Centrifugal fans – GigaBox GBW../GBD.. T120
3.0

– Assembly

The GigaBox T120 model range allows a flexible
assembly by three possible centrifugal discharge
directions of the discharge adapter (see Fig.5).
Please pay attention to a secure, durable moun-
ting of the unit as well as a free access to the ter-
minal box and the motor impeller unity on the rear
of the unit. Easy positioning is made using inte-
grated crane hooks. Removable panels allow an
easy inspection access.
To prevent vibration transmission to buildings and ducting systems use flexible connections (included in delivery) bet-
ween fan box and connecting ducting.
- To achieve the given sound and power data, it is necessary when connecting the fan box to a ducting system
to have at least twice the duct diameter of straight ducting before and after the fan box. Otherwise there
may be a loss of performance and higher sound levels.
- The GigaBox must be assembled so that service and maintenance can be performed easily and safely (back
side of the motor).
- The installation must be carried out with condensation drainage showing downward!
- The cleaning is carried out via the lateral inspection access (see Fig.6).
- Condensate formation
Condensate formation in the unit is nearly impossible by double-skinned thermal insulated panels. Nevertheless, on
condensate formation must be calculated with very humid media or steam-containing air. Condensate forms, above all,
in not isolated ducts, which can run, then into the fan.
3.1

Installation

The fans are delivered in series as a complete unity, i.e. ready to install. With a raised installation position (not at ground
level) the unit must be well secured to prevent any movement. Here the wall brackets GB-WK.. (accessoies) is to be
used. For protected installation outdoors, the outdoor cover hood GB-WSD.. (accessories) and the rain drainage GB-
RA (accessories) must be mounted. With installation on a level surface put anti vibration mounts SDD-U (accessories)
under each corner between casing and surface to avoid vibration transmission.
Pay attention to the correct arrangement on the assembly of the discharge adapter (see Fig. 5).

Dismantling

The complete motor impeller unity is without disassembly of the remaining unit components to the rear side removable.
3.3

Electrical connection

The following checks are to be carried out:
- Check for operation according to the intended purpose of the fan
- All work must be carried out with the equipment fully isolated from the power supply.
The electrical connection is to be carried out in accordance with the relevant wiring diagram and is only to be
done by a certified electrician.
All relevant safety regulation, national standards and norms are to be adhered to.

Cleaning and Maintenance

The cover with handle of the inspection access is simply removable for the cleaning and maintenance (see Fig. 7).
- Make sure before the cleaning that the unit is isolated from the mains and is secured against restarting with an
isolator switch!
- Clean unit only with a damp cloth.
- Excessive deposit of dirt, dust, grease and other materials on the impeller, motor and between casing and impeller is
to be avoided and has to be prevented by periodical cleansing.
- For maintenance purposes inspection doors and access openings must be provided in the duct system in a suitable
place.
- The motors have maintenance-free, long lasting, greased ball bearings.
