2.0
Important information
To ensure safety and correct operation please read and observe the following instructions carefully before proceeding.
The electrical connection must be fully isolated from the supply up to the final assembly! After the final
assembly the document must be handed out to the operator (tenant/owner).
2.1
Warning and safety instructions
Accompanying symbol is a safety-relevant prominent warning label. All safety regulations and/or symbols must
be absolutely adhered to, so that any danger situation is avoided.
2.2
Warranty – Exclusion of liability
If the preceding instructions are not observed all warranty claims and accommodation treatments are excluded. This
also applies to any liability claims extended to the manufacturer.
The use of accessories not offered or recommended by Helios is not permitted. Potential damages are not liable for
warranty.
2.3
Certificates
If the product is installed correctly and used to its intended purpose, it conforms to all applicable European Standards
at its date of manufacture.
2.4
Receipt
Please check delivery immediately on receipt for accuracy and damage. If damaged, please notify carrier immediately.
In case of delayed notification, any possible claim may be void.
2.5
Storage
When storing for a prolonged time the following steps are to be taken to avoid damaging influences:
sealing of bare parts with anti-corrosion agent, protection of motor by dry, air- dustproof packing (plastic bags with
drying agent and moisture indicators). The storage place must be water proof, vibration-free and free of temperature
variations.
When storing for several years or non rotation of motor an inspection of the bearings with possible relubrication and an
electrical inspection to VDE 0701 and VDE 0530 are absolutely necessary before starting operation. When transship-
ping (especially over longer distances) check if the packing is adequate for method and manner of transportation.
Damages due to improper transportation, storage or putting into operation are not liable for warranty.
2.6
Application/Operation
Die EC-centrifugal 'in-line' duct fans RR EC... from galvanised sheet steel are suitable for moving normal or slightly dus-
ty, almost non-aggressive and humid air at normal temperatures in the range of their performance curve. The fans are
not suitable for use in explosive areas.
For operation under difficult conditions i.e. high humidity, longer period of standstill, high pollution, excessive working
conditions through climatic, technical or electronic influences, further inquiry and operation release is necessary as the
standard execution might not be suitable. The motors have tropical insulation. The insulation class, the thermal load
possible and also the protection class are noted on the rating plate. It must be ensured that the standardized range of
application is not exceeded. The operational temperature (see rating plate) must not be exceeded. The fan may not be
used outdoors and may not come in contact with water during operation.
The fan may only be used according to its intended purpose !
2.7
Performance
The unit must be installed correctly to achieve the optimum performance. This applies to the installation of the unit, the
ducting and the replacement air supply. Incorrect installation conditions may lead to a reduction in the system perfor-
mance.
- Electrical data
The type plate informs about the electrical data. These have to be checked for agreement with the local conditions.
- Ventilation
The fan performances were determined on a test stand according to DIN 24163 part of 2. They are valid for the stan-
dard execution for free suction and discharge (approx. 1 m straight ducting). Incorrect installation conditions may lead
to a reduction in the system performance.
- Acoustics
The noise data also refers to the above mentioned configuration. Unfavourable operating conditions etc. can lead to an
increase of the given data. Noise data which are provided with distance data, refer to freefield conditions.
2.8
General information
Supply air duct: Every room which must be ventilated must have an supply air opening (which cannot be closed).
2.9
Safety
- All servicing and installations may only be carried out by a certified electrician.
- The fans may be operated only with the rated voltage indicated on the type plate.
- Technical data on type plate are to be adhered to without fail.
- The degree of protection given on the type plate is only valid with designed installation in accordance with these
installation and operating instructions.
