Installation EDUS39-60522 Installation2. MAIN COMPONENTSFor main components and function of the main components,refer to the Engineering Data Book.3. SELECTION OF LOCATIONThis unit, both indoor and outdoor, is suitable for installation ina commercial and light industrial environment. If installed asa household appliance it could cause electromagneticinterference.The VRV OUTDOOR units should be installed in a locationthat meets the following requirements:1. The foundation is strong enough to support the weight ofthe unit and the floor is flat to prevent vibration and noisegeneration.2. The space around the unit is adequate for servicing and theminimum space for air inlet and air outlet is available.Refer to Figure 1, and choose a Pattern.1. Front side2. No limit to wall height3. Suction side3. Ensure that water cannot cause any damage to the locationby dripping out of the unit, such as from a blocked drainpipe.4. The piping length between the outdoor unit and the indoor unitmay not exceed the allowable piping length.See Section 6.3Example of Connection.5. Select the location of the unit in such a way that neither thedischarged air nor the sound generated by the unit disturbanyone.6. Make sure that the air inlet and outlet of the unit are notpositioned towards the main wind direction. Frontal winddisturbs the operation of the unit. If necessary, use a wind-screen to block the wind.DANGER• Do not install unit in an area where flammable materialsare present due to risk of explosion resulting in serious in-jury or death.• Refrigerant is heavier than air and replaces oxygen. Amassive leak could lead to oxygen depletion, especially inbasements, and an asphyxiation hazard could occur lead-ing to serious injury or death.NOTE1. An inverter air conditioner may cause electronic noisegenerated from AM broadcasting. Examine where toinstall the main air conditioner and electric wires, keep-ing proper distances away from stereo equipment, per-sonal computers, and other electronic devices.1. Refer to Figure 2. indoor unit2. Branch switch, overcurrent breaker3. remote controller4. COOL/HEAT selector5. personal computer or radioIf the electric wave of AM broadcasting is particularlystrong , keep distances of 10 ft. or more and use con-duit tubes for power and transmission lines.2. In heavy snowfall areas, select an installation site wheresnow will not affect operation of the unit.WARNINGDo not install in the following locations:• Kitchens containing a lot of mineral oil or steam in theatmosphere, or where oil may splatter on the unit.Resin parts may deteriorate, causing the unit to fall or leak.• Where sulfurous acids and other corrosive gases may bepresent in the atmosphere.Copper piping and soldered joints may corrode, causingrefrigerant to leak.• Where equipment produces electromagnetic waves.The electromagnetic waves may cause the control systemto malfunction, preventing normal operation.4. INSPECTING AND HANDLING THEUNITAt delivery, the package should be checked and any dam-age should be reported immediately to the carrier claimsagent.When handling the unit, take into account the following:1. Fragile, handle the unit with care.Keep the unit upright in order to avoid compressordamage.2. Choose the path along which the unit is to be brought inahead of time.3. If a forklift it to be used, pass the forklift arms through thelarge openings on the bottom of the unit.4. Lift the unit preferably with a crane and 2 belts of at least 27ft. long.5. When lifting the unit with a crane, always use protectors to preventbelt damage and pay attention to the position of the unit’s centerof gravity.6. After installation, remove the transport clasps attached tothe large openings.7. Bring the unit as close to its final installation position in itsoriginal package to prevent damage during transport.Refer to Figure 3.1. Packaging material2. Forklift3. Belt sling4. Wear plate5.
