ASSEMBLY/
INSTALLATION
2.4 Functional description
The GigaBox GB EC.. fans are steplessly speed-controllable by means of 0-10 V control voltage. Suitable
potentiometers (Type PU/A 10), three-step switches (Type SU/A) are offered in the Helios accessories range.
Stepless speed control is possible with the universal controller (Type EUR EC). Alternatively, the electronic differential
pressure/temperature controller EDR / ETR can be used.
m
Activation / deactivation:
EC fans can be frequently activated and deactivated via the 0-10 V control input or the release input
depending on the type. This is gentle on the electronics and ensures a long service life. Control via the power
supply (on/off) is not recommended. In general, there must be an interval of at least 120 seconds between
activation and deactivation.
m
In case of strong vibrations and/or odours, maintenance must be carried out by a specialist according to
chapter 1.4.
3.0 – Assembly
The EC-GigaBox model range allows a flexible
assembly (installation position horizontal or verti-
cal) by five possible axial and centrifugal dischar-
ge directions of the outlet adapter (see Fig.8).
Please pay attention to a secure, durable moun-
ting of the unit as well as a free access to the
terminal box and the motor impeller unity on the
rear of the unit. Easy positioning is made using
integrated crane hooks. Removable panels allow
an easy inspection access.
To prevent vibration transmission to buildings
and ducting systems use flexible connectors
GB-FM..(included in delivery) between EC-fan box and connecting ducting.
- With regard to duct installation, it must be ensured that there is a sufficiently long straight section of ducting
(2x duct diameter) before and after the unit, as otherwise there may be a loss of performance and higher
sound levels.
- The GigaBox must be assembled so that it is freely accessible for maintenance work.
- The installation must be carried out with condensation drainage showing downward (see Fig. 9)!
- The side panels can be removed for cleaning.
