08_ preparing the installationpreparing the installationSELECTING APPROPRIATE LOCATION FOR INSTALLATIONDecide the installation location based on the following condition and obtain the user’s approval.• Avoid a place that may disturb your neighbor. Noise may occur from the outdoor unit and the discharged air mayrun into the neighborhood. (Be careful of the operation time in a residential area)• Install the outdoor unit on a hard and even area that can support its weight.• Choose a flat place that rainwater does not settle or leak.• Choose a place avoiding strong winds.• Maintain sufficient space for repairs and service.• Choose a place where you can easily connect the pipes and cables to the indoor unit.• Make sure that the condensed water dripping from the drain hose runs out properly and safely.• When installing the outdoor unit near seashore, make sure it is not directly exposed to sea breeze.If you can not find a adequate place without direct see breeze, protection wall should be constructed.• Choose a place where there is no direct sunlight.• Choose a place where it could not come into contact with snow and rain.• Choose a place where flammable gas does not leak.• Choose a place where the indoor and outdoor unit can be connected with a pipe.• Install the indoor unit away from any interfering sources such as radio, computer, stereo equipment andalso select the place where the electrical wiring work can be possible.- Especially keep the unit at least 3m away from the electrical equipment in an area electromagnetic wavesgenerated and install the protection tube to protect the main power cable and communication cable.- Make sure that there is no equipment electromagnetic waves generate.If not, malfunction of the control system may occur due to the effect of the electromagnetic wave.(For example: The remote control sensor of the indoor unit may not be received well of electronic lightingstyle fluorescent lamps, such as fluorescent lamps are in the same space when using a remote control.)• Make sure to install the outdoor unit in a safe place where snowfall will not be obstructed. The frame shouldbe installed in a place where the air inlet and heat exchanger of the unit are not buried in the snow.• A ventilation system may be required in the case the outdoor unit is installed in a closed space or room,even though R410a is not poisonous or flammable.• Install the railing around the outdoor unit to prevent falling when the unit is installed at high place of roof onthe building.• Avoid installing the units in places such as an exhaust pipe and ventilating opening exposed to corrosivegas, oxides of sulfur, ammonia gas or sulfur gas herbicides.(These places need additional anticorrosive treatments. Please contact manufacture to avoid corrodingcopper pipes or soldered parts)• Make sure to install MCU when using HR products.• When you select the location to install MCU, the location is far away from indoor rooms because therefrigerant running of MCU may create noise.• According to the condition of power supply, electric noise or unstable voltage can occur malfunction ofelectric parts or control system.(At the ship or places using power supply from electric generator… etc)CAUTION- Install the outdoor unit in a place (such as near buildings etc.) where it can be prevented from sea breeze which candamage the outdoor unit.- If you cannot avoid installing the outdoor unit by the seashore, construct a protection wall around to block the seabreeze.- Install the outdoor unit in a place where water can drain smoothly. If you cannot find a place satisfying above conditions, please contact manufacturer.Make sure to clean the sea water and the dust on the outdoor unit heat exchanger and spreadcorrosion inhibitor on heat exchanger. (At least one time per one year.) Protection wall should be constructed with a solid material such asconcrete to block the sea breeze and the height and the width of thewall should be 1.5 times larger than the size of the outdoor unit. Also,secure over 700mm between the protection wall and the outdoor unitfor exhausted air to ventilate.Outdoorunit OutdoorunitSeabreeze SeabreezeSea SeaProtectionwall OutdoorunitSeabreezeSea
