– Assembly

The EC-GigaBox model range allows a flexible
assembly by three possible centrifugal discharge
directions of the discharge adapter (see Fig.8).
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 connectors (included in delivery) bet-
ween EC-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!
- Removable panels allow cleaning access on all sides .
– 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 insulated ducts, which can run then into the fan. Therefore drainage of condensation water must be ensured.
Depending on the installation postion, use and event. condensation water, the condensate collector GB-KW.. (acces-
sories) is to be used.
– Condensate collector for condensate drainage (accessories)
The collected condensation water in the condensate collector is led away over the condensate drainage (Fig.9).
Therefore a gradient of minimum 1° must be considered and a connection to the local drainage system (provided by
customer) must be quaranteed.
