[. . . ] · Tilt the lower part of the indoor unit forwards and insert an auxiliary tool (e. g. a piece of wood) between the mounting plate and the unit (see Figure 9. 8) to allow access to the unit connections. 025 /035 Installation plate 120mm or more to wall 790 mm Right refrigerant pipe hole Ø 65 Fig. 9. 1 Dimensions of the hole for the piping. · Case B: Running the pipework out of either side or the bottom of the unit. In this case holes do not have to made in the wall since the indoor unit body has knock outs which can be opened to allow the pipes to exit the unit: choose the most convenient one for the desired outlet position (see Figure 9. 7). · Carefully break the knock out in the casing using pliers.

To do so, cover any possible cuts with masking tape or insulate any bare coolant piping with the corresponding insulation material suitable for air conditioning installations (for connection of the electrical wiring see section 11). 12 Split Type Installation Manual Installation of the indoor unit 9 Installation of the outdoor unit 10 10 Installation of the Outdoor Unit 10. 1 Selecting the Assembly Location Warning!Outdoor units must be placed in accessible areas for subsequent maintenance and repair operations. Vaillant will not be responsible for any costs derived from incorrect positioning that prevents easy access. Install the unit away from inflammable gasses or liquids or easily combustible substances and free from thick dust formation. Ensure that the ground is smooth and level and can withstand the weight of the outdoor unit. - The outdoor unit can only be mounted outdoors, never inside a building. - Do not install the unit in such a way that the air discharge affects the air inlets of premises nearby. - Ensure that there is sufficient space to observe the minimum distances (see Figure 8. 1). - Comply with local regulations: there are considerable differences dependant on the area. - Leave enough space to fit the condensed water drainage pipe (see section 10. 4).

The flare connections should be, where possible, accessible to allow leak test and future access. 9. 3. 6 Installation of the Indoor Unit Body · Check that the installation has been carried out correctly and that there are no leaks (see section 12. 1). [. . . ] · Do not continue to the next step until the pressure test has been successfully completed. 12. 2 Evacuating the installation Legend 1 Suction valve (gas) 2 Return valve (liquid) 3 Service manifold 4 Non-return joint 5 Gauge lines 6 Vacuum pump suitable for refrigeration systems · Connect a service manifold to the three-way valve on the gas line of the outdoor unit. · Connect a vacuum pump to the charging connection of the service manifold. · Turn the vacuum pump on and open the service manifold shut off valve to open the system to the vacuum pump · Ensure that all other valves are closed. · Leave the vacuum pump functioning for approximately 15 minutes (depending on the size of the installation) to carry out the vacuum.
