40 GKX Installation ENGLISH Prior to installation g g g Threaded hangers k "T" bar (to be removed) k It is advisable to place the unit as close as possible to the installation site before removing it from the packaging. The grille panel and the remote control are separately packed for maximum protection. First position the refrigerant lines, as described in the chapter “Refrigerant connections”. Remove the “T” bar in order to facilitate installation operations.
40 GKX Installation a Indoors b Outdoors a Frame support brackets Making the hole for connection pipes in the external wall Installation of grille/frame assembly • After positioning the units and determining the connection position, make a 70 mm Ø hole in the wall. The same hole can be used as a condensate drain pipe conduit. Carefully unpack the assembly and check for damage sustained in transport. Attach the assembly to the unit by using the two hooks.
40 GKX Refrigerant connections ENGLISH IMPORTANT: During the unit installation make first refrigerant connections and then electrical connections. If unit is uninstalled first disconnect electrical cables, then refrigerant connections. Refer to the outdoor unit installation manual for tube sizing, and limitations (slope, length, number of curves allowed, refrigerant charge, etc.). Pipe connection to the unit Use two wrenches to tighten all connections.
