EDUS39-605 InstallationInstallation of Outdoor Units 441-5 Electrical specifications (1)2. MAIN COMPONENTSFor main components and function of the main compo-nents, refer to the Engineering Data Book.3. SELECTION OF LOCATIONThis unit, both indoor and outdoor, is suitable for instal-lation in a commercial and light industrial environment. Ifinstalled as a household appliance it could cause electro-magnetic interference.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 locationin case it drips out the unit (e.g. in case of a blocked drainpipe).4. The piping length between the outdoor unit and the indoor unitmay not exceed the allowable piping length. See Section 6-3,Example of Connection on Page 49.5. 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 windwill disturb the operation of the unit. If necessary, use awindscreen 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. Refer to Section 9. CautionNOTEfor Refrigerant Leaks.• An inverter air conditioner may cause electronic noisegenerated from AM broadcasting. Examine where to in-stall the main air conditioner and electric wires, keepingproper distances away from stereo equipment, personalcomputers, etc.Refer to figure 2.1. indoor unit2. Branch switch, overcurrent breaker3. remote controller4. COOL / HEAT selector5. personal computer or radio• If the electric wave of AM broadcasting is particularlyweak, keep distances of 10 ft. or more and use conduittubes for power and transmission lines. In heavy snowfallareas, select an installation site where snow will not affectoperation of the unit.CAUTIONDo not install in the following locations.• Locations such as kitchens which contain a lot of min-eral oil or steam in the atmosphere or where oil maysplatter on the unit.Resin parts may deteriorate, causing the unit to fall orleak.• Locations where sulfurous acids and other corrosivegases may be present in the atmosphere.Copper piping and soldered joints may corrode, caus-ing refrigerant to leak.• Locations where equipment that produces electromag-netic waves is found.The electromagnetic waves may cause the control sys-tem to malfunction, preventing normal operation.4. INSPECTING AND HANDLING THE UNITAt 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:• Fragile, handle the unit with care.Keep the unit upright in order to avoid compressordamage.• Choose the path along which the unit is to be brought inahead of time.• If a forklift is to be used, pass the forklift arms through thelarge openings on the bottom of the unit.Model REYQ72/96MTJUREYQ144/168/192MTJUPower supplyPhase - 3~ 3~Frequency Hz 60 60Voltage V 208-230 208-230Voltage tolerance % ±10 ±10Recommended fuses A 60 60+60CompressorPhase - 3~ 3~Frequency Hz 60 60Voltage V 208-230 208-230Nominal running current A 10.1+13.1 (10.1+13.1)+(10.1+13.1)Model REYQ72/96MTJU REYQ144/168/192MTJUControl and fan motorTypeVoltage V 208-230 208-230_
