5. General Installation Instructions
5.1 Installation of the unit
The Rosenberg-SupraBox Comfort overhead version must be installed on a ceiling which is professionally constructed and statically suitable for this specific use.
Assumption of static or dynamic building functions by Rosenberg devices must be excluded. Otherwise the warranty by Rosenberg Ventilatoren GmbH will expire for damages to the device or resulting damages to the building.
Installation and assembly may only be made by trained staff, familiar with the specific accident prevention regulations and general safety-related and occupational health laws.
In addition to the static analysis for the overhead construction also consider the following instructions:
The suspension must be level and without torsion.
The horizontal inclination angle of the device may not exceed a maximum of 2%.
Choose an installation space with an unobstructed condensate drain and water trap, as well
as a sufficient gradient of the condensate line.
The height level between installation space and the floor/intermediate ceiling must guarantee a professional condensate drain from the functional parts. Consider the height of the waste trap!
In order to ensure low noise operation consider the following advice:
Low air velocity in the duct
Do not install the device on a wooden ceiling
Use a vibration resistant ceiling construction

sound insulation can be met by separate vibration isolation with elastic connections. These are usually not included in the delivery, but can be provided as additional equipment. The external air and exhaust air duct must be protected against condensate water.
5.4 Electric Installation
The electric connection must be exclusively made by a licensed electrician according to the VDE-regulations. The connection must be made exactly according to the wire diagram and face plan. Check all screw joints before startup of the unit and if necessary retighten them. Further installation information can be found in the separate operating manual of the control system.
5.5 Connection of the condensate, exhaust air and overflow pipes
The Suprabox is equipped with a condensate pan including an all-side gradient in the exhaust air. The condensate drain consists of an aluminium circular tube of 15 x 2 mm. To ensure that the exhaust air maintenance door can be opened, we recommend an appropriate flexible hose with a circular cuff for connection. 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. Alternatively a hose can be fixed at the unit to replace a trap. The minimum size must be observed by the customer. Fill the trap with water before startup. Protect the trap against desiccation and in cold areas against frost. Do not connect the spout to the sewage system. Alternatively a vacuum trap with non-return ball can be used but make sure that there is a suction lift of at least 70 mm.

7.6 Panel filters
7.6.1 Startup
Before installation of the filter all seals should be checked for correct fit. Clean the housing floor.
Pay attention to the directional arrow for the air stream printed on the panel filters.
The filter will be controlled by a differential pressure sensor. If the admissible differential pressure is exceeded, a signal will appear on the control panel to change the filter. In this case the filters must be changed immediately. More information can be found in the manual of the control system.
7.6.2 Operation
The panel filters will be fastened at the assembly frame with a tensioning angle rail. Draw the angle rail to the body in order to change the filter and remove it afterwards. Pay attention to the correct fit of the filter at the frame after the re-assembly. During the filter change check the seal and replace it if necessary.
7.6.3 Maintenance and Cleaning
The recommended final resistance for this filter version is 150 PA. Always replace panel filters completely. The filters can be fully incinerated and must be disposed of accordingly. Clean the housing bottom before installing the new filter.
Change the filter after 12 months of operation or down time at the latest. Note the
filter change with name and date at the unit and in the maintenance book.
