INSTALLATION Wall Mounted 0121…0661 A D Q.E. B B C C WMF 0551-0661 Fig. 2 TOP FRONT PANEL (A) The Top Front Panel is fixed with two screws; to remove: - release the bolts; - hold edges of upper panel and pull; - raise the panel to remove. This operation gives access to the airfilter; free-cooling damper, damper motor and electrical panel. Access to the radial fan and the pre-heat electrical resistors is only possible once the internal sheet is removed (D).
INSTALLATION Wall Mounted 0121…0661 TRANSPORT AND MOVEMENT The unit should not be turned on its back or upside-down, or exposed to the weather and should be taken as near as possible to the installation location before removing the cardboard packing and the pallet. The unit can be lifted: - with a fork-lift, placing the forks in the appropriate slots of the pallet; - with straps passed under the unit, making sure that they do not put pressure on the upper rim of the unit.

However, it is recommended to protect the unit from rain, snow or water falling from drains or gutters.
INSTALLATION Wall Mounted 0121…0661 To facilitate maintenance, leave at least 1,5m free space in front of the unit as shown in the diagram (point E). This minimum distance allows the expulsion of external air for condensation and the aspiration of air for free-cooling. N.B.:Side access to the unit is only necessary on the right side of models 0121…0331 for the replacing of the damper servomotor; it is not necessary for other maintenance operations or access to electrical panels and wires.

INSTALLATION Wall Mounted 0121…0661 Fix rubber seals around the mouths of the air intake and discharge to ensure an airtight fit; 18-20mm thick selfadhesive closed-cell neoprene rubber tape is recommended. Apply a layer of builder’s silicone to the joint between the top cover of the unit and the wall, to prevent rain from entering the gap. SILICONE SEALANT NEOPRENE TAPE Fig.
INSTALLATION Wall Mounted 0121…0661 MOUNTING THE UNIT WM units are mounted on the outside wall of the air conditioned environment and fixed using screws through the two side flanges. Before installing the unit observe the following instructions: 1. Check that the wall is of suitable material and strength to support the weight of the unit and to cope with the (relatively minimal) vibrations of the refrigerant compressor; 2. Make intake and discharge holes in wall (see par. 'AIR DISTRIBUTION'; 3.
