[. . . ] · Tilt the lower part of the indoor unit forwards and insert a spacer (e. g. a piece of wood) between the mounting plate and the unit (see Figure 9. 8) to allow access to the unit connections. 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. Fig. Legend 1 Exit for right piping 2 Exit for indoor piping 3 Securing with adhesive tape 4 Exit for left piping · Connect the coolant pipes from the outdoor unit and the condensed water hose to the installation drain. · Insulate the coolant piping and joints correctly and separately. 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 for warranty repairs. Fig. Legend 1 Heat-resistant material 2 Drain pipe 3 Insulated refrigeration pipes 4 Piping support plate 5 Interconnecting electric cable Danger of personal injury and material damage from explosion!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). · For pipework exiting from the right hand side and bottom of the unit extend the pipework through the relevant knock out before hanging unit (see section 9. 3. 6). · For pipework exiting from the left of the unit, make the connections at the rear of the unit first before hanging the unit (see section 9. 3. 6). 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). · Securely hang the indoor unit body onto the upper notches of the mounting plate. [. . . ] If the service manifold gauge is not capable of measuring to these pressures a separate Torr vacuum gauge should be fitted in line to measure this pressure. Warning!Ensure that the service valves on the outdoor unit remain closed during the evacuation procedure. 12. 3 Start Up Fig. 12. 3 Low pressure manometer reading with the low valve open and vacuum pump operational. Fig. Legend 1 Two-way valve 2 Allen key to open valves · Close the valves on the service manifold and disconnect the vacuum pump. [. . . ]
