■Be sure to switch off the unit before touching any electrical parts.
■Be sure to earth the air conditioner.
Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead.
Imperfect earthing may result in electric shocks or fire.
A high surge current from lightning or other sources may cause damage to the air conditioner.
■Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks or fire.
■Live parts can be easily touched by accident.
Never leave the unit unattended during installation or servicing when the service panel is removed.
■When planning to relocate former installed units, you must first recover the refrigerant after the pumping-down operation. Refer to chapter “Precaution for pumping-down operation” on page 10.
Caution
■While following the instructions in this installation manual, install drain piping to ensure proper drainage and insulate piping to prevent condensation.
Improper drain piping may result in indoor water leakage and property damage.
■Install the indoor and outdoor units, power cord and connecting wires at least 1 m away from televisions or radios to prevent picture interference and noise.
(Depending on the incoming signal strength, a distance of 1 m may not be sufficient to eliminate noise.)
■Remote controller (wireless kit) transmitting distance can be shorter than expected in rooms with electronic fluorescent lamps (inverter or rapid start types). Install the indoor unit as far away from fluorescent lamps as possible.
■Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shelter by small animals. Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep the area around the unit clean.
■Do not rinse the outdoor unit. This may cause electric shocks or fire.
■Do not install the air conditioner in the following locations:
■Where there is a high concentration of mineral oil spray or vapour (e.g. a kitchen).
Plastic parts will deteriorate, parts may fall off and water leakage could result.
■Where corrosive gas, such as sulphurous acid gas, is produced.
Corroding of copper pipes or soldered parts may result in refrigerant leakage.
■Near machinery emitting electromagnetic radiation. Electromagnetic radiation may disturb the operation of the control system and result in a malfunction of the unit.
■Where flammable gas may leak, where there is carbon fibre or ignitable dust suspensions in the air, or where volatile flammables such as paint thinner or gasoline are handled.
Operating the unit in such conditions may result in fire.
■Where the air contains high levels of salt such as that near the ocean.
■Where voltage fluctuates a lot, such as that in factories.
■In vehicles or vessels.
■Where acidic or alkaline vapour is present.
■The air conditioner is not intended for use in a potentially explosive atmosphere.
Provide a logbook
In accordance with the relevant national and international codes, it may be necessary to provide a logbook with the equipment containing at least
-info on maintenance,
-repair work,
-results of tests,
-stand-by periodes,
-etc...
In Europe, EN378 provides the necessary guidance for this logbook.
BEFORE INSTALLATION
■Important PR: Insulation resistance of the compressor.
If, after installation, refrigerant accumulates in the compressor, the insulation resistance can drop, but if it is at least 1 MΩ, then the machine will not break down.
■Turn on the power and leave it on for six hours. Then, check to see if the insulation resistance of the compressor has risen or not.
The compressor will heat up and evaporate any refrigerant in the compressor.
Check the following items if the ground-fault circuit interrupter is triggered.
■Make sure that the interrupter is compatible with high frequencies.
This unit has an inverter, so an interrupter capable of handling high frequencies is needed to prevent malfunction of the interrupter itself.
Precautions for R410A
Since maximum working pressure is 4.0 MPa or 40 bar, pipes of larger wall thickness may be required. Refer to paragraph “Selection of piping material” on page 5.
■The refrigerant requires strict cautions for keeping the system clean, dry and tight.
-Clean and dry
Foreign materials (including mineral oils or moisture) should be prevented from getting mixed into the system.
-Tight
Read “Precautions on refrigerant piping” on page 6 carefully and follow these procedures correctly.
■Since R410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid state. (If the refrigerant is in state of gas, its composition changes and the system will not work properly).
■The connected indoor units must be indoor units designed exclusively for R410A.
■Refer to catalogue for connected indoor unit model name.
If connecting indoor unit to other than specified, normal operation cannot be performed.
Installation
■For installation of the indoor unit(s), refer to the indoor unit installation manual.
■Illustrations show class 125 outdoor unit type. Other types also follow this installation manual.
■Never operate the unit with a damaged or disconnected discharge thermistor and suction thermistor, burning of the compressor may result.
■Be sure to confirm the model name and the serial no. of the outer (front) plates when attaching/detaching the plates to avoid mistakes.
■When closing the service panels, take care that the tightening torque does not exceed 4.1 N•m.

This is a class A product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures.
2When installing the unit in a place exposed to strong wind, pay special attention to the following.
Strong winds of 5 m/sec or more blowing against the outdoor unit's air outlet causes short circuit (suction of discharge air), and this may have the following consequences:
-Deterioration of the operational capacity.
-Frequent frost acceleration in heating operation.
-Disruption of operation due to rise of high pressure.
-When a strong wind blows continuously on the face of the
unit, the fan can start rotating very fast until it breaks.
Refer to the figures for installation of this unit in a place where the wind direction can be foreseen.
■Turn the air outlet side toward the building's wall, fence or screen.
Make sure there is enough room to do the installation
■ Set the outlet side at a right angle to the direction of the wind.

6When installing the unit in a place frequently exposed to snow, pay special attention to the following:
-Place the outdoor unit on a stand (field supply) so that it is not covered by snow falls, snow buildups, or snow drifts. Ensure the bottom plate is at least 500 mm higher than expected snow levels.
-Install a roof cover for a snow fence or other enclosure (field supply).
-Remove the rear suction grille to prevent snow from accumulating on the rear fins.
-Avoid installing the unit in a location where blown snow will build up.
Also take the following measures, as there is a danger the drainage discharged during defrosting operation may freeze.
-Install the outdoor unit at a sufficient height so that its bottom plate is above expected snow levels. This is to prevent the buildup of ice on the underside of the bottom plate. (A space of at least 500 mm is recommended.)
-Do not use a centralized drain plug (option). (There is a danger of freezing when a drain plug or drain pipe is used.)
-If there is a problem with dripping of drainage, take a measure such as positioning a roof cover (field supply) under the outdoor unit.
7If you install the unit on a building frame, please install a waterproof plate (within 150 mm of the underside of the unit) or
use a drain plug kit (option) in order to avoid the drainwater dripping. (See figure.)

Drain pipe disposal
■Potentially problematic locations for outdoor unit drainage
In locations where, for example, drainage may fall on passersby or frozen drainage may cause passersby to slip over, install an enclosure (field supply) to prevent people approaching the outdoor unit.
■In regions where buildups of snow can be expected, the accumulation and freezing of snow in the space between the heat exchanger and external plate may lower operating efficiency. In this case, drill a knockout hole in the lower part of the bottom frame so the snow can escape. When creating a knockout hole, use a Ø6 mm drill bit to open round holes connected to the circumference of the knockout hole (4 places).
■After punching the knockout hole, the application of repair-type paint on the surface around the edge sections is recommended to prevent rust.

INSTALLATION SERVICING SPACE
■The installation service spaces shown in these drawings are based on an outdoor unit intake area temperature of 35°C (DB) for COOL operation. If the planned intake area temperature exceeds 35°C (DB), or if the heat load of all outdoor units is increased significantly and exceeds the maximum operating capacity, secure a larger space than that indicated by the intake dimensions in these drawings.
■For installation, consider both pedestrian and airflow paths and choose a suitable pattern from these drawings to match the space available onsite. (If the number of units to be installed exceeds the patterns in these drawings, consider using shortcircuits.)
■Regarding the front space, position the units with consideration to the space required for the onsite refrigerant piping work. (Consult your dealer if the work conditions do not match those in the drawings.)
