- The analysis of major installation problems experienced is shown below 20
- The installation is of vital importance 20
- Note 1 the division of the work should be thoroughly clarified this applies particularly to work relating to the connection of control wiring fitting of remote control and central control panel boundary work on areas such as connection of drain piping and humidification supply piping inspection and foundation 2 keep a constant check on the progress of the construction work to avoid deviations from the air conditioning work schedule 3 for sleeve and insert work the positions of ceiling girders should be confirmed and sleeve and insert requirement hole diameters positioning and numbers decided this is particularly important in the case of sleeves for drain piping 21
- Striking a balance between system installation and general construction work comprehensive flow chart 21
- At the contract drawing stage the following points are critical 22
- Contract drawing 22
- Objectives include the drawings should be easily comprehensible to those carrying out the work the contents of the drawings should not be subject to subsequent alteration 22
- Points to bear in mind when preparing the contract drawings 22
- The following is a list of the main points to be considered when preparing contract drawings for the iii system and should be used as a reference during this stage of the work 22
- The following points should be borne in mind when preparing the contract drawings from the original drawings and the execution drawings the contract drawings for the air conditioning system are blueprints for the performance of the necessary work which are drawn up on the basis of the original drawings in such a way that a working balance is achieved between the specific requirements of each individual aspect of the work 22
- For details on field settings and centralized control group no refer to the installation manual and system reference materials 23
- General information 17 23
- In addition to the design of the appropriate this system configuration it is also essential that the control system be made amply clear if the system is designed and installed without a clear comprehensive plan then problems are inevitably going to occur during the test run servicing too will become much more time consuming than necessary however if control circuit diagrams are prepared along with the contract drawings in order to make the total system clearly visible then the essential points relating to the electrical connections will be easily understood the test run will go off without a hitch and the whole system will be rendered fully effective 23
- Main considerations in preparation of control circuit diagrams 23
- Mark each outdoor unit with a code 2 add field settings and data for outdoor units and outdoor unit no if using sequential start 3 add the model number of each indoor unit connected to each refrigerant circuit 4 assign each indoor unit a code 5 fill in the location of each indoor unit 6 group indoor units controlled by one or two remote controls group or individual control 7 assign central group nos if using centralized control 8 add field settings and optional equipment for indoor units 9 add unit no if making separate field settings for each indoor unit under group control 23

- Table 1 correlation of nozzle tip and size of refrigeration piping 34
- The r 410a heat pump cooling only rx y q p series uses a wide range of piping sizes you should therefore be careful when selecting the nozzle tip if a small nozzle tip is used for brazing piping of large diameters such as φ 38 and φ 44 brazing flow becomes poor 34
- Brazing 35
- A stiffened pipe must always be annealed at least once prior to the flaring work b a pipe cutter must be used to cut the pipe a large pipe cutter must be used where the pipe has a large diameter when cutting a pipe which is too big for the pipe cutter a metal saw may be used but care must be taken to ensure that the debris from sawing does not get into the pipe c set the flaring tool to make sure the flare size remains within the prescribed limits 36
- D coat the inner and outer surface of the flare with refrigerator oil ester or ether oil this ensures that the flare nut passes smoothly preventing the pipe from twisting do not use suniso 4gs oil 36
- Flare connection 36

- Check 1 where pressure falls while carrying out steps 1 to 3 described on previous page check by ear listen for the sound of a major leak check by hand check for leak by feeling around jointed sections with hand soap and water check snoop bubbles will reveal the presence of a leak 44
- Check 2 when searching for a minor leak or when there has been a fall in pressure while the system has been fully pressurized but the source of the leak cannot be traced 1 release the nitrogen until the pressure reaches 0 mpa 2 increase pressure to 1 mpa using gaseous flon gas r 410a nitrogen and flon gas mixed 3 search for the source of the leak using a leak detector 4 if the source of the leak still cannot be traced then repressurize with nitrogen up to 4 0mpa and check again the pressure must not be increased to more than 4 0mpa 44
- Checking for leaks 44
- General information 44
- Important points 1 where the lengths of piping involved are particularly long then the air tight test should be carried out block by block example 1 indoor side 2 indoor side vertical pipes 3 indoor side vertical pipes outdoor side 44
- Installation sien34 705 44
- Setup of air tight test referring to following figure connect an nitrogen tank refrigerant tank and a vacuum pump to the outdoor unit the shutoff valve and valve a c in following figure should be open or closed as shown in the table below 44
- Key points lower the degree of vacuum to below 755mmhg 45
- The evacuation of air conditioner piping provides the following effects 1 vacuum drying 2 removes air and nitrogen used in air tightness test from the inside of pipes therefore it is necessary to ensure that the both purposes have been achieved in the vacuum drying operation 45
- Vacuum drying 45
- Vacuum drying is the use of a vacuum pump to vaporize gasify the moisture liquid inside the pipes and expel it leaving the pipes completely dry inside at 1 atm 760 mmhg the boiling point evaporating temperature of water is 100 c but if a vacuum is created inside the pipes using a vacuum pump then the boiling point is rapidly reduced as the degree of the vacuum is increased if the boiling point is reduced to a level below that of the ambient temperature then the moisture in the pipes will evaporate 45
- What is vacuum drying 45
- Choosing a vacuum pump 46
- 2 degree of vacuum ultimate vacuum varies largely according to use of the vacuum pump vacuum pumps used for vacuum forming cannot be used for vacuum drying a vacuum pump with a high degree of vacuum is required 47
- Degree of vacuum is expressed in torr micron mmhg and pascal pa the units correlate as follows 47
- Degree of vacuum measurement an extremely accurate vacuum gauge is required to test degree of vacuum you cannot accurately measure degree of vacuum with the compound gauge on the gauge manifold a pirani vacuum gauge is required to measure degree of vacuum accurately because pirani gauges are very sensitive and require extreme care when using they are not very suitable for use in the field you should therefore use the pirani gauge to calibrate the attached vacuum gauge on the gauge manifold and the degree of vacuum of the vacuum pump 47
- General information 41 47
- Sien34 705 installation 47
- Vacuum pump maintenance because of their nature most vacuum pumps contain large amounts of oil which lubricates bearings etc and functions to enhance airtightness of pistons when using a vacuum pump to discharge air from refrigerant piping moisture in the air tends to get mixed in with the oil you must therefore change oil periodically and make sure the proper oil level is maintained perform periodic inspections in accordance with the operating instructions 47
- When selecting a vacuum you should select one which is capable of achieving 0 torr of ultimate vacuum 47
- Calibration method 1 connect a pirani vacuum gauge and the gauge manifold vacuum gauge 0 760 mmhg to the vacuum pump at the same time and run the pump for about 3 minutes 2 make sure the reading of the pirani vacuum gauge is 5 torr 667 pa or less the reading of conventional vacuum pumps lowers to about 0 torr if the reading is not 5 torr or less check the vacuum pump oil oil is low in many cases 3 check the attached gauge on the gauge manifold adjust the gauge if the reading is not exactly correct 4 adjust the gauge manifold valve so that the pirani vacuum gauge reads 5 torr 5 mark the position indicated by the gauge manifold gauge with an oil based ink pen 6 use the mark of the gauge manifold as a target when vacuuming in the field 48

- Grouped drain piping 54
- If a drain pan made of polystyrene foam is used then an auxiliary drain hose flexible is also essential a flexible drain hose permits the drain socket and drain pipe to be connected without difficulty and prevents any undue strain being placed on the drain pan 54
- Important points 1 the drain pipe should be at least equal in size to that of the indoor unit 2 the drain pipe is thermally insulated to prevent the formation of condensation inside the pipe 3 the drain up mechanism should be fitted before the indoor unit is installed and when the electricity has been connected some water should be added to the drain pan and the drain pump checked to see that it is functioning correctly 4 all connections should be secure special care is needed with pvc pipe the use of a colored adhesive with pvc pipes will help you to remember to connect them up 54
- Installation sien34 705 54
- It is standard work practice to make connections to the main pipe from above the pipe down from the combination should be as large as possible 54
- The pipework should be kept as short as possible and the number of indoor units per group kept to a minimum 54

- Air tight test and vacuum drying 301
- Note always use nitrogen gas for the airtightness test absolutely do not open the shutoff valve until the main power circuit insulation measurement has been completed measuring after the shutoff valve is opened will cause the insulation value to drop 301
- Note the airtightness test and vacuum drying should be done using the liquid side and gas side shutoff valve service ports see the r 410a label attached to the front plate of the outdoor unit for details on the location of the service port see figure at right see shutoff valve operation procedure in 2 11 1 before working for details on handling the shutoff valve the refrigerant charge port is connected to unit pipe when shipped the unit contains the refrigerant so use caution when attaching the charge hose 301
- Preparations 301
- Referring to figure 28 connect an nitrogen tank refrigerant tank and a vacuum pump to the outdoor unit the refrigerant tank and the charge hose connection to refrigerant charge port or the valve a c in figure 28 are needed in 2 11 additional refrigerant charge and check operation the shutoff valve and valve a c in figure 28 should be open or closed as shown in the table below 301
- Air tight test and vacuum drying method 302
- Pipe insulation 303
- Checking of device and installation conditions 304
- About the refrigerant tank check whether the tank has a siphon pipe before charging and place the tank so that the refrigerant is charged in liquid form see the figure below 305
- Additional refrigerant charge and check operation 305
- Before working 305
- Caution always use the proper refrigerant r 410a if charged with the refrigerant containing an improper material it may cause an explosion or accident r 410a is a mixed refrigerant so charging it as a gas will cause the refrigerant composition to change which may prevent normal operation 305

- Liquid side shutoff valve 305
- Note do not open the shutoff valve until 2 10 checking of device and installation conditions are completed if the shutoff valve is left open without turning on the power it may cause refrigerant to buildup in the compressor leading insulation degradation be sure to use the correct tools the shutoff valve is not a back seat type if forced it to open it might break the valve body when using a service port use the charge hose after tightening the cap make sure no refrigerant gas is leaking 305
- Other tanks 305
- Shutoff valve operation procedure when operating the shutoff valve follow the procedure instructed below 305
- The outdoor unit is charged with refrigerant when shipped from the factory but depending on the size and length of the piping when installed it may require additional charging for charging the additional refrigerant follow the procedure in this chapter and then carry out the check operation 305
- With siphon pipe 305
- Φ 12 the 18hp type corresponds to the 15 diameter onsite piping using the accessory pipe 305
- Φ 25 the 10hp type corresponds to the 22 diameter onsite piping using the accessory pipe the 12 18hp type corresponds to the 28 diameter onsite piping using the accessory pipe 305
- Φ 9 the 12hp type corresponds to the 12 diameter onsite piping using the included piping 305
- Caution make sure to use the protect tool protective groves and goggles when charging the refrigerant due to a danger of liquid hammer the refrigerant must not be charged over the allowable maximum amount when charging the refrigerant do not perform the refrigerant charging operation under working for the indoor unit when opening the front panel make sure to take caution to the fan rotation during the working after the outdoor unit stops operating the fan may keep rotation for a while 307
- How to check how many units are connected it is possible to find out how many indoor or outdoor unit in the system are turned on by operating the push button on the pc board a1p of outdoor unit in case of multi system master unit follow the procedure below to check how many indoor or outdoor units are turned on 307
- Note if operation is performed within 12 minutes after the indoor and outdoor units are turned on h2p will be lit on and the compressor will not operate in order to ensure uniform refrigerant distribution it may take up to around 10 minutes for the compressor to start up after the unit starting operating this is not a malfunction 307
