5 English3. SELECTION OF LOCATIONThis unit does not have specifications for outdoor installation. Theunit must be installed indoors (example: machine room, …).Paying attention to the conditions mentioned below, select the place forinstallation with a prior approval of customer.1. The foundation is strong enough to support the weight of the unit andthe floor is flat to prevent vibration and noise generation.2. Consider the space required for refrigerant piping work when install-ing. Refer to [Necessary Space].3. There is no danger of fire due to leakage of inflammable gas.4. The piping length between the outside unit and the indoor unit maynot exceed the allowable piping length. “9. REFRIGERANT PIPING”.5. Locations where the noise of the unit operating will not disturbnearby houses, etc.6. Locations with airflow and ventilation holes capable of dissipatingheat from the machine and where the ambient temperature aroundthe outside unit is between 35 and 95 °F and the humidity does notexceed 80%.[Necessary Space]When installing, secure the space mentioned below without fail.(Refer to figure 2)1. In case of a single installation [inch.]2. In case of series installations [inch.]3. Top view4. Side view5. Outside unit6. Service Space (front side)7. Service Space (back side)8. Space for installing water piping∗Secure a enough space for removing the front panel.9. Ventilation Space∗above the area ( ) of the outside unit.10. Secure spaces in the front, back and top sides as same asthe case of single installation.DANGER• Do not install unit in an area where flammable materials arepresent due to risk of explosion resulting in serious injury or death.• Refrigerant is heavier than air and replaces oxygen. A massive leakcould lead to oxygen depletion, especially in basements, and an as-phyxiation hazard could occur leading to serious injury or death. Re-fer to the chapter “Caution for refrigerant leaks”.NOTE1. An inverter air conditioner may cause electronic noise generatedfrom AM broadcasting. Examine where to install the main air con-ditioner and electric wires, keeping proper distances away fromstereo equipment, personal computers, etc.(Refer to figure 3)1. Indoor unit2. Branch switch, overcurrent breaker3. Remote controller4. Cool/heat selector5. Personal computer or radioIf the electric wave of AM broadcasting is particularly weak, keep dis-tances of 10 ft or more and use conduit tubes for power and trans-mission lines.2. Water qualityWater containing high level of foreign materials may cause thecorrosion of heat exchanger and piping or scale accumulation.Use water satisfying “7-4 Water quality”.3. Cooling towerUse a closed type cooling tower without fail. (Open type towercannot be used.)4. StrainerInstall the strainer (accessory) without fail at the inlet of water pip-ing. (If sands, wastes, rust particles, etc. are mixed in the water cir-culation system, damage to the plate type heat exchanger may becaused by the corrosion of metal materials and clogging of theheat exchanger.)WARNINGDo not install in the following locations.• Locations such as kitchens which contain a lot of mineral oil or steamin the atmosphere or where oil may splatter on the unit.Resin parts may deteriorate, causing the unit to fall or leak.• Locations where sulfurous acids and other corrosive gases may bepresent in the atmosphere.Copper piping and soldered joints may corrode, causing refrigerantto leak.• Locations where equipment that produces electromagnetic waves isfound.The electromagnetic waves may cause the control system to mal-function, preventing normal operation.4. INSPECTING AND HANDLING THE UNITAt delivery, the package should be checked and any damage should bereported immediately to the carrier claims agent.When handling the unit, take into account the following:1. Fragile, handle the unit with care.Keep the unit upright in order to avoid compressor damage.2. Choose the path along which the unit is to be brought in ahead oftime.3. In order to prevent any damage to the unit during installation, useslings (cloth) or patch plates and lift the unit referring to figure 4.4. Lift the unit preferably with a crane and 2 belts of at least 27 ft 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 center ofgravity.6. Be sure use the standard supplied accessories and dedicated partsas installation parts.(Refer to figure 4)1. Patch plates or clothes2. Belt slingNOTE• Use belt sling of 13/16” width or less which adequately bears theweight of the product.5. UNPACKING AND PLACING THE UNIT• Make sure the area around the machine drains properly by setting updrainage grooves around the foundation.• Make sure the unit is installed level on a sufficiently strong base toprevent vibration and noise.• Secure the unit to its base using foundation bolts. (Use four commer-cially available M12-type foundation bolts, nuts, and washers.)• The foundation bolts should be inserted 13/16”.• Fix 4 foundation bolts.• Support the unit with the foundation which islarger than the hatched area shown in figure 5.(Refer to figure 5)1. Front side2. Position of foundation bolts3. Hole for a foundation bolt(φ11/16 ida. holes at 4 corners)4. Avoid such a foundation where the unit is supported by4 corner points.CAUTION• When installing the unit closely contacting the wall for anyunavoidable reason, arrange so that no vibration from the unit maybe transmitted to the wall surface by insulating the vibration usingcushions, etc.13/16”
