Xpelair Fig. 3 CHAP. 2.3 INSTALLATION OF THE UNIT 2.3.1 Drilling the wall This operation should be carried out using the propertools to facilitate your work and prevent excess damage or disturbance to your client. The best tools for drilling large holes in walls are special drills called core borers with very high twisting torque and adjustable rotation speed depending on the diameter of the hole to be drilled. To prevent the creation of large amounts of dust and rubble due to drilling, the core borer can be fitted with a vacuum system applied by means of suction cups to the drilling zone. Core drills and accessories are available from tool suppliers to the construction industry. To drill the holes, proceed as follows: Fasten the drilling template to the wall leaving the necessary space from the ceiling, floor and side walls as shown on the template. Use adhesive tape to fasten it in place. Use a small drill or punch to mark, with extreme care, the exact centre of each of the holes to be drilled. Using a core boring head measuring at least 152 mm to drill the two holes for entry and exit of the air. Note: The holes should have a slight downward inclination to prevent any backflow of water from the pipes (see fig. 5). Most of the removed material is expelled outwards, therefore make sure that it does not hit any person or object when it falls out. In order to avoid as much as possible outer plaster breaking, it is necessary to proceed carefully with the last part of hole execution, decreasing pressure on core borers. digitemp Fig. 5 Xpelair Next, drill the holes for anchoring the fastening brackets to the wall using as a first option the 4 holes on the ends of the bracket as shown on the drilling template (see fig. 6). If the wall is not very solid, it is advisable to use some extra anchor bolts. As you can see, the bracket can be fastened in a number of different ways and positions. The air conditioner is heavier on the left-hand side, so it is best to make sure of a solid anchorage on that side. The anchor bolts provided require holes with a diameter of 10 mm. In any case, the wall should be inspected carefully to determine the best possible anchorage and type of bolts suitable for particular situations. Warning: The manufacturer is not liable in case of underestimation of the structural consistency of the anchorage made at the time of installation. We therefore recommend that you perform this operation with the maximum care as, if not done properly, it can cause serious damage to persons and property. When installing models equipped with heating pump, if no drainage well for condensate has been provided built into the wall (see paragraph 2,3,2), it will be necessary, to allow for drainage of the condensate, to drill a hole through the wall measuring 16 mm in diameter in the position shown on the template (see fig.6). digitemp 2.3.2 Provision for draining condensate for machines with heat pump. When the machine is heating, it produces condensate that has to be drained through a specific drain line, otherwise the machine will not work. Drainage occurs by gravity. For this reason, it is essential for the drain line to have a minimum inclination of at least 3% throughout its length. The pipe can be rigid or not, with a minimum internal diameter of 16 mm. If the line drains into a sewer system, it should be provided with a trap ahead of the main outlet. The trap should be at least 300 mm lower than the inlet opening on the air conditioner (fig. 7). If the drainpipe drains into a vessel (tank or other container), this container should not be sealed and the drainpipe should not remain immersed in the water (see fig. 8). The correct position for the pipe inlet on the machine is shown on the template for drilling and positioning the machine (see also fig. 6). The air conditioner is equipped with a pipe with an external diameter of 14 mm for drainage of condensate. This pipe protrudes from the machine fora length of about 400 mm. The pipe should be fitted inside the one provided by you fora distance of at least 200 mm, without any sharp bends that could obstruct it. When draining toward the outside, the pipe can be inserted through the wall (always making sure to give it a suitable Inclination) (see fig. 5). Caution: make sure, in this case, that the water expelled outward does not damage or disturb persons or property. During the winter this type of drainage may cause sheets of ice to form. 2.3.3 After drilling the holes, the plastic pipes supplied with the Installation of air air conditioner have to be fitted through them. The pipe pipes and with insulation on the inside has to be fitted in the right-external hand hole with the insulated part toward the in...
