3 About the boxInstallation manual8RXS50+60 + RX50+60 + ARXS50~71R410A split series3P360062-1H – 2016.09WARNING▪ ONLY use copper wires.▪ Make sure the field wiring complies with the applicablelegislation.▪ All field wiring must be performed in accordance withthe wiring diagram supplied with the product.▪ NEVER squeeze bundled cables and make sure theydo not come in contact with the piping and sharpedges. Make sure no external pressure is applied to theterminal connections.▪ Make sure to install earth wiring. Do NOT earth the unitto a utility pipe, surge absorber, or telephone earth.Incomplete earth may cause electrical shock.▪ Make sure to use a dedicated power circuit. NEVERuse a power supply shared by another appliance.▪ Make sure to install the required fuses or circuitbreakers.▪ Make sure to install an earth leakage protector. Failureto do so may cause electric shock or fire.▪ When installing the earth leakage protector, make sureit is compatible with the inverter (resistant to highfrequency electric noise) to avoid unnecessary openingof the earth leakage protector.WARNINGIf the supply cord is damaged, it must be replaced by themanufacturer, its service agent or similarly qualifiedpersons in order to avoid a hazard.3 About the box3.1 Outdoor unit3.1.1 To remove the accessories from theoutdoor unita db c1× 1× 1× 1×a Outdoor unit installation manualb Fluorinated greenhouse gases labelc Multilingual fluorinated greenhouse gases labeld Drain plug (located at bottom of packing case)4 Preparation4.1 Preparing installation site▪ Choose the installation location with sufficient place for carryingthe unit in and out of the site.▪ Choose a location where the hot/cold air discharged from the unitor the operation noise, will NOT disturb anyone.▪ Sound sensitive areas (e.g. near a bedroom and the like), so thatthe operation noise will cause no trouble.▪ Provide sufficient space around the unit for servicing and aircirculation.▪ Avoid areas where flammable gas or product might leak.Install power cables at least 1 metre away from televisions or radiosto prevent interference. Depending on the radio waves, a distance of3 metre may not be sufficient.WARNINGDo NOT place objects below the indoor and/or outdoor unitthat may get wet. In this condition, condensation on themain unit or refrigerant pipes, air filter dirt or drain blockagemay cause dripping. This results in fouling or failure of theobject which is located beneath the unit.4.1.1 Installation site requirements of theoutdoor unitMind the following spacing guidelines:≤1200>100>100>50>350>350(mm)(mm)abbaa Air outletb Air inletNOTICE▪ Do NOT stack the units on each other.▪ Do NOT hang the unit on a ceiling.Strong winds (≥18 km/h) blowing against the outdoor unit’s air outletcauses short circuit (suction of discharge air). This may result in:▪ deterioration of the operational capacity;▪ frequent frost acceleration in heating operation;▪ disruption of operation due to decrease of low pressure orincrease of high pressure;▪ a broken fan (if a strong wind blows continuously on the fan, itmay start rotating very fast, until it breaks).It is recommended to install a baffle plate when the air outlet isexposed to wind.It is recommended to install the outdoor unit with the air inlet facingthe wall and NOT directly exposed to the wind.babca Baffle plateb Prevailing wind directionc Air outletDo NOT install the unit in the following places:▪ In places where a mineral oil mist, spray or vapour may bepresent in the atmosphere. Plastic parts may deteriorate and falloff or cause water leakage.
