- Drainpipe installation 15
- All field piping must be completed by a licensed technician and must comply with the local and national regulations when the air conditioner is installed in a small room measures must be taken to prevent the refrigerant concentration in the room from exceeding the safety limit in the event of refrigerant leakage if the refrigerant leaks and its concentration exceeds its proper limit hazards due to lack of oxygen may result when installing the refrigeration system ensure that air dust moisture or foreign substances do not enter the refrigerant circuit contamination in the system may cause poor operating capacity high pressure in the refrigeration cycle explosion or injury ventilate the area immediately if there is refrigerant leakage during the installation leaked refrigerant gas is both toxic and ammable ensure there is no refrigerant leakage after completing the installation work 17
- Ensure that the length of the refrigerant pipe the number of bends and the drop height between the indoor and outdoor units meets the requirements shown in table 7 17
- Notes on pipe length and elevation 17

- Refrigerant piping connection 17
- Refrigerant piping with twin indoor units when installing multiple indoor units with a single outdoor unit ensure that the length of the refrigerant pipe and the drop height between the indoor and outdoor units meet the requirements illustrated in the following diagram 17

- Charging with unsuitable substances may cause explosions or accidents ensure that the appropriate refrigerant is used refrigerant containers must be opened slowly always use protective gear when charging the system 25
- Do not exceed the maximum allowable quantity of refrigerant or overcharge the system doing so can damage the unit or impact it s functioning 25
- Do not mix refrigerants types 25
- Liquid side diameter 25
- Note on adding refrigerant 25
- Refrigerant charging must be performed after wiring vacuuming and the leak testing 25
- Some systems require additional charging depending on pipe lengths the standard pipe length varies according to local regulations for example in north america the standard pipe length is 7 m 25 in other areas the standard pipe length is 5m 16 the additional refrigerant to be charged can be calculated using the following formula 25
