Transport & Storage
Dry indoor conditions with a temperature range of -40°C to +50°C.
Installation, Maintenance & Operation
Information about installation, maintenance and operation is available in the document “UserManual_OPTIMA-RES-A”.
OPTIMA-RES-A is mounted on the wall or ceiling and is connected to a spiro duct by a rubber gasket tight connection.
The system box can be xed to the wall or ceiling by screws through the holes in four mounting ears on the bottom
plate. The electrical connection terminals and VAV controllers can be found under the cover of the system box. The
cover can be removed by turning the two locks on the cover plate with a screw driver by 90°. To avoid falling out
after unlock the cover plate is tight to the system box by chains. The cover plate in the closed position is sunken into
the frame. This enables to attach a plaster board to the outer surface of the cover. So the inspection opening cover
can be from the same material and ush with the surrounding wall or ceiling where the system box is installed. The
plaster board for the cover must be foreseen with cut-outs to keep the cover locks accessible.
The power supply and signal cables can be pulled into the box through the diaphragm between the supply/extract
air connections. The cables must be xed inside the box on the xing ridge by cable straps. This avoids excessive
mechanical stress on the cables. The cables shall be connected to the spring terminals according to the wiring
diagram. To protect the circuitry from overload or short circuit fault, there is a fuse terminal on the power supply.
Dry indoor conditions with an operation temperature range of -20°C to +70°C.
