1. GENERAL The DS air-conditioners include two separate units - Indoor and Outdoor Unit. The two units are interconnected by two refrigerant tubes and an electric cable. The DS indoor units can be supplied with right or left hand access for service and tube connection. Right/left hand sides are defined when looking at the unit from behind it (filter side). -

Page 7: Indoor Unit Installation
4. INDOOR INSTALLATION 4.1 Indoor Unit Location (See Figure 3) The indoor unit is designed for installation on a false ceiling or other compartment, where there is no influence from outdoor conditions. While selecting the location, the following conditions must be assured: a) The location should assure free flow of the return air into the unit without interference. - Page 8 Where the unit must be installed in an attic space or outside, the following conditions must be assured: a) The unit must be protected from rain, heat and radiation by an additional layer of 1” thick thermal insulation. b) The return-air duct should be as short as possible, with a minimum dimension of 700x300 mm (or similar cross section) with full acoustical lining inside, and no more than two long-radius elbows.

b. Serrated Rubber Mounting In sites where the spring isolators assemblies cannot be installed, mount the unit as show in Figure 6. Insert four 3/8” studs in the ceiling according to the dimensions of the suspension angle frame mounted on the unit. Prepare 30x30 mm, 1.5 mm thick galvanized sheet metal for each stud and assemble according to Figure 6. -

Page 12: Recomendation For Interconnecting Tubing Installation
Recommendation For Interconnection Tubing Installation Three possible versions are schematically illustrated: 1) The outdoor unit installed above the indoor unit (Figure 9) - such installation requires an oil trap in the suction line at the lowest point of the riser. The radius of the oil trap should be as short as possible (See Figure 10). -
Page 13: Setting In Operation
6.3 Setting in Operation WARNING This paragraph describes the necessary steps for setting the unit into operation; be sure to follow the instructions, to assure proper functioning of the air-conditioner. The outdoor unit is recharged with the correct amount of refrigerant. In extended runs, for additional refrigerant charge please refer to the outdoor unit name plate. - Page 14 CAUTION When performing the following steps, avoid any exposure to the service valve ports; remember that the system is under pressure g) Remove the valve caps from the three-way valves. Position both valves to “open” using an hexagonal wrench (See Figure 16). h) Replace valve caps of both three-way valves.

Page 17: Interconnecting Cable
Interconnecting cable The electrical cable must be one integral piece, without any joints. When installing the cable under the floor, it must be protected and isolated from any possible contact with water. When the cable path runs inside the wall or an acoustic ceiling, it will be protected with a fire-retardant tubing system. In addition, the two units should be interconnected by a telephone-type cable, 2 x 0.5 mm²... - Page 18 8.3.4 Display unit and master controller mounting 1. Main Control Board on Indoor Unit 2.
