Centrifugal In-line EC Duct Fans – RR EC
Installation and Operating Instructions
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 are to be taken to avoid damaging influences: Motor protection
by dry, airtight and dust-proof packaging (plastic bag with desiccant and humidity indicators). Vibration-free, water-tight
and constant-temperature storage at a temperature in the range -20 °C to +40 °C.
In case of a storage period of more than three months or motor standstill, maintenance must be carried out before
commissioning according to chapter 8. In case of reshipment (above all, over longer distances; e.g. by sea), it must be
checked whether the packaging is suitable for the form and route of transport. Damages due to improper transportati-
on, storage or putting into operation are not liable for warranty.
2 .5 Performance data
The unit type plate gives an indication of the mandatory electrical values; which must be coordinated with the local
supply network. The fan performances were established on a test stand according to DIN EN ISO 5801.
2 .6 Noise data
Noise data that refers to certain distances apply to free field conditions. With regard to installation, the sound pressure
level can differ significantly from the catalogue data, as it is highly dependent on the installation conditions, i.e. on the
absorption capability of the room and the room size among other factors.
2 .7 Air-flow direction and direction of rotation
The units have a fixed direction of rotation and air-flow direction (they are not reversible), which is indicated by the
arrows on the device. The air-flow direction can be determined during installation.
2 .8 Protection against contact
- Centrifugal in-line fans RR EC are not delivered with fan protection guards as standard. Depending on the installation
conditions, protection against contact may be necessary on the suction and/or discharge side. Corresponding protec-
tion guards are available as accessories.
- Fans which are protected by their installation method (e.g. installation in ventilation ducts or closed assemblies) do
not require protection guards if the plant provides the necessary level of safety. Please note that the operator is
responsible for complying with the current standard and can be held liable for accidents as a consequence of missing
protection systems.
2 .9 Motor protection
All RR EC.. fans are equipped with an integrated electronic temperature monitoring system for the EC motor and the
electronics. This protects the motor against overloading and overheating.
m
If the temperature monitoring system is frequently triggered (standstill), the fan must be inspected by a
specialist according to section 1 .4 .
2 .10 Condensation
If the fan is used intermittently, especially in a humid and warm environment, or if variations in temperature occur, con-
densation may build up in the motor and draining off must be ensured. In case of condensation in the ducting and fan
casing appropriate measures must be taken during installation (water sack, drainage line). Under no circumstances
must the motor come into contact with water.
