6 Deciding on Where to Install the Outdoor Unit Outdoor Unit The outdoor unit must NEVER be placed on its side or upside down, as the compressor lubrication oil will run into the cooling circuit and seriously damage the unit. Choose a location that is dry and sunny, but not exposed to direct sunlight or strong winds. Do not block any passageways or thoroughfares. Choose a location where the noise of the air conditioner when running and the discharged air do not disturb any neighbours. Choose a position that enables the pipes and cables to be easily connected to the indoor unit. Install the outdoor unit on a flat, stable surface that can support its weight and does not generate any unnecessary noise and vibration. Position the outdoor unit so that the air flow is directed towards the open area. Maintain sufficient clearance around the outdoor unit, especially from a radio, computer, stereo system, etc. Indoor Unit Remote Controller Fuse Fuse.5m m m.5m.5m.5m Outdoor Unit Stereo If the outdoor unit is installed at a height, ensure that its base is firmly fixed in position.

13 Connecting Up and Removing Air In the Circuit ENGLISH The air in the indoor unit and in the pipe must be purged. If air remains in the refrigeration pipes, it will affect the compressor, reduce to cooling capacity and could lead to a malfunction. Refrigerant for air purging is not charged in the outdoor unit. Use Vacuum Pump as shown at the figure. Outdoor unit A C Connect each assembly pipe to the appropriate valve on the outdoor unit and tighten the flare nut. B D Referring to the illustration opposite, tighten the flare nut on section B first manually and then with a wrench, applying the following torque. Outer Diameter Torque 9.5 mm (/ 8") ~407 kgf cm 9.05 mm (/ 4") 990~0 kgf cm Connect the charging hose of low pressure side of manifold gauge to the packed valve having a service port as shown at the figure. 4 Open the valve of the low pressure side of manifold gauge counterclockwise. 5 Purge the air from the system using vacuum pump for about 0 minutes. Close the valve of the low pressure side of manifold gauge clockwise. Make sure that pressure gauge show 0.MPa(76cmHg) after about 0 minutes. This procedure is very important in order to avoid gas leak. Turn off the vacuum pump. Remove the hose of the low pressure side of manifold gauge. B(liquid) Vacuum pump 6 Set valve cork of both liquid side and gas side of packed valve to the open position. 7 Mount the valve stem nuts and the service port cap to the valve, and tighten them at the torque of 8kgf cm with a torque wrench. Valve stem 8 Check for gas leakage. At this time, especially check for gas leakage from the way valve s stem nuts(a port), and from the service port cap. 9 If necessary, install the refnet joint horizontally or vertically ; for choice of the refnet joint, refer to page 5. Note The refnet joint should be installed within 5 or less from the horizontal/vertical line. When you install the refnet joint vertically, the inlet of a joint (Part A) should face downwards. Horizontal Cabletie 0 Vertical 0 0 Fix the refnet joint insulation to the refnet joint as shown at figure. E

14 Cutting/Flaring the Pipes Connect the pipe within 50m and cutting pieces will not be gone into the pipe as being clean to pipe section. Make sure that you have the required tools available (pipe cutter, reamer, flaring tool and pipe holder). If you wish to shorten the pipes, cut it with a pipe cutter, taking care to ensure that the cut edge remains at a 90 angle with the side of the pipe. Refer to the illustrations below for examples of edges cut correctly and incorrectly. 90 O Oblique Rough Burr To prevent any gas from leaking out, remove all burrs at the cut edge of the pipe, using a reamer. 4 5 Slide a flare nut on to the pipe and modify the flare. Outer Diameter(D) Depth (A) 9.5 mm (/8").8 mm 9.05 mm (/4"). mm Check that the flaring is correct, referring to the illustrations below for examples of incorrect flaring.

15 Performing Leak Tests ENGLISH Before completing the installation (insulation of the hose and piping), you must check that there are no gas leaks. B To check for gas leaks on the... Then, using a leak detector, check the... A Indoor unit Flare nuts at the end of sections A and B. Outdoor unit Valves on sections C and D. D C Insulation Once you have checked that there are no leaks in the system, you can insulate the piping and hose. No gap To avoid condensation problems, place heatresistant polyethylene foam separately around each refrigerant pipe. Note Always make the seam of pipes face upwards. Heat resistant polyethylene foam Wind insulating tape around the pipes. Insulation cover pipe Body Finish wrapping insulating tape around the rest of the pipes leading to the outdoor unit. CAUTION Be sure to overlap the insulation Must fit tightly against body without any gap. E5

16 Using Stop Valve To Open the Stop Valve Service port Cap Open the cap and turn the stop valve counterclockwise by using a hexagonal wrench. Turn it until the axis is stopped. Axis Sealing point Note Do not apply excessive force to the stop valve and always use special instruments. Otherwise, the stopping box can be damaged and the back sheet can leaks. If the watertight sheet leaks, turn the axis back by half, tighten the stopping box, then check the leakage again. If there is no leakage any more, tighten the axis entirely. Tighten the cap securely. To Close the Stop Valve Remove the cap. Turn the stop valve clockwise by using a hexagonal wrench. Tighten the axis until the valve reached the sealing point. 4 Tighten the cap securely. CAUTION When you use the service port, always use a charging hose, too. Check the leakage of refrigerant gas after tightening the cap. Must use a spanner and wrench when you open/tighten the stop valve. E6

17 Adding Refrigerant ENGLISH The outdoor unit is loaded with sufficient refrigerant for the standard piping. Thus, refrigerant must be added if the piping is lengthened. This operation can only be performed by a qualified refrigeration specialist. For quantity of adding refrigerant, refer to page 8. Check that the stop valve is closed entirely. Charge the refrigerant through the service port of liquid stop valve. Note Do not charge the refrigerant through the gas side service port. If you cannot charge the refrigerant according to the upper steps, following these: Open both liquid stop valve and gas stop valve. Operate the air conditioner by pressing the K key on the outdoor unit PCB. About 0 minutes later, charge the refrigerant through the service port of gas stop valve. Note If necessary, refer to the pressure table classified by outdoor temperature. Outdoor unit Liquid side stop valve(service port) Gas side stop valve(service port) Ref.
