Furthermore the electrical supply as well as external sensors or optional accessories such as duct
heaters etc. must be connected.
The remote operator control must be connected to the control system using the provided cable and
placed at the ventilation system or nearby. The electrical connection has to be made according to the
wiring diagram, see the additional operating manual control for the control system.
5.3 Connection of the ventilation ducts to the unit
The connection sleeves of the Rosenberg-SupraBox Comfort are provided as circular
tube spigots, with T-sealing lip sizes as shown in the unit drawings. The duct system
must be installed according to the valid technical standards and regulations and must
support the dead load by installations of the customer. Additional requirements
concerning sound insulation separate vibration isolation can be provided as elastic
connections. These are not standard in the scope of delivery, but offered as
accessories. The fresh air and exhaust air duct must be isolated against condensate water.

seal the tube of the maintenance pan by appropriate material (e.g. tape) in order to avoid a volume
flow leakage in this area.
Especially in the cold seasons there could be condensate in the exhaust air duct of the reverse flow
heat exchanger. In order to make sure the condensate drains correctly via the condensate pan and to
avoid air leakage, it is important to attach a vacuum trap as shown in the drawing below. Alternatively
a hose can be fixed at the unit to replace a trap. The minimum sizes must be observed by the
customer. Fill the trap with water before startup. Protect the trap against desiccation and in cold
