MOUNTING THE INSTALLATION PLATE AND DRILLING HOLES FOR PIPING.

6.1 Mounting the installation plate of the indoor unit.

WARNING
Use a detector before drilling the holes in the wall to detect power cables and piping in the wall
to avoid unnecessary damaging the wall and to avoid dangerous situations. note
a. Position the installation plate  level and on a sufficiently firm wall and leave a free space around
the installation plate. See Figure 8.
b. If the wall is made of bricks, concrete or a similar material, eight holes with a diameter of 5 mm have
to be drilled in the wall. Insert the plugs  for the respective mounting screws  in the wall.
c. Mount the installation plate  on the wall with eight type "A" screws .
G
NOTE
Mount the installation plate and drill wholes in the wall according the material in which the wall
is build and the respective attachment points on the installation plate. (dimensions are in "mm"
unless indicated otherwise).

Drilling holes for piping, condensed water hose and power cable.

a. Determine the position of the hole according the diagram in Fig. 9. Drill a hole with a diameter ≥ 65
mm, directed slightly down in the direction of the outdoor unit; this will prevent water seeping inside
(Fig. 10).
b. Always use a drilling gauge for drilling in metal gratings, metal sheets or similar materials.

CONNECTING THE REFRIGERANT PIPING

7.1 Connecting the refrigerant piping
a. Provide the pipe ends with a flare with swivel or similar screw connection.
b. Inner part: Secure the swivel nut manually to the piping of the indoor unit and secure the swivel nut
with an open-end wrench and a torque wrench as shown in Fig. 13.
c. Outer part: Secure the swivel nut manually to the fittings on the valves of the outdoor unit and
secure the swivel nut with an open-end wrench and a torque wrench as shown in Fig. 13.
