Manufacturer catalogue image · Cassette family; reviewed dual-outlet panel

01 / UNDERSTAND THE EQUIPMENT

Coordinate the visible panel with the hidden terminal

Langri's dual-outlet cassette fan-coil page presents a visible ceiling panel with a broad central grille and opposed long discharge slots. The original image also shows a small central display/control area. The panel image is evidence of the room-facing construction; it does not show a complete suspended body, connection drawing, pump or control wiring. The official text names the dual-outlet offer but provides no rated thermal table.

Other gallery recommendations include cassette and eight-outlet descriptions. They are kept within one cassette family here because outlet names and photographs alone do not establish independently rated product systems. The practical decision is whether the selected panel/body can distribute conditioned air in the actual ceiling zone while leaving accessible water, drainage and electrical connections. This brief distinguishes a panel-layout observation from a proven airflow or performance result and lists the drawings and duty data needed to make a ceiling order reviewable.

Selection and application review

Match the panel and body as one ordered set

Request the exact body/panel part numbers, panel and ceiling-opening dimensions, support details and approved ceiling thickness. The visible front photograph cannot show whether every listed panel fits every fan-coil body. Ask which panel, controller and accessories are included in the quotation.

Coordinate suspension with the structure and reserve the instructed space for water valves, insulated joints, electrical enclosure and removable components. Do not use the panel width or a familiar nominal ceiling tile size as a dimensioned installation drawing.

Put the outlets where the occupied zone needs them

The dual-outlet image shows two opposing long slots around a central grille. Ask for discharge direction options, airflow at each speed and the relevant distribution/throw evidence. A named eight-outlet alternative is not automatically better for a narrow room, nor does the picture prove freedom from draughts.

Provide the ceiling height, partitions, occupancy positions and neighbouring return/supply arrangements. Select sensible and total cooling at the intended room-air and water conditions. If a discharge side must be closed or redirected, obtain the manufacturer's permitted configuration and corresponding performance rather than modifying the panel from an assumption.

Resolve the cooling drain within the ceiling

Ask for the actual drain outlet location, gravity or pump configuration, permitted pipe arrangement and any lift limitation. Agree access to the drain pan, pump if supplied and fault-sensing components. None of these internal details can be established from a front-panel image.

Before the ceiling is handed over, require the agreed drain test and water-connection checks for the installed arrangement. Specify the control response to drain trouble if that function is included. Do not promise leak prevention or unattended safety on the basis of a cassette label.

Review thermal, electrical and maintenance evidence together

Obtain a selected cooling/heating table with air/water conditions, flow, pressure drop, fan input and sound basis. Match the control/wiring schedule to the actual small panel display and external thermostat requirements; the picture does not prove communication capability or valve control.

Agree filter cleaning from the room side and access for motor, coil, electrical and drain servicing. Current selected-model ratings, price, delivery and independent installed results are unknown. The output of this brief is a coherent ceiling coordination request, with appearance variants consolidated rather than presented as artificial product pages.
