Also read the precautions and requirements in the general safety precautions chapter 52
In any case provide at least 300 mm of free space below the unit additionally make sure the unit is positioned at least 100 mm above the maximum expected level of snow see 7 mounting the outdoor unit 4 71 for more details 52
In heavy snowfall areas it is very important to select an installation site where the snow will not affect the unit if lateral snowfall is possible make sure that the heat exchanger coil is not affected by the snow if necessary install a snow cover or shed and a pedestal 52

If the total refrigerant charge in the system is 1 4 kg i e if the piping length is 27 m you need to comply with the minimum floor area requirements as described in the following flow chart the flow chart uses the following tables 14 table 1 maximum refrigerant charge allowed in a room indoor unit 4 224 14 table 2 minimum floor area indoor unit 4 225 and 14 table 3 minimum venting opening area for natural ventilation indoor unit 4 225 55
Information 55
Multiple indoor units if two or more indoor units are installed in a room you must consider the maximum refrigerant charge that can be released in the room when a single leak occurs example if two indoor units are installed in the room each with its own outdoor unit then you have to consider the refrigerant charge of the largest indoor outdoor combination 55

Brazing 82
Copper brazing filler alloy bcup which does not require flux flux has an extremely harmful influence on refrigerant piping systems for instance if chlorine based flux is used it will cause pipe corrosion or in particular if the flux contains fluorine it will deteriorate the refrigerant oil 82
Do not use anti oxidants when brazing pipe joints 82
Do not use flux when brazing copper to copper refrigerant piping use phosphor 82
Installation 82
Of oxidised film on the inside of the piping this film adversely affects valves and compressors in the refrigerating system and prevents proper operation 82
Residue can clog pipes and break equipment 82
Set the nitrogen pressure to 20 kpa 0 bar just enough so it can be felt on the 82

Charge the system with nitrogen gas up to a gauge pressure of at least 200 kpa 2 bar it is recommended to pressurize to 3000 kpa 30 bar in order to detect small leaks 86
Check for leaks by applying the bubble test solution to all connections 86
Connect the vacuum pump and manifold as follows 86
Connect the vacuum pump to the service port of the gas stop valve 86
Discharge all nitrogen gas 86
Do not exceed the unit s maximum working pressure see ps high on the unit name plate 86
Does not change there is no moisture in the system this procedure is finished 86
If the pressure then 86
Installation 86
Leave as is for 4 5 minutes and check the pressure 86
Make sure that the gas stop valve and liquid stop valve are firmly closed before 86
Make sure to use a recommended bubble test solution from your wholesaler do not use soap water which may cause cracking of flare nuts soap water may contain salt which absorbs moisture that will freeze when the piping gets cold and or lead to corrosion of flared joints soap water may contain ammonia which causes a corrosive effect between the brass flare nut and the copper flare 86
