Return Air Door Grill. 7. Return Air Intake Grill. 8. Control Unit. 9. Inter-Unit Piping and Wiring. 7.4.1 Indoor and Outdoor Unit Location The indoor and outdoor units should be installed as close to each other as possible. Do not exceed the tubing length and height differences as shown in the accompanying table. See Fig.
PAGE 51
7.5 Installing the Outdoor Unit • • • • • • • • • • Make sure to leave sufficient space around the unit. See figure 7-4 for minimum required distance between the unit and nearby walls. Install the unit in a location with convenient access for service and maintenance purposes. Protect the unit from any heat source. Prevent from any dust or strong wind installation sites. Position the unit in such a way to minimize motor noise which reaches the user and neighbors. The unit must be installed at least 5 cm.

7.6 Installing the Indoor Unit AB SOR BTION CUSHION AB SOR BTION CUSHION LONG C EILING ANC HOR S LONG C EILING ANC HOR S Fig. 7-5 • • • • • Overall and duct connecting dimensions are shown in the technical data tables. Allow free access to the service door, air filter and control box. Carefully plan the drainage tube path at a minimum slope of 2% avoiding sharp bends or oil traps. The indoor unit may be installed either hanging from the ceiling or resting on hard surface (i.e. concrete).
PAGE 53
7.6.3 Drilling a Hole in the Wall for Drainage and Inter-Unit Connections • • • • To make the connections between the indoor and outdoor units, a 70 mm hole should be drilled for the refrigerant lines, drainage hose and electrical cable passage, through the wall, as shown in Figure 7-6. Make sure to drill outwards and downwards, so that the opening in the outside wall is at least 10 mm lower than the opening on the inside. Route the drainage hose at the bottom of the hole.
PAGE 54
7.8 Connecting the Drain Hose Connect the rubber syphon to the drain hose connection. See Fig. 7-8 for details. Fig. 7-8 7.9 Connecting the Refrigerant Lines and Refrigerant Charge 7.9.1 Connecting the Refrigerant Lines • • • • • • Use tubing sizes according to the following table. To connect the refrigerant lines use only "L" type sealed, dehydrated copper refrigerant tubing. No other type may be used. The use of other types of tubing will void the manufacturer's warranty.
PAGE 55
7.9.2 Flaring and Connecting • • • • • Remove the protecting cap from the flare fitting. Remove the protecting cap from the tubing and cut to the required length. Make sure that the cut is perpendicular and clean, without burrs. Slip the flare nut on the tubing and flare the tube end, using standard flaring tools. Tighten the nut until resistance is met. Using a suitable wrench, tighten an additional 1/4 turn. Use the following specified torque, according to connection size. See illustration in Fig.7-9.

PAGE 58
8.2 Installing the Wall Mounted Units and the Remote Control • • • • • Remove all control components from their packaging. Place the control box on the indoor unit service door, or up to 1.5 m. from the unit. The box should be conveniently located for access by service personnel. Protect both the control box and the electrical connections from water and high humidity. Install the in-room wall mounted units.

8.5 Wiring the Outdoor Unit • • • • • • • Locate the terminal box cover according to the following figures. Remove the outdoor unit side cover. Connect the wires to the terminals, in accordance with the color coding and the suitable wiring diagrams. Connect the outdoor sensor cable, making sure the connector is properly inserted. Secure the inter-unit electrical cable to the outdoor unit using the clamps. Make sure that all screws and wires are properly fastened.

8.6.2 Indoor Unit Terminal Box CUE-1000A…1400A BROWN 8.7 Finishing the Job • • • • • • Hide the tubing wherever possible. Make sure that the drainage tube slopes downstream along its entire length. Insulate tubing connections with insulation materials. Fasten tubes to the outside wall. Seal the hole through which the cables and tubing are passing. Connect the air conditioner to the power source. Check all air conditioning operating modes. Consult the user manual. 8.7.
