Centrifugal fans – GigaBox GBW EC.. / GBD EC..
Fig.9
– Condensate formation
Condensate formation in the unit is almost impossible due to the double-walled thermally insulated panels. Never-
theless, condensate formation can be expected in case of very humid media or moisture-containing air. Above all,
condensate forms in non-insulated ducts, which can then run into the fan. Therefore, the drainage of condensate must
be ensured. Depending on the installation position, use and potential quantity of condensation water, the condensate
collector GB-KW.. (accessories) is to be used.
– Condensate collector for condensate drainage (accessories)
The collected condensation water in the condensate collector is removed via the condensate drainage (Fig.9).
In this respect, a minimum gradient of 1° must be considered and a connection to the local drainage system (provided
by customer) must be quaranteed.
m The condensate collector must only be installed in a horizontal position!
3.1 Installation
The fans are delivered as complete units as standard, i.e. ready to install. In case of a raised installation position (not
at ground level), the unit must be well secured to prevent any movement. In this respect, the wall brackets GB-WK..
(accessories) are to be used. In case of protected installation outdoors, the outdoor cover hood GB-WSD.. (accesso-
ries) or the external weather louvre GB-WSG.. (accessories) must be mounted.
In case of installation on a level surface, anti vibration mounts SDD-U (accessories) should be placed under each corner
between the casing and surface to avoid vibration transmission. Pay attention to the correct alignment when assem-
bling the outlet adapter.

Dismantling

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

Electrical connection

The following checks are to be carried out:
– Check the intended purpose of the fan!
– The series must not be operated in potentially hazardous atmospheres!
– All maintenance and installation 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 carried out by a certified electrician. All relevant standards, safety regulations (e.g. DIN VDE 0100) and
the technical connection regulations of the energy supply companies must be observed.
– The connection to a low voltage network must be carried out according to DIN VDE 0298-4. Assignment of conduc-
tor cross-sections and the required fuse protection (excluding wiring protection, no device protection).
If a residual current circuit breaker is installed in the supply line of the EC fan, the residual current circuit breaker must
have the following technical characteristics:
Type B or B+ with a rated differential current of 30 mA.
The EC fan has a leakage current of <= 3.5 mA, calculated according to DIN EN 50178 Image 4.
The EC fan is exclusively designed for fixed connection, the connection via plug is not permitted.

Initial commissioning

The following checks must be carried out before initial commissioning:
- Check if installation and electrical connection is carried out professionally.
- Continuous protective conductor is present
- Attach controller e.g.: PU 10
- Check if safety equipment is mounted professionally.
- Outlet adapter must be installed correctly (Fig.6) (turned by 180° on delivery)
- Accessories (flexible connectors, strap etc..) must be taken out of the unit
