1.0 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 ! Keep the installation and
operating instructions as a reference at the device. After the final assembly the document must be handed out to the
operator (tenant/owner).
1.1 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.
1.2 Warranty – Exclusion of liability
If the preceding instructions are not observed all warranty claims and accommodation treatment are excluded.
This also applies to any liability claims extended to the manufacturer.
The use of accessories not offered or recommended is not permitted. Potential damages are not liable for
warranty.
1.3 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.
1.4 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.
1.5 Storage
When storing for a prolonged time the following steps are to be taken to avoid damaging influences: 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 transhipping
(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.
1.6 Application/Operation
The fans are designed for air extraction of living spaces. If the unit is to be used in other applications where high
humidity, excessive dust, temperature in excess of 40 °C or long periods at standstill (not running), please contact your
local dealer for advice. This also applies for special technical and electrical applications. The complete fan corresponds
to protection IP 45 (jet water-protected) , protection class II and is suitable for use in zone 1 of bathrooms.
The fan may only be used for its intended purpose !
1.7 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.
If installing in a room where the fan can affect a fuel burning device (e.g. a gas boiler) which has a balanced flue, it is the
installer’s responsibility to ensure that there is sufficient replacement air to prevent fumes being drawn down the flue
when the fan is operating at maximum extract rate.
The catalogue noise levels stated are A-rated sound power levels LWA (to DIN 45635 T.1). The A-rated sound pressu-
re level LPA depends on the acoustic condition in the room in which it is installed. These affect considerably the adju-
sting noise.
1.8 General information
Intake air duct: Every room which must be ventilated must have an intake air opening to prevent negative pressure
conditions.
1.9 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 and with closed fascia.
