Find the space for the installation of the return air grille and mark the opening to do. Cut the falseceiling. (fig. 2-2)

Use rawl plug suitable to the ceiling consistence and four M10 threaded bars of suitable length (not supplied). (fig. 2- 3)

Mark on the ceiling the holes for the hanging rods, verify the distance of the centres. The value included in the brackets is referred to the model X18. (fig. 2-4)

Drill a 80 mm diameter hole, for the passage of refrigeration pipework, condensate pipework and electrical cable. Insert a PVC pipe in the wall. (fig. 2-5)

Secure the unit in position with locknuts and washers, level the unit, keeping the right distance from the falseceiling for the installation of return air grille. (fig. 2-6)

Foresee a removable panel of the falseceiling for servicing. (fig. 2-7)

The unit is supplied with PVC hose from the condensate pump. Maximum pump lift is 250 mm over the unit. Convoy the condensate with a positive slope (min. 1:100) to the out- side. The highest point in the condensate pipework should be as close to the unit as possible. This prevents a large volume of water draining back into the unit when it is switched off. (fig. 2-8)

Convoy the condensate to the outside with a positive slope, from a trap at the end if necessary. (fig. 2-9)
