42VMC Installation Vertical wall-mounting Hole Plate Template • The preferred arrangement is generally under a window sill on an external wall. This makes it easier to install the interconnecting tubing, electrical connections and condensate pipework to the outdoor unit. The indoor unit can also be installed against an internal partition if the connections to the outdoor unit can be concealed.
42VMC Installation ENGLISH Drilling the hole in the wall for the connection of the pipes For horizontal installation To allow the condensate drain pipe to correctly come out of the unit, proceed as follows: 75 mm Ø 80 mm 50 mm 햲 Ø 70 / 80 mm 5-10 mm The pipes can exit the unit to three different directions (see illustration). For exit to the rear, the wall hole must be made in the position shown in the illustration.
42VMC Refrigerant connections Make refrigerant connections before connecting the system to the power supply. Refer to the outdoor unit installation manual for tube sizing, and limitations (slopes, length, number of curves allowed, refrigerant charge, etc.) Model mm 009 012 014 018 024 9.52 12.70 12.70 12.70 12.70 Connection to the unit Insufficient tightening torque will cause gas leaks.
