Flat Centrifugal Fan Boxes – SlimVent SV..
Installation and Operating Instructions
– The electrical connection and initial commissioning must only be carried out by qualified electricians
according to the information in the attached wiring diagrams.
– All relevant standards, safety regulations (e.g. DIN VDE 0100), as well as the technical connection conditions of
energy suppliers are to be adhered to!
– A multipole mains section switch/isolator, with a minimum contact opening of 3 mm (VDE 0700 T1 7.12.2/
EN 60335-1) is mandatory!
– Network configuration, voltage and frequency must be consistent with the rating plate information..
– Check the waterproofing of the connection cable and tight clamping of the strands.
– Metal cable screws must not be used when connecting to plastic terminal boxes.
– Insert the supply line so that no water can get in along the cable in case of water exposure.
– Check designated use of fan
– Compare mains voltage to rating plate data
– Check fan for solid mounting and professional electrical installation
– Check all parts for tightness, particularly screws, protection guards. Do not loosen screws in the process!
– Check free movement of the impeller.
Wear protective gloves when checking unhindered running of impeller!
– Compare power consumption to rating plate data
– Check protective conductor connection
6.5 Operation
In order to ensure the proper functioning of the fan, the following must be checked regularly:
– Formation of dust or dirt deposits in the casing or on the motor and impeller
– Freewheeling of impeller.
Wear protective gloves when checking freewheeling of impeller!
– Occurrence of excessive vibration and noise
If excessive vibration or noise occurs, maintenance must be carried out according to the instructions in chapter 8.
7.0 Functional description SV
The SlimVent SV.. are speed-controllable by means of voltage reduction. The speed adjustment by
voltage reduction can take place with phase angle units or transformers (TSW..). When using electronic controllers or
regulators (ESU../ESA..) there may be electromagnetic motor noises (humming) in the lower speed range. This is not
the case when using transformer controllers. Thus, this solution is preferred in noise-critical installations.
NOTE!
In order to ensure sufficient motor cooling, a minimum speed/voltage, which also depends on on-site resistan-
ces, wind pressure, etc., must be observed.
With regard to the calculation of the control units, it must be noted that there may be current peaks in the variance. The
control units must therefore be dimensioned according to our technical data. Suitable control units are offered as
accessories.
With regard to fan types SVR / SVS 100 to 160, two-speed operation is also possible using the speed switch and on/
off switch DS 2/2 (Accessories).
NOTE!
The use of other brands, especially other electronic devices, can lead to malfunctioning and even destruction
of the controller or fan. Controllers which have not been cleared by Helios are not liable for warranty and gua-
rantee claims.
