped with a thermal fuse in the motor to protect against overheating.
The type MV EC 315 is equipped with a manual resettable thermal contact in the motor to protect against overheating.
