5.1 INDOOR UNIT POSITIONING The indoor unit should be positioned so as not to compromise suction and supply air. Models 21 - 28 must be installed with plug, nut and lock nut. Adjust the fastening and tilt towards the drain pipe to aid condensation water drainage. Figure 3 Models 91 - 101 are normally positioned on the floor. If the unit is installed on the ceiling, provide a system of brackets as shown on figure 4. The condensation water drainage connection is positioned on the bottom of the drain pan.

6. INSTALLATION 6.1 INSTALLATION CLEARANCES It is important that an adequate air volume is available at the intake and exhaust sides of the condenser coil. It is essential to avoid air recirculation between the intake and exhaust sides to prevent a reduction of the rated performance levels and unit operating problems. The minimum clearances required for satisfactory operation of the unit are reported in the dimensional drawings. 6.2 VIBRATION DAMPER MOUNTS (OPTIONAL) The unit should be installed on rubber or spring vibration damper mounts, supplied as an accessory, to reduce vibrations transmitted to the structure. The dimensional drawing, with floor plan enclosed with the machine, illustrates the position and load of each vibration damper. Anchoring procedures must be completed before positioning the machine on the ground; ensure that the lifted machine is fully secured to the lifting cables. 6.3 WATER PIPING CONNECTIONS Unit water pipework must be installed in accordance with national and local regulation and codes. Follow the recommendations below when designing the water piping circuit (refer to the diagrams included in this manual). – Piping should be connected to the unit with flexible joints, to avoid vibration transmission and allow for thermal expansion (the same procedure should be adopted for the circulating pumps). The following devices should be located on the piping system: – Shut-off valves, temperature and pressure gauges for routine unit maintenance and control operations – Thermowells on inlet and outlet pipes, if there are no temperature gauges fitted. – Shut-off valves (gate valves) to isolate the unit from the hydraulic circuit. – Mesh strainer (on inlet pipes), with mesh no larger than 1 mm, to prevent debris from entering the heat exchangers. – Vent valves, to be installed in the upper parts of the circuit, for air bleeding. – Expansion vessel and automatic filling valves for circuit pressurisation and thermal expansion compensation. – Drain cock and, where necessary, drain tank to allow system emptying for maintenance purpose or seasonal stops.
